What do I need to know about air filters for asthma?
If you have asthma symptoms, an air filter or room air cleaner may help you to breathe better. The same is true for those with hay fever (allergic rhinosinusitis) or COPD (emphysema or chronic bronchitis).
If you live with a smoker, an air filter or room air cleaner is likely to be helpful. Almost all room air cleaners efficiently remove smoke from the room (as long as the air filter is large enough, the fan turned on, and the air filter is maintained).
