We get a lot of questions about storing ionized water. Which makes sense, it a bother to run your ionizer every time you want a drink of water, so many people opt to have a larger container that they fill and use to take glasses from.

Does storing ionized water ruin the benefits of the alkalinity?

storing ionized water in glass airtight jugBefore we talk about how long you can store the water and still get the benefits of ionization and hydrogen enrichment, let’s discuss what kind of container you’ll be storing it in.

Yes, alkaline ionized water is best stored in an airtight glass or stainless steel container.

It can be refrigerated or kept in a cool place. Avoid storing ionized water in aluminum containers.

  • The alkaline properties will be retained for 1-2 weeks, but they are strongest when fresh (within the first 3 days).
  • The antioxidant properties start to diminish after 18-24 hours.
  • For the new generation of hydrogen-rich water machines, the maximum benefit is obtained while you can still see the hydrogen bubbles in water, which last about 30 to 60 minutes.

For this reason, our bestselling unit is the non-electric Ionizer called the UltraStream, which has such an advanced design that it doesn’t require a cleaning cycle, therefore you can turn it on everytime you want a glass. And we also have the hydrogen water bottle from AOK, so you can create, fresh hydrogen water anywhere at any time!

So for the best benefits, drink it within a day or so. Here are some typical results for refrigerated ionized water, stored in a sealed glass container:
