COMPATIBILITY
What Works with This Filter
The Harmsco 801-5-20 fits any standard 20-inch filter housing with a 2.5-inch inner diameter. It is designed for use in Harmsco's own housing systems as well as compatible whole-house and well water housings from other manufacturers. This 5 micron pleated cartridge is ideal for sediment removal in residential, light commercial, and agricultural water treatment applications where higher flow rates and longer service intervals are required.
🔧 Pro tip: Pleated filters like the Harmsco 801-5-20 can often be rinsed and reused 2-3 times before replacement, extending filter life in high-sediment well water applications. Use a garden hose to flush from the inside out, then inspect the pleats for damage before reinstalling.
