Compatible to Intelifil (IF-SM-WS020B) 20"x4.5" 84,000 mg-L Water Softening Filter by IPW industries
20" x 4.5" 84,000 Grain Water Softening Filter
This softening resin cartridge uses dark cation bead technology to remove dissolved hardness minerals that cause scale in pipes, appliances, and fixtures. Built to the IF-SM-WS020B specification, it offers 84,000 mg/L capacity with a 10 micron nominal rating for dual-action filtration and softening in one cartridge.
What This Cartridge Does
Cation Resin Technology
Dark bead resin exchanges hardness ions for sodium, removing calcium and magnesium from water before they form scale deposits
Scale Prevention
Protects water heaters, dishwashers, washing machines, and plumbing from mineral buildup and efficiency loss
Standard Big Blue Size
20" x 4.5" dimensions fit most standard Big Blue housings without modification or special fittings
10 Micron Filtration
Nominal 10 micron rating captures sediment and particulates while softening, providing dual-action water treatment
Wide Operating Range
Performs reliably in temperatures from 40°F to 100°F and pressures from 25 to 100 PSI for versatile installations
84,000 mg/L Capacity
High grain capacity handles significant hardness loads; use compensated hardness calculations for accurate service life estimates
Where This Filter Works
Designed as a direct replacement for Intelifil IF-SM-WS020B cartridges. Fits standard 20-inch Big Blue filter housings from Watts, Pentair, Culligan, and other manufacturers using 4.5" diameter cartridges. Ideal for point-of-entry water softening in homes with moderate to high hardness, well water systems, and applications where traditional salt-based softeners are impractical. Use in residential whole-house systems, commercial appliances, or as pre-treatment for reverse osmosis and other sensitive equipment.
Manufactured by IPW Industries to OEM specifications for reliable performance and consistent hardness reduction.
