In this best HEPA air purifier for home list, we will understand more about HEPA filter, why is it effective, what can it do and who is this for. To qualified into the list, each air purifiers must passed the first criteria which include a pre-filter whether as a stand-alone or a combination filter, second a genuine HEPA filter/ layer that is effective against allergen, bacteria and viruses and lastly able to catered for most home with sufficient airflow and purifying coverage. At the end of the day, there will be at least one HEPA air purifier that would suit you according to your needs and home.

What is HEPA filter?

Acronym for High Efficiency Particulate Air, HEPA filter is a very common and effective mechanical air filter found in most modern air purifiers. Made from thin interlaced fibers, HEPA filter has an efficient rate of 99.97% against airborne particles that cannot be capture by standard filter. Most HEPA filter in the market can eliminate harmful particles as small as 0.3 microns e.g. pollen, bacteria and viruses while premium brand such as IQAir, Blueair could go further by handling even the tiniest possible particles.

How do we measure?

Pre-filter Pre-filter will serve 2 purpose here. One is to filter out airborne particles predominantly dust, second is to shield the HEPA filter from large particles so the filter would have an optimal filtration rate. Regardless it is a standalone or combination set filter, if the pre-filter can achieve the 2 criteria then is fine with us.
HEPA filter With pre-filter focused on large airborne particles, HEPA would serve a bigger role here by trapping micron size particles that cannot be seen via our naked eyes. This includes allergens, germs, bacteria and viruses that regularly spread through the air. What we want from the HEPA filter is have the best possible filtration rate against all household allergens, mold, pollen or contagious viruses when called upon.
Room size/ Coverage According to reports, U.S. alone have an average houses size of 2,687 square feet. While the air purifier tested here does not have to fully cover the entire house at one go, it should provide decent to excellent purifying coverage on room-to-room basis. We would also take the air purifier size and price as into the consideration factor as each air purifiers would catered for different market niche.

Who is this for?

Virtually anyone that wants fresh clean air free from allergens, bacteria and viruses. Asthmatic patient or people with hyperallergic would benefit greatly from a cleaner air. Young and old that tend to have weak immune system specially baby and children. Person staying in high moisture home that is constantly fighting against mold. Person staying in a bad environment neighborhood such as industrial area or next to highway, lastly and surprisingly to most, staying close to nature/ countryside with windows wide open therefore seasonally inviting pollen from invasion.

While you can't go wrong with any of IQAir HealthPro models, we picked IQAir HealthPro Plus as our ideal HEPA home air purifier because it has one of the best filtration carbon filter . All IQAir HealthPro models utilize the same HyperHEPA Filter that handle the tiniest size particles as small as 0.003 micron size. Remarkable given standard HEPA filter can only trap particles at best 0.3 microns. Other beneficially features include a wide purifying coverage that would cover any room size plus abundant of airflow delivery rate via its highly adjustable 6 speed.

Bulky, heavy, lacks Auto mode and AQ sensor is always the niggling points of HealthPro air purifier. If you can live with that plus the price bump for the carbon filter, IQAir HealthPro Plus should always be in your bucket list.

Blueair has one of the most complete series air purifier that covers small "studio" room size to large "mansion" room size (see Blueair Pro XL purifying coverage). We picked the best in its classic range as its better balanced between price, airflow and purifying coverage. First off Blueair 605 standard particle filter is very effective against allergens, mold and pollen as small as 0.1 microns. The HEPASilent technology is able to achieve maximum filtration efficiency due to pre-filter and ionizer combined effort in filtering out large and tricky airborne particles. Adding the wide purifying coverage that would cater for most home, this highly reputable HEPA machine is a good alternative to IQAir HealthPro Plus.

Same air purifier buying rules applied to Blueair models, the more powerful the unit is the costlier and bulkier it will be. No exception with the bulky Blueair Classic 605. If you want a space-efficient unit, you could downgrade to either Blueair 405 or 205.

Winix brand also have a diverse portfolio ranging from the entry-level Winix 5300-2 to advanced Winix T1. We recommend Winix HR1000 as it has all the modern techs including Wi-Fi support and a comprehensive 5-stage filtration to help ease the burden of HEPA filter. The True HEPA filter manage to perform exceptionally well thanks to its permanent pre-filter that take out all large particles upfront. The antimicrobial coat would protect the HEPA filter from microorganisms growth thus prevent any performance reduction efficiency. Winix HR1000 wide purifying coverage would also covers large room size including living hall and lounge.

Its not the smallest in the class, again similar approach with Blueair, you could go with the slightly cheaper Winix HR950 if you do not need the Wi-Fi support, Winix 5500-2 for smaller purifying coverage or Winix U450 which we also highly recommend.

All 3 BreatheSmart models is a good candidate for best home HEPA air purifier. We picked the mid child Alen BreatheSmart Fit50 as it strike balanced between price and performance. The default HEPA-Pure filter is more than capable of tackling household contaminants and allergens, you do have the option to upgrade your filter in one of the selectable 3 that would better manage microorganism and odor troubles. With or without the filter upgrade, Alen BreatheSmart Fit50 has an excellent supporting cast in the form of pre-filter and ionizer that further enhanced the filter lifespan and usability. Further complimenting with its sufficient purifying coverage for most home, Alen BreatheSmart Fit50 would be a great alternative to Winix brand.

As mentioned earlier, you could either opt for the original Alen BreatheSmart with higher purifying radius that obviously cost more or the least expensive and smallest Alen BreatheSmart Flex. Neither of the 3 models has a dedicated carbon filter but that would never hinder it as a great HEPA air purifier.

Austin Air probably has the most identical lineup in terms of exterior design. We choose the standard HealthMate as it is the least expensive HEPA air purifier without getting penalized on its airflow  delivery performance. What's great with Austin Air HealthMate air purifier is it has the exact same extensive purifying coverage in any models, plus the same trio "pre-filter" that  filter out as much airborne particles as possible so the 60 sq. ft. HEPA filter would have space to work its magic. Because of the filters combined effort, the cartridge which consist of HEPA filter has an outstanding filter lifespan up to 5 years; the best in this list by a far margin.

What's lacking in Austin Air purifier is almost any modern features available elsewhere including air quality sensors, Auto mode, timer and more... Not a great deal for some but is at least the things you should be aware. There is also a Jr version for most of its lineup that cut down on size and price trading off for a smaller house.

Honeywell has the most air purifiers within in stable that majority is aimed at low to mid-range. No surprise as again we listed Honeywell HPA300 as one of our best HEPA air purifier for home. It cost less, has a smaller body without compromising too much on airflow performance. The strong CADR help push Honeywell HPA300 purifying coverage up high that can cater for most home. Managing airborne dust, allergens and odors is the first line carbon pre-filter while protecting the effectiveness of HEPA filter from large particles. With many Honeywell models shipped worldwide, Honeywell HEPA filter track record and proven reliability is the real deal.

Like Austin Air, Honeywell HPA300 is plain on features but understandably so due to the price and size factor. For smaller home or room sizes, you could downsize to the cheaper Honeywell HPA200 or even cheaper HPA100.
