Replacement Under Sink Water Filter Cartridges with PP Pleated Media and ACF

Our Replacement under sink Water Filter Cartridges are engineered for household and commercial drinking water systems that require efficient sediment filtration and fast chlorine adsorption. This 2.5″ x 10″ composite filter combines PP pleated media, activated carbon fiber (ACF), and a durable PP melt-blown support core, delivering stable performance and long-lasting water purification.

Composite Structure for Reliable Filtration

PP Mesh Sleeve for Outer Stability

The outer PP mesh secures and stabilizes the pleated PP layer, helping maintain its shape and filtration area during high flow.

Pleated PP Layer for Sediment Removal

The pleated polypropylene media provides large filtration surface area, effectively removing rust, silt, sand, and other suspended particles.

Activated Carbon Fiber (ACF) for Chlorine Reduction

The ACF layer offers fast adsorption and high surface area, targeting:

• Residual chlorine

• Unpleasant odors

• Organic compounds

• Taste improvement

PP Melt-Blown Inner Core for Strength

A rigid melt-blown polypropylene core supports the filter layers, ensuring uniform flow distribution and high structural stability.
