Is Using an Ozone Air Purifier Safe and Effective?

by

Summary

Using an Ozone Air Purifier can be effective, but many claim ozone harmful. Consumer ozone technology has been available for over 20 years. Do complete research when making a buying

decision.

Read my information realizing that it is not very technical. The In-Depth Reference section will cover the technical aspects of ozone in an easy to read format. This information is my

viewpoint after researching the subject and using the technology over the last 18+ years.

There are two main questions to be answered:

1) Is using an ozone air purifier safe?

2) Does ozone clean the air effectively?

Since you are reading this far, I'm assuming a few things. I'm assuming you have heard of ozone. I'm further assuming that you may have heard of the "ozone

controversy". Lastly I'm assuming you want either my viewpoint or you are interested in more information.

I know that assumtions can be a two-edged sword, but consider reading every word in this page including the In-Depth References. You will have a better idea of how ozone works.

More Detail

As you review Air Purifier Company websites and those selling air purifiers, you will find a trend. Most are either pro ozone or con ozone. Interestingly, the ones that sell it, prove that

it is safe and effective and the ones that don't try to warn and prove that it is unsafe. The later group generally uses common negative marketing techniques.

Ozone is a natural substance. It occurs in nature.

Did you know ozone is in the air we breathe outside everyday?

Ozone is generally measured in ppm (parts per million). This is an amount or concentration measurement. As you do research, you will find that too much concentration (too high of a ppm) can

be harmful to humans. You have to dig a little farther to find that too little also can be harmful.

It is an amount question. High concentrations are bad; too little is also bad.

Let me give you an example:

Ozone is an oxidizer. It will oxidize or "eat" certain things. It works best on living things like microorganisms (mold, mildew, and bacteria, etc). It will also clean some VOCs,

and some smells and gases.

Let's say we have a rainstorm and everything is wet. When something is wet indoors it starts to grow mold. Left unchecked, a big, bad mold problem can develop. Mold loves damp, dark

areas. If we did not have any ozone in the air outside, every nook and cranny including the trees would be covered in mold. Thank goodness for natural ozone.

What about high pollution areas and ozone?

When pollution is high, nature adjusts the ozone level higher to remove the air contaminants. After the pollution has been reduced by the ozone, levels return to normal. In cities and higher

pollution areas this can lead to some days with smog or ozone alerts. The ozone level is high because nature wants to clean faster. This high level can affect human breathing.

So, I'm stating that too much ozone is bad and too little ozone is bad; how much is good? There is a range that is deemed safe, beneficial and effective. This is where an ozone air

purifier is designed to operate. Just like any other modern technology, you need to understand how to use it.

Let me give you a few slightly humorous examples:

  • Do you jump in a shower with the scalding hot water on only? – No, you would burn yourself.
  • Do you turn up your stereo or TV full blast and put your ear next to the speaker? – No, you would make yourself deaf.
  • Do you turn your stove on high every time you cook? No, you may burn your food or burn the house down.
  • Do you slam on the gas pedal in your car everywhere you go? No, you may have an accident.

These may seem silly, but all of these modern appliances (shower, stereo, TV, stove, car) could hurt you if used improperly. Are they dangerous? The same thinking could be applied to an

ozone air purifier. As with most modern conveniences there are easily identifiable signs before danger occurs. With ozone, you can smell it and even feel it if it is too high for you. At that

point you can adjust it down. Our bodies generally will sense it just like we sense something is too hot. It is not something that "strikes you down"; you have control. Not

surprisingly there are no deaths attributed to an ozone air purifier. We can't say this for cars or stoves as well as several other everyday technologies.

I have spent literally 100's of hours researching ozone and I am still surprised at the ignorance and misinformation that is out there. Seriously! In many countries ozone is used in

many, many, many applications. Medical and otherwise. It is thought of as almost a miracle.

For detailed information, I would recommend reading the In-depth References below.

In-Depth Reference(s)

Recommended: An educational presentation on presentation on zone (opens a new window) This is "Pro" ozone.

The EPA's information on ozone (opens a new window) This is "Con" ozone.

Note: an ozone air purifier would usually not be considered an ozone generator. See my section on ozone generators for clarification.

Buying Considerations:

The question is "is an ozone air purifier safe and effective?"

The answer is "it depends."

Safety depends on the amount or concentration. An ozone air purifier usually has safety factors built into the product and operate within safe limits. Make sure your brand does.

Most air purifiers also have details on how to get the best results. In the case of ozone, settings, placement, and air flow are the important factors. Also keep in mind that ozone is

effective, but is not generally a total air cleaning solution. For example, it cannot remove dust particles from the air. It is best used in tandem with other technologies.

Many companies have jumped on the ozone bandwagon over the years. This is because making a cheap ozone air purifier is easy. Cheap technology usually isn't good. Others have down played

or removed most references to ozone as a marketing ploy. This also points to cheap products. Still others have stood their ground and advanced their research and have improved their purifiers

with additional technology making ozone a small part of the overall air cleaning process. These companies have alliances with well known organizations and reputable College Research Centers.

With that said, I would highly recommend using only products that have a good reputation and a good following.

There are two "camps" here. Those that love it and those that don't. The old technology meets the new technology. Make sure you read the In-Depth References if you are on the

fence.

You can probably guess I am pro ozone? I am because I understand it and use the technology daily. Am I trying to sell you on it? No, but I do think it is a valid technology and deserves high

consideration.

How Does Ionic Air Purifier Technology Work?

by

Summary

Most people are unaware that there are at least 4 different types of ionic air purifier in use today. Ionizers have been around for many years.

How effective are they?

A simplified explanation of the process: The ionic air purifier produces ions. The ions attach themselves to particles (opposite charges attract). The particles attach themselves to other particles or collection devices or charged surfaces and are removed from the air. The details depend on the type of ionic air purifier used. Ionization and ions are produced and are present in the air we breathe outside. Ions are measured by how many are present in a cubic centimeter or cm3. “Typical” clean air outside contains 3000 positive(+) and 4000 negative(-) ions per cm3. This amount can be influenced by a myriad of factors and is constantly changing and constantly replenished by sun, wind, and storms.

After detailed research it is my conclusion that the natural balance of ions outdoors is generally better than our indoor environments.

Have you ever felt like getting outside to get a breath of fresh air? Interestingly enough, some scientists point to +/- ions as part of the reason for outside air “feeling right”.

Now, unfortunately indoor air does presents a problem for ions. In most cases the number of ions is drastically reduced compared to outside air.

Sometimes there are too many positive ions and an imbalance occurs. Generally the imbalance leans towards the positive, but another problem could occur if too many negative ions are present. A balance is best, just like outside.

In-Depth Reference(s)

Wikipedia has general background about ionization (opens a new window)

Buying Considerations

Do your homework.

Because there are several versions of this technology, it can be hard to select the right one. I would stay away from single charge ionizers all-together. Even within the other technology types you need to search diligently for a quality ionic air purifier. Realize that there are really only a handful of companies with a “trust factor” track record. Be wary of the others as marketing hype as well as copy cats and small time vendors exist.

Lastly, the RCI version has a replaceable UV lamp or RCI cell that will need to be replaced every few years. Know and calculate the ongoing cost before purchasing.

How Does an Electrostatic Air Purifier Work?

by

An Electrostatic Air Purifier/Precipitator and an air purifier using Charged Media Filters work on similar principles. Both collect particles inside the unit.

Electrostatic technology uses electronic cells to charge particles within the purifier and immediately trap them on collector plates. These plates then can be hand washed or sometimes put in

a dishwasher.

The Charged Media technology is of the same principle, but the particles are collected in a filter. This method can collect very small particles (as small as .01 microns). The filters do

require cleaning or replacement as needed.

More Detail:

The particles are charged first, before they pass by the collector plate or collector filter. They are charged negatively (-) or with negative ions and the collector plate or filter is

positively charged (+). Just like opposites attract, the particles now are attracted to the collector mechanisms and stay there. The plates must be cleaned as often as needed or the filters

must be replaced as often as needed. If these capturing mechanisms are not cleaned or replaced as needed, the purifier will become less effective.

Both processes produce "some" ozone. In most cases it is minimal and confined to the inside of the purifier. If the ozone word scares you, make sure to understand how much is

produced and read the ozone technology information before purchasing.

Buying Considerations

There are very good, innovative, low maintenance air purifiers in this category. There are also some that are less than good. My reviews will help. As with any product with filters, do your

cost and filter replacement homework.

Why use an Antibacterial and Germicidal Air Cleaner Filter?

by

Summary

When looking for an antibacterial and germicidal air cleaner, using a specialized filter or a specially treated HEPA filter is one possible solution.

How does it work?

This technology works the same as a standard HEPA filter. It is a HEPA filter treated with antimicrobial agents to control growth of bacteria, viruses, and mold.

There are two challenges when using this type of technology for microorganism control. The first is the very small size of the "particles" and getting them to stick. The second is

"killing" the microorganism once it is trapped.

More Detail

Critical to the success of such a filter would be the purifiers ability to sufficiently contain the bacteria, viruses, and mold. The replaceable filter would need to fit tightly against any

housing that contains it. Little if any air leakage should be evident between the filter and filter housing. This may reduce air flow, but will increase the ability of the filter to collect and

trap and treat the microorganisms. Any microorganisms that slip through may be subject to the filter again and again, increasing the chance of "sticking".

There are other ways to control and remove microorganisms from the air.

See UV (Ultraviolet), Ozone, and Filterless technologies

In-Depth Reference(s)

Want to see a fun animation on the small size of microorganisms? (opens a new window) ** Make sure to increase/decrease the magnification arrows. NEW LINK REQUIRED

Buying Considerations

This feature is found mainly on high-end (expensive) air purifiers specifically designed for clean rooms, hospitals, pharmacies, and research facilities. If cost were not an option, it may

be ideal for those with serious decontamination needs or compromised immune systems. Since this method of controlling bacteria, viruses, and mold is HEPA filter related, it generally has a one

room cleaning limitation per air purifier.

Make sure to review the UV (Ultraviolet), Ozone, and Filterless technologies as they may prove more cost effective for this type of air cleaning.

What Does an Air Cleaner Pre Filter Do?

by

Summary

The air cleaner pre filter traps large particles entering the purifier protecting the purifier and extending the life of HEPA filters and other internal components.

More Detail:

A pre filter is made to keep large particles and debris from entering the air purifier. This could include hair, dust, pet fur, and other larger particles. Without a pre filter these larger particles would clog HEPA or other filters faster and causes them to be less effective. In other models that do not utilize filters, the pre filter keeps the inside of the machine cleaner and functioning better. Some air purifiers are designed to be easy to clean or require less cleaning, but the addition of a prefilter still can help minimize this cleaning.

Some pre filters are reusable and can be vacuumed or rinsed and then put back to work. The majority however are replacement filters and need to be checked and replaced as frequently as necessary. Each purifier is different and some replaceable filters life can be extended with a quick vacuuming.

“BIG” particles are a fact of life and a pre filter makes sense in almost 100% of applications.

In-Depth Reference(s)

no additional reference material – basic technology

Buying Considerations

If a purifier has no prefilter, make sure to check out how this model operates. If it is a unit with a HEPA filter, the life of the HEPA filter will no doubt be shortened. This means more cost to you (HEPA filters tend to be more expensive than pre filters). If it is a filterless type of technology, you may need to clean the purifier more often or expect a shortened life span of the internal components without a pre filter.

If your air purifier has a washable or cleanable pre-filter, realize that this may be a generous cost savings.

If your air purifier has replaceable pre filters, know the life expectancy and the cost to replace them.

Generic Air Filters a Cost Savings?

by

Will You Save Money using Generic Air Filters vs. a HEPA filter?

Summary

Companies making air filters must adhere to rigid manufacturing standards in order to use the HEPA name. HEPA is the standard. Be suspect of any filter offered at a cheaper price.

More Detail

You may see claims like:

“HEPA-type”

“HEPA-like”

“99% HEPA”

Watch out for inferior products.

The Department of Energy requires manufacturer HEPA filters to remove 99.97% or more airborne particles of 0.3 micro meter in size.

In-Depth Reference(s)

Article: The Seven Sins of Filter Manufacturers Buying Considerations: – NEEDS LINK TO NEW ARTICLE

I would recommend sticking with the original manufacturer’s replacement HEPA filter unless you are certain that the replacement filter is either a HEPA or up to the standards that the HEPA label represents.

What is HEPA Air Purifier Technology?

by

Summary

HEPA air purifier filters (HEPA – high efficiency particulate air filters) were originally designed in the 1940’s and continue to be heavily utilized today. In order for an air filter to earn the trademarked HEPA name it must pass rigid requirements including removal of 99.97% of airborne particles 0.3 microns in diameter (1 micron = 1/25,000 inch).

The American Lung Association says that “particles of 0.3 microns diameter represent the respirable size most likely to reach and be deposited in the alveoli of the lungs; they are also the most difficult to remove by mechanical filtration.”

How does a HEPA air purifier work?

A fan blows (or draws) air through a high tech filter and the particles are trapped as they pass through the filter. If the air bypasses the filter it will not be cleaned. This is a passive technology.

More Detail

Particles exist in many different types and sizes. The HEPA filter is designed to trap these particles as they pass into and through the filter medium. The HEPA filter is designed to maximize air flow and still maximize particle retention. Although the filter will become less efficient over time, it is designed to effectively do its job as it slowly becomes “plugged up”. Life expectancy depends on several factors, but generally is from 6 months to 5 years depending on the brand of air purifier. The size, material, and construction of the HEPA filter will ultimately determine it’s longevity. Higher quality HEPA filters last longer, may be larger and thus generally cost more.

What will a HEPA filter remove?

Airborne particles like Pet Allergens (.3 to 100 microns), Dust and Dust Mite Allergens (10-40 microns), Pollens (10-100 microns), Plant Spores (10-70 microns), Airborne Fungi Spores (0.5 to 5 microns), Airborne Mold Spores (2-20 microns), and larger particles of tobacco smoke (0.003 to 0.04 microns).

What won’t a HEPA filter remove?

Pure HEPA Filters do not remove most odors, chemicals, or gases as these particles are too small. The HEPA filter will not remove most VOCs (Volatile Organic Compounds) such as paints, varnishes, cleaning supplies, glues, and adhesives, nor Microorganisms such as Viruses, Antigens, Pathogens, and Bacteria. Note: some of these substances may become trapped in the HEPA filter, but removal is not guaranteed. In the case of Microorganisms, the particle(s) may become trapped but will not necessarily be killed.

HEPA filters do work effectively for what they are intended to do. One point worth repeating: The air must pass through the HEPA air purifier filter in order to be cleaned. This generally limits the effectiveness of the purifier to the room the unit is located in.

Quality air purifiers often use HEPA filters in tandem with Pre-filters, Activated Carbon Filters, and Antibacterial/Germicidal Filters and sometimes, but less often with UV Ultraviolet lights, Electrostatic Precipitators and Charged Media Filters.

In-Depth Reference

Article: The Seven Sins of Air Filter Manufacturers Buying Considerations: – NEEDS LINK TO NEW ARTICLE

Always check the recommended life expectancy of the HEPA filter for the purifier you are considering. You will generally get what you pay for. Some HEPA filters need to be replaced often, others last longer. The bottom line is there will be an ongoing maintenance cost with replacing them. Some warranties actually depend on changing filters regularly. Most importantly though, a HEPA purifier only works well with a properly maintained filter. All reviews in STEP3 include HEPA filter costs when applicable.

Buying Air Purifiers on Ebay – Read this especially if you are new to Ebay. Ebay is a great way to find good deals. There are also possible pitfalls. For best results, always read an items

description completely before bidding. If the product description is unclear, email the owner of the item a question. Do not assume anything if it is unclear. Also, only buy from someone who

has a good feedback rating. Typically someone who has at least 100 positive feedbacks with over 97% positive. Another good indicator is if a seller has been online for awhile. Be wary of new

sellers with little or no positive feedback. As you become more experienced, you may be able to successfully differentiate between good and questionable sellers without much feedback. Until

then, stick to sellers with good feedback. Some of my best deals ever are from Ebay. I use eBay often.

The Ecoquest Breeze AT is another unique air purifier from Ecoquest. It is a lot like the Fresh Air in results, but is older technology and has

less bells and whistles. It uses Active technology which means the purifier actually reaches beyond the unit and cleans the air. The Breeze AT is effective and can clean up to 2500 sqft. This

purifier is cost effective to maintain, but does take periodic cleaning to keep working in top form. Read full review for more details: Click Here for full review.

3rd Place: Ecoquest Ecobox [Air Purifier Rating 82/100]

The Ecoquest Ecobox is the newest air purifier from Ecoquest. It is a lot like the Fresh Air, but on a smaller scale. It uses Active technology which means the

purifier actually reaches beyond the unit and cleans the air. This purifier is effective and can clean up to 1500 sqft. Generally I would recommend it for a small home, smaller apartment, or

dorm room. Larger homes can use it as an extension of a Fresh Air or for the basement. The Ecobox is cost effective to maintain, but does take periodic cleaning to keep working in top form.

Air Purifier Review, Brands A-H

by

STEP 3 in our air purifier review is to compare the top brands of air purifiers on the market. This page includes brands letters A through H.

I have two types of reviews:

Actual Review: air purifiers I have personally used, tested and evaluated.- and -Additional Review: air purifiers I have evaluated without personal testing.

Important: How can I write an air purifier review without actually testing?

It is my rule to use/test at least one purifier in a brands line-up before I will write evaluation only reviews for the other purifiers in that same brands same line-up. I generally use/test

one of the brands top "parent" models to get an overall viewpoint of their entire line. A word of caution … many reviews out in "webland" are not based on actual

use/testing. Actual use/testing allows me to add much more depth and accuracy to my reviews. In most cases an evaluation only is adequate only after I have done an actual review of at least one

purifier in a given brand. Most additional models are very similar to the "parent" purifier.

Each purifier review shows an overall rating score from 0 low to 100 high. Here is the criteria I use to rate each purifier.

Or go directly to my air purifier review top 10 page.

Top Brands A to H

Enterprise Challenge award in 2006 including a check for £75,000. Air Purifier Review. I currently have five reviews posted: Mini UV, 1000 UV, 3000 UV, 3000Xtreme UV, and the 9" Induct ACT

on the internet. The company also has experts available to help you choose the correct model for your needs. I currently have seven reviews posted: Series 4000, 5000, 6000, 8000, 600, AirMedic

Bionaire:

All Bionaire Reviews

The Bionaire Company was founded in Canada in 1977. The company does international business, but available information is a bit dated. They have many models new and old and

making sense of them all is a bit of a challenge. Why they have so many models is beyond me. The units are basic technology at best and in most cases are not recommended. Lower cost, but

definitely lower cleaning power. I currently have three reviews posted: the Bionaire PERMAtech BAP2000-U, the Bionaire BAP725 QUEITech, and the Bionaire BAP1250-U.

Ecoquest Air Purifier Review:

All Ecoquest Reviews

Alpine Industries was founded in Minnesota in the Mid 80's. Bill Converse invented the technology that launched this unique line of air purifiers. Alpine had some

legal trouble in the late 90's for making claims that their air purifiers could do things they could not prove scientifically. The company changed hands in 2000 and became Ecoquest. Since,

Ecoquest has upgraded their technology, expanded engineering, established scientific proof, and partnered with leading organizations. I currently have six reviews posted: Fresh Air, Breeze AT,

have many models new and old and making sense of them all is a bit of a challenge. Why they have so many models is beyond me. The units are basic technology at best and in most cases are not

recommended. Lower cost, but definitely lower cleaning power. Rate Air Purifiers. I currently have four reviews posted with a dozen or so mini-reviews: HEPA-Type Mini Tower HAP412-U, LifeLong

HEPA-Type Tower HAP1200-U, 99.97% HEPA for Large Rooms HAP650, and the Arm & Hammer Fresh 'N Clean Odor Grabber AOR240FC-U.

Honeywell Air Purifier Review:

All Honeywell Reviews

Honeywell can trace it roots back to 1885 when Albert Butz got started in the furnace business. They are now a huge 42 billion dollar company with air purification a small part of what

is a key to choosing the right purifier.

Air Purifier Comparison of Technologies

by

STEP 1 in our Air Purifier Comparison is to understand the basic technologies. Air cleaning can be categorized by two basic terms: Passive or Active.

Some air purifiers include a combination of technologies. These could be Passive, Active or Passive/Active combining both active and passive technologies.

Let’s start with some basic definitions:

“Passive” an air cleaning process that occurs at or inside of the actual purifier. The air is drawn to the technology for cleaning.

“Active” an air cleaning process that occurs away from or outside of the actual purifier. The technology goes out to clean the air.

“Passive/Active” doesn’t apply directly to any one technology, but could be achieved if an air purifier contains multiple technologies.

Okay, this is an important distinction, so quick review: Passive = inside the purifier, Active = outside the purifier, and Passive/Active = combination of inside/outside the purifier.

Let’s Compare Each of the Key Passive Technologies:

And Finally, Let’s Review the Related Topics:

Do you need a way to rank which technologies are important to you in your air purifier comparison? Take some scrap paper and rate each technology from 1 to 10 in importance to you. When finished you will have a better idea of which technologies you find most important. Don’t worry too much about details at this point, just having a general feeling of your likes and dislikes is what we’re after.

Done comparing technologies?

Then it’s time to move along to STEP 2 Category: We’ll decide which category of purifier you want and where you want to make your air cleaner.
