CONTROLLING ALLERGENS IN THE HOME
CRS CONSUMER ARTICLE
Household allergens can cause a variety of symptoms in many people, including
sneezing, watery eyes, coughing, and shortness of breath. Allergens may also be a
contributing cause of asthma, especially in children. However, it is possible to minimize
the effects of such allergens by taking steps to control their presence and dispersal in
the home.
The most common household allergens include dust mites, mold, mildew, pollen, and
pet dander (dried flakes of skin shed by pets, particularly cats and dogs). Effective
control relies on a combination of measures that, when used properly, will reduce the
levels of allergens and allergen exposure.
• Increase ventilation to the home. Opening windows whenever possible promotes
good air exchange and will reduce the concentration of airborne allergens,
especially pet dander.
• Wash bedding and stuffed toys once a week in hot water to control dust mites
and cat allergens in particular.
• Keep pets clean and well groomed to control dander.
• Use mite-resistant mattress covers and pillow covers and wash these frequently.
• Dust and vacuum regularly, and use micro-filtration or HEPA filter vacuum bags.
The jury is still out on whether bag-less vacuum cleaners are more effective in
removing allergens than those that require bags; some studies indicate that
many bag-less vacuums are not sealed tightly enough and can actually make the
problem worse. Wearing a dust mask while dusting and vacuuming is also a
good way to reduce exposure.
• Consider removing wall-to-wall carpeting and replacing them with easily-cleaned
area rugs, particularly in bedrooms.
• Make sure bathrooms, especially those with showers, are well ventilated. Open
the window and use exhaust fans that vent to the outdoors to prevent moisture
buildup, which can encourage mold and mildew growth.
• If possible, reduce indoor humidity to 50% or less by using room dehumidifiers or
the dehumidifier feature available with many central air conditioning systems.
• Clean or replace furnace and central air conditioner filters on a regular basis.
Make sure that air conditioner drain pans are clean and that they allow the water
to drain properly.
Taking these simple steps can mean breathing easy in a healthier, more comfortable
home.
