CRYSTAL QUEST WATER FILTER REPLACEMENT SET FOR TRIPLE 20 WHOLE HOUSE WATER SYSTEM. Water Travels Through 8 Stages of Filtration. Stage 1 – Water flows through a 20 sediment cartridge that removes sediment, silt, sand and dirt. Stage 2 – Water flows through a one-micron filter pad which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter. Stage 3 – Water passes through coconut shell granulated activated carbon (Arsenic-Free GAC).
