How can air filters help control asthma?
If you or a loved one has asthma symptoms and there's a smoker in your home, an air filter is likely to improve your asthma control. If there is no secondhand smoke in your home, air cleaners may not help your asthma. If you are the one smoking, a room air cleaner will only help the nonsmokers in your home, not you. The bottom line on using air filters to prevent an asthma attack? If you’re a healthy individual living in a relatively unpolluted environment, there's probably no need to spend the money.
