Air cleaner systems use filters and sometimes ionization to pull dust, pollen, smoke, and pet dander out of the air in a room. I've noticed mine makes a big difference during allergy season, especially when I remember to change the HEPA filter every few months. They're not magic, but they do cut down on the visible dust settling on surfaces and help with musty smells in basements or stuffy bedrooms.
