Make Your Own Alkaline Ionized Water Right at Home


Washijng Your Fruits and VegetablesThere are several ways to make alkaline ionized water. You could use a little baking soda or just add lemon juice to water and alkalize it that way. Of course, lemon juice is acidic — but when you actually drink it you are “alkalizing” your body. You see, when people talk about aid and alkaline balance with water, they are actually using short-hand. What they really mean is “alkaline-forming” and “acid-forming” — terms to how the body responds to what you are eating or drinking. Many fruits are acidic, like lemons, and “alkaline-forming” in your body. But remember, this home-brew system doesn’t filter your water at all…it just alkalizes it.

A water ionizer is a home appliance that can raise the pH of drinking water by using electrolysis to separate the incoming water stream into acidic and alkaline components. There are several scientific studies which show that drinking alkaline ionized water has many health benefits. See my other posts on alkaline water for some references.

For pure, clean healthy water you need to use a filter system before using this home brew ionizer, like the Berkey water filter system. Berkey makes some the most powerful filtering systems available. The filters provide reliable high quality quality water, removing viruses, pathogenis, cparasites, and dangerous chemicals.

Commercial alkaline ionized water systems can cost from under $1,000 to over $4,000, yet it’s quite easy to build your own basic system for nearly the same end results and for much less money.  However, it will require a bit of time and effort on your part.  Building your own basic water ionizer will let enjoy many of the benefits of the more expensive models. And they make fun, educational projects for a science fair or school project. Difficulty: Moderately Challenging.

Things You’ll Need:
  • Two 1-gallon plastic storage containers (BPA-Free plastic)
  • One 2-inch PVC pipe
  • Electrical wire (NSF Certified Medical Grade Titanium)*
  • Piece of chamois cloth or other organic fiber cloth slightly larger than PVC pipe for a membrane
  • 12V or 24V power adapter
  • Two crocodile clips
  • Two 0.5-inch by 0.75-inch pieces of Platinum Coated Medical Grade Titanium to use as electrodes (NSF Certified)*

Step 1: Set up the 2 1-gallon plastic containers next to each other and cut a 2-inch hole on the side of each one so that they line up and face each other.
Step 2: Insert the chamois cloth or membrane into the PVC pipe so that it fills the entire diameter of the pipe, like a wad or ball, and insert the pipe into the 2 holes you cut out of the plastic containers.
Step 3: Attach the titanium electrodes to some electrical wire.
Step 4: Attach the alligator clips to the 12V or 24V power system and to the wire that is running to the titanium electrodes.
Step 5
: Place a titanium electrode in each 1-gallon plastic container, and make sure the contact between the alligator clips and the wire running to the electrodes remain out of the water.
Step 6: Fill the containers with water from your faucet and turn on the power adapter. This initiates the ionizing process.
Step 7: Wait at least 2 hours and watch as the water separates into the 2 containers. The water in one container will turn brown and murky while the water in the other container will be clear and clean. Once the ionizing process is complete (up to 12 hours), the brown water is the acidic water and the clear water is the alkaline water.


  • A home-made ionizer system takes much longer to make alkaline ionized water than commercial systems since you use much smaller electrodes and less power. Commercial alkaline ionized water devices make the water instantly on demand.
  • The chamois cloth inside the PCV pipe may get moldy or need replacement. Remove the membrane, squeeze it out, and let it dry between use, or just soak it in acid water. If the ionizer is used daily mold probably won’t grow. Remember to use organic unbleached natural fibers.

Remember, this is moderately challenging project and exposes you to electrical current and water. Be careful and know exactly what you’re doing before you build.

* Please use only medical grade platinum plates titanium electrodes. Other materials, like stainless steel, will break down and leach into the water making it impure. ASTM-F67 Titanium is recommended.

I studied nutrition at U.C. Berkeley and was a nutrition writer for Shaklee Corp. in the 1980s. I became a raw foodist in 1995 at the Optimum Health Institute of San Diego where I taught raw food for several years. Later, I taught at New Life Expos, Wild Oats stores and many other venues. I created this website in 1996. My greatest joy is learning about raw food, nutrition, health and more then sharing it with you. Thanks for making the #1 website for Raw Food!
