Excelpure 20" x 4.5" Big Blue GAC Coconut Carbon Filter | Pack of 6 Filters
Excelpure Big Blue GAC type cartridges are designed to allow maximum contact time between the water and the carbon media. They allow water to enter at one end and to pass through the entire length of the carbon bed, exiting the other end of the cartridge and ensuring maximum absorption. As the water exits the cartridge, a 5 micron post filter reduces carbon fines and other suspended particles from the filtered water.
Fits all 20" BB or Big Blue filter housings that accept 4-1/2" diameter cartridges.
