Do Air Cleaners Reduce Dusting?

An effective air cleaner removes large and small particles from the air in a single room. Within that space, it can relieve allergy or asthma symptoms and even reduce smoke and cooking odors. But don’t expect it to relieve you of dusting duty. Air cleaners are sized to filter a small area, so only a small portion of the airborne dust in your home will ever reach the unit. For air cleaners to have a real effect on overall dust levels, you would need one unit in every room.
