Carbon Water Filter Replacement – Coconut Shell Activated Carbon Filter Cartridges

Improve Water Quality with Premium Carbon Filter Replacements

Our carbon water filter replacements are designed to improve the taste, smell, and purity of drinking water by removing chlorine, volatile organic compounds (VOCs), and other harmful impurities. Made from 100% coconut shell activated carbon, these filters are ideal for residential and commercial under-sink water filtration systems.

For optimal performance, we recommend replacing the carbon filter cartridge every 6 months or after 2,000 liters of water usage.

Key Features

100% Coconut Shell Activated Carbon

Laboratory vacuum-heated and steam-activated for maximum adsorption power

Certified Quality Materials

All materials meet NSF and WRAS standards for safety and performance

High Filtration Accuracy

Granular activated carbon (0.8–2 microns); carbon block filters offer 8–20x larger filtration area than PP cotton

Easy Replacement

Simple installation-no professional help required

Extended Filter System Lifespan

Regular replacements protect and extend your water filtration system's life

Product Description

Our carbon water filters play a crucial role in water purification by removing chemicals and organic compounds like chlorine, pesticides, chloramine, and bad odors. The activated carbon is made from clean coconut husks, carbonized at 300–500°C, and activated with high-temperature steam (850–950°C) to increase its porosity and surface area for superior absorption.

Each filter undergoes a strict production process: carbonization, activation, rinsing, drying, and screening. This ensures every cartridge delivers consistent, high-quality filtration for clean and great-tasting water.

CTO Carbon Block Filter Cartridges

Our CTO carbon block filters are manufactured using advanced sintering molding technology. Made with top-grade activated carbon and SGS-approved raw materials, these cartridges offer:

Strong chlorine and chemical removal
Fine sediment filtration
High structural strength and long-lasting performance

Perfect for use in residential water filters, under-sink systems, and commercial applications.

When to Replace?

Every 6 months
Or after 2,000 liters of filtered water (whichever comes first)

Keeping up with regular replacements ensures optimal filtration performance, better-tasting water, and longer system life.

FAQ - Carbon Water Filter Replacement

Q: What is a CTO carbon filter?

A: A CTO carbon filter element is also called a sintered activated carbon filter element or a Carbon rod filter. The carbon rod filter element is a new type of depth filter element. It is made of high-quality activated carbon as a raw material, and its structure is composed of low-hot-melt adhesive. It is continuously extruded, sintered, and solidified at low temperatures to form a specific strength.
Features
High filtration precision, small pressure loss, large flow, large dirt holding capacity, long service life, non-toxic, odourless, and no secondary pollution;
Strong adsorption capacity;
High mechanical strength;
Uniform density, long life, and good dechlorination effect

Q: What does a CTO filter remove?

A: The CTO filter element has excellent granular activated carbon adsorption performance and effectively overcomes the carbon powder leakage defect when using all activated carbon filters. It has the precision filtration characteristics of tubular elements and can effectively remove organic matter, particles, rust, residual chlorine, odour, etc., in the liquid.

Q: How often do you change a CTO filter?

A: The filter cartridge must be changed every 6 months or 2000L. It is convenient and easy to replace the filter element; you can do it at home.
