How can HEPA filters help relieve allergy symptoms?

ANSWER

Studies are mixed about whether air filters help with allergy symptoms. That’s because far more allergens rest on surfaces like rugs, furniture, and countertops than simply hang in the air. So cleaning is an important step in controlling your allergy and asthma triggers. If you buy an air filter, make sure it's a HEPA filter. These capture fine, pollen-sized particles. It's a good idea to get a vacuum cleaner with a HEPA filter, too. Regular vacuums can blow allergens back into the air.
