Replacement string-wound polypropylene water filter cartridge Klarwod PP10-5 — 5 µm

Klarwod replacement string-wound polypropylene cartridge PP10-5 provides nominal 5 µm mechanical filtration for pre-treatment of residential and light commercial water systems. The cartridge is designed for installation in standard 10" housings and uses multi-layered polypropylene winding to trap sediment, rust, sand and other particulate matter. It is intended for use with well water, municipal supplies or household lines where reduction of suspended solids is required before finer filtration or point-of-use treatments.

Advantages

The string-wound construction ensures progressive depth filtration, capturing larger particles at the outer layers and finer particles toward the core, which extends service life compared with simple surface filters. Made of polypropylene, the cartridge resists chemical degradation from common water treatment additives and does not shed fibers into the water stream. Its standard 10" size and nominal 5 µm rating make it compatible with most common housings and suitable as an effective pre-filter ahead of carbon blocks, reverse osmosis membranes or UV systems.

Suitable for

• Pre-filtration in residential water filter housings (standard 10").
• Reduction of sediment, rust and sand in well and municipal water supplies.
• Protection of downstream fine filters, membranes and appliances.
• Light commercial water systems requiring particulate removal.

Key specifications

• Filter type: string-wound polypropylene depth cartridge.
• Nominal filtration rating: 5 µm.
• Size: standard 10-inch cartridge compatible with 10" housings.
• Material: polypropylene (synthetic fibers, layered winding).
• Function: mechanical sediment and particulate removal.

How to use

Install the Klarwod PP10-5 cartridge into a compatible 10" filter housing following the housing manufacturer's instructions. Ensure the water supply is shut off and pressure relieved before opening the housing. Place the cartridge with correct orientation if the housing specifies inlet and outlet sides, then reassemble the housing and restore water flow. Monitor pressure drop across the filter and replace the cartridge when flow decreases noticeably or at regular intervals based on water quality and usage.

Usage recommendations

For optimal performance, use this 5 µm cartridge as a pre-filter ahead of activated carbon, membrane or UV systems. Replace the cartridge sooner in water with heavy sediment or after well maintenance. Periodically inspect the housing for accumulated debris and follow local water treatment guidelines to determine replacement frequency.
