CTO 10 micron Block Carbon replacement filter element for 10" water filters and water filter Reverse Osmosis Units.

Carbon is a substance that has a very long history of being used to absorb impurities & is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 120 acres and can absorb thousands of different chemicals. Activated carbon is carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules.

Activated carbon filtration is very common in a number of home water treatment systems. It can be used as a standalone filter to reduce or eliminate bad tastes and odors, chlorine, and many organic contaminants in municipal (pre-treated or chlorinated) water supplies to produce a significantly improved drinking water. It is also very commonly used as a pre-treatment as part of a reverse osmosis system to reduce many organic contaminants, chlorine, and other items that could foul the reverse osmosis membrane.

These filters are made to the highest specification, and are a direct & suitable replacements for most 10" water filters, and RO Reverse Osmosis water filters.
