Should I use an air filter in my home?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Home air filters sound like they'd be the best things for your lungs since snorkeling tubes. After all, when used and maintained properly, they can filter allergens out of the air.

Unfortunately, many people don't see big benefits after bringing an air filter home. Why? The primary reason isn't a mechanical malfunction, but an owner malfunction. Most people don't service the air filters regularly, so they're not that effective. They don't clean or change components as the directions recommend. If you stick to regular maintenance, however, air filters can be useful for taking allergens out of the air.
