These filters are rolled to our specifications by Thailand Manufacturers that have been in the industry for more than 30 years. This is TRADE QUALITY 100% COCONUT CARBON. These are the same manufacturers that supply Europe and the US.

As a rule, it is difficult to find 100% coconut carbon filters. Most lower-priced filters on the market are a blend of coconut carbon and coal-based carbon. The problem with coal-based carbon is that it has a shorter life and often results in a less palatable flavor.

We use this 100% coconut carbon filter in all of our pre-assembled kits. These are top-of-the-range HIGH-QUALITY coconut carbon block filters that are ideal for taste and odour issues, and perfect for total extraction of town water chemicals.

The perfect carbon block filter is made from 100% Coconut Shell Carbon, which creates what many believe to be the sweetest tasting water. The unique pore structure of this carbon is well suited for chemical absorption, including VOC’s, while reducing chlorine and chemicals that contribute to taste and odour.
