What’s in the box
- 3, 6 or 9 Living Aqua replacement filters, depending on the pack you choose
Fits the Living Aqua Hydrogen-Rich Alkaline Water Pitcher. Each pitcher already comes with 1 filter.
How to replace the filter
- Remove the old filter and rinse the pitcher with warm water, without harsh detergents.
- Soak the new filter in clean water for 3–5 minutes, pour that water out, then set the filter in place.
- Fill the pitcher and pour out the first batch of water after the change — it flushes the new filter, so the first batches may look slightly cloudy. After that, use the pitcher as usual.

Readings depend on the quality, mineral content and temperature of your source water.
Living Aqua replacement filters turn ordinary drinking water into hydrogen water, rich in dissolved molecular hydrogen (H₂). Thanks to the filter’s mineral blend, the water takes on a negative oxidation-reduction potential (ORP) and a gently alkaline pH. One filter lasts 6–8 weeks — up to 300–350 L (79–92 gal) of water. Get a pack: it lasts longer, and you save.
What happens inside the filter
The filter is the heart of the ionizing pitcher: one replaceable filter = 4 stages. It doesn’t just filter the water — it makes it hydrogen-rich: it adds molecular hydrogen (H₂), gives the water a negative ORP and a gently alkaline pH.
Mechanical filtration
The first layer traps visible particles — sand, rust and sediment from the pipes — so the water reaches the next layers already clean.
Activated carbon
A layer of coconut activated carbon reduces chlorine, odors and off-tastes. The water comes out clear, without that “tap water” taste.
Mineralization
Puts natural minerals back and makes the water soft, with a pleasant, gently alkaline taste — close to water from a mountain spring.
Hydrogen (H₂)
Adds molecular hydrogen and lowers the oxidation-reduction potential (ORP). That’s what turns it into hydrogen-rich, antioxidant-active “living water”.
In short: the filter adds molecular hydrogen (H₂), a negative ORP and a gently alkaline pH — each filter lasts 6–8 weeks, or 300–350 L (79–92 gal).
Replaceable: when to change it, and why a pack pays off
The filter is the part of the pitcher you replace. One filter lasts 6–8 weeks, or up to 300–350 L (79–92 gal) of water; after that, change it so your water stays clean and hydrogen-rich.
Signs it’s time for a new filter:
- The water runs through more slowly than before.
- The taste has changed, or there’s an off taste.
- It has reached its service life — 6–8 weeks or 300–350 L (79–92 gal).

Answers to common questions
Can’t find your answer? Leave your number below and we’ll call you back.
How often should I change the filter?
One filter lasts 6–8 weeks, or up to 300–350 L (79–92 gal) of water. Go by whichever comes first: with heavy use, a filter runs out before the calendar says so.
Does it fit my Living Aqua pitcher?
Yes — it’s the original replacement filter for the Living Aqua Hydrogen-Rich Alkaline Water Pitcher. Take out the old filter and put in the new one; no tools needed. Don’t have the pitcher yet? See the pitcher.
Is the filter material safe?
Yes. The housing is food-grade plastic, and every layer inside — the mechanical filter, coconut activated carbon, the mineral layer and the hydrogen module — is designed for direct contact with drinking water.
How much water does one filter treat?
One filter filters and adds hydrogen to up to 300–350 L (79–92 gal) of water. A pack of 3, 6 or 9 filters covers roughly 1,000, 2,000 or 3,000 L (264, 528 or 792 gal).
How do I start a new filter?
Soak the new filter in clean water for 3–5 minutes and pour that water out. Set the filter in the pitcher, fill it, and pour out the first batch of filtered water — it flushes the new filter, so the first batches may look slightly cloudy; that’s normal. After that, use the pitcher as usual.
What is hydrogen water?
Put simply, hydrogen water is ordinary drinking water infused with molecular hydrogen (H₂) — much the same way sparkling water is infused with carbon dioxide (CO₂).
The science is young, but it is growing fast. In 2007, a team led by Prof. Shigeo Ohta reported in Nature Medicine that molecular hydrogen acts as a selective antioxidant. That paper opened the field to serious study.
Since then, more than 3,000 studies on molecular hydrogen have been published by researchers in Japan, Korea, China, the United States, Germany, Mexico, Serbia, Slovakia and Ukraine.
Hydrogen-rich water also has a negative ORP — a measurable sign of its reducing (antioxidant) potential that you can check yourself with an ORP meter.
Why hydrogen water?
The antioxidant capacity of just 34 oz (1 liter) of hydrogen water compares to hundreds of servings of fresh produce — an antioxidant boost every day.
How much produce would it take?
To match that antioxidant capacity, you’d have to eat:
🍌
756
bananas
🍎
516
apples
🥕
38
carrots
3.7
pumpkins
pH 9.0
H₂ 1,000 ppb
ORP −250 mV
Example reading · zero calories
Hydrogen water is water saturated with molecular hydrogen H₂, with a mildly alkaline pH and a negative oxidation-reduction potential.

I found out about the ionizing filter on social media. After reading the reviews, I decided to order a set and try it. I’m happy with the result — the water quality really improved, and the taste became softer and more pleasant. The pitcher itself is easy to use and made of sturdy materials. I recommend it.
