Residential Chlorine Cartridge Filters



Cartridge-style whole house filters for city water have many advantages.  They install easily without need for a drain connection and electricity, they are compact and can be wall mounted, they require little upkeep,  and they are very effective.

Below are specially priced cartridge-style whole house  filters designed for city homes whose water supplier uses chlorine (rather than chloramine).  The chloramine version of the same filters are also available. The chlorine filters on this page  use the exceptional Pentek Radial Flow Carbon Filter.  This unique cartridge offers long life, excellent taste/odor performance, and almost no pressure loss.  The radial flow granular style of the RFC20BB restricts flow less than 1 psi at 4 gallons per minute, a fraction of the pressure drop from comparable carbon block filters.  The filter uses powdered carbon that is held in place by a uniquely designed cartridge that eliminates the need for the plastic binders used in carbon block filters.

These units cost a bit more than our standard carbon block whole house units, but their free-flowing performance makes them worth the added expense.

The package systems we’ve put together include a filter wrench, housings, extra O Rings,  brackets, and cartridges.  All housings have 1″ ports (3/4″ or 1.5″ available upon request).  All housings, both 20″ and 10″,  are tough, reliable Pentek “Big Blue.”  All housing packages include mounting screws, heavy duty metal brackets, and one extra housing O Ring.

These systems are designed for parallel installation for larger homes to assure minimal pressure drop and optimal chenical/chlorine performance. See the reference pages listed below for installation pictures. Note that all carbon filters are 20″ and all sediment filters are 10″. The housing caps and brackets are identical for easy installation.

Whole house cartridge filters offer many advantages as compared with tank-style filters.  They install easily (no drain connection and no electricity needed). They are reliable, simple, easily serviced units with a very long lifespan. As compared with backwashing filters, these compact whole house carbon units save hundreds of gallons of water per year because no backwash is needed.

The RFC20 is a NSF-42 certified cartridge with a manufacturer’s rating for 70,000 gallons of chlorine removal @ 4 gpm. PSI drop at 4 gpm is only 0.9 psi. (The cartridge will support a higher service flow. See sizing notes below.)
