If you’re one of 300 million people who suffer from allergies or asthma, you are well familiarized with rhinitis, difficulty breathing, and shortness of breath.

Finding the right solution to fight allergies and asthma is crucial for your life quality and well-being. Nothing beats the feeling when you can breathe clearly and deeply. And it can last forever!

Apart from inhalators, asthma pills, antihistamines, and other medications that you may use to ease your condition, there is a device that helps you in the long run – air purifier.

You might be surprised, but the indoor level of pollutants is nowhere lower than the outdoor, contrary to popular belief. Not to talk about living with your pets if you experience allergies!

In such conditions, this device tremendously helps you – you are going to learn how later on – and is a priceless addition to your home.

The best air purifier for allergies and asthma is difficult to pick out before you do thorough research, and helping you choose is our task for today.

We’ve compiled the list of the ten best purifiers for allergies and asthma after we tested, evaluated, and reviewed them.

Let’s begin!

The 10 Best Air Purifiers for Allergies and Asthma in 2020

1. Rabbit Air MinusA2 SPA-780A

Our first pick, the Rabbit Air SPA-780A, certainly deserves to be crowned one of the best air purifiers for allergies.

The manufacturers advertise this second-generation air purifier as “the brainiest air purifier yet,” and, no matter how pretentious it sounded to us at first, it deserves such a reputation (at least if we speak about their assortment of air purifiers).best air purifier for allergies and asthma - RabbitAir MinusA2 Ultra Quiet HEPA Air PurifierMain features:

  • Advanced BioGS HEPA Filtration
  • Customized multi-layer Filter
  • Six stages of purification
  • 200 pollen / 193 dust /180 smoke CADR
  • Silent speed feature
  • 5-year warranty

Our Detailed User Experience

As the Rabbit Air MinusA2 SPA780A is entirely customizable, the two choices that pertain to defense to allergies and asthma are the germ defense and pet allergy defense filters. 

We’ve tested them both, and they are equally superb in their areas of operation.

The former specializes in trapping and eliminating airborne bacteria and mold (this is the best air purifier for mold), whereas the latter deals with pet dander and allergens (it’s perhaps not the best purifier for pet allergies and asthma, but it’s certainly in top five).

It has an exclusive, BioGS HEPA Filter. What does this mean?Basically, it is an enhanced version that traps allergens and particles at even greater efficiency than the regular HEPA Filter.

The whole construction of the purifier operates on six stages: first, there is a pre-filter for larger particles, followed by a medium filter and the BioGS HEPA filter we mentioned; next, there is a customized filter you choose, an activated carbon filter, and a negative Ion generator at the end.

What this translates to is fresh and clean air.

You can position this air purifier on a particular surface, or you can mount it on the wall, and it has a smart light sensor that automatically switches it to sleep mode during the night.

The coverage is 815 sq.ft., twice an hour on the highest protection setting, and it has five fan speed modes, with the Silent speed noise level of only 20.8 dBA.

Even if you use it all the time (approximately 12 hours a day), the filters will last around two years due to the economical Energy Star rated motor.

Of course, physical features are not our primary area of interest – to us, what matters is how good and beneficial an air purifier is, not its design. 

But the design of this one cannot go unmentioned, as there is an option to get a customized panel with images, including some of the most famous works by Claude Monet and Vincent Van Gogh, as well as with creative illustrations by Rabbit Air. In that way, the Minus A2 SPA-780A does not only better your condition – it also boosts your decorations.

Having said that – we cannot help but praise the customizability of this air purifier once again. It’s basically as if you get an air purifier specifically tailored to your needs!

Pros:

  • Advanced filtration system
  • Completely customizable
  • Sleek design
  • Long warranty
  • Large range
  • Ultra-quiet
  • You get a wall mount kit

Cons:

  • The carbon filter doesn’t trap odor that efficiently (but works great for smoke)
  • A bit expensive

2. Levoit Core 300

Our Rating: 91/100

If you asked us what is the runner-up of the best air purifier for asthma and pets, the answer is the Levoit Core 300.

It has a couple of advantageous features many other air purifiers lack, and it fulfills most, if not all, of our criteria.

Let’s break down the details.Main features:

  • Three fan speeds
  • Vortex Air technology
  • HEPA filtration
  • Timer
  • Display Lock
  • 215 square feet coverage
  • Sleep mode
  • 145 pollen / 140 dust / 141 smoke CADR
  • 1-year warranty (plus one free additional year if you register it)

Our Detailed User Experience

The Core 300 is a complete package, offering excellent and consistent protection, compactness, and beautiful design – all of that at a reasonable price.

What accounts for its protective features is the premium combination of the 3-in-1 HEPA filter, ultra-fine Pre-filter, and an AC (activated carbon) filter. In that way, it can trap particles as delicate as 0.3 microns, but also large allergens (pollen, dust, pander, etc.).

While the original filter is excellent for allergies and asthma on its own, you can get a variant with a specialized pet allergy filter or with a toxin absorber filter that is especially good at preventing symptoms of the condition, respectively.

Best Air Purifier for Allergies and Asthma - LEVOIT Air PurifierAlso, keep in mind that the Pre-filter of this purifier should be cleaned approximately every three weeks in order for it to preserve its maximum effect, while the other two should be replaced every six to seven months. Of course, this depends on your use, but we’re talking about the standard here.

The whole filtration technology is enhanced with Vortex Air technology for strong airflow, enabling coverage of up 215 sq.ft with up to 6 air changes per hour.

Another method that this Levoit air purifier utilizes is the Ozone-free filter (instead of using UV/Ion light, which sometimes can harm ozone).

Actually, the whole device is pollution-free. 

In addition to the fact that it does not harm ozone, this device also prevents noise pollution. It offers undisturbed Sleep operation mode with QuietKEAP Technology that reduces noise to only 24dB. 

The display light can also be turned off, and there is a timer for 2, 4, 6, or 8 hours. The state of the filter is also displayed there so that you know when to change it.

If you’re interested in the minimum time the unit takes to clean the air, it is around 12 minutes for quick purification. Quite incredible, huh?

We believe these are the reasons it is so well-accepted: it is Energy Star verified and complies with CARB (California Air Resources Board) standards for indoor devices. The awards don’t stop there – it is also ETL listed and CA PROP 65 certified.

A pro tip: The sensor that picks up the air is on the bottom of this machine (whereas it’s exhausted from the top), so you should position it on a surface such as a table, or at least elevate it a bit off the floor so that it can achieve its full potential.

Pros:

  • 3-in-1 HEPA Filter
  • Exceeds all safety standards
  • Quiet operation
  • Precise user manual & quick start guide

Cons:

  • Filters require replacement more often than with some other air purifiers

3. Germ Guardian AC9200W

Our Rating: 90/100

The Germ Guardian AC9200W is a mid-range air purifier that could be a strong competitor to the best air purifier for asthma because it is studded with a great number of features that alleviate symptoms.

Guardian Technologies went out of their way to ensure that this model is user-friendly, and let’s see what it offers.Best Air Purifier for Allergies and Asthma - Germ Guardian High CADR True HEPA Filter Air PurifierMain features:

  • True HEPA filter
  • UV-C light
  • Pre-Filter
  • Charcoal Filter
  • 216 dust / 265 pollen / 216 smoke CADR
  • 335 square feet coverage
  • Three fan speed settings
  • Ultra-quiet mode
  • Programmable timer
  • 3-year warranty

Our Detailed User Experience

The manufacturers have managed to pack a three-stage filter into an air purifier that is not too expensive.

Namely, it has the True HEPA filter (responsible for dust, pollen, mold, dander, etc.), combined with the Pre-filter that traps even larger particles (such as pet hair, etc.). The Pre-filter has another function – it prolongs the life of the HEPA filter so that you need not change it as often.best air purifiers for allergies and asthma - Apart from these two reliable filters, there is also the Charcoal filter. Its primary purpose is that it reduces pet odor, smoke, and other gasses.

This air purifier also comes with the UV-C light technology that employs Titanium Dioxide to reduce airborne viruses, germs, bacteria, and mold. This technology must be carefully chosen when asthma is in question because a low-quality one could do more damage than good.

For instance, a poor quality UV-C light can emit ozone, which is something you surely want to avoid. So, we made sure to test out this technology before approving it!

It is also Energy Star certified, verified by CARB (California Air Resources Board) and AHAM (Association of Home Appliance Manufacturers).

The numbers speak for themselves about the efficiency of this air purifier – with 216 dust, 265 pollen, and 216 smoke CADR and three fan speed settings, this device is very fast and can change air four times per hour in rooms up to 335 square feet.

What about smart features?

The AC9200W seems to have them all – a timer that you can program to up to 5 hours, the UV-C light and Ionizer touch control, the Sleep mode, and the filter change indicator atop of a handy handle you can use to carry the purifier from one room to another.

In sleep mode, the noise level reaches only 12dBA, and at the highest speed, around 50. Your clock will basically be louder than this air purifier!

The only limitation is that you cannot dim or turn off the blue light it emits. However, the light is really subtle, and it didn’t bother us at all, even when we tested the purifier overnight.

Pros:

  • Powerful
  • Adjustable
  • Ultra-silent
  • Energy-saving
  • The Ion and UV can be turned off
  • It removes all the traces of cigarette smoke
  • Compact & portable

Cons:

  • You can’t dim or turn off the light

4. Coway Mighty AP-1512HH

Our Rating: 95/100

By combining the standard quality and premium features with a compact and modern design, Coway has really hit the home run with their Mighty AP-1512HH air purifier.

You can get a black or white variant, and no matter which one you choose, it’s going to look great in your room with the attractive glossy finish. But let’s proceed to what is more important – its features and performance! Main features:

  • The True HEPA filter
  • 4-stage Filtration technology
  • Pollution sensor
  • 246 dust / 240 pollen / 233 smoke CADR
  • Three fan speeds
  • Auto turn-off feature (Eco mode)
  • Filter replacement indicator
  • 361 square feet coverage
  • Timer (1/4/8 hours)
  • 3-year warranty

Our Detailed User Experience

As with Coway’s other air purifiers, filters are high-quality and long-lasting, but we clearly noticed some upgrades here.

There is a 4-stage filtration: first, a Pre-filter for largest particles, followed by a Deodorization filter for odor elimination, and the famous True HEPA filter (this one accounts for 99.97% of the particles), and the Vital Ion filter at the end, which is especially effective at eliminating smoke.

Such an advanced system means that allergens and pollutants will not stand a chance to survive in your room.

Although it’s a few years old, the Coway Mighty AP-1512HH air purifier comes with all the smart features that some of the most recent purifiers even lack. So, its age can only be seen as a benefit: it has come down in price to be very affordable in its category.

Which smart features are we talking about?

First and foremost, there is a brightly colored LED that notifies you about the clarity of the air in your room in real-time. This is what we think when we say “some features that some modern devices lack”!

Next, it packs a light indicator for the filter lifetime that tells you when it is the time to replace a filter (both the Pre & HEPA filter), as well as a timer. 

Oh, and it also has a smart turn-off feature. Namely, when no pollutants or allergens are detected for more than 30 minutes, the device will automatically switch to the Eco mode that saves energy by stopping the fan.

Accommodating rooms up to 361 square feet, and with a quite satisfactory CADR (dust 246, pollen 240, smoke 233), this air purifier is very efficient for allergies and asthma.

You can manually adjust the three speeds of the fan, or you can turn on the Auto mode to automatically optimize them based on the sensor that analyzes your air quality. Wow!

The ultimate piece of information we wanted to share for this air purifier concerns some specs – it has 77W power consumption, and it is not noisy at all, with the level of noise from 24.4 to 53.8 dBA.

Pros:

  • Efficient
  • Durable HEPA filter
  • Rich with additional features
  • High-quality features
  • Excellent value for the price
  • Has an Auto mode

Cons:

  • We prefer an AC filter for smoke control to the Vital Ion filter

5. Honeywell HPA300

Our Rating: 99/100

Make some space for the absolute king of air purifiers for allergies and asthma, and the best air purifier overall on today’s list, the Honeywell HPA300.

To show you why the Honeywell Air Purifier HPA300 reigns supreme in this field, we have to dissect its features and get you acquainted with them!Main features:

  • HEPA Filter
  • A+ Honeywell Pre-Filter
  • 465 square feet coverage
  • Turbo clean feature
  • Four cleaning levels
  • Touch controls
  • Timer
  • Control panel dimmer
  • 300 dust /320 smoke / 300 pollen CADR
  • 5-year warranty

It may look like a replica of other air purifiers by Honeywell, but they have really upped the ante on the desirable features of this one.

An improvement in the filtration sector is the most noticeable and also the most important. 

Namely, the certified HEPA filter that this purifier contains captures up to 99.97% of microscopic allergens, including smoke, pet dander, dust, mites, pollen, etc. At the same time, it reduces airborne germs, such as viruses, bacteria, and mold spores.Pair that up with the A+ Genuine Honeywell Filter that captures larger particles, and you get the best protection out there. By the way, always monitor the filter indicator light that will remind you when it’s the time to change your pre-filter (around every three months).

What further testifies to the quality of this Honeywell air purifier is the AHAM (Association of Home Appliance Manufacturers) certification for high values and safety when filtering the air.

When it comes to its allergen-protective power, the numbers speak for themselves – 300 dust, 320 smoke, and 300 pollen CADR is among the highest you can get.

Delivering the full potential for customizing is another benefit of the HPA 300. 

By this, we mean that you can use an auto-off timer, switch between three modes (allergen/general clean/germ), and also make use of turbo power clean settings that will have your air cleaner in a matter of minutes. 

Did we mention that you can even control the brightness of panel lights?

If you choose the standard setting, the air changes per hour in the 465 square feet room, and it is exhausted out of the top of the device.

Aside from being a bit louder compared to some other air purifiers, there are no disadvantages to the HPA300.

The final thing we wanted to mention in this Honeywell air purifier review is its price. It wears a very reasonable price tag. You get what you pay for – a well-rounded and efficient air purifier for allergies and asthma.

Pros:

  • Super-effective at destroying allergens
  • Eliminates allergens for good instead of trapping them
  • Adjustable
  • Certified technology
  • Smart features
  • Outstanding performance
  • Excellent value for the price

Cons:

  • However efficient it may be, Turbo speed mode is just too loud

6. Levoit  LV-H134

Our Rating: 92/100

It’s time to review the second Levoit air purifier on our list, the LV-H134.

If we were to compare the two, we would say that the former one, Core 300, is better for asthma and that the LV-H134 is better if you want a more rounded-up air purifier (but also more pricey).Main features:

  • True HEPA filter
  • AC filter
  • 1170 square feet coverage
  • Smart auto mode
  • Sleep mode
  • Timer
  • Filter indicator light
  • 360° suction
  • Energy Star certified
  • 1-year warranty (can be extended to two if you contact the manufacturers)

Our Detailed User Experience

To begin with, the True HEPA filter, which we’re sure you already know, makes this air purifier an excellent choice if you suffer from allergies caused by pet fur, hair, lint, dust, and pollen.

Its performance is enhanced by the Pre-filter that also protects the HEPA filter (which is more expensive) so that you don’t have to change it that often.

The final bit of this efficient system is the AC (activated carbon) filter that works against gasses, odors, smoke, etc.The productivity of this air purifier isn’t only exhibited in its premium three-stage filtration. The fact that it can purify the air in 1170-ft² rooms in only 30 minutes and 18 in 710-ft² rooms simply equals efficiency and functionality. Such an ample coverage space makes this air purifier appropriate for a couple of rooms.

Although this is a second consecutive air purifier that has a smart Auto mode, this feature is quite rare, and we always praise it. 

Namely, there is a sensor that detects particles and calculates the exact mass per volume within 30 seconds. This result allows the device to adjust the fan speed automatically according to the quality of the air.

All the boxes for other extra features can be checked, too – there is the timer, the feature that turns off the display (yes, we couldn’t really come up with a good name for it), and the filter indicator light.Once the air quality and speed are detected, there is a powerful 360° suction of the air from all sides, just like with most of the air purifiers in Levoit’s assortment. When it is cleaned, the fresh air is pushed out from the top of the purifier.

No noise pollution here – the Sleep mode filters the air with an incredibly low noise level of 25dBA.

Besides, LV-H134 is good for your wallet (not like its sibling, Core 300, but close). Not only does it come at an affordable price, but it also saves energy with a rated power of 45W (much lower than that of similar-grade air purifiers). 

In practice, this means that it will cost only around $1.40 per month in case you use it for 24 hours a day (and you probably won’t)!

Pros:

  • Noiseless
  • Inexpensive, as it consumes less power
  • Captures all kinds of particles
  • Broad coverage
  • Sports a wide variety of extra features
  • Portable

Cons:

  • The one-year warranty seems short compared to the other models

7. Coway Airmega 400 

Our Rating: 91/100

The Coway Airmega 400 has quickly become one of the best-selling air purifiers on the market, and after evaluating it, we can really tell why.

In general, we were pleased with the number of smart features it offers and its efficiency. There aren’t many compromises to make with this one except for the price.

If you don’t mind cashing out a few extra bucks, though, we can promise that the Coway Airmega 400 will help you with allergies and asthma.Main features:

  • Max2 Filter (True HEPA Filter + AC filter)
  • 1560 square feet coverage
  • Pollution sensor
  • Three fan speed settings
  • Smart mode
  • Sleep mode
  • Timer
  • Energy-star certified
  • 1-year warranty + 5-year warranty on electronic parts

Our Detailed User Experience

As you know, the HEPA filter is a precondition that we even consider an air purifier an appropriate choice for allergies and asthma. Those that did not have didn’t even pass the initial selection.

So, you may be surprised when you see that this one has the “Airmega Max 2” filter – but don’t let that misguide you, as it is actually a premium combination of an AC (active carbon) filter and the True HEPA filter.

We’ve already told everything about this combination of filters, but to emphasize it again, they remove virtually anything unwanted from the air. While the HEPA filter captures and eliminates allergens such as pollen, dander, etc., the AC filter deals with fumes, gasses, and other pollutants.

Also, it has several smart features we missed on some other picks.

For example, there is the pollution sensor in the shape of a LED ring that notifies you about the real-time air quality of your room. What you want to see is blue or green light, as it signalizes clean indoor air, whereas yellow and red mean that there are a lot of pollutants present!

Additionally, you can set it up to as many as five fan speed modes. Apart from the usual three (low, medium, high), there is the Smart mode that optimizes the speed in accordance with the quality of the air it detects, as well as a Sleep mode for the night.

At lower levels, you can barely hear it, and with the highest setting, we expect around 50 dBA, based on our previous experience. The Airmega 400 manages to beat even that, as it reaches only 43.2 dBA at the maximum setting.More importantly, it works very efficiently. The powerful dual suction draws the air on two sides, and when it’s cleared, it pushes it out of the top.

Next, there is a timer that you can set to 1, 2, 4, or 8 hours, and a light that indicates the filter lifetime (for both filters).

Just like many of our other picks, this one is Energy Star certified and energy-saving – it won’t cost you a lot, even if you use it 24/7.

Pros:

  • Eradicates all the harmful particles from the air
  • Has an air quality indicator
  • Fast
  • High room coverage
  • Extremely quiet
  • High CADR
  • Smart properties

Cons:

  • The filter replacement is costly
  • The AC filter doesn’t really prolong the durability of the HEPA filter

8. Blueair Classic 605

Our Rating: 95/100

The Blueair Classic 605 is another one of the best air purifiers for allergies and asthma for our readers who want a more advanced health companion.

This upgraded version of the Classic series by Blue Air helps eliminate more particles than ever and has excellent construction.

Let’s elaborate on that in detail.Main features:

  • HEPA Silent filter
  • 775 square feet coverage
  • Three fan speed modes
  • CA filters purchased separately
  • Stainless steel
  • Wi-fi connection
  • Alexa voice control
  • Blue air friend app control
  • 1-year warranty (but can be extended to 5 if you register your device within 60 days from the purchase)

Our Detailed User Experience

The steel body of the unit guarantees that this air purifier will last you for years to come, and it doesn’t lack in the highlight features department, either.

As for the filters, it has the True HEPA filter that comes with HEPASilent technology. It is impeccable at removing pollutants and allergens; however, the device does not include additional filters.You can purchase Dual-Protection filters that are sold separately at an affordable price, though we really wish they were included in the purchase. If you’re buying this air purifier for asthma, it is vital that you get those filters with an extra level of active carbon so that it removes smoke and other pollutants.

The coverage area of 775 square feet is solid, and the air can change five times per hour with the highest speed. There are three fan speeds, as well as the Sleep mode that reduces the noise and turns off the light of the purifier.While the operation is very noiseless when the Sleep mode is on (32 dBA), the highest speed of the fan is a bit loud with 62 dBA. But it’s important that there is a silent mode that you can turn on during the night!

It has a better smart-feature layover than most of the air purifiers on the market and is an excellent pick for tech-savvy enthusiasts among you.

Specifically, the Classic 605 is unique because it supports wi-fi connection, and you can control it from the Blueair friend app that is available both on Google Play and on the App Store. What is more, it is compatible with Amazon Alexa, so if you own one of these, this is the pick for you!

What you can do via these remote controls is to monitor the real-time air quality, adjust the speed, or opt for the Auto mode so that the device does it for you. It also allows you to set up the timer (e.g., schedule the Night mode and/or turn off).

Pros:

  • High-quality materials
  • Compatible with Alexa
  • Can be controlled via an app
  • Long warranty
  • Steady performance
  • Efficient air cleaning

Cons:

  • A bit heavy & robust
  • Protection filters are not included in the purchase

9. Austin Air HealthMate B450B1

Our Rating: 95/100

The Austin Air HealthMate B450B1 air purifier is neither the most advantageous nor the most simple air purifier out there. 

We liked it for its health benefits, as it is, above all, an excellent air purifier for allergies and asthma on a budget.

Main features:

  • Medical-grade HEPA filter
  • AC Pre-Filter
  • Carbon & zeolite mixture
  • All-steel perforated intake of the air
  • Three fan speed settings
  • 1500 square feet coverage
  • Caster wheels
  • 5-year warranty

Its capability to reduce harmful chemicals and micron particles with a premium medical-grade HEPA filter and 780 cubic inches of activated carbon (this one is an upgrade compared to the previous version) is magical. 

It eases symptoms of allergies and asthma, including headache, wheezing, sneezing, runny nose, etc.

This broad-spectrum protection also encompasses larger particles that may cause allergies, such as smoke, pet dander, and pollen.

The air passes through a 4-stage filter (Pre-filter for larger particles, then the medium particle Pre-filter, AC filter for smoke and odors, and finally, the aforementioned HEPA filter).

The double pre-filtration is something we do not see often, and such a combination can deal with 3000+ kinds of toxic substances.Also, due to the careful construction and implementation of filter layering, the HEPA filter of this device can last for five years before you need to replace it, and that’s probably the longest time we’ve come across.

There are three fan speed modes for quick cleanse of the air, with a 360-degree-intake of the air from all sides. Due to the fan power, it can cover considerably large space – among the broadest out of all purifiers – 1500 square feet!

Does this amount of power come at the cost of noise reduction?

Well, to be honest, it does. 

The level of noise at the medium setting is around 50 dBA, which is okay – it will sound perhaps quieter than the average fan. However, we don’t recommend using it at higher speed settings during the night – it reaches around 66 dBA, and will most likely disturb your sleep.

Austin Air’s motto is, notably, “Quality over quantity,” and we can’t blame them for that. So, while this air purifier does not sport a lot of additional features (such as the timer or indicator light), it still performs exquisitely.

Another good thing about your future health mate by Austin air is that it utilizes a PSC (Permanent Split Capacitor) motor to reduce power consumption by drawing less current, so you save up in the long run. 

When we compare it to the other air purifiers, there is a fact that cannot be ignored. At 47 pounds, it is a bit robust and among the heaviest out there, but this shouldn’t be a significant problem, as it contains casters if you want to quickly move it from one room to another.

Pros:

  • Long-lasting protection
  • Double pre-filtration
  • Budget-friendly
  • Excellent performance
  • Broad coverage
  • Adjustable
  • Energy-saving

Cons:

  • We wish it came with more “smart” features
  • Heavy (though easy to transport)

10. IQAir HealthPro Plus Air Purifier

Our Rating: 89/100

Last but not least, the IQAir HealthPro Plus air purifier deserves to be on the list of best air purifiers for allergies and asthma for its high-quality performance.

This Swiss-made air purifier is widely recommended as one of the best air purifiers for allergies and asthma, so, naturally, we had to lay our hands on it.

We’re pleased to report that it is indeed an excellent one, so, without further ado, we can proceed to its review.Main features:

  • HyperHEPA Filter
  • Oxidation
  • AC filter
  • Triple-seal
  • 1125 square feet coverage
  • EvenFlow Diffuser
  • Remote control
  • 1-year warranty (can be prolonged to the 10-year limited warranty if you register your unit within 30 days from the purchase)

Our Detailed User Experience

This air purifier, in particular, features a bit different HEPA filter than the one that we are used to, and the company patented it so that it protects you not only from the standard allergens but also from bacteria, viruses, tobacco smoke, etc. 

They nicknamed it HyperHEPA filtration, and what is also excellent is that it lasts around four years, so it is practical and money-saving in the long run!

With the method called “pelletized chemisorption” that employs an oxidation process, all of the harmful chemical substances from the air are destroyed, and the granular AC (activated carbon) absorption eliminates odors.What contributes to the efficiency of the filtration system is the Triple-Seal technology that serves to eliminate any air leakage once it has been brought to the purifier. It seals the frame of the filter to the unit so that everything is perfectly air-tight.

Besides the advanced filtration technology, this air purifier has a lot to offer in other departments.

The manufacturers have also patented the EvenFlow Diffuser that distributes the filtered air in 320° manner, which wasn’t something we were used to – the air usually comes only from the top of an air purifier. It is really enjoyable, though, as the air is distributed evenly in all directions, without making too much noise.

Speaking of the air distribution, the fan has been upgraded so that it offers fast performance. However, it comes at the expense of power consumption. Though it only uses 27 W at the lowest speed, with 215 W at the highest speed, it is not the most energy-saving air purifier out there.Lastly, it has something that all of our other picks lack – the intuitive remote control. You can use it to turn your device on and off, program the settings, monitor filter life, etc. We wish it came with an Auto mode, as well, though, as most of the other smart features are present, too.

Pros:

  • Excellent fan power
  • Ultra-quiet
  • High-quality filters that eliminate virtually anything
  • Distributes air evenly
  • Comes with wheels
  • Long-lasting HyperHEPA filter
  • The longest warranty (once you register the product)

Cons:

  • High power consumption in high-speed mode
  • A bit pricey

Air purifiers not only improve your overall health condition, but also significantly help people who have problems with allergies or asthma, and manage their symptoms in the long run.

However, questions like: “Is it efficient?” “Can air purifiers make asthma worse sometimes?” and similar doubts are entirely understandable.

You have to know the science behind the mechanism of work of air purifiers in order to understand how they benefit allergies and asthma.

Furthermore, there is a wide variety of air purifiers and not every air purifier is excellent for such purposes – you need to know how to pick one.

Stay tuned, as we’re about to address that (and more) below!

#1 How Air Purifiers Work: The Prolegomenon

The primary thing you need to understand is how air purifiers function so that we can discuss how it alleviates allergies and asthma symptoms.

In broad strokes – air purifiers consist of a fan and one or several filters.

Once the fan picks up the air, it moves through the filter(s) that clear the unwanted particles in the air (they are either captured or eliminated), and it exhales the clean air out.

Let’s see how this technology applies to allergies and asthma.

#2 How Air Purifiers Work for Allergies and Asthma: The Explanation

  • HEPA filters capture virtually everything that may worsen your condition.

To be called HEPA, the filter must meet specific standards, most notably, that it has to remove at least 99.97% of particles as small as 0.3 microns.

In practice, a high-quality HEPA filter removes almost all the allergens and particles that may affect your asthma, such as dust, smoke, pollen, pet dander, etc.

It is made of fibers that remove those factors that affect your health in three ways: by capturing larger particles (larger than the fibers), by intercepting mid-size particles, and by diffusing ultra-fine particles.

Overall, HEPA filters are the canon for air purifiers that work for allergies and asthma, and you shouldn’t buy a purifier without one.

  • AC filters capture what HEPA filters don’t.

While HEPA filters are really revolutionary in the history of air purifiers and prevalent for their efficiency against allergies and asthma, they do not control everything.

For instance, they aren’t the most efficient at catching gasses, e.g., VOCs that are emitted from adhesives, chemicals, cleaning products, paint, etc. 

This is more important for asthma than for allergies, as allergens are most often covered within those particles that HEPA filters clean. But if your asthma symptoms are triggered by airborne gasses, you might want to purchase an air purifier that has an AC (active carbon) filter in addition to HEPA.

They are also the best for dealing with tobacco smoke.

  • They clean the air efficiently.

Most of the air purifiers are very fast (or at least they have various speed settings), so that, usually, all it takes for them to remove temporary allergens and pollutants is a couple of minutes (15 or so).

So, if someone has recently smoked a cigarette, or it’s spring – your health assistant is there to save you in a matter of minutes.

It is sometimes measured in CADR (Clean-Air Delivery Rate) index. At their best, air purifiers can score around 300.

#3 Additional Steps You Should Take to Ease Your Condition

Of course, no matter how good an air purifier is, there are some precautions that you ought to take to make the most of their health benefits:

  • Don’t forget to change your filters. 

This is paramount, and we won’t get tired of repeating it (literally): do not forget to change your filters

This can have tremendously adverse effects, as all the allergens and toxic particles an air purifier has picked can go back to your air. 

There is no universal formula on how long does it take before you need to change one – it all depends on the kind of the filter, and can range anywhere from a couple of months (in rare cases, weeks, even) to around five years. 

If there isn’t an indicator light that will remind you it’s time to change the filter, always be informed about the ones that your air purifier has!

  • Keep your windows closed when an air purifier is working.

This pertains to you if you are allergic to pollen and other outdoor allergens – you don’t want them to come into your room again and again while the poor air purifier in the corner is struggling to eliminate them.

However, when it’s not running, make sure that the area is well-ventilated.

  • Use a HEPA-based vacuum cleaner.

It can sometimes happen that dust and other particles that the air purifier has cleaned from the air remain (or, as we like to say, escape) on the floor. 

To make sure that the whole area is completely clean, the HEPA filter vacuum cleaner + the HEPA filter air purifier are the unequaled combo.

#4 The Bottom Line

As you can see, the air purifiers work for allergies and asthma because they limit your exposure to allergens and polluters in your home environment.

They do so in different ways, and your state will require a particular type of air purifier, but now you know everything in order to make an informed purchase.

Now that we’ve covered all the basics, all that is left is to proclaim the winners!
