7 Best Honeywell Air Purifiers In 2021: Compared, Reviewed, Rated

“Just give me a standard reliable no-nonsense air purifier.”

If you walk up to Home Depot and say the above to the customer service, they will most probably show you Honeywell air purifiers.

Honeywell, in general, makes all kinds of HVAC devices. Their air purifiers are considered very reliable. On top of that, Honeywell air purifiers have solid specs and an affordable price.

Example: The latest and best Honeywell air purifier –  the Honeywell HPA300 – has a 320 dust CADR rating. Even more impressive is the price; you can get HPA300 – a 320 CADR rating air purifier – for less than $250.

Of course, Honeywell air purifiers can’t possibly compare to the superior Alen BreatheSmart air purifiers.

There are few reasons why buying the no-nonsense standard Honeywell air purifiers makes sense:

  1. All of them use True HEPA filters. Standard tech, certified.
    removing dust, pollen, bacteria, viruses from indoor air to increase air quality
    Honeywell True HEPA filter is especially good at removing various-size allergens from indoor air.
  2. They don’t include the expensive fancy new tech like Molekule or Airdog $600+ models.
  3. All of them have earned the AHAM Verifide badges; some even have the Energy Star certificate for superb energy-efficiency.
  4. They are fairly cheap and have good price-performance.

In short, Honeywell is pretty much the biggest overall company that makes air purifiers. They are big for a reason:

Honeywell has been in business for 114 years (since 1906).  Their air purifiers are tried-and-tested reliable devices with True HEPA filters and available at low prices.

With a lot of reliable models, LearnMetrics has chosen the 7 very best Honeywell air purifiers. The spec-by-spec analysis shows how well these units perform to remove dust, pollen, smoke, mold, dander, and other air pollutants, thereby elevating indoor air quality.

Honeywell Filtration System With HEPA Filters

There is nothing extraordinary about Honeywell filters. That’s exactly the point; they are no-nonsense filters, actually made by Honeywell.

All Honeywell air purifiers use the basic 2-stage filtration system, comprised of:

  1. Honeywell A and A+ pre-filters. Capture large particles like lint, pet fur, and larger dust particles. Pre-filter should be regularly cleaned and replaced every 3 months.
  2. True HEPA R filters for small particles. Designed to capture up to 99.97% of microscopic allergens, dust particles, pollen, smoke, and other particles that are 0.3 microns in diameter or larger. It should be replaced every 12 months.

Both filters are certified and sold by Honeywell.

Honeywell’s Certified HEPA filters work very well at removing even the smallest air pollutants.

What really lacks compared to other standard low-price filtration systems Hathaspace and Okaysou, even Levoit uses, is the activated carbon filter. Activated carbon filter adsorbs VOCs such as kitchen odors or cigarette smell.

Honeywell doesn’t use a specialized activated carbon filter. Rather, they have a pre-filter that doubles as an activated carbon filter. It’s important to note that CADR rating (be it dust, pollen, or smoke) doesn’t measure the effectiveness of an air purifier to remove odors.

It’s not hard to see that Honeywell air purifiers don’t work well for removing undesired odors or smells. The lack of a dedicated activated carbon filter is concerning, but you have 1 fewer filters to replace every 6-12 months.

Honeywell air purifiers with the 2-stage filtration system do work well against allergens, however. Honeywell claims that Honeywell HEPA air purifiers are ‘The Doctor’s Choice’ and the ‘#1 brand recommended by allergists.’.

The HEPA filters undoubtedly work very well at removing allergens and dust particles that may have an effect on asthma, for example.

Coverage Area (Based On CADR Rating And ACH)

Honeywell True HEPA air purifiers are very effective at removing air pollutants from Honeywell’s recommended coverage areas. That’s because the room size – ranging from 150 sq ft to 500 sq ft – is calculated based on 5 air changes per hour.

Example: The best large room air purifier Honeywell HPA300 can work through all the air in 465 sq ft 5 times per hour. Essentially, it completely replaces air within a room of such dimensions every 12 minutes.

That’s only possible because of the high purification performance, expressed by the CADR rating. The CADR rating is the most important specification for all air purifiers. Honeywell’s top HPA air purifiers, for example, are named based on CADR rating:

For all these coverage areas and CADR ratings, Honeywell has a certificate. These specifications were verified by AHAM; this is a voluntary certification, and big companies such as Honeywell are smart to take it.

AHAM Verifide certificate for Honeywell HPA300.

In short, you can trust the Honeywell specification sheets to the point.

Honeywell Air Purifier Special Features

Honeywell doesn’t put all that many special features in the air purifiers. First of all, they don’t really add that much value, and secondly, this helps keep the price of all Honeywell air purifiers below $300.

The essential thing is the easy-to-understand control panel you can see here:

No-nonsense control panel on Honeywell HPA Series air purifiers.

You can see the useful Auto-Off timers; you can set it to 2h, 4h, or 8h.

All the best Honeywell air purifiers also have the filter replacement indicator. You can see the HEPA filter indicator (‘CHECK FILTER’) and pre-filter (‘CHECK PRE-FILTER’) above.

You can also have 4 cleaning levels; for allergen removal, general air cleaning, and against germs. On top of that, you have the turbo setting (with HPA Series air purifiers) that puts the Honeywell air purifier at the highest gear.

The last feature is ‘DIMMER’. If you want to place a Honeywell air purifier in the bedroom during the night, you can reduce or fully eliminate all the lights coming from the unit.

With all this in mind, let’s look at the best rated Honeywell HEPA air purifiers:


1. Honeywell HPA300 Review (Overall Best Honeywell Air Purifier)

Overall Best Honeywell Air Purifier
Coverage Area: 465 sq ft
CADR Rating: 320 Dust, 300
Filters: Pre-filter, True HEPA
Filter Lifespan: 12 (HEPA) and 3 (Prefilter) months
Fan Speeds: 3 + Turbo Clean
Dimensions: 9.3 x 20 x 22.2 inches
Weight: 21 lbs
Price: $$$$
Rating: 4.9 out of 5 stars

The HPA is Honeywell’s main and best air purifier series. In this list of the best air purifier made by Honeywell, you will find the HPA100 and HPA200. However, both of these units were just a stepping stone to the overall best Honeywell air purifier – the HPA300.

HPA300 is the large room air purifier with an AHAM verified 465 sq ft coverage area; that’s a 21×22 room, for example. On top of that, it’s one of the few air purifiers with an Energy Star rating.

It’s the most powerful high-performance air purifier, with an immense 300 CADR rating. Its smoke CADR rating is even higher – 320. This has almost placed it on our list of the best air purifiers for smoke.

The Honeywell HPA300 is the very ‘standard, reliable, no-nonsense’ air purifier that most Honeywell buyers want. You get the True HEPA filter that needs to be replaced once a year, and the odor-reducing pre-filter HRF-AP1 needs to be replaced every 3 months.

That’s it; a capable and low maintenance Honeywell HPA300 air purifier is the best Honeywell has to offer. It also has a budget-friendly price tag; the 300 CADR rating air cleaner costs less than $300:

Honeywell HPA300

Pros
  • Simply the best no-nonsense Honeywell air purifier
  • 300 CADR rating; best-performing unit for smoke, dust, pollens, allergens removal
  • Very low price tag, despite being the biggest and latest model
Cons
  • Pre-filters need to be replaced every 3 months; common issue with most Honeywell air purifiers
  • It’s big but not a whole-house air purifier big

2. Honeywell 50250 Review (Best Honeywell Large Room Air Purifier)

Best Honeywell Large Room Air Purifier
Coverage Area: 390 sq ft
CADR Rating: 250
Filters: Pre-filter, True HEPA
Filter Lifespan: 12 (HEPA) and 3 (Prefilter) months
Fan Speeds: 3
Dimensions: 18 x 18 x 19 inches
Weight: 21 lbs
Price: $$$$
Rating: 4.7 out of 5 stars

Honeywell 50250 has a distinctive cylindrical design. This enables 360-degree air intake, increasing airflow, and air purification efficiency compared to standard air purifiers. To ensure the high-performance, the Honeywell 50250 uses SurroundSeal technology to prevent that 360-degree captured air from leaking out of the purifier unfiltered.

The filtration system is the standard Honeywell combo of activated carbon pre-filter, followed by True HEPA filter. Pre-filter with activated carbon takes care of the large particle and odors, while the HEPA filter removes up to 99.97% of the small particles that are 0.3 microns in size or larger.

Together, the airflow and filtration system can achieve a 250 CADR rating, certified by AHAM. This is quite a high rating, and the Honeywell 50250 can have an almost 400 sq ft coverage area.

The real drawback is that it requires quite a lot of power to run (for an air purifier, that is). Low setting runs of 50 Watts, medium on 120 Watts, and the higher fan speed setting at 170 Watts. Generally, air purifiers don’t use a lot of electricity.

All in all, this is one of the most budget-friendly large room air purifiers you can get:

Honeywell 50250

Pros
  • Cylindrical structure enables 360-degree air intake
  • With a 250 CADR rating, it’s more than capable of covering 390 sq ft rooms (with 5 ACH)
  • Budget-friendly pricing
Cons
  • Not quite as capable as the HPA300
  • It’s quite a big and broad air purifier

3. Honeywell AirGenius 5 Review (Best Space-Saving Honeywell Air Purifier)

Best Space-Saving Honeywell Air Purifier
Coverage Area: 250 sq ft
CADR Rating: 170 Pollen, 160
Filters: Pre-filter, True HEPA
Filter Lifespan: 12 (HEPA) and 3 (Prefilter) months
Fan Speeds: 5
Dimensions: 9.7 x 9.7 x 26.8 inches
Weight: 17.9 lbs
Price: $$$$
Rating: 4.7 out of 5 stars

Apart from the HPA series, the AirGenius is the second main series of Honeywell air purifiers. Most of the basic principles of how these air purifiers work is the same. AirGenius 5, the latest and best AirGenius model uses a pre-filter with odor-removing capability, coupled with a True HEPA filter to remove even the smallest particles.

The point of AirGenius 5 is the tower structure. It’s almost 27-inch tall but at the bottom is has a cross-section smaller than 10×10. That makes all tower structured HEPA air purifiers perfect for small cramped rooms. Dyson air purifiers were the ones that perfected the ‘tower’ structure.

AirGenius 5 has a 250 sq ft coverage area and a CADR rating of 160 (170 for pollen). Those specs are very solid and are exactly focused on the reliability Honeywell is known for.

The main difference between AirGenius 5 vs AirGenius 4 and other AirGenius series air purifiers is the number of fan speed settings. It’s quite simple: AirGenius 5 has 5, and AirGenius 4 has 4.

All in all, the AirGenius 5 is a solid-specs Honeywell air purifier that can save you a bit of room due to the tower structure:

Honeywell AirGenius 5

Pros
  • Solid-specs air purifier with a slim and tall tower structure
  • Can achieve up to 160 CADR rating at the highest 5th fan speed setting
  • Customary Honeywell low price for high reliability
Cons
  • Overall CADR rating could be higher
  • Doesn’t come with a dedicated activated carbon filter

4. Honeywell HPA200 Review (Best Honeywell Air Purifier For Smoke)

Best Honeywell Air Purifier For Smoke
Coverage Area: 310 sq ft
CADR Rating: 200 Smoke, 190
Filters: Pre-filter, True HEPA
Filter Lifespan: 12 (HEPA) and 3 (Prefilter) months
Fan Speeds: 3 + Turbo Clean
Dimensions: 19.4 x 11.5 x 20.3 inches
Weight: 13.9 lbs
Price: $$$$
Rating: 4.5 out of 5 stars

Honeywell HPA200 is a magnificent air purifier for medium-sized rooms. It’s appropriate for bedrooms, living rooms, even a kitchen about 310 sq ft in size. The True HEPA filter, coupled with odor-reducing Honeywell A or A+ pre-filter, removes the small as well as large particles and undesirable odors.

As the model number suggests, the Honeywell HPA200 has a 200 CADR rating for smoke removal. It has all 4 cleaning settings; allergens removal, general air cleaning, and germ removal for mold, alongside the all-powerful turbo setting. It’s worth mentioning that germ setting doesn’t really make the Honeywell HPA200 the best air purifier for mold; however, it does help considerably with mold spores.

Obviously, it’s not a powerful as its biggest brother – the HPA300. However, it does have enough air purification power to effectively remove indoor air contaminants from the medium-sized rooms (for which HPA300 would be overkill).

If you compare HPA300 vs HPA200, the HPA200 model also has a lower price tag (the difference is about $50 or so):

Honeywell HPA200

Pros
  • High-performing air purifier for medium-sized rooms (310 sq ft coverage area)
  • Has a 200 CADR rating and 4 available cleaning levels (for allergens, general cleaning, germs, and turbo)
  • About $50 lower price tag than HPA300
Cons
  • Powerful but not as powerful as HPA300 (also has a smaller CADR and coverage area)
  • Smoke CADR is 200, but dust CADR is 190, and pollen CADR is 180

5. Honeywell HPA100 Review (Best Cheap Honeywell Air Purifier For Small Room)

Best Cheap Honeywell Air Purifier For Small Room
Coverage Area: 155 sq ft
CADR Rating: 100
Filters: Pre-filter, True HEPA
Filter Lifespan: 12 (HEPA) and 3 (Prefilter) months
Fan Speeds: 3
Dimensions: 13.9 x 8.9 x 13.5 inches
Weight: 18.5 lbs
Price: $$$$
Rating: 4.4 out of 5 stars

Honeywell HPA100 is the smallest main Honeywell HPA series air purifiers. With a coverage area of 155 sq ft and 100 CADR rating, it’s perfect for small rooms. Here are some room examples:

  • 10×10 rooms with low air quality (200+ Air Quality Index or AQI).
  • 12×12 rooms with low or medium air quality.
  • 14×14 rooms with medium air quality.

The Honeywell HPA100 has all the characteristic Honeywell qualities that include:

  • 2-stage pre-filter and True HEPA filter system.
  • Reliability.
  • Low price.

In fact, because this is a small room HEPA air purifiers, it is also the cheapest Honeywell air purifier. That’s why people do buy several air purifier for multiple rooms:

Honeywell HPA100

Pros
  • Cheapest Honeywell air purifier for small rooms
  • Coverage area of 155 sq ft and 100 CADR rating
  • AHAM verified
Cons
  • It’s not the newest model
  • Cannot be used in bigger 300+ sq ft rooms

6. Honeywell QuietClean Review (Quietest Honeywell Air Purifier)

Quietest Honeywell Air Purifier
Coverage Area: 170 sq ft
CADR Rating: 132 Pollen, 100
Filters: Pre-filter, True HEPA
Filter Lifespan: 12 (HEPA) months; Prefilter is washable
Fan Speeds: 3
Dimensions: 10.4 x 9.7 x 28.7 inches
Weight: 14.5 lbs
Price: $$$$
Rating: 4.2 out of 5 stars

As you have probably figured out from the model name, the Honeywell QuietClean is the quietest air purifier Honeywell offers. It’s a small room air purifier with a 170 sq ft coverage area, 100 CADR rating (132 pollen CADR, mind you), and a peculiar design.

It’s not a great as the HPA series or even the AirGenius 5 air purifier. That being said, it has one distinct advantage:

Washable pre-filters.

With all other Honeywell air purifiers, you’re required to replace dirty pre-filters with new pre-filters. In the case of Honeywell QuietClean, you can just wash those prefilters. That saves you about $20 you would spend on pre-filters every 3 months. In a year, that can lead to $100 savings.

This makes Honeywell QuietClean one of the few air purifiers with washable filters. The top air purifier in this area is the new tech Airdog X5. It’s actually quite remarkable to see a somewhat conservative company like Honeywell to produce washable filters.

All in all, you can save quite a bit of filter with Honeywell QuietClean, it is a quiet device, but sometimes it just lacks the CADR rating and airflow to do the job exceptionally well:

Honeywell QuietClean

Pros
  • Quietest Honeywell air purifier
  • Has washable pre-filters, which can save you up to $100 on pre-filter replacement costs
Cons
  • It could be more powerful or at least have a higher CADR rating
  • Peculiar design not everybody loves

7. Honeywell AirGenius 4 Review (Older Model That’s Still Good)

Older honeywell air cleaner That’s Still Good
Coverage Area: 250 sq ft
CADR Rating: 170 Pollen, 160
Filters: Pre-filter, True HEPA
Filter Lifespan: 12 (HEPA) and 3 (Prefilter) months
Fan Speeds: 4
Dimensions: 12.1 x 12.3 x 30.3 inches
Weight: 8.1 lbs
Price: $$$$
Rating: 4.2 out of 5 stars

AirGenius 4 is actually the predecessor of AirGenius 5. They are quite alike; most of the specifications are exactly the same. The main difference is that AirGenius 4 only has 4 fan speed settings, while AirGenius 5 has 5. Not a big difference, in short.

However, AirGenius 4 is an older model that doesn’t have all the love it got a few years ago. The chances are that it will slowly disappear from the production line.

The nail in the coffin is that, despite AirGenius 5 being newer and better, the AirGenius 4 still costs about $200. If the price dropped to $150, for example, this Honeywell air purifier would be worth it. Now, you do have better alternatives.

Honeywell AirGenius 4

Pros
  • Same specs as AirGenius 5, but with only 4 fan speed settings instead of 5
  • Good track-record
Cons
  • Still costs $200, despite AirGenius 5 being on the market for a bit just a bit more
  • Seems like it will slowly be phased out of production

Honeywell Air Purifiers FAQ

Honeywell is the biggest company that makes air purifiers. Obviously, with so many units sold, consumers have quite many questions regarding how good Honeywell air cleaners actually are. Here we address the most frequent questions (you can pose yours in comments below):

Are Honeywell Air Purifiers Any Good?

‘Good’ is the perfect word to describe Honeywell air purifiers. They aren’t exceptional like Dyson air purifiers, but they are reliable, have pretty good specifications, and will not let you down quickly.

How Long Do Honeywell Air Purifier Filters Last?

Honeywell uses two kinds of filters with different lifespans:

  1. Pre-filters A and A+ last for 3 months. The indicator on Honeywell air purifiers will tell you when you need to replace them.
  2. True HEPA filters last for 12 months. These are the important ones, and it’s important to change them once a year.

Honeywell filters cost about $20-$60, which is quite a low price for air purifier replacement filters.

Do Honeywell Air Purifiers Emit Ozone?

No, Honeywell air purifiers don’t emit ozone. The only air purifiers which emit ozone are the ones with ionizer filters. You can read more about the ozone generators here.

  1. How many HPA300 Air Purifiers would be required to recirculate the air according to CDC guidelines in a music classroom measuring 30’(deep)x40’(wide)x30’ high?

    Reply
    • Hello Linda, it depends on what the ACH (air changes per hour) requirement is by CDC. Usually, 5 ACH is recommended for allergy-prone people. The total volume of the classroom is 30*40*30 = 36.000 ft3. HPA300 has a 300 CFM airflow; that means that it cleans 300 ft3 per minute, or 18.000 ft3 per hour. In short, if the requirement is 1 ACH, you would need 2 HPA300 due to very high ceilings. If the requirement by CDC is 5 ACH, you would need 10 HPA300. Hope this helps.
