Best Air Purifiers for Allergies Reviewed 2017 – Buyer’s Guide


Springtime is nearly here, but for many, the blooming of flowers and spring cleaning is pure terror. There’s this enemy called allergies. If you’re an average person, then you probably have them. Common allergens during spring (and even fall) include pollen and grass. What makes pollen tricky is that it can travel great distances so you may not even be allergic to any plants in your area.

Maybe you don’t have seasonal allergies, but another allergen triggers your system: pet dander. Whether you’re an animal lover or not, pet dander can also prompt your body to produce histamines. The itchy and runny nose, watery eyes, and sneezing bursts can make it difficult to function. All too often, it’s just plain annoying. Perhaps a dose of anti-histamines helps you. But if you’re looking for something more long-term that doesn’t involve medication, then it’s probably time for you to give air purifiers for allergies a shot [1].

Many allergists and allergy sufferers swear by improving air quality with purifiers. If you haven’t considered buying one, we’re here to help. We’ve narrowed down some of the best air purifiers to keep your allergies at bay.

Honeywell HPA300 True HEPA Allergen Remover

Honeywell is a trusted name for household appliances. They engineer a lot of devices from the big stuff (they make aerospace products!) to the smaller stuff you find in your home. From this reliable brand comes an efficient air purifier recommended by doctors, as the company claims. Let’s look under the hood to see what’s in it.

The Honeywell HPA300 True HEPA Allergen Remover follows HEPA standards—it filters out 99.97% of particles that are 0.3 microns in size. These particles include smoke (efficiently filtered out with their activated carbon pre-filter) and most of the dreaded allergens: dust, pollen, pet dander, and even mold. The multi-purpose purifier covers all the bases. Honeywell claims that the HPA300 can clean the air in rooms up to 5 times an hour. That’s actually a pretty good number. This is backed up by their Association of Home Appliance Manufacturers (AHAM) for Clean Air Delivery Rate (CADR) Performance guarantee.

What is CADR?

This is the best measure for the purifier’s cleaning capacity. The higher the CADR, the bigger the room it can clean regardless of what the company lists as the room capacity. To know how much space the purifier can clean out, multiply the CADR by 1.5 (sq. ft.). So if we take the HPA300’s CADR (300) and multiply it by 1.5. sq. ft., you get 450 sq. ft. of area effectively cleaned by the purifier.

The HPA300 Allergen Remover is suited for medium to large rooms, around 465 sq. ft. in as listed by Honeywell. But again, given the CADR, it’s more like 450 sq. ft. However, it’s still perfect for bedrooms, living areas, or any room in the house where your allergens lurk. It will still work well in larger rooms, but it will just take some more time to clean the air. You can also rest assured that this allergen remover does not give you harmful respiratory irritants like ozone.

The electronic controls are a breeze to use. You can choose from 3 air cleaning levels: General, Germ, and Allergen. There’s also a Turbo Cleaning option. You can set the timer in the purifier to make it run for 2, 4, or 8 hours. It fits nicely in any area, and it is quiet enough for you to enjoy what you’re watching on television, or for when you sleep. The loudest setting would be the Turbo mode. Generally, it’s nonintrusive and highly effective. Once your filters need replacing, you will get a reminder from the purifier. At less than $200, this allergy remover is a bargain. Honeywell offers a 5-year limited warranty.



Honeywell HPA200 and HPA100 True HEPA Allergen Removers

The HPA300’s smaller cousins, the HPA200 and HPA100 are also worth noting if you want a smaller or mid-size allergy remover. They have the exact same features as the HPA300 but since they’re smaller, they’re also slightly cheaper. The HPA200 is best for rooms over 300 sq. ft. in size and the HPA100 for half that area—around 155 sq. ft. The HPA100 is on sale for less than $100.


Whirlpool Whispure Air Purifier AP51030K

Honeywell HPA300’s worthy opponent would be the Whirlpool Whispure Air Purifier. Remember what we said about CADR and room space? For the Whirpool Whispure Air Purifier, its CADR is 315. If you multiply that by 1.5, you get 472.5 sq. ft. When it comes to cleaning capacity, it seems that the difference between the HPA300 and the Whispure is minor. The HPA300 is $100 cheaper than the Whispure but with comparable features.

Whirpool’s purifier cleans out air at about the same rate as the HPA300 (5 times per hour versus Whispure’s 4.8 times. You just round it up). Whispure also makes use of True HEPA filters but it does have four fan speeds on top of its sleep and turbo modes. The HPA300 only has three plus the turbo mode. Whispure also blows out cool air. The Whispure overall is also reliable, durable, and effectively rids the air of allergens as well as unpleasant odors. Get this if you have extra cash to spare; note that Whirlpool’s filters can also be pricey even if might not have to change it as often as the HPA300. Otherwise, the HPA300 is a good choice for your allergen removal needs and your budget, too.




Don’t settle for daily doses of Claritin when you can minimize your allergy attacks for longer with an air purifier. It catches allergens that you can’t see such as pollen and pet dander. There are other ways for you to reduce your allergies: vacuuming regularly, cleaning up sheets and curtains, and getting allergy medicine. Add air purifiers to your allergy treatment. Buy one, let it run, and see a major improvement in your air quality and breathing.
