295 x 595mm 100mm (4″) Cardboard Filter

The 295 x 595mm 100mm (4″) Cardboard Filter is a disposable panel air filter with a rigid cardboard frame and pleated media, 100mm (4″) deep. The deep 100mm pleat pack gives a large media area, so it holds significantly more dust and runs longer between changes than a shallower panel filter, as a G4-grade pre-filter in AHU housings.
