Harmsco (WB-931-20) 29.25" x 2.75" WaterBetter Pleated Cartridge 20 Micron
Harmsco WB-931-20 29.25" x 2.75" Pleated Sediment Cartridge
Polyester-Plus pleated media gives you more surface area and longer service life than wound or spun cartridges
Pleated Design
More filtration surface area in the same footprint means longer runs between cleanings and better dirt-holding capacity than standard sediment cartridges.
Cleanable & Reusable
Rinse and reinstall in most applications. The Polyester-Plus media maintains structural integrity through multiple cleaning cycles, lowering your cost per gallon.
NSF 61 Certified
FDA-approved materials meet NSF 61 standards for drinking water contact. Safe for residential, commercial, and food and beverage applications.
Thermally Bonded Caps
End caps are bonded without adhesives for a positive seal. No bypass, no channeling, no risk of glue contamination in your water stream.
Harmsco WB-931-20 Filter Cartridge
Fits Harmsco proprietary filter housings
The WB-931-20 cartridge is designed for Harmsco housings that accept 29.25" x 2.75" diameter filters. This is a proprietary size. Confirm your housing dimensions before ordering. Common applications include pre-filtration for reverse osmosis systems, whole-house sediment removal, and food and beverage processing where a cleanable, high-capacity filter is required.
Service intervals depend on sediment load and water quality
Inspect & Clean
Check pressure drop. Rinse cartridge with clean water to remove accumulated sediment. Reinstall if media is intact and performance returns.
Replace if Needed
Replace the WB-931-20 cartridge when cleaning no longer restores flow, or if media shows tears, compression, or structural damage.
Commercial Grade
Engineered for high-flow commercial and industrial water treatment
Lower Operating Cost
Reusable design reduces replacement frequency and waste
Drop-In Replacement
Direct replacement for existing Harmsco WaterBetter cartridges
Versatile Applications
Works in RO pre-filtration, whole-house, and food service systems
