Nexus & Smart Citric Acid Cleaning Cartridge

The Nexus Citric Acid Cleaning Cartridge is an easy-to-use solution to hard water scaling within any Nexus water ionizer.

Citric Acid Cleaning Cartridge Directions:

1. Gently tilt the Top Spout up above the height of the ionizer & clip the acidic hose at an equal height. [Both hoses are up higher than the machine, because you don't want the citric acid water to drain until this process is done.]
2. Remove the second filter and insert the correct Citric Acid Cleaning Cartridge for your machine.
3. Run the water ionizer on Level 1 or 2 Alkaline mode for a few seconds, until it starts to come out of the tip of the spout.
4. Let it sit for a few hours, or overnight.
5. When the time is up, set the machine hoses back down in their normal spots. The under-sink ionizer hoses should have already stayed in the normal positions.
6. Remove the empty Cartridge and return the regular filter #2, or replace filters if it's time for a filter change.
7. Rinse the machine for about a minute once you have the normal filter inserted properly. Use the neutral (filtered water) mode for this step.

Note: The Jupiter and Nexus Citric Acid Filters are the same. With Jupiter ionizers, remove the rubber gasket at the bottom of the filter and it will fit.
