We take 24,000 breaths a day and breathe in about 13 kg of air. Though occasional hazards like smog and visible air pollution catches our attention, the issue of everyday indoor air quality often goes unnoticed –especially indoors at our homes or places of work. Few realize that indoor air can be 2-5 times more polluted than outdoor air.
Also, today’s energy-efficient homes tend to be air tight ,staying warm during the winter and cool during the summer. Unfortunately , the house isn’t allowed to breathe and open windows are not always a good option.
