PP Cotton Filter

Efficient Sediment Removal for Water Filtration Systems

A PP cotton filter is a sediment filtration cartridge made from 100% polypropylene fiber, designed to remove sand, rust, dirt, and suspended particles from water.

It is widely used as the first-stage filter in residential, commercial, and industrial water filtration systems.


What Is a PP Cotton Filter?

A PP cotton filter is produced using melt-blown polypropylene technology, forming a dense yet porous structure that effectively traps sediment and particulate impurities.

The filter provides high dirt-holding capacity while maintaining stable water flow.

How a PP Cotton Filter Works

  1. Water flows from the outer layer to the inner core

  2. Larger particles are trapped on the surface

  3. Smaller particles are captured inside the fiber layers

  4. Clean water exits the filter

This gradient density structure ensures efficient filtration and long service life.


Key Benefits

✔ Effective removal of sediment and suspended solids
✔ Protects carbon filters, membranes, and valves
✔ High flow rate with low pressure drop
✔ Chemical and corrosion resistance
✔ Cost-effective and easy to replace
