Best HEPA Air Purifier for Home

2019 Best Home Air Purifiers with HEPA Filter

An air purifier is not an air purifier without a HEPA filter. Strong words, even though it does hold some point to it. In this best home air purifier list, we will learn about the many types of HEPA filter, why is it important, what can the filter stop and who is it for. To qualify in this list, each HEPA air purifiers must include a reliable pre-filter, followed by a genuine HEPA filter. Lastly, the HEPA machine must be able to cater for most home with sufficient airflow output and purifying coverage. At the end of the day, there is bound to be at least one HEPA air cleaner that would suit your needs.

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 can eliminate harmful particles as small as 0.3 microns at an effective rate of 99.97%. The best HEPA air purifier brand such as IQAir, Blueair could go even further by removing the tiniest possible airborne particles that cannot be captured by standard filter.

How do we measure?
Pre-filter Almost all air purifier comes with Pre-filter. Period. Commonly act as a stand-alone permanent filter, the pre-filter will serve 2 key roles here: One is to filter out airborne particles predominantly hair and dust. Second is to shield the HEPA filter from large particles and ensure there is no obstruction that could affect the filtration efficiency. Regardless if is a permanent or carbon-based combination filter, if the pre-filter can do as it supposes to do, then it passed our first criteria.
HEPA filter With pre-filter focused on large airborne particles, HEPA filter would serve a bigger role here by trapping micron size particles that cannot be seen via our naked eyes. This includes allergens, germs, and bacteria that regularly spread through the air. First and foremost, the air purifier must come with a quality, genuine True HEPA filter. No inferior, aftermarket solution. Only then we will measure the filter best possible filtration rate against all household allergens and contagious viruses when called upon.
Room size/ Coverage According to reports, the size of an average house in U.S. has a size of 2,687 square feet. A pretty sizable number that only a whole-house air purifier can cover. In this best home air purifier list though, our test unit does not have to fully cover the entire house at one go, but it should provide decent to excellent purifying coverage on a room-to-room basis. This means the airflow delivery rate and applicable radius is a critical measurement. Also, we do take the air purifier size and price into consideration as each unit would cater to a 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 cleaner air. Young and old that tend to have weakened immune system especially baby and children. A person staying in high moisture home that is constantly fighting against mold. A person staying in a bad environment neighborhood such as industrial area or next to a highway, lastly and surprisingly to most, staying close to nature/ countryside with windows wide open to seasonally inviting pollen from invasion.

While you can't go wrong with any of IQAir HealthPro models, we picked IQAir HealthPro Plus as our number one best home air purifier for one reason: It produces THE best filter in the world. With improved filtration rate at every generation, HyperHEPA Filter can eliminate the tiniest, microscopic particles as small as 0.003 micron size. Remarkable given standard HEPA filter can only trap particles at best 0.3 microns. Other beneficial features include an advanced PreMax pre-filter to tackle on larger airborne particles, wide purifying coverage that support any room size and abundant of airflow delivery rate via its highly adjustable 6 speed.

Even though all IQAir HealthPro air purifier utilizes the same HyperHEPA filter, the Plus model is the bulkiness due to the added V5-Cell Gas & Odor Filter MG carbon filter slot. Another niggling point is the lacks Auto mode and AQ sensor; both features available in most air purifier listed here. If you can live with the few cons plus the premium price, IQAir HealthPro Plus should always be in your bucket list.

Blueair has one of the most complete series air purifiers that cover small "studio" to large "mansion" room size (see Blueair Pro XL purifying coverage). We picked this over other classic range models as it's better balanced between price, airflow and purifying coverage. Let’s start with the basic, Blueair 605 standard particle filter is very effective against allergies causing mold and pollen as small as 0.1 microns. The HEPASilent technology is capable of achieving maximum filtration efficiency due to the pre-filter and ionizer combined effort in removing large airborne particles. Adding the wide purifying range that fits into most home, this highly reputable HEPA machine is a good alternative to IQAir HealthPro Plus without sacrificing any of the modern practicality (i.e. Auto mode, air quality display).

Same air purifier buying rules applied to Blueair models, the more powerful the air purifier is, the costlier and bulkier it will be. No exception with the gigantic Blueair Classic 605. If you want a more space-efficient unit without giving up on the Wi-Fi connectivity feature, 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. Rather than recommend Winix HR1000 that has all the modern techs including Wi-Fi support and a comprehensive 5-stage filtration, we decided to keep this HEPA air purifier list in balance by going with Winix 5500-2; The cheaper but still equipped with an equally effective True HEPA filter. The main reason for Winix 5500-2 inclusion is the air purifier manage to perform exceptionally well thanks to the permanent pre-filter that take out all large particles upfront. Winix 5500-2 supportive airflow (with auto mode) and wide purifying coverage also allow the air purifier to cover medium to large room size including living hall

Winix 5500-2 is not the smallest in the class, nor it is the cheapest. You could go with many other cheaper air purifiers but in the end, there is a trade-off with either poorer airflow performance or features. Alternatively, the older Winix U450 is also a good alternative which we also highly recommend.

Put aside the changeable front panel and mood light aesthetic enhancement, there are a lot of solid reasons to pick Rabbit Air MinusA2 SPA-780A as your daily air purifier. It has a comprehensive purifying radius (815 square feet to be exact), a reliable HEPA filter (0.3 microns/ 99.97% filtration rate), and many supportive filters (pre-filter, medium filter, carbon filter). In addition, there are 4 available options for the customized filter where you could select from Germ Defense, Toxin Absorber, Pet Allergy, Odor Remover. This is no doubt the most complete, air purifier for asthma and allergies.

Like IQAir or Bluair, Rabbit MinusA2 is on the expensive side even though annual filter replacement is relatively cheap. If you need a basic air purifier without all the addons and mumbo jumbo, consider the more cost-effective Rabbit Air BioGS 2.0.

Austin Air probably has the most identical lineup in terms of exterior design. We choose the standard HealthMate as it is the least expensive 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 many airborne particles as possible leaving the 60 sq. ft. HEPA filter space to work its magic. The all-in-one cartridge which consists of a HEPA filter has an outstanding lifespan up to 5 years; the best in this list by a far margin.

What's lacking in Austin Air functionality can be found in almost any modern day air purifiers. Features like air quality sensors, Auto mode, timer, and so much more are all not available here. Not a big deal for some but is the things you should be informed up front. There is also a Jr version for most of its lineup that cut down on size and price for the trade-off for a smaller purifying coverage.

Honeywell has the most air purifier currently listed in its stable where the majority of its model is aimed at low to mid-range market. No surprise as once again, we listed Honeywell HPA300 as part of our best air purifier for home. It cost the least, has a smaller body configuration yet without compromising too much on airflow performance. The strong CADR help push Honeywell HPA300 purifying coverage up high cater for medium to large room size. Managing all the airborne dust, smoke and odors is the first line carbon pre-filter while smaller microscopic allergens will then be eliminated by the well-protected HEPA filter. With many Honeywell models shipped worldwide, there is no doubt HPA300 air purifier proven track record and reliability are the real deal.

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

Between all the other Airmega models, Airmega 300 gets the nod here as it has the cheapest starting price. Unlike every other air purifier listed here that uses 1 pre-filter as part of the purification, Airmega 300 uses 2 pre-filter on both sides to evenly filter out large particles coming from left and right. As a result, Green True HEPA filter has the easiest task in trapping microscopic allergens, germs, and bacteria. There is also the very wide purifying coverage dedicated large room size, consistent airflow circulation to compliment well on Airmega 300 overall filtration along with a wholesome of features which you can see in the specification below.

What's powering current Airmega air purifier lineup is the same Max2 filtration set (dual pre-filter + Green True HEPA filter), so in theory, Airmega 300 is probably not the best value in its bunch as the slightly more expensive S version comes with Wi-Fi control support for remote access. Again top up a little bit further, you could have the 400 version that offers superior filtration performance with the same set of features.

Additional Information

HEPA Type VS True HEPA filter: What's the Difference?

The major differences between HEPA Type VS True HEPA filter are the filtration efficiency. In general HEPA type filter has a 99% efficiency capture rate of particles as small as 2 microns (dust, hair, pet dander, pollen). True HEPA filter up the game with a better 99.97% efficiency capture rate of particles as small as 0.3 microns (allergen, bacteria, virus). As both mechanical filters are widely used in the air purifier industry, HEPA-type filter is often pair with cheaper, compact air purifier while True HEPA is more than likely tag with the bigger, premium air purifier. As for filter longevity, you will often find HEPA type filter with a longer lasting, or permanent lifespan (washable) while it’s almost impossible to associate it with True HEPA filter. Both types of filters can trap virtually any indoor airborne particles however, if seasonal allergens and bacteria is your main concern, an air purifier with True HEPA filter is the one to go for.

How To Choose The Best Home Air Purifier

"The old cliché" choose your partner wisely applies to the air purifier world. Once you made an air purifier yours, very likely the purifying machine will be stuck with you for a very long time. Choosing an air purifier with proven True HEPA filter can be the difference between day and night. Also consider factors like the overall dimension, airflow performance, purifying range, and cost of ownership that would directly or indirectly affect the air cleaner efficiency.

  1. Cost of ownership - There is a lot of reputable air purifiers that is below the $200 mark however, its the annual filter replacement is going to kill you. Consider the filter lifespan for long-run.
  2. Size and weight - Generally only console air purifier can accommodate a full-size HEPA filter which translate to better overall filtration efficiency. There are few exceptional models though.
  3. CADR/ Airflow performance - This one is a no brainer. With higher airflow/ CADR output, more airborne particles will be pushed to the filter to capture at every go.
  4. Room size - First measure the room size where you decided to place the air purifier. Then cross-check if the particular model will be able to fulfill that with a minimum of 2 air charges of airflow.
  5. HEPA filter - Arguably the most important factor here. Always go with True HEPA filter that has at least 99.97% efficiency rate on particles as small as 0.3 microns. Permanent filter or HEPA-type filter simply won't cut it.
  6. Other filters (Pre-filter, Carbon filter, Ionizer...) - HEPA filter alone cannot handle the many types of airborne pollutants. You will need a Pre-filter to block out dust/ hair, a Carbon filter to remove smoke/ odor, Ionizer to break apart stubborn particles and the list goes on and on.
  7. Supportive features (Auto/ Sleep mode, timer) - Having convenience yet practical features like Auto mode, Sleep mode or timer would make operating an air purifier a complete bliss.
  8. Power consumption and noise level - Having an energy-efficiency unit with reasonable noise level can determine how liveable the air cleaner is as users will likely run it all day every day.
  9. Branding reputation - A filter based air purifier don't break down very often as is not a sophisticated technology. Choosing a reputable brand not only guarantees better after-sale services and warranty claim, you are also getting an assuring purifying technology that the company has invested hundreds on research and testing.
