Frequently Asked Questions

Q. When a municipality uses chloramine disinfection, which product should be used to obtain better tasting water?

A. For chloramine reduction when pressure drop is a concern with a flow rate, choose CGAC. For a very good general purpose filter that will efficiently remove particulate matter, choose ChlorPlus® blocks. Choose the Big Blue®-sized CRFC product for high-flow applications.

Q. Customers say they've experienced a drop in water pressure after installing filtration cartridges, a concern that worsens in a relatively short period of time. Does PENTEK® offer a cartridge that will last longer than others without causing a drop in pressure?

A. To minimize "plugging" and pressure drop, choose a product from the CFB series manufactured using our Fibredyne™ technology. These cartridges deliver longer effective usage, and cause only a minimal drop in pressure.

Q. Is there a single cartridge that will effectively clean all water?

A. No single cartridge will be effective for all contaminants. All carbon products will remove chlorine taste & odor from water, but health effects depend upon many factors, such as product formulation, flow rate and application. Using the cartridge selection table, the performance data sheets, and a water test (if appropriate), will help in selecting the best product for a user's unique individual needs.

Q. Will a basic, standard diameter ten-inch filter effectively remove chlorine taste & odor from all the water used in a home?

A. A granular radial cartridge (RFC or CRFC) for whole house applications would be a better choice, since it will maximize the number of gallons treated with a minimal effect on pressure drop across the system.

Q. Does PENTEK offer a product that can effectively remove bacteria from well water so it's safe to drink?

A. The PENTEK MG-10MCB cartridge can effectively reduce bacteria and cysts by 99.9999%, creating very safe water for many months, and reducing the need to purchase bottled water.
