Top 10 Best Air Purifiers for Allergies and Asthma in 2019 List

1) Rabbit Air MinusA2 – Quite simply, the best air purifier for allergies and asthma in 2019

 Previously in our list:   Rabbit Air MinusA2.

There’s been a load of stunning best air purifiers for allergies and asthma in 2019, yet the Rabbit Air MinusA2 is certainly the one with the most features. It is not the expensive air purifier on the market, but for both the performance and the value, it can beat every other device on the market without doubt.

best air purifiers for allergies

For the performance, this Rabbit Air MinusA2 packs an unique 6-stage air filtration system to guarantee the best protection against allergies and asthma.

  • Pre-filter & Medium Filter – Double the pre-filtration means double the effectiveness against allergens. These 2-layer filters will guarantee to trap all large and medium particles, for example dust mites, pet hair, large pollen, pet dander, mold and dust particles.
  • Advanced BioGS HEPA Filter – It is a True HEPA Filter that captures 99.97% of all allergens, bacteria, virus particles, pollen, mold and fungi particles down to 0.3 microns. Rabbit Air advances their air filter process, therefore prolong optimal filter efficiency and filter life of their HEPA Filter.
  • Customized Filter – Double the protection with a variety of customized filters for specific needs like Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber. You can tailor the MinusA2 air purifier to fit your personal needs.
  • Activated Carbon Filter – Eliminates household and cooking odors, tobacco smokes and exhaust fumes and VOCs.
  • Ion Generator – Rabbit Air MinusA2 still has ionizer technology to trap even the tiniest particles of pollutant back into other filters. Can be switched on/off.

Expert tips: The amount of ozone is about 0.002 ppm, which is 25 times less than the 0.05 ppm maximum ozone safety standard set by California Air Resource Board – the authorized air cleaning agency in the government of California.

When you look for an air purifier to solve your health problems (allergies and asthma), you must both look at the quantity and the quality of this device’s air filters. Normally, the more filters the more stages to remove the airborne allergens. An air purifier commonly has 3 or 4 stages of air cleaning system, while the Rabbit Air MinusA2 develops to 6 stages, with 5 mechanical layers of air filters.

About the air filters, they are of the excellent quality we’ve come to expect from Rabbit Air. Beside the normal pre-filter, Rabbit Air MinusA2 is installed with one additional medium filter (which is a HEPA-type filter) to eliminate as much airborne contaminants as possible. Even if these impurities can pass the double pre-filter, it won’t escape the high-quality True HEPA filter of Rabbit Air MinusA2. The high efficiency of 99.97% for down to 0.3 microns particles is the best that is recorded right now. And it can last for 12 to 18 months more than the common True HEPA filters, thanks to the necessary support of these double pre-filters.

The Charcoal-Based Activated Carbon Filter from Rabbit Air MinusA2 is made of high-grade granular activated carbon, which is better than the most typical thin layer of activated carbon. Chemicals, smoke and common household odors can be effectively reduced. If you have serious allergies by your pets or cigarette and cigar smoke, you should select the Pet Allergy or Odor Remover Customized Filter, so it can support your Rabbit Air MinusA2’s carbon filter. With up to double filtration against all types of chemicals, smoke, smell and odors, Rabbit Air MinusA2 makes sure to end the allergies and asthma symptoms from you.

Another unique selling point of this Rabbit Air MinusA2 is the Ultra Quiet operation. Powered by an advanced fan, the noise level of this air purifier is even lower than the kind of whisper, and in real-world use, you will not notice any sound at all.

While the smart features in high-end air purifiers don’t help solve your allergies and asthma, we are still happy to use our air purifier easier. The Smart Sensor in Rabbit Air MinusA2 works fantastically well, which accurately detects the change in your indoor air quality to automatically adjust the fan speed. With this feature, you can expect to just turn on your Rabbit Air MinusA2 and forget it, as this air purifier will do everything for you. The Wifi Smart App is useful, too.

There is only one downside, with such low CADR rating as 200 Dust/ 193 Smoke/ 208 Pollen (cfm), the Rabbit Air MinusA2 might take more time to clean your room completely. Especially for a room of 815 sq ft, this air purifier can only exchange the air once in 30 minutes, so you need to wait at least one hour for air cleaning progress.

But overall, the Rabbit Air MinusA2 is by far the most complete on the market – you won’t regret your choice if you pick up this air purifier.

Here is the pros/cons of Rabbit Air MinusA2:

PROS


  • Top-notch performance
  • Advanced Air Filtration process
  • Smart Features like Smart Sensor and Wifi Connectivity function
  • Ultra Quiet
  • 5-year warranty
CONS


  • Low CADR in mid-range segment

2) GermGuardian AC4300BPTCA – Best Under $100 Air Purifier in 2019

 Previously in our list:   GermGuardian AC4300BPTCA.

Some viruses and bacteria in pet dander or the pollen is the most often cause of the allergies. We wonder what is your reaction if you know you can find a great solution for these viruses and bacteria with only $100 budget. The GermGuardian AC4300BPTCA is this solution for your allergies.

best air purifiers for allergies and asthma

GermGuardian AC4300BPTCA has a lovely modern outfit and a fantastic air filtration process for a $100 air purifier. You will feel really good after using it because of the 3-in-1 air cleaning system of GermGuardian is including of these below filters:

  • True HEPA Filter – Claims to capture 99.9% of microscopic allergens, dust and mold spores down to 0.3 microns in size.
  • Activated Carbon Filter – Reduces odors created from smoke, cooking, and pets.
  • UV-C Light – The powerful technology to kill airborne bacteria, viruses and mold spores that cause health issues, but is harmless to human.

The air filter may not run like a high-end air purifier, but it is still a certified True HEPA filter. For the size, this True HEPA filter is not cheap, and the performance of the GermGuardian AC4300BPTCA deserves the class-leader at the budget end of the air purifier market.

But for just a normal True HEPA filter, we won’t consider the GermGuardian AC4300BPTCA to be the best budget air purifier for allergies and asthma. There are many of candidates out there having great True HEPA filter like the Levoit LV-H132, Honeywell HPA060 or the AeraMax 100. Yes, the only thing that this GermGuardian AC4300BPTCA is better than most of the competitors is the signature UV-C light filter. This light bulb is totally harmless to human, it can disrupt the core DNA of the germs and viruses, and destroy them totally. The process is inside the air purifier, and there is no way it can affect you.

Our only real disappointment is its noise level. For a budget device, it seems the company is trading off the fan power for the quality of air filters. We can’t ignore the crackling noise when running this GermGuardian AC4300BPTCA on highest fan speed. Also, the fan power is just only proper for what you pay, with a decent CADR rating of 107 Dust/ 99 Smoke/ 116 Pollen (cfm). So to say, this air purifier is only suitable for a room of 150 sq ft.

Here is the pros/cons of GermGuardian AC4300BPTCA:

PROS


  • Great performance rating
  • Powerful air filtration process
  • Best Deal for low-range segment
  • 3-year warranty
CONS


  • Quite noisy

Review: GermGuardian AC4300BPTCA Review.

Guardian Technologies is a well-known American brand for the solution of air purification. They provide the signature combination of UV-C light and True HEPA filters, for a reasonable price. If you prefer the classic model, you can look for the GermGuardian AC4825 and/or the GermGuardian AC5250PT – which are the Amazon’s Choice for many years.

Or if you can afford better, you can have most of the high-end features packing in this GermGuardian CDAP4500BCA. We also believe the flagship of this company – the GermGuardian AC9200WCA is a good alternative to your air purifier for allergies and asthma. Sadly, for a list of top 10 only, there are many better candidates to compete against this mid-range air purifier.

Below is the family of GermGuardian devices:

3) Honeywell HPA300 – True Allergen Remover in Low-range

 Previously in our list:   Honeywell HPA300.

As the name implies, Honeywell HPA300 is a true Allergen Remover with the highest performance rating among the low-range air purifiers. That’s why in the list of the best air purifiers for allergies and asthma, this Honeywell HPA300 is an excellent contender.

best air purifiers for allergies and asthma

Honeywell HPA300 is far from flashy, but if it’s value for money you’re after then you can’t go wrong. Let’s look at this natural power:

  • Pre-filter – The pre-filter has Activated Carbon filter in it. With this, every issue of allergies and smoke asthma of you won’t linger anymore. However, you need to replace this pre-filter after 3 months.
  • True HEPA filter – The powerful True HEPA filter can capture up to 99.97% of as small as 0.3 microns pollutant particles like pet dander, mold, bacteria and pollen. This Allergen Remover can even capture the 0.005 microns viruses.

What is the successful formula for an air purifier in low-range? 40% of the popular brands will trade off the fan power, while the rest 59% choose to trim down the quality of the air filters, or using an additional of cheap UV-C light filter or ionic filter.

But the last 1%? It will have both the high fan power and one of the most impressive True HEPA filters in the world. Too good to be true? That’s why you need to know about the Honeywell HPA300. Its certified True HEPA filter is undoubtedly impressive with high efficiency of capturing 99.97% of as small as 0.3 microns allergens, even some viruses down to 0.005 microns can not escape it as well.

With an amazing CADR rating of 320 Dust/300 Smoke/300 Pollen (cfm) and 5X ACH, this air purifier will clean your room in a matter of minutes. This fan power is on par with even mid-range budget devices, like the Blueair Classic 405 or the Alen BreatheSmart. Honeywell HPA300 is effective in a room of up to 465 sq ft.

The ACH here is a powerful 5X and an amazing CADR of 320 Dust/300 Smoke/300 Pollen makes you believe that you won’t go wrong. This fan power is on par with even mid-range budget air purifiers. Honeywell HPA300 is effective for up to 465 sq ft.

Our only real quibble is the noise level of this air purifier. With the same budget, the Levoit LV-PUR131 is much quieter than Honeywell HPA300.

Here is the pros/cons of Honeywell HPA300:

PROS


  • High performance rating True HEPA Filter
  • High fan power
  • High CADR and ACH
  • 5-year warranty
CONS


  • Lack of Smart Features
  • Quite noisy

4) Coway AP-1512HH – The best budget air purifier you can buy right now

 Previously in our list:   Coway AP-1512HH.

As the best budget device of the No.1 brand for air purifiers in Korea (the country of the giant Samsung), Coway AP-1512HH can win any conditions to be one of the best air purifiers for allergies and asthma in 2019. Actually, this device is nominated to be the Best Air Purifier not only from Breathe Quality, but also lots of well-known reviewers. Though many years have passed, it seems the Coway AP-1512HH is still the best budget air purifier you can buy right now.

best air purifiers for allergies and asthma

With the 4-stage air purification system, Coway AP-1512HH receives lots of positive reviews in Amazon, the Wire Cutter or many others. The performance rating of this air purifier is the same with the powerful Honeywell HPA300, and therefore, is a real deal to allergens and asthma triggers.

  • Pre-filter – A washable pre-filter will help you capture the large particles of contaminants, from pet hair, human hair and mold.
  • Activated Carbon Filter – This filter works its best to deodorize and trap harmful gas to keep your place fresh and odor-free.
  • True HEPA filter – The high-performance composite True HEPA Filter that captures 99.97% of down to 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
  • Ionic Technology – Vital ionize can trap even the tiniest airborne particles and send it back to other filters. Can be switched on/off.

First, we are checking the fantastic performance of this Coway AP-1512HH. To the core, its True HEPA filter has an exact same quality as the powerful Honeywell HPA300, that is able to capture 99.97% of any allergens, virus particles, pollen, mold and fungi particles as small as 0.3 microns. Aside from that, the ionizer is a vital part to increase the efficiency of this Coway AP-1512HH. It charges the ions to attract any contaminants to be trapped in the True HEPA filter. The combination is widely used in the high-end devices, like the Rabbit Air MinusA2.

The Deodorization Filter, or Activated Carbon filter from Coway AP-1512HH, is also great. It can help eliminate the smaller particles to prolong the life time of the True HEPA filter, also it can absorb most of the chemicals, smoke, household odors and harmful gases.

With such power, it is reasonable why the Coway AP-1512HH has won a lot of certificate and awards, including of the British Allergy Foundation Seal of Approval.

Also, the sound is impressively quiet, if not the best for an air purifier. Moreover, thanks to the Eco Mode (Coway’s Smart Sensor), Coway AP-1512HH will always run at the low setting with virtually no sound. You can turn this air purifier all night to help keep your allergies and asthma away.

With a great CADR rating of 246 Dust/ 233 Smoke/ 240 Pollen, this Coway AP-1512HH can cover up to 360 sq ft.

Here is the pros/cons of Coway AP-1512HH:

PROS


  • Amazing performance rating
  • Advanced air filtration process
  • Smart Features like Smart Sensor and Eco Mode
  • Good ACH and CADR
  • 3-year warranty
CONS


  • The top light can’t be turned off

5) Levoit LV-H134 – Flagship features at a bargain basement price

 Previously in our list:   Levoit LV-PUR131.

As the necessary upgrade to the last year Levoit LV-H133, the Levoit LV-H134 is everything this company needs to jump into the higher level in air purifier market. It won’t be a problem for this American brand, as they have managed to build an active community and loyal customers over just a few years.

best air purifiers for allergiesTop 10 Best Air Purifiers for Allergies and Asthma in 2019

Levoit has improved the air filter since the release of LV-H133, and again, the Levoit LV-H134 will continue with an all-in-one air filter, which consists of 3 stages as below.

  • Pre-filter – This nylon preliminary filter can capture airborne large objects like dust, pet dander, pet hair, lint and fiber.
  • True HEPA filter – A True HEPA Filter can reduce 99.97% of down to 0.3 microns all contaminant particles like dust mites, allergens, pollen, and mold spores.
  • Activated Carbon Filter – This Activated Carbon filter efficiently absorbs smoke, odor, formaldehyde, VOCs and benzene.

We are once impressed by the high quality of Levoit’s True HEPA filter from the previous Amazon’s Best Seller – Levoit LV-H132. For two years, it seems this company has reached a whole new level with the new True HEPA filter of Levoit LV-H134. It is bigger, better performance and can last even longer than the predecessors. Also, the new filter media allows storing more activated carbon to enhance the performance against the smoke, odor and even formaldehyde or Volatile Organic Compounds (VOCs).

The Smart Sensor is now a common feature in the Levoit LV-H134. You can get the real-time feedback of your indoor air quality almost instantly, thanks to the very accurate sensor.

But the main thing that impresses us is the brand new fan power: the fact that the 2019 flagship Levoit LV-H134 fix every problem of the Levoit’s weak fan power with a high CADR rating of 312 cfm. You can see why this air purifier can even cover a room of 710 sq ft.

Here is the pros/cons of Levoit LV-H134:

PROS


  • Solid performance
  • Great add-on Smart features
  • Powerful yet elegant design, with enough mobility
  • Better CADR rating
  • 2-year warranty
CONS


  • A little bit noisy
  • The power cord is weak

6) Blueair Classic 405 – The best mid-range air purifier for those wanting Alexa control

 Previously in our list:   Philips 5000i.

Blueair Classic 405 is a well-known air purifier in every region. It is recommended by both the Swedish Asthma and Allergy Association (which is under the European Academy of Allergy and Clinical Immunology) and Today’s Parent as the best air purifier for allergies and asthma symptoms. If you can pay up more, you can get the Blueair Classic 480i with the same specs and an additional Smart Sensor, but we believe that Sensor is unnecessary for those who just need complete allergies and asthma solution.

best air purifiers for allergies

Blueair is a symbol in the air purifier industry, as their air purifiers are available in no less than 50 countries. They are famous for making only one powerful air filter for their devices. In our Blueair Classic 405, you can choose between these air filters.

  • Particle Filter/ SmokeStop Filter – You can choose from the Particle Filter with the power to capture 99.97% of pollutants such as pollen, dust, pet dander, mold spores, viruses and bacteria down to 0.1 microns. Otherwise, you can pay more for SmokeStop Filter, which has one additional layer of Activated Carbon Filter.

The Particle filter of Blueair Classic 405 shares the same performance as any other True HEPA filter in the market. It combines both mechanical and electrostatic filtration to make sure even the 0.1 microns allergens will not escape the filter. Moreover, the gradient structure of Blueair Classic 405’s filter traps particles of all sizes while maintaining maximum airflow. It resists clogging and won’t re-release particles back into the air, even when the filter is heavily loaded.

To combat against the gases and odors, Blueair Classic 405 uses a SmokeStop filter with highly porous structure made of activated carbon. We spent 3 months to test the air filter of Blueair Classic 405, and we can assure that it is naturally antibacterial. That being said, the air filter will prevent bacteria and mold growth, which are also the top factors to cause allergies and asthma.

The technology of Blueair is called HEPASilent not without a reason. This Blueair Classic 405 operates in a silent mode that is even lower than the noise level of rustling leaves.

As a high-end air purifier, Blueair Classic 405 can be controlled via Alexa. This feature works great, though for most of those who suffer from allergies and asthma, the Smart features are mostly ignored.

Blueair Classic 405 has a powerful CADR rating of 300 Dust/ 280 Smoke/ 300 Pollen (cfm). With such power, this air purifier is capable of cleaning 430 sq ft with no difficulty.

Here is the pros/cons of Blueair Classic 405:

PROS


  • Awesome performance rating
  • Highest quality material
  • Smart features: Alexa Voice Control
  • 5-year warranty
CONS


  • The machine is big and heavy
  • No integrated Smart Sensor

Just like the Rabbit Air MinusA2, the Austin Air HealthMate Plus makes use of the double pre-filtration system. The Medium filter is alone a HEPA filter which grants enough protection against the small to medium size particles like spores or plant pollen. Thanks to these double pre-filter, the True HEPA filter will last longer, up to 5 years. You don’t believe it?

With a True HEPA filter media as large as 60 sq ft, Austin Air HealthMate Plus removes 99.97% of all particles larger than 0.3 microns and 95% of all particles larger than 0.1 microns with ease.

Also, Austin Air HealthMate Plus has and Activated Carbon filter, filled with Potassium Iodide Impregnated Carbon and Zeolite, to remove Volatile Organic Compounds (VOCs), formaldehyde, benzenes, chemicals, gases and odors.

Such unmatched performance is the reason why this Austin Air HealthMate Plus is selected by the U.S government to help protect the residents of Anniston, Alabama during the elimination of chemical weapons. In 2016, it is also widely used to save thousands of residents of Porter Ranch, California against the effects of the Southern California natural gas leak.

This air purifier has a fantastic fan power to be capable for even the large rooms. With CADR rating of 400 cfm and 5X ACH, you can expect to use the Austin Air HealthMate Plus in a room of 1500 sq ft.

However, please note that the Austin Air HealthMate Plus is a real machine which operates with high noise level. If you can’t stand the noise, you should choose other air purifiers in this list.

Here is the pros/cons of Austin Air HealthMate Plus:

PROS


  • Impressive fan power
  • Top-notch performance rating
  • High-quality True HEPA filter
  • Well-built with highest quality materials
  • 5-year warranty
CONS

    3. Pet – Without the Activated Carbon filter, the Pet air filter uses the Alen’s patented Molecular Conversion Powder to ensure heavy pet odors are destroyed at a molecular level.
    4. Heavy Odor – Alen BreatheSmart 75i changed the Molecular Conversion Powder in the Pet air filter to make the new Heavy Odor filter, which can remove the household odors from smelly kids/teenagers, kitchen garbage, and other everyday activities.
  • Ion Generator – The ionizer is used to improve the efficiency of this Alen BreatheSmart 75i. Can be switched on/off.

Overall, whichever True HEPA filter you are using, the Alen BreatheSmart 75i is capable of removing 99.97% of as small as 0.3 microns pollutant particles. If you have asthma triggered by the strong odors, you should use the Pet or Heavy Odor filter.

Undeniable, the Alen BreatheSmart 75i operates quietly as the noise level is only 25 db, just the same as the Rabbit Air MinusA2. It is even quieter than the noise level of the whisper, and you barely can hear a sound from this device. Moreover, the Alen BreatheSmart 75i can generate soothing pink noise – a frequency proven to help you sleep 25% better.

This air purifier can cover a room of 1300 sq ft, with CADR rating of 347 cfm. With better fan power, the Alen BreatheSmart 75i can clean a room faster than our today champion – the Rabbit Air MinusA2.

Finally, we have a great Smart Sensor for this Alen BreatheSmart 75i. With many tests, it is safe to say that its sensor is the most accurate and fastest in the market. It will always let you know the status of the air quality around you, and change the fan speed automatically to suit it. This is the most reason why this Alen BreatheSmart 75i can defeat the Blueair Classic 605, which doesn’t include an air sensor inside.

The HyperHEPA filter from this air purifier is inferior to IQAir HealthPro Plus, but it is powerful enough to be better than any other True HEPA filters. The bottom line is the unchallenged top-notch performance of its Cartridge-based Activated Carbon filter. The highest quality ABS plastics of this filter can remove any harmful chemicals, formaldehyde, smoke, odors and Volatile Organic Compounds (VOCs).
