Keep your fume hoods properly maintained and ensure safe operation with Air Science USA's Purair 5 Accessories. Choose from a general purpose filter, acid filter, HEPA filter, replacement prefilter packs or replacement trays.
Air Science USA recommends you replace filters on a regular basis. The fume hood units take at least one main filter and one prefilter for each blue filter door. Look in the filter window to determine the main filter part number.
