Compatible to Intelifil (IF-SM-KDF010B) 10"X4.5" Big Blue 2 Lb. KDF-55-GAC Chlorine-Heavy Metal Removal Filter by IPW Industries Inc
10"×4.5" Big Blue KDF-55/GAC Specialty Filter
This IPW-manufactured cartridge pairs 2 lbs of KDF-55 copper-zinc media with granular activated carbon in a 10×4.5 inch Big Blue format. The KDF handles inorganics, heavy metals, chlorine, and microbial suppression, while the coconut shell GAC focuses on organic compounds, taste, and odor. Built for whole house or dedicated drinking water filtration, this dual-media design outlasts standard carbon-only cartridges by 5× and works in water up to 100°F.
What KDF-55/GAC does differently
KDF-55 Heavy Metal Reduction
Copper-zinc granules remove lead, mercury, arsenic, and copper through redox and ion exchange, leaving GAC free to target organics
Coconut Shell GAC
High-surface-area activated carbon adsorbs chlorine, VOCs, THMs, and organic compounds that cause taste and odor issues
Microbial Suppression
KDF media inhibits bacteria and algae growth through electrochemical oxidation, preventing biofilm even in warm water applications
Scale & Lime Control
Reduces hardness precipitation and scale formation, protecting downstream fixtures and appliances in whole house configurations
10 Micron Nominal Rating
Captures sediment down to 10 microns while maintaining flow, suitable for pre-filtered municipal or well water sources
30,000 Gallon Lifespan
Lasts 5× longer than carbon block cartridges thanks to KDF's catalytic action and resistance to fouling from organics

Where this filter fits
This cartridge is a compatible replacement for the Intelifil IF-SM-KDF010B and fits any standard 10×4.5 inch Big Blue housing from Watts, Pentair, or other manufacturers using the nominal 4.5" diameter format. Designed for whole house filtration systems, point-of-entry applications, or dedicated drinking water installations where both inorganic and organic contaminant removal is required. Best used with pre-filtered water (5 micron or finer sediment pre-filter recommended) to maximize KDF and GAC lifespan. Not for use with untreated surface water or microbiologically unsafe sources.
IPW Industries manufactures this cartridge to OEM specifications with certified KDF-55 media and food-grade coconut shell activated carbon.
