While it won't necessarily make your allergies go away, an air purifier can help with symptoms or prevent them from getting worse, according to the American Academy of Allergy, Asthma & Immunology (AAAAI).

When you go to shop, it's a wise idea to zero in on air purifiers with HEPA (which stands for high-efficiency particulate air) filters, the AAAAI notes. These filters are extremely efficient at stripping the air of contaminants and circulate the air in a room multiple times an hour, trapping particles at each pass. (Asthma sufferers: Skip ionizer air purifiers, which use an electric field to capture allergens, as they can generate ozone and potentially worsen asthma symptoms.)

Beyond that, choosing the air cleaner best suited for you really comes down to personal preference, and you may want to consider other factors like size, sound, style, and price point when you're buying.
