Water filter cartridge Klarwod PP10-20 — string-wound polypropylene, 10–20 µm

Klarwod PP10-20 is a string-wound polypropylene water filter cartridge with a 10–20 µm retention range designed for mechanical prefiltration. It captures sediment, rust, sand and other particulate matter from potable and process water to protect downstream filters, membranes and equipment. The cartridge fits standard household and light commercial filter housings and is intended as a replaceable sediment stage for systems that require reliable coarse filtration.

Advantages

The polypropylene string-wound construction provides consistent depth filtration and high dirt-holding capacity while maintaining low pressure drop. The graded density design captures larger particles on the outside and finer particles toward the core, improving service life and reducing clogging of subsequent stages. The material is chemically inert for typical potable water conditions and resists biological growth when used in accordance with maintenance schedules. The cartridge is simple to install and replace in common filter housings.

Suitable for

• Pre-filtration in household drinking water systems
• Protecting activated carbon and membrane stages in multi-stage filters
• Industrial or process water coarse filtration where 10–20 µm retention is acceptable
• Reducing sediment, rust, sand and visible particulates from municipal or well water

Key specifications

• Filter type: string-wound polypropylene sediment cartridge
• Retention rating: nominal 10–20 micrometers
• Filtration mechanism: depth filtration with graded density
• Compatibility: standard household and light commercial filter housings designed for replaceable cartridges
• Typical use: mechanical prefiltration to protect downstream stages

How to use

Install the cartridge in the filter housing following the housing manufacturer's instructions, ensuring proper orientation and sealing. Flush the housing after installation until the water runs clear. Replace the cartridge when flow rate is significantly reduced or when visible contamination accumulates on the filter surface. Dispose of used cartridges according to local waste regulations. For reliable performance, pair this cartridge with finer final-stage filters such as activated carbon or membrane elements where needed.

Usage recommendations

Monitor pressure differential across the cartridge and establish a replacement interval based on incoming water quality and flow requirements. Use this cartridge as a sediment/pre-filtration stage; do not rely on it for microbiological disinfection or removal of dissolved contaminants. Store spare cartridges in a dry, clean environment away from direct sunlight.
