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 16×25 filter typically measures 15.5 x 24.5. Please measure your current air filter in order to get the exact dimensions.
