The Right Filter Company Right Filter, Right Service, Right Value!

These panel filters are rigidly constructed using a progressively dense fiberglass or Polystrand media to maximize dust holding capacity. Two metal grids are thermally bonded to the internal sides of a heavy-duty one-piece craftboard frame.  Glasfloss disposable panel filters are available in many standard and special sizes.   Caution:  Most air filters are stamped with a size that is NOT the actual dimension of the filter.  Example: a 16x25 filter typically measures 15.5 x 24.5.   Please measure your current air filter in order to get the exact dimensions
