DESCRIPTION

Product description：

This 20″ filter cartridge combines granular activated carbon (GAC) and compressed carbon block media to enhance chlorine, taste, odor and organic chemical removal. It's ideal for water sources with high chlorine residuals or variable water quality, offering a dual-layer filtration and adsorption design for improved water clarity and safety. OEM/ODM services are available for customization.

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:

Combined GAC + carbon block gives improved adsorption and contaminant removal.
Effectively reduces chlorine, taste, odor and many organic chemicals.
20″ format supports larger volume use and longer service life.
Suitable for varying water quality — more robust filtration performance.
OEM/ODM flexibility supports private-label and custom filtration solutions.

Where Can You Use It?

Municipal tap water filtration where chlorine and organic loads vary
Pre-treatment for central RO or UF systems in buildings
Commercial kitchens and food-service water supply
Custom OEM water filter manufacturing
Water supply for schools or public facilities requiring stable water clarity
