Exposure to indoor air pollutants can cause respiratory
diseases, including asthma and lung cancer. Pollutants include smoke, pet
radon, mold, cleaning products, and other chemicals.

dander. Don't allow them to sleep in the bedroom with anyone who has
asthma or allergies. If possible, keep them off
carpets and furniture.
Choose window coverings that are easy
to clean, such as wood shades or blinds. Drapes are magnets for dust.
Check houseplants for mold. Repot or move them outside if the
soil contains mold.
Do not allow anyone to smoke in your

Keep bathrooms, kitchen, and

Avoid heating problems
Make sure fuel-burning furnaces, hot water
heaters, and gas ranges are checked every year to ensure air intake and exhaust
systems are adequate. It is best to have your water heater and furnace outside
of your home-for example, in your garage.

Check household furnishings
Many furnishings contain formaldehyde and other
organic compounds. When shopping for new furniture or cabinets, try to buy
those that are made of solid hardwood, not particleboard, which usually has a
wood-veneer finish. The wood veneer may be attached with glue that contains

carpet with tile or wood flooring. If carpeting is necessary, use a product
with a short nap, or use area rugs that can be cleaned regularly.
If you are remodeling, use gypsum board, plaster, or real wood
for walls. Plastic or wood-fiber paneling may emit formaldehyde.
If your house was built
before 1978, the woodwork or other
surfaces may be covered with lead paint. You can have the paint
tested for lead. Do not sand or strip off the lead paint. But you can cover
surfaces with wallpaper or other building material. Call an expert
if you have to remove lead paint.
Be careful with household products
Take care when using
cleaning products, paints, solvents, and pesticides. Try not to use
them inside the house. If you must use them inside, use a fan to
blow strong odors and fumes out of your home. Be aware
that paint can release trace gases for months after you apply it. Try to use
volatile organic compounds (VOCs).
