Harmsco - WaterBetter Series - 10" x 2.5" Pleated Sediment Filters
10" x 2.5" Pleated Sediment Filters
Polyester-Plus pleated cartridges engineered for maximum surface area and extended filter life across whole-house and RO applications
Industry-Leading Surface Area in a Standard Cartridge
4 Square Feet of Media
Pleated Polyester-Plus design delivers the largest surface area in a 10" x 2.5" cartridge, extending filter runs and reducing changeout frequency
3-5 GPM Flow Rate
Low initial pressure drop with high flow capability makes these cartridges ideal for both whole-house sediment filtration and RO pre-filtration
Cleanable & Reusable
Most micron ratings can be cleaned and reused multiple times, lowering operating costs and extending cartridge life in most applications
Thermally Bonded Caps
End caps are thermally bonded to the media—no adhesives—ensuring a reliable seal and preventing bypass in standard 10" housings
Technical Details
| Dimensions | 10" x 2.5" |
| Micron Ratings | 1, 5, 20, 50 micron |
| Filter Media | Polyester-Plus |
| Surface Area | 4 sq ft per 9.75" length |
| Flow Rate | 3-5 GPM per cartridge |
| Temperature | 140°F (200°F high temp version) |
| Certifications | NSF 61, FDA approved materials |
Fits Standard 10" Housings
Harmsco WaterBetter cartridges (WB-1W, WB-5W, WB-20W, WB-50W) are designed for all standard 10" x 2.5" filter housings. Use in whole-house sediment systems, RO pre-filtration stages, or any application requiring high-capacity pleated filtration. Compatible with Pentek, Culligan, GE, iSpring, and other housings accepting 10" x 2.5" cartridges.
Replacement Schedule
Municipal Water
Replace cartridge every 3-6 months depending on sediment load and household usage. Clean and reuse 1-2 times before final replacement in most micron ratings.
Well Water
Higher sediment levels in well water may require more frequent replacement. Monitor pressure drop and clean cartridges monthly to extend life between changeouts.
RO Pre-Filtration
Replace when pressure drop increases or when membrane performance declines. Typically 4-8 months in RO applications with moderate sediment levels.
Lower Operating Costs
Cleanable design and extended filter runs reduce total cost of ownership
Reduced Downtime
Fewer changeouts and longer service life keep systems running with minimal interruption
Engineered Media
Polyester-Plus filtration media designed specifically for superior sediment removal and durability
