DI Resin, 1.25 lbs


DI Resin is used as a final stage in an RO/DI system to fully remove all ions and provide zero TDS water.  

Our DI Resin is a premium grade, gel type, high capacity, mixed ion exchange resin prepared with a 1:1 chemically equivalent ratio of cation to anion resin. 

This is our non color changing resin.  If you monitor your water output with a TDS meter, there is no need for the extra cost of the color changing resin.

Our DI resin is vacuum sealed in single-use mylar bags to prevent any air intrusion.  Once it is opened and exposed to air, it begins depleting.  To maximize efficiency and shelf life, we only supply single use packets (but quantity discounts are available)!  Each packet is enough to fill one standard 10" refillable cartridge.
