Allergy-Proof Your Environment

Font Size

Medicines help treat allergy symptoms once they strike, but there are several steps you can take to help prevent symptoms altogether. The following recommendations can help you avoid allergy triggers whether you're at home, outdoors, or out on the town.

At Home

  • Keep windows closed and use air conditioning if you're allergic to pollen. Don't use fans since they can stir up dust.
  • Filter the air. Cover air conditioning vents with cheesecloth to help filter pollen and use high efficiency particulate air filters. Clean air filters frequently and air ducts at least once a year.
  • Keep the humidity in your house below 50% to help prevent mold growth.
  • If you have pets, consider keeping them outside or perhaps ask someone else to take care of them. Animal dander and saliva are common allergens for many people. If you must keep your pets indoors, do not allow them in the bedroom and be sure to bathe them often.
  • Avoid areas where molds may collect, including basements, garages, crawl spaces, barns and compost heaps. Have someone else clean these areas often.
  • Install dehumidifiers in basements and other areas of the house where molds tend to collect. Clean these devices every week.
  • Simple mold testing kits are available in big box stores and hardware stores. They are easy to use and will at least tell you if you have a lot of mold as opposed to a minimal amount. If it is a lot, you can pay more attention to getting rid of mold, especially in the rooms you spend the most time in, such as the bedroom.
  • Air out damp clothes and shoes (in the house) before storing.
  • Remove laundry from the washing machine promptly. Don't leave wet clothes in the washer where mold can quickly grow.
  • Wash shower curtains and bathroom tiles with mold-killing solutions.
  • Don't collect too many indoor plants as soil encourages mold growth.
  • Store firewood outside.
  • Use plastic covers for pillows, mattresses and box springs. Avoid overstuffed furniture and down-filled bedding or pillows.
  • Wash your bedding every week in hot water.
  • Don't allow smoking in your house.
  • Wear a mask and gloves when cleaning, vacuuming or painting to limit dust and chemical exposure.
  • Vacuum once or twice a week.
  • Limit throw rugs to reduce dust and mold. If you do have rugs, make sure they are secure and washable.
  • When possible, choose hardwood floors instead of carpeting. If you must have carpeting, choose low-pile material.
  • Avoid dust-collecting Venetian blinds or long drapes. Replace old drapes with window shades instead.
  • Make sure there is an exhaust fan over the stove to remove cooking fumes.
