The American Lung Association says these steps will reduce indoor air pollution:
* Basement: Keep humidity levels below 50 percent. Add an air cleaning filter to the furnace or central air conditioning unit. Change the filter every three months.
* Living room: Wipe off items on shelves and tables at least every two weeks to reduce dust and pollen.
* Install a ventilation system to remove emissions of gases.
* Bedroom: Wash bed linens in hot (130 degree) water at least weekly to reduce exposure to dust mites.
* Bathroom: Avoid moisture buildup by running the exhaust fan frequently or cracking a window.
