ACF Pleated Filter Cartridge
As a professional filter cartridge manufacturer, we produce the ACF pleated filter cartridge to provide stable performance and reliable chlorine reduction for standard 2.5×10″ water filtration systems. This product is designed as a direct replacement for the second-stage filter in many domestic and commercial units.
Manufactured with Activated Carbon Fiber
We use high-quality activated carbon fiber (ACF) as the filtration media. ACF has a larger surface area and faster adsorption speed compared with traditional carbon block or granular carbon. This gives the filter strong capabilities in removing chlorine, improving taste, and reducing organic compounds.
Pleated Carbon Fiber Structure
The water filter cartridge is formed by pleating carbon fiber. This structure increases the effective filtration area and supports higher flow rates. It also helps extend the service life of the filter. Our pleating process ensures uniform folds and consistent thickness.

Factory-Made Flat End Caps & EPDM Seal
Both ends use flat-style end caps for stable installation.
We apply EPDM O-rings to ensure reliable sealing performance in standard 2.5×10″ filter housings.
Standard 2.5×10″ Compatibility
The size is fully compatible with most 2.5×10 inch filter housings in the market. It is suitable as a second-stage ACF replacement filter in under-sink RO pre-treatment, countertop units, and other point-of-use systems.
