There are several low-to-no-cost steps you can take to improve the indoor air quality in your home based on three best practice strategies of: controlling the sources of pollution; insuring there is adequate ventilation; and, using supplemental air cleaning and filtration. It is also important to control moisture and keep humidity below 60% (ideally, 30-50%).
