Dust Control Furnace AC Register Air Vent Filters 4" x 10", 48 Pack

Air vent register filters effectively trap the pet hair, dust, dirt, smoke and pollen size particles. They reduce the amount of them from air you breath in your home and reduce the amount of dusting a cleaning you have to do. Maintain clean air and a clean home proactively with these filters. They also, prevent dirt and objects from falling into ducts which saves money getting your ducts cleaned every year. Can be cut to fit standard size vents if needed.
