This popular size 1.5 Cu. Ft. backwashing whole house carbon block filter system has a peak flow rate of up to 8 GPM, and is ideal for a family of 4 or 5 people. Premium Catalytic Coconut Shell Granular Activated Carbon makes up the media bed of our systems. A large amount of this high-grade carbon is used to provide longer contact time and better removal rates for more difficult contaminants.

  When it comes to carbon filters, bigger is better!

A larger media bed provides longer retention time with the water and the media. Carbon can reduce hundreds of chemical contaminants, but the most difficult chemicals require longer contact time for effective reduction. Larger systems do a better job of chemical contaminant removal than smaller systems. These difficult to remove chemical contaminants are also removed more effectively at low flow rates.

H2O offers many sizes of Whole House Filters. We’re happy to help you size the system for your needs, based on the size of your home and family. Beware of competitors offering “One size fits all” systems.

Bigger is Better Whole House Carbon Systems

H2O’s Whole House Systems provide a large bed of premium Catalytic Carbon Media that is time tested to be effective for years of performance. Catalytic Carbon is Granular Activated Carbon that is further processed to increase catalytic reactivity. The resulting carbon media produces much higher chlorine capacities and much better removal rates for Chloramine and Hydrogen Sulfide.
