H2 Series Citric Acid Cleaning Cartridge

Usually ships in 24 hours.

The H2 Series water ionizers have continuous-cleaning inside the water cell, but if your water flow-rate slows it may mean it's time to do a citric acid wash. People with hard water may need to do some kind of citric acid cleaning every year or so. 

Using the Citric Acid Cleaning Cartridge makes it easier to clean the internal lines of the water ionizer than ever. All you need to do is install the special Citric Acid filter in the #2 spot of the ionizer and follow the directions, below.

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.
  2. Remove the second filter and insert the Citric Acid Cleaning Cartridge & lock in place.
  3. Run the water ionizer on Low-Alkaline mode at a slow trickle until it starts to come out of the tip of the spout.
  4. Let it sit for about an hour or so, overnight is fine if there is a lot of mineral scale, but multiple cleanings may be required.
  5. When finished, set the machine hoses back to normal. The under-sink ionizer hoses should have already stayed in the normal positions.
  6. Remove the empty Citric Acid Cleaning Cartridge and return the filter to its normal position, or replace both filters for a filter change.
  7. Rinse the machine for about a minute once you have the normal filter in properly. Use the neutral (filtered water) mode for this step.
