Watts-Compatible 10"×4.5" Mixed Bed DI Filter
This mixed bed deionization cartridge removes nearly all electrically charged contaminants—both cations and anions—from your water supply. Ideal as a post-filter for reverse osmosis systems or as a standalone filter for producing ultrapure water with TDS levels approaching zero ppm. Fits standard 10-inch Big Blue housings and delivers up to 2 GPM flow rate.
Mixed Bed Resin Technology
Ion Exchange Resin
Mixed bed resin captures both positively and negatively charged ions, reducing nitrates, phosphates, silica, ammonia, and other dissolved solids
Refillable Cartridge
Reusable housing design allows you to replace only the DI resin once exhausted, reducing long-term operating costs
TDS Near Zero
Produces ultrapure water measurable with a TDS meter, ideal for aquariums, hydroponics, laboratories, and precision applications
10 Micron Nominal
Provides sediment filtration while the resin handles dissolved contaminants for comprehensive water polishing
2 GPM Flow Rate
Suitable for whole-house applications or dedicated point-of-use systems requiring consistent ultrapure water delivery
Standard Big Blue Size
10-inch by 4.5-inch dimensions fit most 10-inch Big Blue filter housings without modification

Filter Life Calculation: Divide 12,000 by your feed water TDS in ppm. Example: 50 ppm feed water = 240 gallons capacity (12,000 ÷ 50).
System Compatibility
This cartridge is designed as a compatible replacement for the Intelifil IF-SM-DI010B mixed bed deionization filter. Fits standard 10-inch Big Blue housings from Watts, Pentek, and other manufacturers using the 10" × 4.5" cartridge size. Commonly used as a post-filter in reverse osmosis systems, whole-house ultrapure water systems, aquarium filtration, hydroponic applications, laboratory water purification, and any application requiring near-zero TDS water. Works in both point-of-use and whole-house configurations.
Manufactured by IPW Industries to meet or exceed OEM specifications for Watts-compatible filtration systems.
