What is HEPA lter?
Acronym for High Ef ciency Particulate Air, HEPA lter is a very common and effective mechanical air
lter found in most modern air puri ers. Made from thin interlaced bers, HEPA lter can eliminate
harmful particles as small as 0.3 microns at an effective rate of 99.97%. The best HEPA air puri er
brand such as IQAir, Blueair could go even further by removing the tiniest possible airborne particles
that cannot be captured by standard lter.

Pre- lter Almost all air puri er comes with Pre- lter. Period. Commonly act as a stand-alone
permanent lter, the pre- lter will serve 2 key roles here: One is to lter out airborne particles
predominantly hair and dust. Second is to shield the HEPA lter from large particles and ensure there
is no obstruction that could affect the ltration ef ciency. Regardless if is a permanent or carbon-
based combination lter, if the pre- lter can do as it supposes to do, then it passed our rst criteria.


HEPA lter With pre- lter focused on large airborne particles, HEPA lter 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 puri er must
come with a quality, genuine True HEPA lter. No inferior, aftermarket solution. Only then we will
measure the lter best possible ltration rate against all household allergens and contagious viruses
when called upon.


Room size/ Coverage According to reports, an average houses size in U.S. has a size of 2,687 square
feet. A pretty sizable number that only a whole house air puri er can cover. In this best HEPA air
puri er 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 air ow
delivery rate and applicable radius is a critical measurement. Also, we do take the air puri er size and
price into consideration as each unit would cater to 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 bene t 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 ghting 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 HEPA air puri er for one reason: It produces THE best lter in the world. With
improved ltration rate at every generation, HyperHEPA Filter can eliminate the tiniest, microscopic
particles as small as 0.003 micron size. Remarkable given standard HEPA lter can only trap particles
at best 0.3 microns. Other bene cial features include an advanced PreMax pre- lter to tackle on
larger airborne particles, wide purifying coverage that support any room size and abundant of air ow
delivery rate via its highly adjustable 6 speed.
Even though all IQAir HealthPro air puri er utilizes the same HyperHEPA lter, the Plus model is the
bulkiness due to the added V5-Cell Gas & Odor Filter MG carbon lter slot. Another niggling point is
the lacks Auto mode and AQ sensor; both features available in most air puri er listed here. If you can
live with the few cons plus the premium price, IQAir HealthPro Plus should always be in your bucket
list.

Made in Switzerland craftsmanship with strong impact resistant ABS plastic and zero-leak triple-
seal technology.
PreMax pre- lter that is capable of capturing both large and micro-particles such as pollen, spores,
mold.
Effective V5-Cell MG Granular activated Carbon lter that absorb and eradicate all types smoke

down to 0.003 microns.
Long-lasting lter. True HEPA lter has 4 years lifespan, Carbon lter has 2 years lifespan and even
pre- lter has a 18 months lifespan.
Certi ed quality and performance. Each air puri er are individually tested to ensure the air puri er
meets the strict speci cations.

Blueair Classic 500/600 Series Particle Filter


Coverage
775 sq. ft. (72 m )
Blueair has one of the most complete series air puri ers 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, air ow and purifying coverage. Let’s start with the basic, Blueair
605 standard particle lter is very effective against allergies causing mold and pollen as small as 0.1
microns. The HEPASilent technology is capable of achieving maximum ltration ef ciency due to the
pre- lter and ionizer combined effort in removing large airborne particles. Adding the wide purifying
range that ts into most home, this highly reputable HEPA machine is a good alternative to IQAir
HealthPro Plus without sacri cing any of the modern practicality (i.e. Auto mode, air quality display).
Same air puri er buying rules applied to Blueair models, the more powerful the air puri er is, the
costlier and bulkier it will be. No exception with the gigantic Blueair Classic 605. If you want a more
space-ef cient unit without giving up on the Wi-Fi connectivity feature, you could downgrade to
either Blueair 405 or 205.
Widest purifying coverage and strongest air ow in its Classic series.
HEPASilent Technology that electrostatically charge particles before passing to lter media.
Highly effective gradient structured particle lter and SmokeStop Filter.
Very impressive dust, pollen and smoke CADR return.
Top-notch build quality with its durable galvanized steel body.
Wi-Fi connects easily and works well with the intuitive Blueair Friend app or Amazon Alexa.
Up to 5 years warranty.
The most expensive model in Blueair Classic series.
Very high annual lter replacement cost.
Lacks stand-alone pre- lter that would capture large particles from other lters.
Lacks integrated air sensors for air quality monitoring and Auto mode. Requires the addon
purchase Blueair Aware monitor to enable the feature.
Bulky and heavy although we expect no less.

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 ltration, we decided to keep this best HEPA air puri er list in
balance by going with Winix 5500-2; The cheaper but still equipped with an equally effective True
HEPA lter. The main reason for Winix 5500-2 inclusion is the air puri er manage to perform
2


exceptionally well thanks to the permanent pre- lter that take out all large particles upfront. Winix
5500-2 supportive air ow (with auto mode) and wide purifying coverage also allow the air puri er 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 puri ers but in the end, there is a trade-off with either poorer air ow performance or
features. Alternatively, the older Winix U450 is also a good alternative which we also highly
recommend.
Super attractive price (after online rebate) when you consider the complete speci cation offering.
Decent CADR that covers medium room size well via its 4-stage ltration and PlasmaWave
technology.
Washable pre- lter that might be a hassle to maintain, you will be glad how much money and dust
you have collected even a short period of time.
Genuine, True-HEPA lter works as advertised in removing allergens and other germs
microorganisms.
Use a standalone AOC carbon lter rather than cheap out on a carbon pre- lter sheet.
Full access remote control including the mode selector.
4 fan speed plus Auto mode and Sleep mode. Sleep mode pairs well with the light sensor that
autonomously adjusts the LED indicator brightness according to the room ambient light.
Built-in timer with 3 pre-set option (1, 4, 8 hours).
Not outstanding, but an improved 2 years warranty (Winix 5500 only comes with 1-year warranty).
We like the dedicated AOC carbon lter, but it's not the best in the market when it comes to strong,
pungent smell.
During our test, there is a delay (2-4 minutes) before the air puri er reacts to surrounding airborne
particles. Either the odor sensor requires cleaning or the sensor takes its own sweet time to detect.

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 puri er. It has a comprehensive
purifying radius (815 square feet to be exact), a reliable HEPA lter (0.3 microns/ 99.97% ltration
rate), and many supportive lters (pre- lter, medium lter, carbon lter). In addition, there are 4
available options for the customized lter where you could select from Germ Defense, Toxin Absorber,
Pet Allergy, Odor Remover. This is no doubt the most complete, air puri er for asthma and allergies.



Like IQAir or Bluair, Rabbit MinusA2 is on the expensive side even though annual lter replacement is
relatively cheap. If you need a basic air puri er without all the addons and mumbo jumbo, consider the
more cost-effective Rabbit Air BioGS 2.0.
Full depth 6-stage ltration with improved air ow performance and coverage.
Low lter replacement cost despite having many added lters.
Beautiful, square design with mood light color bar.
Wall-mountable with plenty of customized front panel design to choose from (optional purchase).
Effective First line ltration (Pre- lter, Medium and HEPA lter).
4 Customizable lter options, AC carbon lter and Negative Ion Generator (Ionizer) for extra
ltration.
5 fanspeed with Auto/ Pollen/ Sleep mode.
Separate Particle, odor and light sensor. Particle/ air quality sensors sensitivity can be adjusted.
Sensitive Sleep mode that activates and adjust the air puri er speed automatically when light is
out.
Five-year warranty with free return.
All the added features helped push the price up to premium category.
For the price you paid, there are better alternate options solely on purifying coverage, CADR and
air ow delivery rate.
Far from light despite being a wall-mountable unit with back wall-bracket.

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 puri er without getting penalized on its air ow delivery
performance. What's great with Austin Air HealthMate air puri er is it has the exact same extensive
purifying coverage in any models, plus the same trio "pre- lter" that lter out as many airborne
particles as possible leaving the 60 sq. ft. HEPA lter space to work its magic. The all-in-one cartridge
which consists of a HEPA lter 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 puri ers.
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.
Great for all room sizes with its comprehensive purifying coverage.
Trio pre- lter (outer mesh, pre- lter, medium lter) that reduce the workload of the HEPA lter.
Highly effective 15 lbs. Activated carbon zeolite lter.
Comprehensive 60 sq. ft. HEPA lter.
Durable and sturdy powdered coated steel.
Up to 5 years lter lifespan.
5 years manufacturer warranty.
Loud fan noise with no option of silent/ sleep mode.
Very bulky and heavy despite having a casters to support.
Hassle lter replacement that requires lter to be unscrew from the bottom.
Slight innovative features such as auto mode, digital screen, air quality indicator,/ sensor, timer.

Honeywell has the most air puri er 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 HEPA air puri er for home. It cost the least, has a smaller body con guration yet without
compromising too much on air ow 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 rst line carbon pre- lter while smaller microscopic allergens will then be eliminated
by the well-protected HEPA lter. With many Honeywell models shipped worldwide, there is no doubt
HPA300 air puri er proven track record and reliability are the real deal.
Like Austin Air, Honeywell HPA300 HEPA air puri er 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.
Very reasonable price with exceptional purifying coverage and CADR.
Adjustable 4 fan speed including Turbo mode.
Dual combination Carbon Pre- lter that is good against dust and mild gas based particles.
Proven True-HEPA lter that is very effective against ne airborne particles.
Separate electronic lter change reminder with one for HEPA lter and the other one for carbon

Dedicated light dimming option and 3 pre-set timer that is suitable for night use.

Coverage
1256 sq. ft. (117 m )
Between all the other Airmega models, Airmega 300 gets the nod here as it has the cheapest starting
price. Unlike every other air puri er listed here that uses 1 pre- lter as part of the puri cation,
Airmega 300 uses 2 pre- lter on both sides to evenly lter out large particles coming from left and
right. As a result, Green True HEPA lter has the easiest task in trapping microscopic allergens, germs,
and bacteria. There is also the very wide purifying coverage dedicated large room size, consistent
air ow circulation to compliment well on Airmega 300 overall ltration along with a wholesome of
features which you can see in the speci cation below.
What's powering current Airmega air puri er lineup is the same Max2 ltration set (dual pre- lter +
Green True HEPA lter), 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 ltration performance with the
same set of features.



4-stage ltration with wide purifying coverage despite being the least expensive model.
Dual pre- lter that traps large particles from both sides while protecting the HEPA lter and
Carbon lter.
Excellent allergens and smoke ltration via its Green True HEPA lter and Activated Carbon lter.
Auto mode that is sensitive to set the right speed based on surrounding air quality.

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

Additional Information
 How to choose the best HEPA air puri er.
"The old cliché" choose your partner wisely applies to the air puri er world. Once you made an air
puri er yours, very likely the purifying machine will be stuck with you for a very long time. Choosing
an air puri er with proven True HEPA lter can be the difference between day and night. Also consider
factors like the overall dimension, air ow performance, purifying range, and cost of ownership that
would directly or indirectly affect the air cleaner ef ciency.
9 Tips for Choosing the best HEPA Air Puri er
1. Cost of ownership - There is a lot of reputable air puri ers that is below the $200 mark however,
its the annual lter replacement is going to kill you. Consider the lter lifespan for long-run.
2. Size and weight - Generally only console air puri er can accommodate a full-size HEPA lter
which translate to better overall ltration ef ciency. There are few exceptional models though.
3. CADR/ Airflow performance - This one is a no brainer. With higher air ow/ CADR output, more
airborne particles will be pushed to the lter to capture at every go.
4. Room size - First measure the room size where you decided to place the air puri er. Then cross-
check if the particular model will be able to ful ll that with a minimum of 2 air charges of air ow.
5. HEPA filter - Arguably the most important factor here. Always go with True HEPA lter that has at
least 99.97% ef ciency rate on particles as small as 0.3 microns. Permanent lter or HEPA-type
lter simply won't cut it.
6. Other filters (Pre-filter, Carbon filter, Ionizer...) - HEPA lter alone cannot handle the many types
of airborne pollutants. You will need a Pre- lter to block out dust/ hair, a Carbon lter 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 puri er a complete bliss.
8. Power consumption and noise level - Having an energy-ef ciency 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 lter based air puri er 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.
