Mixed Bed Deionization: Utilizes ion exchange material to effectively remove contaminants from water, ensuring ultra-pure output. High Efficiency: 1 lb of DI resin can process approximately 400 to 1,000 gallons of water, depending on the quality of the feed water. Extended Lifespan: The resin's longevity is directly tied to the feed water's PPM—lower PPM levels (such as 4 PPM from your RO system) significantly extend the life of the DI resin. Perfect for Refills: 6 oz of resin is ideal for refilling a 2" x 10" inline DI filter, while 1 lb will fill a 10" x 2.5" refillable housing.
