POST FILTER is a filter made using a unique combination of ion exchange resin and granular activated carbon from coconut shells.

A water filter made using a combination of ion exchange resin and granular activated carbon from coconut shells is one of the most effective ways to purify and improve the taste of water. These two materials were chosen because they mutually enhance the filtration efficiency.

An ion exchange resin is a material that has the ability to remove heavy metals from water, such as lead, iron and copper. When water passes through an ion exchange resin, it passes through a layer of cationic (positively charged) and anionic (negatively charged) resins that attract and retain heavy metals.

Granular activated carbon from coconut shells is a material that can remove taste, odor and chemical contaminants from water, such as chlorine, pesticides and pharmaceuticals. Activated carbon is a very porous material that has a very large surface area for adsorbing contaminants. As water passes through the activated carbon, the contaminants are adsorbed to the material and remain there.

The combination of ion exchange resin and granular activated carbon from coconut shells produces a very effective water filter that can purify water from many types of contaminants. Such a filter can be used in homes to improve the quality of drinking water.<<<
