The Very Best Way to Store Ionized Water

Posted by Alkaline Water Plus on

The best way to fill the bottles of ionized water is to over-fill them and carefully cap them in such a way as to try to get  no air bubble.

When you do this it will maintain the pH and ORP much better.

ORP: Oxidation Reduction Potential [the antioxidant value of the ionized water] tends to degrade with exposure to air of ionized water. ORP is one of the main qualities of ionized water that makes it so healthy. A low negative ORP is what we are looking for. This will give you lots of antioxidants. The lower the better.

Storing for 1-2 hours

Here I have tested the ionized water before filling the bottles and then fill them with as little air bubble as possible. Then waited for a couple hours and tested again.




Ionized Water 10.4 -750


Mason Jar 10.2 -750
Glass Bottle 10.5 -715
White Plastic Bottle 10.6 -605
Fiji Bottle 10.6 -545
Evian Bottle 10.7 -590
Dasani Bottle 10.8 -480
Aquafina Bottle 10.8 -455
Little Plastic Jug 10.8 -440

As you can see, the mason jar was almost exactly the same ORP and pH as the original ionized water before it was stored! This is THE best way to store ionized water. One key thing to do is to ensure that there is no air bubble in the container.

Storing for One Day

Here are some results from further [off-video] testing I did with storing ionized water. I let some containers sit for one day with ionized water. These are some, but not all, of the containers shown in the video above.




All 10.5 -750


White Plastic Bottle 10.6 -365
Little Plastic Jug 10.8 -200
Dasani Bottle 10.7 -309
Glass Bottle 10.6 -425
Mason Jar 10.4 -690

As you can see, the mason jar wins again, by a long shot. The glass bottle is a close second.

So if you have to store your ionized water while at work or for any other reason, consider using a mason jar…and don’t forget to overfill it [try to get no air-bubble]. This is a good way to keep the ionized water as “fresh” as possible.

Storing for Several Days

I did some further testing of storing water using mason jars. You can see in the following videos that in the even after several days, the Mason jars kept the ionized water’s pH and ORP in desirable ranges. The pH and ORP had dropped, but would be still good and healthy water to drink. Mason jars are made for preserving things, so it does make sense that they are so great for storing ionized water!

Ionized Water Testing: Clean your ORP Meter

ORP [oxidation reduction potential] meters are scientific instruments which measure the antioxidant qualities of ionized water. I use an ORP meter when I'm doing water ionizer comparisons, as one of many tests. Read more about the  benefits of antioxidants in ionized water. ORP meters are an essential for me, because I am constantly testing and comparing new and [...]

Ionized Water, Digestion & a Good, Healthy Colon

Hydrogen water benefits digestion in many waysDepending on the type of hydrogen machine you use, the water's pH can vary.  If your hydrogen water is coming from a water ionizer it will be alkaline, which doesn't particularly help the digestion of meat and dairy. So, when drinking ionized water with a meal I suggest to add [...]
