Carbon Block Cartridge with Polyphosphate, For Calcium and Scale

KleenWater Calcium and Scale Reduction Carbon Block Filter Cartridge

The KleenWater KW2510CB-P 5 micron carbon block cartridge is made in the USA. The carbon ingredient removes chlorine and chemicals from water. Chlorine can dry the skin and may be an irritant to some. Some studies indicate that there are inhalation risks present when showering with chlorinated and chemically treated water. This cartridge can substantially reduce the chlorine and chemical content of water.

This cartridge also contains FDA approved polyphosphate which aids in scale control. This will benefit the shower appearance by reducing hardness build up and protect the shower valve fixture from the harmful effects of scale. The cartridge should be changed every 6 months. The cartridge is rated for up to a 3 gallon per minute flow rate. It is perfectly normal to hear a rattling inside the carbon block cartridge do to the addition of the siliphos spheres.
