Avoid Dust, Dander, and Pollen
Dust mites (really, their droppings) are the most common trigger of allergy and asthma symptoms. These tiny insects live in the dust particles that naturally collect in our homes. Pet—and human—dander (skin cells) and pollen, of course, also are common culprits that trigger allergy and asthma symptoms. The key is to have as few places as possible for particles to collect on, and to keep these places clean.
- Keep windows closed and use air conditioning. Don't use fans, which stir up dust. Also keep the house dry.
- Replace wall-to-wall carpet, if possible. Carpeting traps dust. Flooring like hardwood, tile, and linoleum is better. Use small rugs that can be cleaned easily. If replacing carpet isn't feasible, vacuum it at least weekly. Use a vacuum with double bags or a HEPA (high-efficiency particulate) filter.
- Cover mattresses, box springs, and pillows with plastic cases or special allergen-proof fabric covers.
- Avoid down pillows or comforters.
- Avoid upholstered furniture, which can trap allergens; try to use only wood, plastic, leather, or vinyl furniture that can be wiped clean.
- Replace dust-collecting blinds and long drapes with window shades or washable curtains.
- Wear a mask and gloves when cleaning and vacuuming.
- If you have pets (of course, it's better for you not to have pets), keep them out of the bedroom, since we spend the majority of our time at home in the bedroom. Bathe your pets regularly as well. And keep them off of upholstered furniture.
