This 3-pack of Unger HydroPower Ultra replacement resin canisters keeps professional window cleaners producing 100% pure, spot-free water on the Large HydroPower Ultra DI tank. Each keylock canister is pre-filled with Unger high-capacity virgin mixed-bed resin, so when your TDS meter climbs you drop in a fresh canister and are back to producing pure water in seconds instead of scooping loose resin.

Frequently asked questions
Which Unger tank do these canisters fit?
They are sized for the HydroPower Ultra Large DI tank. The keylock opening ensures the canister seats correctly and does not leak once locked in.
How do I know when to change the resin?
Watch the system TDS meter. When the reading rises above roughly 000 to 010 ppm the resin is exhausted and the water is no longer pure, so it is time to swap in a fresh canister.
How is a canister faster than loose resin?
Instead of opening the tank and scooping bulk resin, you pull the spent keylock canister and drop in a new one, which Unger notes can speed the resin change by up to ten times.
Does pure water really leave glass spot-free?
Yes. Deionized water has no dissolved minerals, so it dries without the spots or film that tap water leaves, letting you rinse glass and walk away with no squeegee or towel drying.
