IPW Industries Inc - Mixed Bed Deionization (DI) Cartridge - 20" x 4.5" & 25,000mg/L Cartridge - Compatible to Intelifil (IF-SM-DI020B) & Lowers TDS

Transform your tap water into ultra-pure deionized water with this 20"x4.5" Mixed Bed DI filter cartridge. Designed as a compatible replacement for Intelifil IF-SM-DI020B, this resin filter delivers exceptional results for aquarium enthusiasts, car wash operations, and anyone requiring di water. This deionized water filter uses advanced mixed bed resin technology, combining both cation and anion exchange materials to remove nearly all electrically charged ions from your water. Watch your TDS meter drop to near-zero ppm as it eliminates nitrates, phosphates, silica, and other dissolved solids. Whether you're maintaining a reef aquarium, running a deionized water system for car wash, or using it as part of your rodi water system for aquarium, this filter cartridge delivers consistent quality. Commonly used as a post-filter stage after reverse osmosis systems, this deionizer takes your water from 10-50 ppm down to 0-1 ppm TDS. However, it also works effectively as a standalone water deionizer. With a 25,000 mg/L capacity (1,450 GPG), calculate your filter life by dividing 25,000 by your feed water's TDS in ppm. Operating between 40°F-100°F with a maximum 3 GPM flow rate and 10 micron nominal rating, this 8 lb cartridge fits standard 20" filter housings. The refillable design offers significant cost savings—simply purchase bulk DI resin when exhausted and refill the cartridge yourself. This makes it an economical choice for regular aquarium water changes or ongoing deionized water needs in your ro di system for aquarium or water filtration system.

• NEAR-ZERO TDS OUTPUT: This mixed bed di resin filter cartridge eliminates nitrates, phosphates, silica, ammonia, and charged ions from your aquarium water. Use as a water deionizer for RODI system setups, pairing with your RO filters to produce ultra-pure deionized water. Watch your TDS drop to near zero ppm on your meter, creating ideal DI water for your fish tank, reef aquarium, and sensitive aquatic life in your reverse osmosis (RO) water system for aquariums.
• REFILLABLE FOR SAVINGS: Unlike disposable cartridges, this reusable filter cartridge lets you purchase replacement resin and refill it yourself when exhausted. This cost-effective design benefits aquarium enthusiasts who regularly use their RO system for aquarium water changes. Open the 8 lb cartridge, add fresh resin, and continue producing deionized water for your fish tank without constantly buying new replacement water filters, making it economical for ongoing aquarium filter needs.
• ULTRA-PURE WATER QUALITY: Designed to work as a final stage after your reverse osmosis system, this deionized water filter removes remaining dissolved solids that RO filters miss. Use it with your rodi filter setup or ro water system to achieve 0-1 ppm TDS deionized water. Also functions as a standalone water deionizer when needed, making it versatile for aquarium water, a deionized water system for car wash, inline water filter applications, or any situation requiring a deionized water system output.
• PREDICTABLE FILTER LIFE: With 25,000 mg/L capacity (1,450 GPG), simply divide 25,000 by your feed water's TDS to determine filter life in gallons. Features 20"x4.5" dimensions, 10 micron nominal rating, 3 GPM max flow rate, and operates between 40°F-100°F. When used after a RO system that reduces TDS to 10-50 ppm, this deionizer cartridge produces hundreds of gallons of pure DI water for your aquarium filter system, reverse osmosis water filter setup, or water filtration system needs.
• COMPLETE ION REMOVAL: Contains both cation and anion exchange resin mixed to remove nearly all electrically charged ions from water. This advanced resin filter technology delivers superior results for your rodi water system for aquarium, creating ultra-pure water with near-zero TDS. Compatible with standard 20" filter housings, it integrates seamlessly with your reverse osmosis water filter setup, RO filter system, or water filtration system to produce quality deionized water for fish tank maintenance.
