Compatible to Intelifil (IF-SM-KDF85020) 20"x2.5" 20,000 Gal (2 lb) KDF-85-GAC Carbon Iron & Hydrogen Sulfide Removal Filter by IPW Industries
Compatible to Intelifil IF-SM-KDF85020 20"×2.5" KDF-85/GAC Iron & Hydrogen Sulfide Removal Filter
High-capacity specialty cartridge combining KDF-85 media with granular activated carbon for well water applications plagued by iron staining and sulfur odor. Fits standard 20-inch housings.
Dual-Media Chemistry for Well Water Challenges
KDF-85 Iron Removal
Dark granular KDF-85 media uses redox chemistry to convert dissolved ferrous iron into filterable particles, preventing rust staining on fixtures and laundry
Hydrogen Sulfide Control
The same redox process oxidizes hydrogen sulfide gas, eliminating rotten egg odor at the point of entry before it reaches faucets or appliances
GAC Polishing
Coconut shell granular activated carbon adsorbs chlorine, organic compounds, VOCs, and THMs while improving overall taste and odor characteristics
Bacteriostatic Effect
KDF media inhibits bacterial and algae growth through cellular disruption, maintaining filter performance even in warm water environments up to 100°F
Heavy Metal Reduction
Removes or reduces lead, mercury, arsenic, and copper through both ionic exchange and adsorption mechanisms across the dual media bed

Direct Replacement For
This IPW Industries cartridge is manufactured as a compatible replacement for the Intelifil IF-SM-KDF85020 filter. It fits any standard 20-inch whole house or well water filter housing with 2.5-inch cartridge diameter. Commonly used in Watts, Pentek, and other major brand housings designed for 20×2.5 specialty filters. Verify your existing housing accepts standard 20-inch cartridges before ordering.
Replacement Schedule for Well Water
Typical Household
For a family of four using well water, expect 12-18 months of service depending on iron and sulfide concentrations
High Iron Content
Wells with iron levels above 3 ppm may require more frequent replacement as KDF media becomes saturated faster
Performance Indicators
Replace when water pressure drops noticeably or when sulfur odor returns, indicating media exhaustion
Extend Filter Life
Use a 5-micron sediment pre-filter upstream to remove particulates and maximize the KDF-85/GAC cartridge lifespan
Whole House Protection
Treats water at point of entry for comprehensive iron and sulfur removal throughout the home
Standard Fit
Drops into existing 20-inch housings without modification or special tools required
Multi-Contaminant
Addresses iron, sulfide, chlorine, heavy metals, and organic compounds in a single cartridge
Hot Water Safe
KDF media remains effective up to 100°F, suitable for warm well water conditions
