Klarwod polypropylene string-wound filter cartridge for hot water, 10" length, 20 micron

The Klarwod polypropylene string-wound filter cartridge for hot water is a depth-style sediment filter designed to capture suspended solids, rust and particulate matter in hot water lines. With a 20 micron rating and a 10" length, this cartridge is intended for prefiltration in residential and light commercial applications, protecting downstream equipment such as water heaters, boilers and fine cartridges while improving water clarity and reducing sediment-related issues.

Advantages

This polypropylene string-wound cartridge provides consistent sediment capture through a graduated winding structure that traps particles throughout the depth of the media. The polypropylene construction offers chemical compatibility with common hot water environments and resists degradation at elevated temperatures. Its 10" length and 20 micron rating balance filtration efficiency and flow capacity, making it suitable for standard housings and routine replacement schedules.

Suitable for

• Prefiltration in residential hot water lines and point-of-entry systems
• Protecting water heaters and boilers from sediment and rust
• Pre-treatment ahead of finer cartridges or reverse osmosis units
• Light commercial hot water systems with moderate sediment loads

Key specifications

• Filter type: polypropylene string-wound depth cartridge
• Micron rating: 20 μm nominal
• Length: 10 inches (approx. 254 mm)
• Material: polypropylene fiber
• Operating temperature: suitable for hot water applications (follow system limits)
• End configuration: standard 10" cartridge fitting (check housing compatibility)

How to use

Install the cartridge into a compatible 10" filter housing following the housing manufacturer's instructions and ensure proper sealing of end caps to prevent bypass. Replace the cartridge when flow rate drops noticeably or when pressure differential across the filter reaches the threshold recommended by your system or housing manufacturer. Before installation, flush the housing and lines to remove loose debris; after installation, run water through the system to clear any trapped air and verify there are no leaks.

Usage recommendations

For reliable performance, use this cartridge as part of a staged filtration system: place it upstream of finer filters or sensitive equipment. Monitor pressure drop periodically and replace the element according to observed sediment load and manufacturer guidelines. Avoid exposure to chemicals outside typical hot water system use and confirm that operating temperatures remain within your housing and system specifications.
