January 31, 2013 (San Diego) -- Dear EarthTalk: My family has bad allergies and I’d like to improve our indoor air quality. What are some steps I should take?
-- Marcia Lane, Scranton, PA
Even for those of us without allergies, poor indoor air quality is an often overlooked health issue. Recent research has shown that the air inside some buildings can be more polluted than the outdoor air in the most industrialized of cities. And since many of us spend some 90 percent of our time indoors, cleaning the air where we live and work might be one of the most important things we can do for our health.
