9.75"x2.75" KDF-85/GAC Iron & Hydrogen Sulfide Filter Cartridge
Dual-Media Filtration Process
Particulate Removal
10 micron nominal filtration captures suspended solids, sediment, and particulate iron before reaching the primary media bed
Iron & Sulfide Reduction
Two pounds of KDF-85 media uses redox reactions to remove iron, hydrogen sulfide, lead, mercury, and arsenic while controlling scale and bacterial growth
Taste & Odor Polish
Coconut shell granular activated carbon adsorbs chlorine, VOCs, THMs, and organic compounds for final taste and odor improvement

Fits Standard 10-Inch Housings
This cartridge is compatible with Watts Intelifil IF-SM-KDF850102 and fits any standard 10-inch filter housing with 2.5-inch inner diameter. Suitable for point-of-entry whole house systems, under-sink RO pre-filtration, and specialty applications requiring iron and sulfur reduction. KDF media remains effective in hot water applications up to 100°F and provides bacteriostatic properties that inhibit microbial growth between service intervals. Replace when flow rate decreases significantly or when iron breakthrough becomes visible.
