What is lurking in the air inside your home?
We're all spending more time indoors, but how clean is the air in your home? We test indoor air quality, as well as the marketing claims and the effectiveness of popular air purifiers. Do these products — which range in price from about $150 to $800 — clean your air?
Watch our investigation Friday at 8 p.m. (8:30 in Newfoundland and Labrador) on CBC-TV and CBC Gem.
