All electric water ionizers produce both alkaline water and acidic water simultaneously. Most folks purchase a water ionizer for the health properties of the alkaline drinking water. But, did you know that there are a plethora of uses for the acidic water as well?

Acidic ionized water is for external use only, not for drinking. It's antimicrobial and astringent properties have found widespread use. In fact, water ionizers were being used in Japanese hospitals for the value of their ACID ionized water, long before the benefits of alkaline water were discovered.

What is Ionized Acid Water

Acid water can be characterized by the following:

  1. having a pH range between 2.0ph and 6.0ph
  2. having an ORP of +800 to +1200 (more info)
  3. having a hypochlorous acid component from 1-30 mg/l
  4. being micro-clustered
  5. being loaded with H+ (hydrogen ions), which acts as an oxidizer

Two Types Of Acid Water

There are two types of acid water; mild and strong.  ‘Mild’ acid water is used for the skin, hair and nails while ‘strong’ acid water is used for cleaning and sterilizing.

How To Get The MOST Acidic Water From Your Ionizer

Although most water ionizers allow you to choose "acid" water from the machine, which would then come out of the top stainless steel hose, there is a way to get the most acidic water from your ionizer (the lowest pH).

Set your machine to the highest "alkaline" setting that it will produce.  Then, slow the water flow rate down (either on the faucet or on an onboard flow-control valve, if you have one) to the slowest the water can come out while the unit remains powered on. On most ionizers with water flow sensors, if you slow the flow rate down too much, the ionizer will shut itself off - so make sure it is slow, but enough that the main power stays on.  Then, collect the acidic water from the acid hose coming from the bottom of the unit in a spray bottle or other glass bottle.

Doing it this way will give you the most powerful acid water that your ionizer can make. The results will vary from ionizer to ionizer, depending on the strength of the unit.
