How to choose and maintain water filter cartridges

Cartridges are the heart beat of water filter systems. Water filter cartridges are mainly responsible for removing the impurities from the water. The impurities such as chemicals, particulates, phosphates, micro-organism etc., tend to stick on to the cartridge thus reducing its efficiency. The result is lesser water flow from the filter to the container. Drinking water filters demand more careful choice and maintenance since it interferes with your family's safety and health.

But now they are made of MCB –modified carbon block and also include KDF-55D which contain zinc and carbon that inhibits the growth of bacteria in the cartridge. Beware of any other combination of materials used in your cartridge as they might harm you too. It removes a wide range of impurities and also enhances the taste of water.
