Whole House Replacement Carbon Filter Cartridge 20" x 4.5"
 
Carbon block filters are made from finely ground activated carbon particles. They have been bonded together to create a uniform profile with high kinetic efficiency and superior adsorptive power. Many carbon block filters and cartridge elements flow in a radial direction, from outside to in. This results in lower pressure drop and higher dirt holding power.
 
A carbon block filter is made entirely from approved materials and can be used for both residential point-of use water filtration as well as commercial and food service applications. 
 
The carbon block filters we offer are made from high-purity activated carbon. They can be used in most household and commercial buildings.
