HEPA Air Purification

Air Purification is more important than ever as other people (we assume not you) smog up the world. But many companies are taking advantage of the polluted world to make a fortune in air filtration.

But you will notice a serious drop in the quality of the systems after the top 10. The top 10 not only give you the best that air filtration has to offer, they do it at a cost that is cheaper than almost all low-end purifiers.

IQAir HealthPro Plus HEPA Air Purifier

#10 IQAir HealthPRO Plus

The IQAir HealthPRO Plus Air Purifier completes the top Ten. This air purifier is designed to provide superior refined particle filtration. It meets HEPA expectations but goes further by removing 99.95% of particles down to the size of .16 microns. It also has carbon filtration that will remove a moderate amount of odors and gases in the air. The refined emphasis of the IQAIR filters make them more costly. This purifier costs 67 cents per square foot of air cleaned per year. It costs $6019.20 to use for 10 years. It is backed with a 5 year warranty. It covers 900 square feet.

#12 Whirlpool AP405030K Air Purifier

The Whirlpool AP405030K Air Purifier uses carbon and HEPA filtration to clean the air. The carbon filters in this air purifier are low-end, meaning they do not have the carbon or surface area to substantially reduce odors and gases in the air. This air purifier costs 38.5 cents per square foot of air cleaned per year. It has an MSRP of $299.99 and it costs $1887.90 to use for 10 years. It covers 490 square feet and comes with a 5 year warranty. Make no mistake, #12 is a major step down in quality, performance, and cost-benefit ratio from the top 10.

#11: Healthway HW-20600-3 Deluxe DFS Air Purifier

The Healthway HW-20600-3 Deluxe DFS Air Purifier covers 1000 square feet and costs 45 cents per square foot of air cleaned per year. It costs $4485.02 to use for 10 years. It makes 58 dB of noise. It has better than HEPA filtration for satisfactory particle removal from the air. It has substantial odor filtration but not at the level of the purifiers that made it into the top ten. The company backs this air purifier with a limited lifetime warranty on the condition that you get on an autoship of their filters and replace the filters as prescribed. If you invest in this air purifier, it is worth it to do that as it will save you from having to pay replacement costs when the purifier breaks down. This is because, if you do not follow the requirements to get the lifetime warranty, then the purifier is only backed by a one year warranty.

#14: Maytag MAPG 34508w Air Purifier

The Maytag MAPG 34508w Air Purifier makes the #14 spot. It costs 39 cents per square foot of air cleaned per year. It covers 480 square feet and has an MSRP value of $299.99. It comes with a HEPA filter and carbon filter. The HEPA filter will provide meaningful particle filtration but the odor filter does not have the surface area or substance to adsorb any significant level of odors and gases. This purifier will cost $1887.90 to use for 10 years. It comes with a 5 year warranty on the motor and a one year warranty on other non-replaceable parts. This also presents a stark contrast to the quality, costs, and efficiency of the top Ten systems.

#13: Holmes HAP756-U Air Purifier

The Holmes HAP756-U Air Purifier has a HEPA filter with a carbon pre-filter. This air purifier will remove an acceptable level of particle pollution from the air. But do not expect it to do much in the way of odor and gas purification. It costs about 43 cents per square foot of air cleaned per year. It has an MSRP value of $139.99. It covers 418 square feet. It costs $1813.68 for 10 years of use. It comes with a 5 year warranty. This air purifier will not address significant air quality problems in any substantial way.

#15 Oreck Air Instinct 200 Air Purifier

The Oreck Air Instinct Air Purifier is built for good particle filtration. It has a HEPA filter and a carbon filter to address particles, odors, and chemical gases. However, it will not do much in the way of odor and gas adsorption. The carbon filter is simply not robust enough. This purifier costs 46 cents per square foot of air cleaned per year. It has an MSRP of $499.99 and covers 248 square feet. It will cost $1134.73 to use this system over 10 years. This is a low-end HEPA system that will provide adequate particle filtration. That is all its designed to do. That this system makes #15 is testimony to the limited number of truly quality filtration companies in the market. Almost all the purifiers produced by the companies listed in the top ten are better than this one.

#17: Kenmore 85450 Air Purifier

The Kenmore 85450 Air Purifier uses HEPA and carbon filtration. It has value for its HEPA filtration although we would not recommend you expect much from the carbon filtration. It costs 56 cents per square foot of air cleaned per year. It covers 401 square feet. It has an MSRP value of $299.99 and it will cost $2238.00 to use it for 10 years. It makes about 60 dB in noise. The company backs this air purifier with a one year warranty. This would be of value to someone who is only looking for particle filtration.

#16: Winix WAC5300 Air Purifier

The Winix WAC5300 makes #16 because it is at a threshold price per square foot above which the cost-benefit value becomes ridiculously poor. This air purifier combines HEPA and carbon filtration. However, the carbon filtration, like most of the low-end HEPA systems is more for the appeal than for practical functionality. It removes some odors and gases, but nothing substantial. This purifier costs 50 cents per square foot of air cleaned per year. It covers 350 square feet. It has an MSRP value of $199.99 and it will cost $1743.09 to use it for 10 years. The company only backs this purifier with a one year warranty.

#19: Bionaire BAP725 Air Purifier

The Bionaire BAP 725 Air Purifier uses a carbon and hepa filter and cleans a 256 square foot area. This purifier will provide a moderate level of particle filtration and minimal odor and gas filtration. It costs 69 cents per square foot of air cleaned per year. It has an MSRP of $98.95 and will cost $1777.40 to use it for 10 years. It is backed by a two year warranty. We consider this to be the best system Bionaire has to offer.

#18: Honeywell 50255 HD Air Purifier

Honeywell is a very popular brand but is lower on the totem pole in terms of its performance. This is probably the best of all the Honeywell models in terms of performance to cost. The Honeywell 50255 HD costs 65 cents per square foot of air cleaned per year. It covers 390 square feet and has an MSRP value of $178.00. It has a HEPA filter which gives it good particle filtration, but its carbon filter is not robust enough to do any serious odor and gas adsorption. It will cost $2537.82 to use this air purifier for 10 years. It does come with a hefty 5 year warranty which is probably the industry standard for low-end purifiers like this one. It offers a low up front cost, while costing the consumer much more on the back end for an amateur air cleaning performance.

#21: HoMedic AR-20 Air Purifier

The Homedic AR-20 Air filtration system provides HEPA filtration. It costs 72 cents per square foot of air cleaned per year. It covers 160 square feet and has an MSRP value of $129.99. It costs $1154.45 to use for 10 years. This purifier is designed to reduce particle pollution in the air. It has a poor cost-value benefit compared to the systems that made Top Ten rankings. The draw of this system is that it has a low front end investment.

#20: 3M Filtrete FAP03 Air Purifier

The Filtrete FAP03 purifier costs 71 cents per square foot of air cleaned per year. It provides HEPA filtration. That is what it is designed for and that is what it does. It has an MSRP of $199.99. It covers 350 square feet. It costs $2494.75 to use this filter for 10 years. The company backs this air purifier with a one year warranty. Choose it for particle filtration but do not expect it solve complex air quality problems.

#23: GE AFHC 32AM Air Purifier

The GE AFHC 32AM Air Purifier scrapes into the top 25 at #23. It costs 85 cents per square foot of air cleaned per year. It has an MSRP value of $899.98 and covers 500 square feet. It costs $4257.40 to use this purifier for 10 years. It comes with both a carbon and HEPA filter but as with most of these systems in the bottom 15, the carbon filtration isn't worth much. The company backs this air purifier with a one year warranty. If you can afford to, look at purifiers a little further up the ladder.

#22 Haier HAPE300 Air Purifier

The Haier HAPE 300 Air Purifier uses a HEPA filter to remove particles from the air. It has a carbon filter too, but do not expect much in the way of odor and gas filtration from it. It costs 77 cents per square foot of air cleaned per year. It covers 264 square feet of air. It costs $2033.90 to use this air purifier for 10 years. The company backs this air purifier with a 5 year warranty on parts and a one year warranty on labor.

#25 FilterQueen Defender

The FilterQueen Defender comes in at #25. It costs $1.44 per square foot of air cleaned per year. It has both carbon and hepa filtration. Only the hepa filtration in this system should be considered efficient. This air purifier has an MSRP of $850 and covers 300 square feet. It costs $4312.32 to use over 10 years. The company backs this purifier with a 2 year warranty. The cost-benefit value is poor. This purifier is not even cheap on the front end so I recommend looking at the top Ten systems.

#24: Amway Atmosphere Air Purifier

The Amway Atmosphere Air Purifier comes in at #24 because it costs $1.44 per square foot of air cleaned per year. It actually has better filtration than most of the bottom 15. It provides both hefty particle (HEPA) and carbon (odor and gas) filtration. It covers 390 square feet and has an MSRP value of $1075.00. It costs $5610.02 to use for 10 years. It has a 2 year warranty. Amway set out to make one of the most efficient particle filtration systems. But they charge so much in the way of costs for the machine and filters that the cost-benefit value of this system became very poor. Just compare it to the top Ten systems if you have any doubts.

Research Air Purifiers

The Top Ten systems represent the best air purifiers in the world from the top companies. Numbers 11-25 feature the very best air purifiers from competing companies. Each number features the very best purifier from its particular company. As you can see, many companies have gotten away for far too long with substandard product performance because consumers are uneducated about air quality. Be sure to do your research before buying an air purifier. I also recommend that you consider the type of systems featured in the top ten because they are designed to solve real indoor air quality problems.
