DI or KDF Refillable Empty Canister - Inserts Into a Big Blue 20 Inch x 4.5 Inch Housing
This 20 inch x 4.5 inch refillable canister will save you $$$$ compared with the cost of purchasing DI throw away filter elements. Just fill 6.5 Lbs. of DI resin into the canister and then insert the canister into a Big Blue 20 inch x 4.5 inch housing. When the resin is spent (depleted), the cap can be easily removed to dispose of the old resin and then refill with 6.5 Lbs. of new resin. The canister life is 20 fills or more before the the expansion sponge requires replacement.

This DI canister is compatible with RO systems and will polish the water to the highest quality of near zero (0) TDS.
