DESCRIPTION

Product description：

The 20″ CTO block cartridge is designed for whole-house water filtration and utility water systems. With a larger capacity and longer length, it can handle high flow and extended service intervals, making it a cost-effective choice for entire household or small business water treatment setups. It reduces chlorine, taste, odor, and many organics from tap water while protecting downstream appliances and systems.

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:

Larger 20″ size improves dirt and adsorption capacity — longer lifespan.
Good removal efficiency for chlorine, taste, odor and organic chemicals.
Compatible with standard 20″ filter housings used in whole-house systems.
Low pressure drop with stable flow even at higher water demands.
Suitable for pre- or post-RO filtration to extend membrane life.

Where Can You Use It?

Whole-house water filtration in residential buildings
Utility water filtration for small offices or commercial kitchens
Pre-filter stage for industrial RO or UF systems
Water treatment for rental apartments or villas
Replacement cartridge for large water filter housings
