The pre-loaded filter/cassettes are packaged 50 per box. They have an effective filtration area of 820 square mm.

Two-piece and Three-piece 37mm filter cassette bodies without filters or support pads are also available separately.  The 37mm cassettes are made of crystal clear styrene and seal tightly.
