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.
Ventilation is important.
