5 Best Smart Air Purifiers for Allergies

When the indoor air quality of your home is not perfect, investing in an air purifier is the next best solution. These devices remove harmful airborne particles and eliminate pet dander and floating dust particles from the air, which should help your allergies. Could you add smart features to these already cool home appliances? Well, that’s what we will discuss in this post today as we line up our recommendations for the best smart air purifiers for allergies.


But before we go further, let us emphasize that air purifiers can only deal with certain allergens. For example, most air purifiers can counter pet dander and floating dust particles and remove them from the air. However, most purifiers can’t counter allergens like pollen or dust mites since these are heavy and do not float on air.

That said, air purifiers are the perfect shield from common pollutants and allergens and provide an extra layer of protection.

So, let’s check out some of the best smart air purifiers for allergies. But first,

1. Levoit Core 400S

  • Coverage: 403 sq. ft | HEPA: Yes
  • App control: VeSync Link app, Google Assistant, Amazon Alexa

The Levoit Core 400S is one of the affordable air purifiers for medium to standard-sized rooms. This simple air purifier can cover a room of around 400 sq. ft. It’s compatible with Amazon Alexa and Google Assistant, which allows you to control the device via voice commands. It bundles a three-layer filtration process, including a pre-filter, a carbon layer, and an H13 True HEPA filter. These filters can counter dust, floating lint, smoke, and microscopic dust.

Users have praised this air purifier for helping with their allergies by keeping the air clear of dust and pet danders. It isn’t noisy, and as long as you keep it running, the air should be clear.

It has a handy LED display that shows the amount of impurity in the air. And you can turn off the display or lock it through simple voice commands, once you connect the purifier to the smart assistant of your choice. The smart features of this air purifier for allergies may not have as many features as some smart home products, but you get the flexibility of controlling some features via the companion app on your smartphone. For instance, you can create schedules on the app to turn on/off the device.

This Levoit Core 400S is perfect for slightly bigger rooms, and its effective performance and easy-to-use nature have made it a popular choice. It has more than 10,000 user reviews on Amazon. The best part is that the built-in filter lasts about a year before needing a replacement.

In short, if you want the best deal for your money without compromising on performance, the Levoit Core 400S is a good pick.

2. Coway Airmega AP-1512HHS

  • Coverage: 788 sq. ft | HEPA: Yes
  • App control: IoCare mobile app and Amazon Alexa

If you are not satisfied with the conventional design of the Core 400S, you should check out the Coway Airmega AP-1512HHS. This Coway air purifier looks like a giant iPod nano. And despite the modern look, it doesn’t have a high price tag. And its reliable and effective performance separates it from other devices in the same price bracket.

The Coway AP-1512HH comes with three filters: a pre-filter, a deodorizer, and a GreenHEPA filter. And it’s the latter responsible for countering air pollutants like fine dust, smoke, and other small airborne particles. It can clear up to 99.97% of airborne particles if we talk numbers. On the other hand, the pre-filter removes mold, pet dander, and floating human hair.

It’s compatible with Alexa and the in-house IoCare app and connects via Wi-Fi and not Bluetooth. As long as you have a strong Wi-Fi network within your house, the odds are that you will be able to control the air purifier through voice commands or the smartphone app. The smart controls are not exhaustive. You can control the display, switch it on/off with voice commands or check the filter health. And that’s about it.

The Coway AP-1512HH is a quiet machine and doesn’t cause a stir even at full speed. It comes with a super handy eco mode which runs the device in energy-saving mode while still clearing the air around.

This Coway purifier is well-liked by its user base and has more than 19,000 user ratings on Amazon. It works efficiently to clean the air around the room, and many users have noticed a stark difference in their allergic reactions, especially the ones with pets.

3. Honeywell Air Purifier HPA8350B

  • Coverage: 465 sq. ft | HEPA: Yes
  • App control: IoCare mobile app and Amazon Alexa

The Honeywell Air Purifier HPA8350B is a smart purifier and can fight everything from 0.3-micron particles, and mold to VOCs, gases, and bad odors. The True HEPA filter can counter bacteria and viruses. Interestingly, the HPA8350B has Bluetooth connectivity and is not compatible with Amazon Alexa or Google Assistant.

That said, you can control the purifier if you are around it. If we talk numbers, you can access the purifier’s controls as long as you are in a straight line of sight of 30ft. Surprisingly, the app displays the status of your proximity to the purifier. You can now switch to Auto mode or switch it off via your phone.

It’s worth noting that this smart Honeywell Air Purifier HPA8350B is one of the most reliable performers out there. The combination of three filters ensures that the air around you is clean and free from pollutants and allergens like pollen, pet dander, and floating dust particles. It has a dedicated Allergen Alert setting that alerts you to pollen and mold levels in the room.

The folks at Breathe Quality ran this device in a 200 sq. ft room for an hour and it could clean 99.95% of the air. For the record, this Honeywell smart purifier can cover bigger rooms up to 465 sq ft.

The Honeywell HPA8350B is not without its share of limitations. For one, it isn’t quiet. Running at full speed can be distracting, especially if you are a light sleeper.

4. Dyson Cool TP07 Purifier

  • Coverage: 800 sq. ft | HEPA: Yes
  • App control: Dyson Link and Google Assistant

Dyson has made a good name for its innovative designs, and the Cool TP07 purifier is one of the newest upgrades to its tall air purifiers. Its highlight is the enclosed design which ensures that it delivers purified air around. The TP07 bundles a combination of a HEPA filter and a Carbon filter. And this combination eliminates both pollutants and bad odors. It rotates up to 350 degrees, making it apt for bigger rooms. And yeah, the filters are easy to switch.

This is a smart purifier and brings Wi-Fi connectivity to the table. If the Wi-Fi connection is strong, you can control it remotely, whether you are in another corner of your house or from your office.

The Dyson Link app lets you control the fan speed, switch fan modes or even turn it on/off. And that’s not all. You can also see the air statistics of the air quality around it. Additionally, you can add voice commands to the mix by connecting it to Google Assistant.

The filters do a neat job of ridding the air of dangerous pollutants. Dyson rates the HEPA filter of clearing up to 99.95% of microns up to 0.1 microns. And the carbon layer is responsible for countering dangerous VOCs, bad odors, and other gases from the air. The air purifier takes 15 to 20 minutes to clean the air in a room and it works best in auto mode.

But, the Dyson Cool TP07 purifier is one of the more expensive products. You will have to spend a considerable sum to get it; the same is true of the replacement filters.

That said, you get a slew of features. For example, it can rotate in any direction of your choice, and the smartphone app opens the door to many features. More importantly, it’s one of the best products to keep indoor air free from allergens and pollutants.

5. Coway Airmega 400S

  • Coverage: 1,560 sq. ft | HEPA: Yes
  • App control: IoCare mobile app and Amazon Alexa

Lastly, we have the Coway Airmega 400S on our list. Like the Dyson smart purifier above, this is one of the premium air purifiers.  And if you or one of your house remembers to have a sensitive nose, this one is your best pick. The highlight of this device is its unconventional design and the huge coverage (almost double of the TP07). As you may have suspected, its filters do an excellent job of eliminating smoke, pollen, and dust.

The folks at Gear Lab tested this smart purifier and brought down the concentration of smoke and other particulates from 1,500 to 220 in 30 minutes flat. And it took another 30 minutes to bring it down to 2. Now, that’s impressive.

This purifier is quiet, and even in the highest mode, you are unlikely to be distracted by the sound. However, a switch to Auto Mode will do the trick if you are a light sleeper. While it’s not compatible with Amazon Alexa or Google Assistant, the companion app helps you switch modes. However, the built-in smart feature trumps the app control since the air purifier can turn itself on/off depending on the air quality.

It can cover a large area of 1,560 sq. ft. If you want the best purifier to tackle your allergy to pet dander or floating dust (among others), you can’t go wrong with this one.

Purify the Air Around

These were some of the smart air purifiers for allergies. Again, we’d like to emphasize that these handy devices can only tackle some kinds of allergies. Air purifiers usually consume little power, and even if you run them 24×7, you shouldn’t see a huge surge in your utility bill.
