How to Reduce Pet Allergens at Home
If you have forced-air heating and air conditioning, closing air registers may reduce the amount of animal dander that circulates through your home. If closing all of the registers isn’t practical, try closing those in the rooms where asthmatic or allergic individuals spend the most time (especially bedrooms).
Replacing the filter in your furnace or air conditioner with a HEPA filter and/or purchasing a room air cleaner may also help. Studies on the effectiveness of these methods have been inconclusive, however. (See our air cleaner buying guide for more information.)
