Our homes are loaded with dust mites, pet dander, pollen, and other indoor air pollutants. To be clear, I’m not a doctor, but I don’t think I need a degree to know that poor ventilation—combined with the use of household chemicals, gas-burning appliances, and tobacco products—all can contribute to less-than-healthy indoor air. Worse, once airborne, these irritants can irritate asthma and allergies, according to the CDC and the Asthma and Allergy Foundation of America. allergies and asthma.

Air purifiers can reduce the number of airborne pollutants in a home so the whole family can breathe more easily.

How We Chose the Best Air Purifier for Allergies

Those who suffer from allergies know that the right air purifier can ease respiratory problems while creating peace of mind. Selections for the best air purifiers for allergies depended upon their filtration type, square feet covered, noise level, airflow and filtration settings, and added special features included by select brands.

We researched the most sought-after air filtration systems in their respective categories and discovered that activated-carbon, UV, and HEPA air purifiers were among the most popular filtration types on the market. Not only do these types reduce the dust, pollen, and volatile organic compounds in your home’s air, but select models are also capable of reducing odors and eliminating toxic particles of 0.1 microns in size.

With this efficiency, keep in mind that many of the above picks are made for a certain size of space, ranging from 185 to 1,060 square feet depending upon where filtration is needed. Most also come with noise levels under 59 decibels (which is the volume of a typical conversation) and as low as 17 decibels (which is nearly silent). For added convenience, many air purifiers come with multiple modes or settings including an automatic or night mode.

Finally, some of the above air purifiers are made with multistep filtration, are compatible with mobile apps, have built-in air pollution sensors, or are portable air cleaners that can be moved from room to room.
