Winix Plasmawave 5300 Air Purifier Review

April 15, 2021 by john

The Winix PlasmaWave 5300 home air purifier can’t improve your health. Your body does that. It won’t cure your allergies. Allergies are largely genetic. But it can generate air that’s much better to breathe, giving your body its best shot at optimizing your health.

Winix took some cues from Sharp and adapted elements of that better-known company’s PlasmaCluster model.

They included 3-stage filtering, as well as microbial destruction, and then lowered the price from their Winix 5000 series. Not bad for what some people might (mistakenly) consider a knockoff!

Performance – For Rooms up to 350 Square Feet

The Winix Plasmawave 5300 air cleaner may be similar to the PlasmaCluster but it has even better performance numbers.

The CADR (Clean Air Delivery Rate) numbers are 235 for smoke, 248 for dust and 251 for pollen. The unit will handle a room size of 350 square feet (assuming an average height ceiling).

Its four separate fan speeds allow this model to let you balance noise, electricity consumption, and air-cleansing rate with a tap. Yet, even at high settings you can live quite comfortably with this PlasmaWave model.

Sitting in a home office, you’ll barely notice it above your computer’s fan even at the purifier’s top speed. The only time the fan noise becomes truly noticeable is in the normally short-lived Turbo mode. That’s initiated automatically when the unit senses ‘bad’ air, unless you turn it on manually.

Being energy star approved you may be confident too this unit works efficiently.

Construction – Attractive, Sturdy, Compact, and Lightweight!

The Plasmawave 5300 is an attractive, well-built unit. The case is sturdy, compact, and lightweight. (22″ high x 16″ wide x 9″ deep, 15 lbs.) The seals are high-quality, which helps maintain high efficiency since it eliminates the problem of air (and, therefore, particle) bypass.

Made of high-quality plastic, the case is odor free, a nice benefit for those who are sensitive to outgassing compounds that flow from some cheaply made units. Those molecules, typically VOCs (Volatile Organic Compounds), are one of the things good home air purifiers are intended to remove, so it’s great that the Winix 5300 doesn’t add any of its own.

3 Stage Purification System

Like most home air purifiers, the PlasmaWave 5300 sports a True HEPA filter, which captures at minimum 99.97% of pollutant particles down to 0.3 microns. That’s good enough to filter out all but some viruses. Many of those are 0.020-0.250 micron.

Pretty good for the most common, and in a way least important, component in an overall filtration system. Least important, because if your vacuum cleaner has a good HEPA filter you get a lot of that value already. The filter needs to be replaced about once a year.

There is, in addition, a carbon mesh filter made of activated charcoal. That not only filters out additional particulates by a mechanical sieve action but – because carbon so readily combines with many molecules – provides a safe chemical cleansing of room air.

In this case, though, that component does much more than simply the normal carbon-filter duty. It’s suffused with anti-microbial compounds that can help combat flu viruses and other nasty bugs in the air that would slip by the HEPA filter. Keen.

That carbon filter needs to be replaced about once every three months for the average home and the manufacturer thoughtfully included three spares in the box, for a year’s supply total. When it comes to replacement, the Winix filter kit #115115 includes a True HEPA filter and 4 disposable activated carbon pre-filters.

There’s another important aspect to the filtration system that deserves a section all its own: the PlasmaWave 5300′s ionizer.

PlasmaWave Ionizer Technology

In the final stages of cleaning, filtered air passes through a type of electric pulse generating negatively and positively charged ions that combine with naturally occurring water vapor (H2O) to form Hydroxyl radicals (OH). The amount of Hydrogen (H) gas produced is too small a concentration to be any kind of danger.

Those Hydroxyls act as forceful oxidizers to destroy microorganisms – bacteria, viruses, mold spores, and the like – in the vicinity. But they also combine readily with many VOCs (compounds in paint fumes, for example).

That allows the ionizer to do double duty, destroying potentially harmful bugs in the air and removing some of the organic chemicals that can irritate lungs, eyes, and nasal passages. After pollutants have been destroyed the Hydroxyls reform into water vapor (H2O) or other harmless air molecules.

This method is more effective and safer than older-style ozone generators. Those work by creating ozone (O3), an oxygen molecule with three oxygen atoms rather than the usual two. That extra atom attached provides additional energetic electrons that ‘stick out’ and zap nearby organisms. But they can also irritate lungs and sting the eyes when the concentration is high enough to do good by purifying the air.

The ionizer is controllable, too. You may notice a slight clicking noise from time to time when the ion generator is pumping out those electrically-charged, air-cleansing molecules. So, it’s helpful that you can turn it off or on as you please. If the noise is irritating, it’s a simple matter to turn on that mechanism just before you leave the room, and turn it off when you re-enter.

Does it include a Warranty?

Yes, the Winix PlasmaWave 5300 includes a 1 year warranty.

Conclusion

The Winix 5300 air cleaner operates at low-noise levels while clearing a substantial volume of air quickly. It offers reliable operation and virtually eliminates smoke, dander, and health-injuring microorganisms. I’d say that merits the phrase “healthy air in a box”.

Austin Air HealthMate Air Purifier Review

April 15, 2021 by john

Most home air purifiers have pros and cons. The Austin Air HealthMate is unusual in that both those are on the extreme side of things. The pluses are really outstanding and the minuses are a little worse than usual. Let’s dig in to the details to see why…

Construction – Very Good But Not Great For Everyone

The Austin Air HealthMate is a big rectangular box, making it look somewhat clunky. But the problem is more than just its plain appearance. That’s admittedly a subjective consideration and not very important anyway.

The true difficulty is it makes placement a little challenging. Corners are the natural spot, limiting your options. Increasing that challenge, it’s a fairly large unit: 14.5″ x 14.5″ by 23″. It weighs a whopping 45 lbs with the filter installed. Mitigating that problem slightly, the HealthMate has caster wheels, so it’s not really difficult to move the unit from one place to another.

More seriously, with only a 3-speed control switch there are no other controls or indicators. Even forgetting that people just like to adjust things and to know what’s going on, the drawback is more than just a failure to satisfy the itch for something high-tech to play with. The ability to tailor your air purifier to personal circumstances is important. Seeing how it operates in those various modes is, too.

Still, the HealthMate is well made – surprisingly well made for a unit not at the top of the line – and that is important. It’s not the cheapest air purifier by any means; it’s only near the bottom of the premium scale, not the total scale. Those truly cheap units are correspondingly cheaply made, and don’t deliver what allergy sufferers and others need: pure air. The HealthMate does, in spades.

4-Stage Filter System

By contrast with those cheap units (and giving some due credit to Austin Air), the Healthmate does a superb job of clearing a room and keeping it clear. Smoke, animal dander, pollen, and dust simply won’t be around in great concentrations after a few hours of operation.

Better still, the HealthMate has a unique filter design that does an excellent job of clearing gases and VOCs (Volatile Organic Compounds). Paint fumes, household cleaning products, and more can irritate lungs, eyes, and nasal passages even among those who aren’t particularly sensitive. The HealthMate reduces them to concentrations below normal concern, and does it fast.

Summing up:

  • Stage 1: Large particle pre-filter (removes dust and hair)
  • Stage 2: Small particle pre-filter (removes molds, pollen)
  • Stage 3: Activated Carbon/Zeolite (removes chemicals, VOCs, ammonia, odors)
  • Stage 4: Medical Grade HEPA filter (removes bacteria and many viruses)

Unfortunately, the unit sports no filter replacement indicator. You replace it when you observe the amount of air flow has been reduced. That observation is, naturally, not one you can carry out with great accuracy without special instruments. The lack is simply a weakness in the design.

Maintenance + Costs

One small downside is that the HealthMate features a combined HEPA/Carbon/Zeolite unit. Meaning: it’s replaced as a unit. That’s similar to the color ink cartridges that required you to replace the whole thing, even though you were only out of yellow.

Still, the expected lifetime of these filters and their relatively modest cost makes that a small issue. Austin has a good reputation for straight talk and that’s borne out here.

Keep in mind, though, that the figure assumes a fairly standard home environment. Daily heavy smoke, abnormal concentration of paint fumes, excessive humidity leading to unusually high mold concentrations, and high dust levels will naturally pull that number down a bit. Still, even if one lasted only three years the replacement cost and effort is not bad.

Using the brush attachment of your vacuum cleaner works great to remove dust buildup on the 360-degree intake system while a soft dampened cloth can be used to clean the other surfaces.

What will this unit add to your electric bill? Keep in mind that electric rates vary so much, as does the amount of daily usage due to variations in fan speeds. So I’m only able to give you a rough idea… The specs show that this unit operates on 135 watts on the highest fan speed setting.

Let’s imagine the worst case scenario… If the HealthMate runs continuously at the highest setting for an entire month (31 days) your consumption would be 100.44 kWh. At average electric utility rates (let’s take 12 cents/kWh) you’ll add about 12 a month to your electric bill – once again that is if the unit would run continuously on the highest fan speed.

Performance

Of course, what counts most is how a home air purifier performs. The Austin Air HealthMate will not disappoint anyone on that score.

Vented all along the bottom, the HealthMate draws air from 360 degrees. The exhaust is on the top, so it won’t blow any uncleared dust into the air.

It draws a LOT of air, too. The HealthMate is rated to run in rooms as large as 1,500 square feet. That rating is probably a little exaggerated, but not by an outrageous amount, judging by many reviews and real-world tests.

Regrettably, while it’s sucking that air, it’s not very quiet. The ratings are:

  • 50 dB(A)@48 cfm on low,
  • 55 dB(A)@180 cfm, and a truly noisy…
  • 66 dB(A)@400 cfm on high.

[Note: cfm stands for Cubic Feet per Minute.]

As you can see by those cfm figures, though, the HealthMate moves a lot of air, as we said. For this reason, the relatively modest CADR estimate of 220 is a bit misleading.

Does it include a Warranty?

The Austin Air HealthMate comes with a 30-day no-questions-asked money-back guarantee taking away all the risk. If you’re not completely satisfied with the HealthMate, you may return it for a full refund – that is within 30 days of purchase. After that the unit is backed by a 5-year warranty on materials and workmanship. The filter cartridge comes with a 5-year pro-rated guarantee.

Conclusion

The Austin HealthMate is a first rate machine at a very non-first rank price. Those who want a super quiet unit will want to consider carefully, however. Overall, this is a great unit for allergy sufferers or anyone who just wants clean air without the need for regular home air purifier maintenance.

Honeywell Enviracaire 50250 Air Purifier Review

April 15, 2021 by john

The Honeywell 50250 99.97% Pure HEPA Round Air Purifier does a fine job at a modest price. It’s far from a top of the line model, and it has its pros and cons, but it also sells at far from the top of the line price.

Construction – 360 Degree Airflow

The Honeywell 50250 is a bit of an odd duck in the home air purifier market, due to its round case. That has advantages and disadvantages.

It makes it a little tough to find a good spot to place the unit. Corners are the natural home, limiting your options. At 19 inches high and 18 inches in diameter, it’s a fairly hefty unit. Its 21 lb weight lends support to that view.

On the upside, it provides a 360 degree air flow.

Appearance is subjective, but it lacks the high-tech look of most contemporary units. The controls and indicators are somewhat limited, making it look even plainer.

An indicator light on newer models is also bright blue, so you probably don’t want to put this in the bedroom unless you like the glow.

Performance – Very Respectable CADR/ Ratio

The Honeywell Enviracaire 50250 does a good job where it counts, for sure; it cleans a lot of air very well. The HEPA filter is one reason, of course. It captures at minimum 99.97% of particles above 0.3 microns in size.

The numbers show you how much of that gunk you can expect to clear how quickly. The model number in this Honeywell line specifies the CADR (Clean Air Delivery Rate, a measure of how many cubic feet per minute of clean air are introduced to the room). So the CADR number is 250 for smoke, 250 for dust and 250 for pollen.

Those are very respectable ratings, particularly when you calculate the CADR/ ratio, which is decidedly – and happily – on the high end of things, i.e. you get a lot of clearance for the money. And it’s especially nice that it does that for all three major home pollutants. Many other models have a good number for one and a weaker number for another.

The Honeywell 50250 also purifies out of the air mold spores, dust mites, cat dander, and other allergy-inciting nasties. Unlike high-end units, it’s not really geared to clear gases and VOCs (Volatile Organic Compounds) that well, so plan accordingly.

Run this air purifier overnight in the den and you’ll see that even the normal dust you’d find on your TV screen simply isn’t there. That layer of dust you find on your coffee table – if, like me, you’re too busy to wipe it properly every day – is absent. Nice.

Noise Level – Noisy!

The drawback comes when you look at (or test) the noise levels. For a 3-speed fan it gives a surprisingly poor showing here, even at the slowest speed. You probably won’t want to stay in the room when it’s running at the highest speed, since it produces 57db. The middle setting produces 45db. Even the lowest speed generates 35db.

That’s noisy for a high-quality home air cleaner, even one in the modest price range. Working on a computer with the unit running full blast requires good concentration.

In conjunction with the noise, there is a bit of unusual vibration. Unusual, at least, for a truly well-made home air purifier. Some lemons in otherwise good models will have a slightly off-center fan. That produces vibrations similar to car tires that need balancing.

That’s not the problem here. The Honeywell 50250 can build up air in front of the HEPA filter. That causes the case to wobble a bit. That will be especially problematic on a hardwood floor or a table top if you place your purifier there. Not a happy situation.

50250-N = 50250 with Lifetime HEPA Filter

The 50250-N is an unofficial model number that is used for referring to the new version of the Honeywell 50250 which features a lifetime HEPA filter.

Note that the new model number is actually not labeled on the packaging. So apparently if you want to know what model you have, you need to look for “permanent HEPA filter” on the packaging while the original 50250 will make no reference to this.

Also the older unit has red/black packaging while the newer model is mostly white/light in color.

Maintenance and Operation Costs

The Intelli-Check electronic filter monitor sports a red light to alert you when the HEPA filter is dirty or the pre-filter needs to be replaced and that’s a nice feature to have.

Luckily, it’s not like the “Check Engine” light on your car, which is meaningless. It’s sensor – not ‘mileage’ – driven. Keen. Even better, the indicators give you a warning, showing a sequence of lights as the filter gets closer to needing replacement. When the light stays on permanently, it’s time for a change.

The carbon pre-filter can be vacuumed multiple times before needing to be replaced.

The HEPA filter can be cleaned many times as well, especially if you purchase the 50250-N, which features a lifetime HEPA filter.

Beware that term “Lifetime” however! It’s as much a marketing term as a technical one. Long use and multiple cleanings will degrade the filtration ability of even these high-end True HEPA filters. Eventually, they do need to be replaced. How often will vary quite a bit depending on your room environment and how carefully you clean the filter.

The plain 50250 model uses a HEPA filter rated to be replaced every 1-3 years, which is still pretty good. You’ve 2 options here…

  • The Honeywell HRF-14 Pure HEPA Permanent Replacement Filter fits all current and past large sized Honeywell rounds including the 50250. Note that you need 3 of these stacking filters.
  • Another (slightly more expensive) option is to buy the one piece Honeywell 24000 Replacement HEPA Filter. It does fit the 50250 model, even though the online specs don’t say so.

Replacing that filter is supremely easy in any case, and doing so will show you how well made this unit is. Gently place the air cleaner on its side and unscrew the locking mechanism located under the base assembly to get access to the filter chamber. Inside, you can observe how well sealed things are. You can observe the absence of unwanted air bypass – which would show up as scattered dirt particles around the unit where they don’t belong – by noting the absence of dirt everywhere but the filter.

You won’t be terribly happy with the increase in your electric bill. The Honeywell 50250 consumes 50 watts on the lowest speed (high-end units less than 10), and the medium speed consumes 120 watts. The highest speed a whopping 170 watts.

Does it include a Warranty?

Yes, the Honeywell 50250 includes a 5 year warranty.

Conclusion

The Honeywell 50250 home air purifier does the job and does it well for what you pay for it. It lacks some of the nicer bells and whistles of higher-end units and is a bit noisy. If you’re looking for an air cleaner for a bedroom and hoping to sleep with the unit on this is probably not the right model for you. Still, if you’re less sensitive to background noise than others, be guided by your personal taste here.

IQAir HealthPro Plus Air Purifier Review

April 15, 2021 by john

The IQAir HealthPro Plus is one of the best, if not the very best, home air purifier on the market. That’s a bold claim, but one fully justified by the outstanding design, performance, and real-world user reviews of this remarkable machine.

Construction

The IQAir HealthPro Plus is a moderately large unit at 16″ wide x 15″ deep x 30″ high (with wheels attached) and weighs 35 lbs (with filters included). The caster wheels on the bottom make it no major effort to move from place to place, though.

The small downside is the rectangular case, which means corners are your best bet. However, that design helps it push a lot of air: up to 240 cubic feet per minute.

The HealthPro Plus is rated to cover a 900 square foot room (that’s about 30 feet x 30 feet) and it lives up to that rating in real-world tests. It does that in part by pulling air from around the bottom through an arched base and pushing it out the exhaust vent at the top.

Input and output vents are well separated to prevent the unit simply recycling too much of its own output. Dusty air goes in at the bottom and pure air is expelled out the top along all four sides.

The fan housed inside the case can push up to 700 cubic feet per minute. Filters reduce the actual output to the 240 cfm stated above. It’s also cleverly placed between the filter cartridges, making its operation quieter. The proprietary 3D UltraSeal system ensures no internal leakage.

But pushing all that air efficiently would be worse than useless unless it were well cleansed. That effort is performed – and performed superlatively – by the HealthPro’s unique filter system.

Unique Filter System – 4 Advanced Filtration Technologies

Stage 1. The pre-filter catches the largest particles – such as ordinary dust and some pollen carriers. The mini-pleat design offers a large surface area to carry out that task well and for a long time before needing replacement.

IQAir’s PreMax pre-filters remove 90% of particle mass, compared to the 20% of many others. This first stage also helps lengthen the life and increase the efficiency of the next stages.

Stage 2 + 3. One of the most important steps is then done by IQAir’s patented V5 filtration unit. This wide-spectrum gas and odor filter unit soaks up odors and many common household gases – paint fumes, ammonia, and more.

This filter unit combines two types of media – tiny carbon pellets and an aluminum substrate that is infused with potassium permanganate, a disinfectant. That means it not only scrubs odors but kills microorganisms, too.

In fact, this filter is so efficient that some buyers mistakenly believe the unit performs poorly. Behind that paradox lies an interesting tale.

When a filter like this one picks up odors, it eventually becomes saturated. Then, those odors get pushed back into the air by the force of the machine’s ample air-pushing ability. If stored for a long time in an environment where those fumes are present, the filter can become half-filled before you buy.

That leads in some cases to buyers believing the unit produces a foul smell. It doesn’t. It’s simply been so efficient before being turned on that the filter needs replacement. Regrettably, unlike some units, the HealthPro’s filters are not wrapped in plastic before being packaged inside the housing. The solution, if the problem occurs at all, is simple. Get a spare carbon filter and have one on hand.

The bottom line is that the V5 filter not only works, it works so supremely well that the odors are in the unit, not your room, long before you know you have a problem.

Stage 4. The HEPA filter installed is, in one sense, “standard equipment” these days. But that standard is so high today that people naturally take it for granted. The HealthPro’s version goes beyond the norm, though.

This HyperHEPA filter, as the Swiss company calls it, is tested and certified to filter particles down to 0.003 microns. That’s 10 times smaller than a small virus. This particular HEPA filter has been through European Norm EN 1822 testing and passed with flying colors. And, believe me, Europeans are very attuned to air quality and health issues.

Those filters’ actions combine to ensure your room gets cleared of dust and dust mites, pollen, animal dander, mold spores, and a whole range of other allergy-inducing compounds. You also won’t suffer the ill effects of common household gases nor the irritation of cat litter smells, cooking odors, and more.

Filter Replacement

Another fine feature of the IQAir HealthPro Plus is that each of these filters is entirely separate, though they work together inside the purifier. You replace them one at a time, as needed. Other units, while good in many respects, have integrated filters that force you to buy the whole thing when only one aspect is saturated.

Also great, you have to replace them very seldom even in the most frequent case. The average lifetime/replacement ratings are:

  • PreMax Filter: 6-18 months
  • V5-Cell Filter: 1-2 years
  • HyperHEPA Filter: 2-4 years

Filter Life LEDs indicate the state of the individual filters in the system and thanks to a built-in Filter Life Monitor you know at any given time how much time is left before you need to do a filter replacement. So, you need never keep track of when you bought the unit or last replaced a filter.

IQAir HealthPro vs IQAir HealthPro Plus

IQAir also sells a standard HealthPro unit. The biggest difference between the 2 models is that the HealthPro features the same advanced filter technologies as the HealthPro Plus, however without the V5-Cell filter unit.

Thanks to a spare compartment the HealthPro model can be upgraded to include this filter stage. After upgrading, the HealthPro will filter gaseous pollutants and odors, in addition to allergens, dust and other airborne particles just as its HealthPro Plus cousin.

  • HyperHEPA filter module
  • V5-Cell filter module
  • PreMax filter module
  • Set of casters
  • Remote control + batteries
  • User Manual
  • Quick Start Guide
  • Certificate of Performance

Does it include a Warranty?

The IQAir HealthPro Plus is backed by a 5-year warranty against defects in parts and labor. Filters are consumables and exempt from this warranty.

What Are Others Saying?

You can rest assured that all the good comments (including mine) about the IQAir HealthPro Plus are not hype. Each unit is tested by the manufacturer and certified as it comes off the assembly line.

The HealthPro Plus has received numerous awards showing that those manufacturing efforts have been successful. The HealthPro has won:

  • Allergy Buyer’s Club: Category Winner
  • Wired Magazine Test: Best Air Purifier
  • Reviewboard Magazine: Product of the Year
  • Consumer Digest – Best Buy

Conclusion

The IQAir HealthPro Plus has a well-deserved reputation as “the king of the home air purifiers”. Far from being an exaggeration, this model has proven itself in real-world applications. It carries a hefty price tag, but if you want one of the best air cleaners on the market, you can’t go wrong with this model. You definitely get what you pay for: clean air and plenty of it.
