DESCRIPTION

Product description：

This 20″ CTO carbon block cartridge delivers reliable 5 micron filtration and carbon adsorption, making it ideal as pre-filter for RO systems or as main filter in whole-house water treatment setups. It effectively reduces chlorine, taste, odor, and organic contaminants while ensuring stable flow across large demand.

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:

5 micron nominal rating balances filtration precision and flow.
Effective removal of chlorine, tastes, odors and many organics.
Compatible with standard 20″ filter housings — easy integration.
Low pressure drop ensures consistent flow and reliable performance.
Extends longevity and effectiveness of downstream RO membranes.

Where Can You Use It?

As pre-filter in residential or commercial RO systems
Whole-house water filtration systems
Apartment complexes or multi-unit buildings water supply
Utility water treatment for offices or small factories
Replacement filter supply for service providers
