Compatible to Intelifil (IF-SM-WS020) 20"x2.5" 42,000 mg-L Water Softening Filter by IPW Industries
20"x2.5" 42,000 mg/L Water Softening Filter
This water softening cartridge uses dark cation bead resin to remove dissolved mineral hardness — the primary cause of scale buildup in pipes and appliances. Designed as a direct replacement for Intelifil IF-SM-WS020, it offers 42,000 mg/L hardness capacity in a 20" x 2.5" form factor with 10 micron nominal filtration. Best used with compensated hardness calculations that account for total mineral content of your source water.
What This Filter Does
Cation Resin Technology
Dark bead resin exchanges sodium ions for calcium and magnesium, reducing hardness minerals that cause scale formation
Standard 20" Dimensions
Fits most standard 20-inch filter housings with 2.5-inch diameter — no special equipment required for installation
42,000 mg/L Capacity
High grain capacity for extended service life — calculate replacement intervals using total hardness of your influent water
Broad Operating Range
Temperature range: 40°F to 100°F. Pressure range: 25 PSI to 100 PSI for residential and light commercial applications
10 Micron Nominal Filtration
Removes particulate matter while softening, protecting downstream equipment from sediment and mineral deposits
Drop-In Replacement
Compatible with Intelifil IF-SM-WS020 — same dimensions, same performance, reliable alternative source
Where This Filter Fits
This 20"x2.5" softening cartridge is designed for standard 20-inch filter housings from Watts, Pentair, Culligan, and other manufacturers using industry-standard dimensions. Compatible as a direct replacement for Intelifil model IF-SM-WS020. Ideal for point-of-use softening applications, pre-treatment for reverse osmosis systems, protection of tankless water heaters, coffee and espresso equipment, ice makers, and other appliances sensitive to hard water scale. Use compensated hardness calculations to determine service life based on your specific water chemistry.
Manufactured by IPW Industries to OEM specifications for filtration performance and dimensional accuracy.
