How can air filters help prevent asthma?
Can air filters help prevent asthma symptoms? Maybe. Room air cleaners remove small particles that are in the air near the air cleaner. However, room air cleaners don't remove small allergen particles throughout the space, such as the tiny house dust mite feces that surround a pillow when your head hits it (or you turn over in bed). You inhale these allergens before they ever get near the room air cleaner.
