11 Ways to Improve Your Home’s Air Quality

Clean Sweep

Though it's tempting to put off chores, it's important to clean regularly to reduce allergens and irritants. Dust with a damp cloth rather than a feather duster -- and don't forget hard-to-reach areas such as ceiling fans and the top of the refrigerator.

To avoid potentially harmful vapors, purchase nontoxic, nonaerosol, unscented cleaning products (or make your own using household products). And use a vacuum cleaner with a HEPA filter for the best results.
