The first filter in the Ametek CCF-301 system is a 5 Micron Sediment Pre Filter. The Pre Filter needs changed every 3 - 6 months so order twice as many as the carbon filters. The Ametek CCF-301 chemical contaminant removal system originally came with 2 of the CC-10 filter cartridges, one each in the second and third filter housings. To upgrade the Ametek CCF-301 water filtration system choose one of the following water filter cartridges for the third filter housing.
