Glass Dispenser
Replacement cartridges sold on their own don’t include the housing and aren’t covered by this patent.
Keep the housing.
Swap the cartridge.
The housing is the part you keep. Each refill replaces only the CoreXchange™ cartridge inside, so there’s less plastic to throw away.
Lift out the filter. Open the housing.
Swap the cartridge. Drop in a fresh CoreXchange™ cartridge.
Close it up. Same housing, fresh filter, less waste.
