DESCRIPTION

Product description：

20″ food-safe CTO carbon block cartridge is ideal for drinking water systems and water dispensers. With 5 micron filtration and high-density carbon adsorption, it removes chlorine, odor, VOCs and improves water taste — suitable for direct potable water supply.

Carbon Block Filter：

Carbon Block also known as CTO Filters, is made from activated carbon. Activated carbon is carbon that has been treated with oxygen to make it porous, allowing for a larger surface are for chemical reactions to occur. The water passes through the filter allowing the organic materials and chlorine to effectivly bond with the carbon molecules, thus removing them from the water.

Carbon Block (CTO) filters effectiveness depends on the flow rate and contact time with the water. If the flow rate is very high their efficiency could drop to as low as 0% but if the flow rate is slow their efficiency can even exceed those of various different carbon forms. It also has a 5 micron filter ability.

Carbon Block is used to absorb natural organic compounds and synthetic organic chemicals which affect the colour, taste and odour in drinking water.

Key Benefits:

Food-grade carbon and housing materials — safe for direct drinking water.
5 micron block filtration ensures sediment and chemical removal for clean taste.
20″ length gives longer service life for continuous use.
Improves water taste and removes chlorine/organic contaminants.
Fits standard 20″ housings for easy installation or retrofit.
