NUBE Copper Tank Disc

A simple upgrade for your NUBE

Keep your upper tank cleaner, naturally.

The NUBE Copper Tank Disc is designed to remain inside your NUBE's upper water tank, providing continuous copper contact with the stored water to help reduce biofilm, organic buildup and residue between regular maintenance cycles.

Small upgrade. Continuous protection.

Water can remain stored inside the upper tank for different periods depending on household consumption and NUBE usage. By keeping a copper disc inside the reservoir, you add a simple, passive layer of protection that works continuously — without electricity, chemicals or modifications to your NUBE.

Why add a Copper Tank Disc?

How to use it

1. Perform your regular weekly NUBE cleaning routine.
2. Wash your hands, open the top panel and then carefully open the upper tank, making sure not to damage the UV system.
3. Gently submerge the Copper Tank Disc all the way to the bottom of the upper tank, then close the tank immediately.
4. Every 3–6 months, remove the Copper Tank Disc and clean it using salt and lemon. Rinse thoroughly before placing it back inside the upper tank.
