Product Code IF-SM-KDF020B

$149.52
The IPW Industries compatible replacement for Intelifil IF-SM-KDF020B combines KDF-55 copper-zinc media with coconut shell granular activated carbon in a 20"x4.5" cartridge rated for 60,000 gallons. This dual-media design targets both inorganic contaminants like heavy metals and chlorine through KDF oxidation-reduction, while the GAC handles organics, taste, and odor for comprehensive whole house or commercial filtration.

COMPATIBILITY & APPLICATIONS

Where This Filter Works Best

This cartridge fits any standard 20-inch Big Blue housing with 4.5-inch inner diameter and serves as a direct replacement for Intelifil IF-SM-KDF020B. Ideal for whole house systems on municipal or well water where chlorine, heavy metals, and taste/odor issues coexist. The KDF-55 media handles the inorganic chemistry while the granular activated carbon adsorbs organics, giving you broader spectrum removal than carbon-only filters. Commonly used in commercial applications, point-of-entry residential systems, and well water treatment where multiple contaminant classes need simultaneous reduction. The 60,000-gallon capacity and 4 GPM flow rate make this suitable for homes with 2-4 occupants or light commercial use.

💧 KDF media works through redox reactions and lasts significantly longer than carbon alone—expect 5x the service life of standard carbon blocks, but monitor pressure drop as sediment will eventually load the 10-micron nominal rating.
