HAF filters from 3M employ three critical technologies to help protect your equipment. First, HAF filters have an open channel structure that maximizes airflow while providing plenty of surface area for collecting airborne particles. Second, the filters employ an electrostatic charge to attract, capture and retain more material – more than twice as much as washable foam.* And third, HAF filters include an antimicrobial agent that prevents mold from growing on its surface.

These features mean HAF filters provide efficient, highly effective filtration and a long service life. In fact, HAF filters can be vacuumed and reused up to three times before they need to be replaced.
