Reduce the number of contaminants, both chemical and biological, in the home. Chemical contaminants include tobacco, cleaning products, paints, pesticides, personal care products and carpets. Get rid of the chemical products that you are no longer using or store them as far from your living space as possible. As much as possible work outside when doing a chemically dependent job. Wherever feasible, choose natural alternatives to household products - vinegar and water as a window cleaner, for example.
Ventilation is important.
But that's just a beginning. There are many other small steps that can be made to improve the indoor air quality. Regular furnace maintenance coupled with filter change is one of them. Since it removes airborne allergens of pet dander, mold and bacteria and micro particles of smoke, viruses and dust, it improves the quality of the indoor air better than any other residential furnace filter. 3M Canada, in wanting to be part of the solution, will continue this important partnership with the Canadian Lung Association to educate people on the importance of indoor air quality.
