Say goodbye to airborne dust, dust mites and  pollen!

Air Sponge frames are constructed of heavy-gauge aluminum and a dust grabbing, charged electrostatic screen.  Each frame is made precisely to your exact filter size.  With Air Sponge's Hinge air filter frame, the front of the frame pops open, so your inserts just drop in.
