If you are sensitive to pollen, dust or pet dander, investing in the best air purifiers for allergies can bring much needed relief to your symptoms. That is because these smart appliances can trap and remove a wide range of airborne allergens, helping you to breathe cleaner, fresher air in your home or workplace.
We may not be able to seem them with a naked eye, but there are many different particulate matters in the air around us, and some can trigger asthma attacks and symptoms of allergies, Wei-Ning Wang, an associate professor in the Department of Mechanical and Nuclear Engineering at Virginia Commonwealth University, told Live Science. "Examples include dust, pollen, mold, smoke, and airborne bacteria and viruses,” he said.

11. How we test
These airborne particles are not easy to trap, which is why the best air purifiers for allergies are equipped with a number of advanced technological solutions that may not be featured in some of the more basic appliances. For example, most air purifiers for allergies come with a High Efficiency Particulate Absorbing (HEPA) filter, a piece of tech able to trap 99.97% of indoor air pollutants down to 0.3 microns in size. Many appliances will have extra filters that capture pet hair or reduce bad smells caused by pets, smoke and cooking. However, this also means that air purifiers for allergies tend to be on the pricier side.
We know that choosing the right model is not easy, which is why we have tried and tested a vast range of air purifiers specifically designed to ease the symptoms of asthma and allergies. We have looked at price, size, design, and ease of set up, but most importantly, performance. Here is our extensive guide of the appliances that really work. But if you are looking for something different, check our general guide to the best air purifiers.
Most powerful and best overall performance
Our expert review:
Warranty: 2-year limited
Weight: 13.7 lbs
HEPA filter: Yes
Energy star certified: Yes
+Easy to use and control via app
+Quiet and discreet
-May be too bulky for smaller homes
The Levoit 600S is our top choice for an air purifier that effectively captures allergens in your home, and with good reason. Not only did it perform well in all of our tests, it's also quiet, easy to use, and comes with a range of handy smart features.
What the users say:
The Levoit 600S scores a masive 4.7 out of 5 stars on Amazon, with 83% of users giving it the full 5 stars. Reviewers were impressed with its ability to clean the air of odors and dust. Positive reviews were also gained thanks to the stylish look of the Levoit 600S, but some think it is a little bulky. One user said, "I LOVE the 600S air purifier, it has surpassed my expectations!! Pollen filtered out and the air in the flat is cleaner than outdoor (Paris city center); this machine is a joy to have in the home!" Negative reviews are few and far between, and most cite faults with the VeSync app.
Thanks to its True HEPA H13 filter, this air purifier aced our tests under a number of conditions, removing 99.9% of particles smaller than 0.3 microns at certain times. The air purifier also have the ability to capture some bacteria and viruses, and with an advanced activated carbon, the machine filters volatile organic compounds from the air.
Not only is the Levoit 600S a powerful air purifier, but it also gains points for its discreet design — its toned-up colors and traditional rectangular shape make it easily blend with most home decors. Setting up this appliance is easy thanks to the intuitive controls, and there's plenty of information accessible on the app connected to your purifier, which gives you statistics on historical and current air quality within your home.
On the other hand, the Levoit 600S is quite a bulky machine, so it may not be suitable for tight spaces. It is also relatively expensive — but still more affordable that some of the Dyson and RabbitAir models, for example.

The best budget option

+Charcoal filter to remove odors
-Design won't blend with home interior
If you’re on a budget and need an air purifier to tackle your allergy symptoms, then the GermGuardian AC4825E will be an inexpensive purchase that can go a long way to help you breathe easier.
What the users say:
The Germ Guardian AC4825E has an average score of 4.7 out of five stars from a huge 34,876 reviews gathered on Amazon. Many users said this smaller air purifier was great for everyday use, and helped alleviate allergy symptoms. Other less impressed reviewers said they felt they needed a more complex filtration system.
Complete with a HEPA filter and a charcoal filter to filter odors, this appliance can make your living space a nicer place to be. It’s also ultra-quiet, meaning it can work away in the background without alerting you.
As you might expect with a smaller unit, the coverage of this air purifier is not quite as extensive as bulkier models. It would be suitable to single rooms, rather than expansive spaces, and stands at just 22 inches tall, meaning it won’t be too disruptive to your room’s decor. There are some other handy features too, including a light to indicate a filter change is due and three speeds including an ultra-quiet sleep mode so that you can keep your machine running into the night.
We were impressed by its ability to remove harmful particles in our match and incense tests, especially for its price point. If you want a no-frills, but a very effective air purifier, we’d recommend the GermGuardian.

Air purifier with the lowest energy consumption
Our expert review:

HEPA filter: Yes
Energy star certified: Yes
+ Sleek design, despite size
- Bulky, heavy unit
If you suffer from allergies and need a unit in order to cover larger rooms in your home, then the Blue Pure 211+ is the ideal choice for you.
What the users say:
The Blue Pure 221+ scores an impressive 4.6 out of 5 stars on Amazon, with 79% of users awarding it the full five stars. Those who left positive reviews were impressed by this air purifier's performance, as well its sleek design and ease of use. Some less impressed users commented on the expense of replacing filters, and several negative reviews complain that the higher settings can be too noisy.
While it’s a larger and bulkier model, the outcome is that it can cover rooms up to 600 feet large, which is seriously impressive. Handily though, this increase in coverage doesn’t mean that running the Blue Pure 211+ is going to break the bank. Instead, this air purifier is also economical to run and is available in a range of colors to make it a little easier to camouflage into your home.
The performance of the Blue Pure 211+ in our range of tests proves its place in the top ranks of air purifiers of its kind; it was able to absorb particles in a number of conditions in the most effective way we’ve seen. If you’re a smart home fan then the lack of features with the Blue Pure 211+ might be a little lacking for you, but for simple, straightforward running, this appliance should be an excellent fit.

+Powerful enough to handle peak pollen season
-Can get noisy at high levels
As with any Dyson product, a sleek and well-engineered design was to be expected of the Dyson Purifier Cool.
What the users say:
The Dyson Purifier Cool has an average score of 4.2 out of five stars on Home Depot. Unimpressed reviewers cite problems with the sensors’ readings and high levels of noise when in use. Positive reviews praise the air purifier for its ability to improve the symptoms of allergy sufferers, as well as getting rid of bad smells. Of course, customers also particularly like the integration with smart devices, the auto setting, and the purifier’s cutting-edge design.
This appliance definitely doesn’t disappoint on those grounds, and has a practical edge too, doubling as a cooling fan. Beyond aesthetics, this purifier also performed exceptionally well in our testing protocol, with our tests concluding that it often captured more than 95% of monitored particles when used at its highest setting for at least 30 minutes.
When it comes to assisting with cleansing the air of allergens, the Dyson Purifier Cool aims to pick up microscopic particles smaller than 2.5 microns, including smoke, bacteria, and allergens – shown as PM 2.5. If you want your home to be a relief from allergy symptoms - especially in peak pollen season for example - then another neat trick with the Dyson Purifier Cool is that you can set your machine to start working remotely, all from the comfort of your machine’s app. Though this air purifier might not be within everyone’s price range, it has a lot to deliver, and an eye-catching design to sweeten the deal.

Best for larger rooms
Our expert review:

+Six stage filtration system
+Ability to wall mount
-Not as "whisper quiet" as advertised
-App is tricky to use
If you struggle with allergies and are looking for an inconspicuous air purifier to add to your home, then the Rabbit AirMinus A2 Spa-780N has a design that’s made for sleek, stylish homes.
What the users say:
The Rabbit AirMinus A2 Spa-780N has an average score of 4.7 out of five stars from reviews gathered on the Rabbit Air website. Some unimpressed reviewers complained of a fiddly set up, but many positive reviews praised the capability of this air purifier for cleaning the air in large areas.
Able to be wall mounted or used as a portable purifier, this appliance is impressive on many counts. It has a standard coverage of 815 square feet, which is perfect for larger spaces, and a CADR capable of trapping pollen, dust and smoke in your designated space within that size. It’s crucial when shopping for an air purifier for allergies that you look out for a solid clean air delivery rate (CADR), and this air purifier claims to have high delivery rates with all of those allergens.
When it comes to selecting an air purifier for your home, there’s a number of practical features to think about too. This Rabbit Air AirMinus A2 Spa-780N has been engineered to be ultra quiet, which is bound to be a top consideration for light sleepers. Having said this, we measured 48 decibels on turbo speed, so it's not quite as quiet as advertised. The design of this air purifier means you probably won’t even notice that it’s there (especially with the wall mount option) but you’re bound to feel its benefit when it comes to air quality. In our tests, it removed between 84-90% of particles between 0.3 and 10 microns in size in just 30 minutes.

+ Real-time air quality monitoring
-Quite an investment
The Coway Airmega 250 is a popular air purifier due to its high-end design and claims that it can capture 99.99% of fine airborne particles.
What the users say:
The Coway Airmega 250 has an average score of 4.7 out of five stars from 92 reviews gathered on Amazon. Fans of this air purifier were impressed by the quiet running of this unit, but others were left a little confused by the setup process of this model.
It has a three-stage filtration system, which makes it a good choice for allergy sufferers, and gives you helpful indications of when to change your filters, as well as filters that are in themselves easy to clean. It’s also thorough in its performance, with a capability of covering up to 930 square feet, one of the most impressive coverages we’ve seen.
Although it’s pretty pricey, the Coway Airmega 250 doesn’t have the smart-enabled features you might expect. Despite not being able to control this device via your phone, there are smart features though. We liked that we could set the appliance on a Smart mode that adjusts the fan speed based on the air quality readings, easing the strain on energy bill. Rapid mode is a unique feature of the Coway Airmega 250, which we liked because it helps to quickly clear the air in cases when your air quality turns bad — for our tester, that often happens when she’s searing a steak. Rapid mode circulates the air at maximum power until the air is clean.

-Pricey filter replacements
-Bulky design
When it comes to air purifiers, Turonic may be a new kid on the block — but don’t let that put you off. The Turonic PH950 2-in-1 model may be a strong contender for the title of best mid-range air purifier.
Weighing in at almost 24 lbs, it's definitely not the lightest piece of equipment on the market. It is also bigger and wider than most competitors, so you may need to sacrifice some floor space. But taking into account what the Turonic PH950 can offer, this is not necessarily a deal breaker.
What the users say:
The Turonic PH950 scores 4.3 stars out of 5 on Amazon, with reviewers praising its ease of setup and effectiveness at improving air quality. Negative reviews focus on the high cost of replacement filters.
Indeed, the Turonic PH950 is a powerful 2-in-1 machine combining an air purifier and a humidifier. This complex piece of equipment is equipped with an ionizer, UV-C technology and several different filters designed to neutralize up to 99.98% of unwanted particles as small as 0.1 microns. It also comes with 10 different operating modes, a handy remote control, a designated app, a timer, PM2.5 laser air quality sensor, and a child lock — all for approximately $400 per unit. It may sound like a hefty price tag, but we found the Turonic PH950’s performance to be superb in our tests. And since this piece of equipment is highly energy efficient, it will not rack up your energy bills.
We also found the Turonic PH950 easy to assemble and use. It is equipped with a stylish circular display and easy-to-understand color-coded indicators. The display is also suitable to use in a bedroom at night, as the icons are bright, but not flashy.
The downsides? For a relative beginner, the Turonic PH950 may seem like an overly complicated piece of machinery. Changing a filter in this piece of equipment can also prove quite costly — a price for a single filter pad tends to fall between $45 and $60.

Putting the Vital 200s through its paces in our at-home testing, we found it impressive and efficient at removing particles measuring as small as 0.3 microns. Pet dander, mold, dust and smoke were absorbed while chemicals and odors from everyday household cleaning and cooking were neutralized by the three-stage filtration system. This includes a washable pre-filter, an H13 True HEPA filter and a high-efficiency activated carbon filter.
What the users say:
“Ok, I am a believer now in air purifiers. We originally purchased this as we have new puppies and wanted to help eliminate the slight ‘puppy smell.’ It not only did that but also got rid of the cooked bacon smell after breakfast that previously would tend to linger,” remarked one BestBuy customer. BestBuy users award the Vital 200s a five-star rating.
While the large boxy design may not be suited to users who want a sleek and stylish air purifier, or those with small rooms, the no-frills aesthetic makes the Levoir Vital 200s the perfect choice for most users. While it’s not cheap, it is relatively affordable, and if you value clean indoor air quality, you won’t be disappointed with its performance.
The Levoit Vital 200s offers four fan speeds, three separate modes including pet, auto and sleep mode, and a connected app that allows you to control your air purifier remotely, wherever you are. It also works with Google Assistant and Alexa voice control devices.
The Vesync app is easy to use and allows users to track their real-time air quality data and historical data, revealing peaks in poor air quality over the day and taking the guesswork out of what’s causing bad air quality in your home.

For people with large, airy homes or commercial premises
Our expert review:
Width: 13.6 in

+Great performance in testing
+Easy to set up and use
-Air quality indicator could be better

The Sciaire+ HEPA air purifier by DH Lifelabs is designed to maintain clean and germ-free living spaces efficiently. It utilizes 16 ion generators to bond with airborne particles actively, achieving a 99.99% elimination rate of bacteria and viruses. The 3-in-1 filter system, including pre-filter, HEPA filter, and activated carbon filter, effectively removes particles as small as 0.1 microns, addressing pet dander, pollen, dust, allergens, and volatile organic compounds (VOCs).
What the users say:
The DH Lifelabs Sciaire + HEPA Air Purifier has an impressive average rating of 4.6 out of 5 stars on Amazon, and more than two-thirds of satisfied customers have given it a perfect 5-star rating. Positive reviews praise this air purifier for ease of use and assembly, large design, and glossy screen at the top, even despite its relatively high price tag. One user commented, “First impressions were that this purifier looks superb - a sleek silvery tapered tower design that’s the polar opposite from an industrial box.” Users also enjoy how quiet the purifier is during operation.
The purifier also features a dual air deodorization process, breaking down odors and neutralizing unpleasant smells. It covers areas up to 452 sq. ft., with Wi-Fi connectivity and app control. The design is big, though, measuring 35.4 inches in height and 13.6 inches in diameter. It may be too large for smaller homes. It performed well in our at-home user testing and was super-quiet during operation, even on auto-mode.
With a 4.6 out of 5-star rating on Amazon, users enjoy how easy it is to use and how well it performs. However, they raise concerns about its size being more suited for commercial premises and the potential expense of filter replacements.
Due to its large size, we’d recommend the DH Lifelabs Sciaire+ HEPA Air Purifier for those with spacious homes or commercial spaces. Despite its substantial dimensions, it offers efficient air purification and ease of use, making it a suitable choice for the right environment.
