What is the Shelco 20″ x 2-1/2″ String-Wound Sediment Cartridge Filter for High Temps Used For?
Use this cartridge when you need sediment reduction to protect equipment and improve water clarity, including:
- Prefiltration before carbon filtration, RO, DI, UV, and other specialty stages
- Sediment reduction in residential, commercial, and light industrial lines
- Applications where predictable depth filtration and dirt holding capacity matter
How to Choose the Right Micron Rating
- 50 micron: coarse filtration for heavier visible sediment and longer run time
- 20 micron: general sediment reduction for common dirt, rust, and particulate
- 5 micron: finer filtration for smaller particles and better polishing protection

Installation Guidance for the 20″ x 2-1/2″ String-Wound Sediment Cartridge Filter
Install difficulty: easy
Basic Replacement Steps
- Shut off water to the housing and relieve pressure.
- Place a towel or pan under the housing.
- Remove the sump, remove the used cartridge, and clean the housing interior.
- Inspect the housing O-ring and replace it if worn.
- Insert the new cartridge, reassemble, and hand-tighten the sump.
- Turn the water on slowly, check for leaks, and flush until the water runs clear.
Maintenance Schedule
- Inspect and replace based on pressure drop, visible loading, or scheduled maintenance
- Keep spare cartridges on hand if your system is high-use or sediment-heavy
Questions on String-Wound Sediment Cartridge Filters
Q: What does a string-wound sediment cartridge remove?
A: It reduces physical particulates such as dirt, rust, and sediment that can cloud water and load downstream equipment.
Q: Will this fit my housing?
A: It fits standard 20-inch x 2.5 inch housings designed for industry-standard 20-inch cartridges.
Q: What is the difference between 5, 20, and 50 microns?
A: 50 micron is coarser and typically lasts longer with heavy sediment, 20 micron is a common general sediment option, and 5 micron provides finer polishing filtration.
Q: Is this cartridge washable?
A: String-wound cartridges are typically replaced, not washed, because sediment is trapped throughout the depth of the media.
Q: Is this rated for high-temperature use?
A: High temperature versions with stainless steel center tubes are rated up to 180°F (82.2°C). Confirm your configuration matches your temperature requirements.
Q: Does this cartridge improve chlorine taste and odor?
A: No. This is a sediment cartridge. Carbon filtration is typically used for chlorine taste and odor.
Q: How do I know when it is time to replace it?
A: Replace when the flow drops, the pressure drop increases, the cartridge is visibly loaded, or you reach your planned maintenance interval.
Choose your micron rating, install a Shelco MicroSentry 20-inch string-wound cartridge, and keep sediment under control to protect downstream filtration and equipment.
