Air Purifier Advice

Mike H. (Detroit) phoned one day to say:

“I wouldn’t recommend any air purifier Home Depot sells in their store. They don’t know squat about air purifiers, and they don’t even warranty the products they carry”.

He was frustrated having wasted time buying an air purifier from with poor advice given in the store. The purifier he bought not only didn’t offer him any allergy relief, it didn’t collect any pollen in the filters when he opened it up. However the Customer Service (in the store) was good and he received a full refund.

I told Mike:

“You can’t expect expert advice from Home Depot on air purifiers, since they don’t have an in-house expert in health matters. You first have to know which technology matches your needs, and then which models have that technology, before you should even search for a good price. Do you know about the 10 technologies and what they do?”

“Nope”

He then asked me what I thought of the Ionic Pro, the model Home Depot recommended, and which was on sale there. I told Mike that the ionic pro does not have a HEPA filter – the technology he needed most for dust and pollen effectiveness.

He then asked me for suggestions in buying the right air purifier. This review offers my suggestions to Mike, plus all the reasons to avoid, or buy, an air purifier from a big box store or their online website.

10 Technologies – and what they do

Air Purifier Home Depot Brands

Home Depot Carries the Following models online:

RabbitAir

Honeywell

Winix

Blueair

Ionic Pro

GE

HomeDepot.com Problems

Target, Home Depot, and Lowe’s all sell air purifiers on their sites. Before buying any air purifier home depot (or any of the other “big box stores”) sells check the following:

1) Do they have the best price on the model you want? Remember – they are just a middleman and don’t actually carry, or service, the item. They just have it drop shipped from the manufacturer.

2) Is the warranty the same there as with the manufacturer? In many cases I’ve seen that the original manufacturers offer longer warranties if you buy direct.

3) Are prices on Amazon lower? Amazons return policies are better than Home Depot. You’re better protected, and most often the price there is lower. (However check the warranty on Amazon, and the price on the page of the manufacturer as sometimes Amazon is more).

Conclusion

If you know the ten technologies (see the video), and you have compared several brands that match your needs (see the comparison chart and reviews) then shopping online at Home Depot, Amazon, Ebay, etc. is a good way to get the best price.

If you get the same price from the manufacturers site as from the reseller (Home Depot, etc.) I suggest you buy from the manufacturer, as you’ll be able to deal directly with them if help is needed.

Overview

The Air Purifiers Ratings Charts, video reviews, and particle tests you will find on this website represent the most extensive compilation from my 30 year experience in the air purifier industry. My hope is that it saves you time and helps you to find the best air purifier for your needs, at a reasonable price.

While most air purifiers ratings charts found on the internet only reflect the top-selling units (not necessarily the best for you) of that website I’m going to suggest you watch the video below first. This video will educate you about the ten types of purifier and what each does.

Which Type Fits Your Needs?

The Best One For You

Did you watch the video? Do you understand the ten types of air purifier technology and which fits your needs? I emphasize this because I have seen many people spend time returning an air purifier that doesn’t fit their needs. A few minutes getting educated will save you money and aggravation.

How We Determine An Air Purifiers Ratings

To rate an air purifier I use the following criteria:

Available Technology- Which of the ten technologies are in the air purifier? Many air purifiers only use 2-3.

Replacement Filter Cost- I have found that most air purifiers on the market have overpriced replacement filters. For this reason the comparison chart includes these prices.

Particle Tests- This determines whether dust and pollen are taken out of the air. It surprises me that more companies do not provide video particle tests, especially for people with allergies.

Customer Reviews- Almost all air purifiers reviewed on this site are ones that I own, as witnessed by the video reviews on most brands. However it is the customer reviews on Amazon and other websites that has helped find flaws and problems with Air Purifiers which I include in my reviews.

Internal Video Review- Talking about an air purifier is one thing, taking it apart is the best way to really see what it can do. When I take apart an air purifier I can see the motor design quality, construction quality, filter size, and technology. You’ll see me do this in many of the video reviews.

Specifications – Included in each review are extensive specification information on each air purifier.

Air Purifiers Ratings

Then, along with the criteria about I give it my own personal score, using the following information:

1. Technologies Included: (out of of 10 technologies)

2. Particle Removal (Allergens, Dust)

3. Immune System Threats (Germs, Virus, etc.)

4. Gas Removal (Odor, Chemicals, Smoke)

5. Longevity/Quality

6. Noise Levels

7. Ease of Use

8. Warranty

9. Customer Service/Reputation (reviews)

10. Price Value

Conclusion

Knowing the technology, and the square footage you need, continue below to the comparison chart. After you have chosen several air purifiers watch and read the reviews on this website.

 

Overview

An Air Purifiers Ratings will only be of value if you first know:

1) What technology matches your needs (Ionic? HEPA? UV? Carbon?)

2) The value of the models you are reviewing (Consumer reviews, operating cost, filter replacement costs).

3) What square footage you need and

4) All the in’s and out’s of warranties, and guarantees

To determine the best air purifier – and that is the best based on YOUR NEEDS – my suggestion is to first watch the video below. It explains the 10 air purification technologies available and what they do.

Once you determine which technology matches your need then review the comparison chart (link on the left menu) for models that match. Choose several that match your needs. Then watch the video reviews on each model and the complete written reviews which include particle tests, as well as lists of pros and cons.

What Makes This Site Unique

While most sites offer an purifiers ratings based purely on spec sheets or price on this site you’ll find the more important information including:

1) Video reviews where I take the air purifier apart to show you the filters and technology.

2) Comparison charts – this especially important information because many companies use deceptive warranty policies and have overpriced replacement filters.

3) Particle tests which show which units really remove dust, pollen, and other debris in the air. I haven’t found any other site which covers this. (video)

How Most Air Purifiers Ratings Deceive Consumers

If you chose your air purifier before learning the 10 technologies matches you will likely choose poorly. In fact most consumers buy based on infomercials. Here’s a few things you’ll want to consider:

1) Every air purifier covers a different area of square footage, yet many consumers purchase models that are too small or too large.

2) Each of the ten air purification technologies removes something different from the air. For example, many people bought the Oreck Air Purifier for pollen allergies, only to find that it doesn’t have a HEPA filter – hence it won’t do a very good job on pollen.

3) When the air purifiers ratings come out in consumer reports they fail to include include important factors like replacement filter costs. EX: Buy their best-rated air purifier and you’ll be paying 75 every 9 months.

Got Allergies: Watch the Particle Tests

The only way to properly test whether an air purifier removes dust, dirt, or pollen is a laser particle tester. And this is perhaps the only site where you’ll find particle tests on most major brands.

Video Reviews For The Best Choice

I like seeing inside things I spend money on. And I’ve bought many good and bad air purifiers. They’re not cheap! Since air purifiers are only as good as the fans, filters, and technology inside I’ve put together a video review for the majority of air purifiers reviewed on this site.

 

OVERVIEW

On this site we have created the best rating air purifier reviews. The reason we claim that is because there is no other site that includes: specification sheets, particle tests, and complete video reviews which take you inside each air purifier.

Best Rating Air Purifier ?

Many websites claim to have the most definitive rating methods but the problem is that each persons air purifier needs are different. Here are several examples of why there can be no “best rated air purifier”:

Small Room? Most best rated air purifier s are the larger models.

Mold Problem? HEPA air purifiers are ineffective for mold, yet the best rating air purifier on the market is a HEPA air purifier.

Asthma? You would be ill advised to buy an Ozone air purifier as it can irritate sensitive lungs and trigger asthma.

How About Consumer Reports ?

While you might review the Consumer Reports Magazine best rating air purifier list (from a few years ago) for information “best” does not equal “best for you”. In fact one of their top rated suggestions – the Friedrich Air Purifier – is a huge, loud machine which is less than effective at dust and pollen being an “electrostatic ” machine. (See my review on the Friedrich).

Particle Tests

The value in particle tests is they reveal which air purifiers do an effective job at removing dust, pollen, and some bacteria. The particle tests of the major brands on this site (via the left menu) show how well each does for particle removal.

Bacteria Tests

A bacteria test can be a way to determine the effectiveness of an air purifier in getting rid of bacteria, germs, mold, bacteria and in some tests viruses. The primary methods to accomplish this through an air purifier is with Ultraviolet light, Tio2, or with Ozone.

Most air purifier are not tested for this, and while germs, bacteria and viruses may not be your primary concern it can be a consideration. If you have allergies and asthma, for example, dust and pollen would be a first concern. However viruses and germs can trigger asthma and allergies as well, and weaken an already compromised immune system.

Decibel Tests

The primary reason for looking at volume tests (volume is tested in decibel) is to determine:

Will the air purifier be quiet enough that it doesn’t disturb my sleep?

Will I notice this air purifier on while I am watching TV or doing work?

For sleep anything under 20-25 decibels is considered quiet

A Better Rating Method

A better method to determine the best air purifier for you is to create your own rating system based on “your needs”. First determine which technologies you need, then how much square footage you want to cover, and compare features using the comparison chart on this site, and then watch view reviews to narrow your search. Otherwise you are going by someone else’s rating as to which one they feel is best, but not necessarily the one that fits your need.

 

Overview

The realization that my Air Purifier was a poor financial purchase didn’t happen until 7 months later when I went to buy a replacement filter. This 220.00 machine was now asking me to spend another 120 to replace the filter. The filter was gray and clearly dirty from the auto pollution, pollen and dust in my home air, so I was clearly happy with the results, just not with the financial bath I was about to take.

The HEPA filter itself is a cloth-based filter which captures and permanently holds particles. Most can collect molecules down to 99.97 percent. It is recommended most by Allergists because nothing else does as good a job. Electrostatic and ionic plate air purifiers (like Oreck) are not anywhere close to doing a good job on dust and pollen. They simply do not collect particles as well.

Why so Expensive?

While HEPA filters are very inexpensive to produce manufacturers know they own you: If you own the air purifier then you’re basically stuck buying the replacement filter at the price the company sets for it. Most filters are now made in China.

In Japan consumers are smarter – they look for additional filters included with any air purifier purchase. Because most Americans don’t think about “down the road’ costs the air purifier makers can charge whatever they want. They often make more money on filters over 2 years than they do on the original air purifier sale itself. The same realization holds true for Auto Makers and inkjet Printer manufacturers: The real money happens in the backend.

HYPE

There are variations in sizes and shapes but none of it makes much difference in effectiveness. The difference is that bigger one will last longer and cover a larger room (if the fan is also bigger). Marketers will use the following terms to try to make theirs “sound” or “appear” different:

“True HEPA” – A term used to imply that some brands are not the real thing. If it says HEPA (and not any variation) then it is. The exception is terms like “hepa-like” or “Washable” filters. These are less-effective than the “real thing”.

“Hyper” – Different companies often try to make their filter sound better or more unique. Some have bacterial agents to kill germs and viruses. However this just kills the viruses and germs on the filter itself, not in the room.

“Sealed” – Marketers also use the term “sealed” to infer that some machines leak air out the sides of the filter making it less effective. Having reviewed, particle – tested, and owned hundreds of air purifiers (over 40 years worth) I have never seen this happen in any High Efficiency Particulate Air Purifier on the market.

Conclusion

Being just one the 10 types of air purification technologies, it is still best for allergies and the first choice I suggest in buying an air purifier.

Particle tests and comparison charts on this website will show you different models and the most popular filters inside each machine. To compare filter prices see the comparison chart via the link below.

 

THE 5 AIR FILTER HOME PURIFIER MISTAKES MOST PEOPLE MAKE…

In my 30 years in the industry I’ve tried to help people avoid these 5 mistakes:

#1 – Purchasing an air purifier that fails to cover the proper square footage

#2 – Getting a good buy on an air purifier only to find the replacement filters are overpriced 6-9 months later (very common)

#3 – Choosing the wrong type of purifier for the job (EX: purchasing an electrostatic purifier, like the Oreck, for allergies only to find that without HEPA it works poorly on dust and pollen)

#4 – Having an air purifier break down, only to find a very limited or short term warranty

#5 – Purchasing a loud air purifier which keeps you awake at night

HOW TO AVOID THESE AIR FILTER HOME PURIFIER MISTAKES …

Take these 4 steps and you’ll stay on track:

STEP #1: Review the 10 types of purifier to determine which fits your needs (WATCH THE VIDEO BELOW or text below)

STEP #2: Look at the Comparison Chart (link at bottom or via the right menu) to match type, square footage, and problem area.

STEP #3: determine the right square footage square footage, and problem area.

STEP #4: Watch the video reviews, spec sheets, particle tests, etc. from the models that fit your criteria on this site.

You’ll discover a complete review on pretty much every brand name Air Filter Home Purifier on the market. The left menu lists the top brands, and the “more” tab offers a complete list of all 85 air purifiers reviewed.

STEP #1 & 2 – 10 Technologies & SQ Ft.

There are 10 primary Purifier technologies available. The video below covers all 10, what they help, and square footage.

To Review:

#1 HEPA – For Particles including dust and pollen

#2 UV light – To Kill germs, viruses, and bacteria

#3 Active Carbon – For Gases: smoke, chemical fumes, and odors

#4 PreFilters – For large particles: Pet Hair, hair and Dust

#5 Tio2 – Improves UV effect making it much more effective

#6 Ozone – Great for Gases: Smoke, odor, mold (But can hurt lungs)

#7 Negative Ions – Can remove some smoke and pollution but more important has a positive effect on the physical body (better sleep, breathing, and more energy)

#8 Electrostatic Plates – pollution (soot), smoke, odor

#9 Water – Can gather dirt, hair and dust.

#10 Ionizers – Collects pollution and will kill some odor and smoke.

Keep a list of the technologies you want as you look at the comparison chart (Step #3) to find models matching your needs.

STEP 3-4

STEP #3 Now that you know which technologies you want, and have your square footage calculated you can continue to the comparison chart via the left or right menu.

STEP #4 The left menu lists major brands. Each page offers specs, video and written reviews, and in many cases particle tests as well. For additional questions please send me an email via the “ask a question” link at the top of the page.

 

Overview

Before you choose a home air purifier system make sure you understand the ten technologies, and how they match (or fail to match) your homes needs. That’s where I find most people end up wasting money. One example is a friend who purchased an “electrostatic” air purifier from a TV infomercial because he wanted to reduce his allergies. Unfortunately electrostatic does not work great on dust and pollen, despite the TV claims.

I am going to suggest watching the video below which educates you to:

1) The 10 air purifier technologies explained

2) Square footage measurements and square footage issues.

After gathering that info then reading our comparison chart (see the left menu for it) and watching the video reviews and specs on each model will help you choose the best air purifier system for your needs.

Already understand the technology? You can find video reviews and specs on almost every home air purifier system via the left menu. We have tested and reviewed over 200 models to date.

Top Air Purifier System Mistakes

When it comes to air purifier systems many consumers make these mistakes:

1 – Wrong technology. EX: The Oreck Air Purifier can handle smoke and odor in a small room (8 x 10) but works poorly on dust and pollen because it lacks a HEPA filter. HEPA, a cloth-like filter, is what Allergists recommend most.

2- They overpay. Air Purifiers are very profitable items, and infomercial models are often seven times cost.

3 – Too small. Without calculating the proper square footage you will likely choose an air purifier that is too small for the area you are trying to cover.

4 – Replacement filter costs. Most air purifier companies charge too much for HEPA filters and UV bulbs. Every 6-9 months on average you will have to replace these filters. Many air purifier systems can actually cost you more in filters over a year or two that the price of the purifier itself. The comparison chart on this site reveals the different replacement filter prices.

Conclusion

I hope I encouraged you to become an informed consumer and you have a better idea of what technologies match your needs. There are so many air purifiers out there it is easy to become confused and overwhelmed.

I have owned several air purifier ionizers since 1967. Now if you don’t know the difference between an ionizer, an ozone machine, and/or the 8 other types of air purification I suggest you watch the video below for an explanation.

I original bought several ionizers for help with asthma and allergies. Unfortunately they actually brought on an asthma attack. I didn’t know why but years later the Sharper Image “ionic Breeze” model was removed from the airwaves for the reason that caused my attack.

Air Purifier Ionizers Can Be Dangerous

It’s ironic that a machine purchased to clean the air for better health can actually harm you, but it’s true. The danger is not in the ionization itself but in a common by product: The washable “plates” in many of these air purifier ionizers creates ozone. While ozone can clear smoke and odor too much ozone can irritate or damage lungs and airways.

This fact has also created a lot of confusion amongst consumers who don’t know the difference between ions, ionizers, negative ionizers, and ozone air purifiers. in fact the term “ionizer” was made so popular by the ionic breeze model that many people think ionizer is synonymous with “air purifier’.

Safe Ionizers

While the most popular washable plate models do create ozone all ionizers do not produce Ozone. There are exceptions – Ionizers that use very small plates, or better yet grids (which look more like cheese graters than cookie plates) tend to produce little or no ozone.

If, after this review, an ionizer still fits your needs, you’ll have to do some research. If you have a small room to clean a small ionizer might work for you, and might be safe from ozone. Check with the manufacture, or reviews on this website to find out.

How Do Ionizers Work?

An Ionizer cleans the air as it passes through the unit. Using charged plates (electricity that is both + and -) it attracts charged molecules like a magnet. The Oreck (with it’s washable Truman cells) and the Sharper Image Ionic Breeze (with it’s many plates) are the most well known air purifier ionizers.

The flat “plates” have a tendency to create ozone because of the positive electrical charge across these plates. So while being inexpensive to manufacture, purchase, and maintain the ionic or ionizer type of air purifiers have had a big safety problem. But there are other downsides as well.

Ionizers Won’t Help Most Allergies

Despite infomercial claims air purifier ionizers are pretty ineffective for pollen or dust allergies. Because dust and pollen have little to no electric charge the plates are pretty useless. However if the ionizer also includes a pre-filter (which is like a screen door that the air goes through before the plates) it will hold some of the dust pollen and pet hair. But even a prefilter is not a very effective means of removing allergens.

Ionizers will help remove smoke and odor, and if this is your only allergy it might work for you. For allergies to dust or pollen you really need a hepa filter.

Conclusion

If you have a problem with smoke, pollution or odor any ionizers on the market will probably work for you in small rooms. I wouldn’t pay very much for an ionizer, and I’d watch out for ozone.

If you have dust or pollen allergies then I’d look at HEPA first.

 

Scams??

Perhaps “sneaky marketing” is a more fitting word.

Here is a list of some of the deceptive practices in the industry:

Scam #1 Overpriced Replacement HEPA filters

HEPA is a cloth-like filter which captures dust, dirt and pollen. These filters last on average about 6-9 months with steady use. they vary in size and price. No other technology really helps pollen or dust like HEPA.

The SCAM = The problem is that once you’ve paid for the air purifier and go to buy a new replacement – GOTCHA!.The company can charge you whatever they want. Here are just 2 examples of replacement filter costs in popular models that seem a bit inflated:

Honeywell 50250 = 

IQAIR = 

Scam #2: Limited Warranties

Warranties can vary so greatly that you need to read the details and look for a good 5 year warranty, along with a 30 (ideally 60 or more) day no questions asked money-back guarantee.

The SCAM = Warranties can actually make profit for many air purifier companies. EX: The Oreck Air Purifier is pro-rated – in a short period of time you’ll have to pay a percentage that actually makes the Oreck company money because the manufacturing costs them very little..

It reminds me of the days when American cars would not make it to 100,000 miles. Some said that it was to sell parts by breaking down as planned. Otehrs said that because the Japanses cars would last longer that American cars had to improve.

Scam #3: Claims that HEPA will work on mold and viruses.

You’ll find many Companies saying that HEPA will help mold and kill germs.

The SCAM = HEPA filters will capture some of the mold spores but will not kill mold on the walls. Those mold spores inside the HEPA can then spread. Look to include an air purifier with either UV light or electrostatic will kill mold inside and on the walls.

As for germs and bacteria – HEPA will not treat those in a room. If the HEPA is specially treated (and some are) with anti-bacterial chemicals then it will kill bacteria and germs inide the HEPA filter, but will not generally kill it anywhere else.

Scam #4 Claims That Electrostatic Ionizers Will Capture Dust and Pollen

You’ll find many Companies saying that Electrostatic will grab dust and pollen.

The SCAM Electrostatic plates and grids are positive and negatively charged electrical surfaces that will attract some particles like a magnet. Then you wash them off. And while it will capture some dust by it’s “static” charge, most pollen and dust doesn’t have a lot of charge. You need HEPA for grabbing most of the pollen and dust.

If electrostatic (Oreck’s Truman Cells are an example) really worked there would be no need for HEPA.

Scam #5 Never Have To Change The Filter???

Some models claim you never have to change the filters. That would be great, if it worked

The SCAM Washable electrostatic and pre-filters will gather some particles in the air, just not like HEPA. Also the washable “hepa-like” filters are made of foam and don’t adhere particles, or filter particle like “real hepa” filters.

Check out the reviews on this site for real information.

Conclusion

Take the steps to learn the technologies first, find out which filters you need. Figure out your square footage, and then do comparisons. A Comparison chart and video on the technologies can be found below.

A more recent list of problems:

1) Overpriced replacement filters

2) “Washable” filters that do not deliver results

3) Loud Air Purifier Fan Motors

4) Does not remove dust or pollen as promised

5) Air Purifier Limited Warranty Scams

6) Poor Customer Service

More problems listed below…

CADR Ratings For Air Purifiers Fails To Address Needs

Many air purification companies actively publicize and market their cleaners based predominately or sometimes almost exclusively on their Clean Air Delivery Rate (CADR) numbers. Others skip CADR data since many additional technologies that are different (and for many issues – better) than those associated with air flow alone, make the CADR number, at best, Irrelevant and at worse, Misleading.

CADR Does Not Factor Germs, Bacteria, Mold, Mildew, Fumes, Odors, etc.

The CADR is basically only a measure of how rapidly air is circulated through a given air filtering device. While this figure is perhaps relevant for the vast majority of filtration-only devices that attempt to clean air using only one or two types of filters, it’s meaningless because filtration is simply one single aspect. The fact is that the CADR number tells you nothing about how well, or even “IF”, an air purifier filters germs, bacteria, viruses and other harmful biological agents nor does it assess how well the unit clears chemical fumes and odors.

The easiest way to think of it is that, even though everyone in the industry refers to their products as an air “purifier”, the fact is that the overwhelming majority of competing products out there are simply air “filters” that don’t use anywhere near the number of additional “purification” technologies available, e.g., UV light, TiO2, activated charcoal, negative ionization, etc.

How to Easily Manipulate CADR Numbers

The fact is, if a manufacturer wanted to market their purifier just according to the CADR numbers, one could simply ‘beef up’ the fan speed, eliminate certain technologies and just manufacture the same limited filtration systems most companies use. For example, if you pull air too quickly through the unit in order to artificially inflate your CADR numbers, any UV technology that protects you and your family from harmful germs and viruses that traditional air purifiers miss, might negate any effects of killing germs and viruses.

The Politics of CADR

I was doing some consulting for a company who asked me about CADR and how to use these readings. It turns out that the AHAM organization (American Home Appliance Manufacturers), a political lobby group, is the organization that does the testing and certification behind CADR. It costs an air purifier company 10,000 per year to be able to use CADR in their manual or on their website. The AHAM organization represent big companies like Honeywell and Whirlpool to ‘seeemingly’ make sure politicians in Washington support their agenda. (I’m sure there are some good lobby groups but I get a little leary of lobby groups and what they have done to world views of America, to the environment, let alone to consumers. I’ve heard a few stories about AHAM I don’t like).

CADR Conclusions

CADR will give you some idea of how the air flows across your HEPA filter, but that’s about it. It won’t give you any idea of the purifier’s effectiveness in eliminating odor, gas, viruses, bacteria, etc.

Trying to find the best rated air purifier? A better question is: What is the best air purifier for my needs?

“BEST RATED” DOES NOT EQUAL BEST FOR YOU!

Despite the ratings that one might find on either Amazon or Consumer Reports there is no ” best rated air purifier “, and that is because each individuals problems are different. Some have allergies, and some have pet odor problems which take a different technology. It’s not that the information that magazines like consumer reports offer isn’t valuable, it’s just that they just provide blanket opinions and isolated reviews which have nothing to do with your needs.

A much better approach is to:

1) learn the 10 technologies available

2) calculate the square footage needed, and

3) determine which air purifiers might fit your needs.

At that point read reviews on these models to narrow your search. (NOTE: A complete video guide to finding the right air purifier can be found on the home page)

BEST RATED = SCAM

Unfortunately the term “best rated” is more often used by marketers themselves and websites that sell many brands. In many cases the most profitable air purifiers become the “best rated” models on those sites.

For our purposes here we will be taking a step beyond “best rated” and help you discover “best for my needs”. The video and 4-step process on the home page will help you accomplish this.

The air purifier industry, in my opinion, needs to provide more independent testing and research reports to the public. Even the CADR ratings are based on a political lobby group with a vested interest in the air purifier manufacturers. They do not represent the consumer.

Need for Particle Tests

As a 30 year expert in both air technologies and in the natural health field I’ve been asked for air purifier advice thousands of time. Because allergies are the most frequent problem removing pollen and dust is a primary concern. To remove dust and pollen one will need a HEPA filter which captures and holds these particles. The measure of effectiveness on pollen and dust is best determined by a particle tester. Oddly enough you do not find many particle tests on air purifiers online. If I had one criteria for the best rated air purifier it would start with a solid particle test.

This website features particle tests (VIDEO) on most major air purifier brands. This specially made particle tester measures both microscopic particles (bacteria and microscopic dust) as well as larger particles like dust and pollen. You can access particle tests on most brands by viewing the reviews via the left menu.

Need for Bacteria Tests

Germs and viruses are the second most frequent problem in the air. To remove bacteria, germs and mold one will need either Uv light or Ozone. The measure of effectiveness on bacteria and germs is best determined by a bacteria test.

While to date we have done only a few bacteria tests more are coming thanks to the university and lab we are working with. In cases where companies have done such tests from independent labs we will provide that information. Only a few companies that I know of have done so.

Conclusion

I encourage you to take the steps on the homepage of this website in order to determine the best air purifier for your needs. Start by watching the video guide which covers the 10 air purifier technologies and how to determine square footage (which is more involved than you might think).

Hopefully more air purifier companies will provide more conclusive tests to help people assess what air purifier is truly best for them.

 

Overview

Let’s start by explaining the difference between an ozone ionizer air purifier and an “ionizer purifier”, because they are two different things. I understand there is a lot of confusion amongst consumers about this, and in this article you’ll be learning the difference, and where the controversy started.

Ozone – This is a very unstable substance, which makes it good for cleaning smoke and odors from the air. However it is nothing more than oxygen which is O2 with an added molecule making it O3. So oxygen is 02, while Ozone is O3. Simple right? It’s that extra molecule, created by an electrical process, that can go out into the air and because it has a weak hold on the other 2 molecules it will attach itself and kill things like odors and mold spores.

Ozone Generating Air Purifiers

Brand names like Ecoquest, Alpine and Vollara (which are all different versions of the same company) use Ozone primarily to clean the air. The ozone goes out into the room to clean. These units deliver higher amounts of Ozone.

The danger is that ozone, with the benefit in cleaning the air, is harmful in high amounts because that unstable molecule can attach itself to lung tissue and cause irritation. Many air purifiers cannot be sold in California for this reason (which became more strict in 2011). Make sure the model you are looking for has the California Seal to be safe.

Ecoquest – Ozone Air Purifier Video

Ozone Ionizer Air Purifier

Ionizer – Another way to clean the air (used by popular models like Oreck) uses little washable plates or grids which are electrically charged with positive and negative electricity. This is called an “Ionizer” because it counts on positive and negative “ions”. Like a magnet the plates attract their opposite. Since so many pollutants are positively charged the negative plates make a perfect place for them to attach themselves. Then you simnply wash off the plates or grids. Not very good for dust or pollen they do remove odor and smoke fairly well.

This is where things get interesting. Some “Ionizers”, and other air purifiers that use these electrically charged plates or grids, create ozone. So whereas the plates were meant to carry a charge to act like a magnet, the plates were turning some oxygen into Ozone. The famous model for this was the “ionic Breeze” Air Purifier. It was taken off the market (and sharper image crashed and burned because of it) because of high levels of ozone production.

In general the “plate type” of air purifiers (especially those with big plates like the Oreck or the Friedrich”) are truly ozone ionizer air purifiers – they create secondary ozone, although their primary use is the washable plate benefit. The “grid style ( with holes in the washable plates) tends to create little or no ozone. Small ionizers (like the plug in the cigarette lighter negative ionizers) do not tend to produce ozone.

Good Ozone

Ozone, if used properly can be a good thing. I have an ozone generator myself, and I use to for:

1) Treating a room with a moldy smell or chemicals. i turn it on and leave the room until the ozone dissipates (3-4 hours sometimes)

2) Mold. Nothing works better at killing mold than Ozone. Hepa may catch mold spores, but they don’t kill mold.

Conclusion

So you can now see that an ozone ionizer air purifier is different from an ozone generating air purifier. The first creates some ozone, but is more geared toward attracting dirt, odor and pollutants onto it’s charged plates. An Ozone air purifier doesn’t have plates or grids, but simply produces ozone which goes out into the room and destroys odors, smoke and pollutants in the room.

Here’s my suggestion: Unless mold or smoke are your specific problem find an Air Purifier that uses little or no ozone, and that includes an affordable HEPA filter – because HEPA is the best for pollen, dust and allergen removal.

 

Overview

Air Ionizer Purifiers have been around quite a few years. And for many people the success of the Sharper Image “Ionic Breeze” (and “negative ionizers”) have become synonymous with air purifiers for many people when they think of cleaning the air. However there are many misconceptions when it comes to the difference between ionizers, negative ions, ozone, ionic and what they do.

Ionizer, Negative Ions, or Ozone?

Air Ionizer Purifiers – These are any air cleaning machine that uses charged particles, or ions, to clean the air. This is most often accomplished by washeable plates which have an electrical charge. Common names include electrostatic, electronic, Truman Cell, Ionic breeze and others. Air ionizer purifiers work by using this “charge” to attract dirt and pollution that often have either a positive or negative charge themselves.

Inexpensive to maintain (and manufacture) they fail to work well for anyone wanting complete particle removal as in allergies and asthma. Some air purifier ionizers can also tend to create a dangerous by product which can be harmful: Ozone. More about that in a moment.

Negative Ion Purifiers – This is different from ionizers. Instead of attracting dirt and pollution to the plates negative ion machines generate free-floating negative ions whch go out into the room, killing odor, disabling some pollution, and creating healthy air. Negative ions are naturally ocurring and needed for healthy air.

Ozone Air Purifiers – Ozone air purifiers work by taking oxygen (which has two molecules) and creating a third oxygen molecule. This third molecule is like a free-radical which leaves the air purifier and goes out into the room – killing mold and odors. It’s great for mold and odor, but too many ozone molecules can irritate or even damage sensitive lungs. Popular Brands are Ecoquest (which is now Vollara air purifiers) and Alpine (which was the original).

Air Ionizer Purifiers Can Create Ozone

The problem with some of the machines that use washable plates (EX; Oreck XL and Ionic Breeze Air Purifier) is that many air purifiers using the charged plate approach can also create ozone, even though they are not trying to. It’s just one of the effects of using charged plates.

Conclusion

If you are a smoker, and only want to clear smoke then any Air Ionizer Purifiers might be a good purchase because you can wash the plates. A HEPA Air Purifier will need often replacements because of the tar. If you want to get rid of dust and pollen then you’re going to want a HEPA air Purifier.

Better Alternatives

Here’s a Solution which includes the best of both worlds: The Alive Air Purifier uses 7 technologies:

1) Ionization – with a grid (instead of plates…DOES NOT CREATE OZONE) to clear smoke, and extend the HEPA filter life. It even extends the life of the HEPA

2) Hepa – for removing dust, dirt, and pollen

3) Negative Ions – for healthy Air

4) Carbon – for removing smoke, gases and chemical fumes.

5) A Washable Pre-filter – grabs hair and dust, extending HEPA filter life.

6) UV Light – for killing germs and viruses

7) Tio2 – for killing mold, viruses, bacteria and germs with UV.

 

Let me start off by clarifying that there is a big difference between an “Air Ionizer” and an “Ozone Purifier”. They are not the same. However it’s easy to get confused because:

“Several name brand ionizers have been found to generate dangerous ozone levels as a byproduct of their ionization methods”.

After we clarify these technologies and what each can do we’ll review the popular Ionizers and Ozone purifiers on the market. By the end you should be able to determine if they fit the type of air purifier right for your needs. Ionizers and ozone machines are also different in what they help when it comes to air problems.

Here’s the difference:

Air Ionizers – Both positive and negative ions are naturally occurring in nature, and essential to life itself. An air ionizer purifier simply creates more of them. Many air pollutants (cigarette smoke, soot, carbon fumes, etc.) are made of highly charged (+ and -) particles. Inside an ionizer air purifier you’ll often find highly charged flat plates (think “cookie pans”). These plates, charged with positive and negative ions, operate like a magnet – attracting pollution to the surface of the metal.

Ozone – Although Ozone is also naturally occurring ozone is something different than ionization. It is often created by lightning and sometimes you can smell it in the air after a lightning storm. Too much car pollution can also create ozone, and generate Ozone warnings. Oxygen is 02 (two molecules) while Ozone is a rare and very unstable “third molecule” added to an oxygen molecule (O3).

3 Types of Ionizer Air Purifiers

Now let’s review the three types of Ionizer Air Purifiers – plate, grid, and “negative ion only” type.

Plate Style Ionizers

“Plate Style” – The Oreck Air Purifier “Truman Cells” and the Sharper Image Ionic Breeze are two models that use large “plates” to attract smoke and pollution. These plate-style models have a downside however as they can produce ozone. The Ionic Breeze was removed from the market because it produced too much Ozone. These could truly be called an Air Ionizer Ozone Purifier.

Grid Style Ionizers

“Grid Style” – The grid style looks like a large cheese grater with big open holes. This style doesn’t tend to produce ozone like the plate-style. Similar to the plates in that it also uses positive and negative charges to attract pollution.

The grid style and the plate style are both usually washable and both do the same thing.

(The picture below is from the Alive Air Purifier which uses an ionizer grid as 1 of it’s 7 types of purification.)

Negative Ionizers

Negative ionizers, also called negative ion generators, produce negative ions only. Negative ions can kill mold, odor, and some pollution, although they are probably the least effective. These are also the least expensive type of purifiers and are also the one type of purification that actually has a positive effect on tissues in the body.

Negative ions have been researched to assist in breathing problems and in improving brain function. That’s why they have also been called: “Air Vitamins”

Ozone Air Purifiers

Ozone (O3) is very unstable because the third molecule dies fast and easily attaches itself to things. This makes it effective at killing mold, odor and smoke out in a room. In fact for mold killing it is probably the best. However too much ozone can cause damage in lung tissue (hence Ozone alerts which happen in many cities).

Companies like EcoQuest (now called Vollara, before Ecoquest called Alpine or Living Air) market Ozone machines for air purification. They’ve taken a lot of heat from the government (hence the name changes) because of the Ozone Problem.

Because of the air ionizer ozone purifier problem states like California have enacted strict ozone regulations and testing.

Conclusion

A better method for overall air purifying is a combination of HEPA, grid-type ionization, and UV.

 

Overview

Before delving into the air purifier reviews of Consumer Reports Magazine and consumerreports.org a little overview of their practices is in order.

Consumer reports is a federal tax exempt non profit (501 3- c) company with over 163 million in revenue and over 5.1 million subscribers, most of which now come from it’s internet subscription service. It has been known for many years, or has claimed, objectivity and accuracy in serving the public. Of course being tax exempt, yet a highly profitable organization, the public pays for both the subscription and the taxes.

Consumer Reports does not accept advertising to maintain their non-profit status as independent reviewers. In today’s day and age I don’t know if non-profits, which do bring in as much money like they do, are in the best interest of the country – given the economic hardships.

On the other hand I have used them over the years to gather info about my choices in cars and electronics. Although today I am more inclined towards the internet and the many free reviews (Amazon, cnet, etc.). The magazine, and online site, is probably a bit dated. Being in the air purifier business I always watch for the Air Purifier Consumer Report Review Issue, although I’ve been mostly disappointed in their reviews and testing. But to be fair they test thousands of items.

 

Air Purifier Rankings

While Consumer Reports Magazine (CRM) and Website (consumerreports.org) was once the #1 name in product reviews they have fallen far behind the online world, replaced by Amazon and other customer review avenues. However I still look to them on occasion when I am buying a product for additional information. I always buy (or go to the library) whenever their air purifier review comes due.

The last Air Purifier Consumer Report Review was several years ago (oddly enough it still had several models that are now considered outdated). If not for the copyright I would post it – but you can find it at the library, or subscribe for 26 online for the year.

Consumer Reports Responds

In both 2003 and 2005 their review made a scathing review of the two top TV air purifiers – the Oreck air purifier and the Sharper Image Ionic Breeze. The Ionic Breeze at the time was the #1 selling model in the world. The problem at the time was Ozone, and the fact that these two models produced enough ozone to be potentially harmful to lungs and airways. They also noted that several leading allergy and asthma foundations were offering both models their “seal of approval”.

Here’s where Sharper Image made a huge mistake. They decided to attack Consumer Reports in court to defend their Ionic Breeze. They should have let it go, because time would have probably let the controversy pass. Although I would add that they did produce high levels of ozone, so perhaps there wasn’t any controversy at all. Sharper Image, and it’s Ionic Breeze lost in Federal Court after the technical aspects were reviewed.

But it didn’t stop there. The Federal Government started looking at the Ozone issue and pretty soon Sharper Image’s ionic Breeze was pulled off the market for health reasons. Sharper Image, dependent on the Ionic Breeze to stay afloat, went bankrupt. So even though the Oreck Air Purifier also produced ozone (in smaller amounts) they escaped the wrath of the government.

Their Questionable Rankings

Most air purifier reviewers have their bias, I do, but many of us with years of experience have been baffled by many really poor models that Consumer Reports has continued to rank high. In fact some of those models, like the Friedrich Air Purifier , produce a lot of ozone – the very thing Consumer Reports rallied against and claim that it doesn’t. Yet it is ranked as the best models (May 2005). Odd. Very odd. (I own the Friedrich and take it apart in my review below. It’s big and ugly as well, more suited for industrial use than in a home)

Other models known for their effective allergy and allergen ability using HEPA filters rank very low. One such model is the IQAIR which, although very expensive, are proven effective for health conditions like asthma. Maybe the price lowered it’s rank, but there are many really, really cheap models ahead of it.

Friedrich – Consumer Reports #1

Because of the ozone problem Consumer Reports actually went to the extreme of ranking air purifiers by ozone levels rather than by true performance in 2005. Their #1 ranked Friedrich C-90A (see my video review below) came in #1 yet you’ll see by my particle test that it doesn’t do a very good job, it’s also expensive at 450, and loud despite their high marks. Plus it’s big and ugly. I just don’t get it?????

Air Purifier Consumer Report Review Comparisons

Conclusion

The more I went through the Air Purifier Consumer Report Review List of models the more problems I found which completely went opposite to the particle tests and decibel tests I have shown in my video reviews. If anyone has any knowledge of why Consumer Reports is so weak in this area please send me an email. I don’t get it!

I was even going to post the list of rankings from the most recent Air Purifier Consumer Report Review but I’m just so dissapointed in their reviews and rankings after the Friedrich (their #1 for unknown reasons) that I decided to go fishing instead…
