AstroCel® I
Extend AstroCel® Life with Prefilters
No HEPA filter installation should ever be operated without prefilters.
AAF has a broader selection of prefilters than any other manufacturer
– from roughing filters, to automatic roll filters, to pleated filters, to
extended surface filters. AAF strongly recommends two stages of
prefilters in front of HEPA filter installations.
AAF tests have shown that prefilters greatly extend the life of HEPA
filters. The higher the efficiency of the prefilters, the longer the life of
the AstroCel filters. MERV 15 filters can extend HEPA filter life nearly
nine times.
