H2 microbubble therapy on the Standard60: setup, distilled water, and what to expect

Updated September 2026

The H2 and Microbubbles System on the Ella Standard60 combines two therapies in one package: infusion microbubble therapy, which fills the bath with billions of tiny skin softening bubbles, and hydrogen therapy, which infuses the water with dissolved molecular hydrogen. On the Standard60, the system uses a 1 HP, 10A pump with a pressure vessel and agitator valve, and the hydrogen concentration reaches 1500 PPB, which is 1.5 ppm, by the time the tub fills, and can rise to about 2000 PPB during an extended 15 to 20 minute bath. One detail matters more than any other for great results: the blue tank must be filled with distilled water only.

First Time Setup on the Standard60

The hydrogen system ships with a container secured under the tub. Before your first use:

  1. Cut the shipping ties holding the container in place.
  2. Remove the container from under the tub.
  3. Connect the hose to the front of the tub.
  4. Fill the blue tank with distilled water. Distilled water is available at any grocery or drug store.

Tap water contains minerals that the system is not designed for, so topping up with anything other than distilled water can lead to weak output or a dirty tank over time. If your microbubbles ever seem weak, checking that the blue tank is filled with fresh distilled water is the best first step.

Running the System

Fill the tub until the water is above the hydrogen inlet jet and the microbubble port before you press the H2 button, since the pump must never run dry. Our guide to how much water to have before running the jets covers every system. One press starts the system and another press stops it. The water turns milky white as the microbubbles fill the tub, and the hydrogen concentration keeps climbing as the bath continues.

  3. 0:48 Benefits of Hydrogen Therapy Hydrogen neutralizes harmful free radicals, which causes cell damage and accelerates aging, and offers other potential health benefits.
  4. 1:19 Guaranteed Hydrogen Levels Each tub is individually tested for hydrogen production before shipping, with verifiable test results guaranteeing levels up to 2.2 parts per million.
  5. 1:40 Integrating Hydrogen Generators Any Ella walk-in tub can be outfitted with a built-in hydrogen generator, available separately or as a combo with other jetting packages.

As the video above explains, hydrogen water bathing infuses the bath with molecular hydrogen gas carried in nanobubbles, which helps the hydrogen remain in the water longer. With one touch of a button, billions of hydrogen nanobubbles are generated in the tub. Hydrogen molecules are tiny and highly permeable, and studies referenced in the video have explored potential benefits including muscle recovery, skin health, and relaxation. Every hydrogen tub is individually tested for hydrogen production before it ships, and it comes with verifiable test results showing the level of hydrogen produced in your specific tub. Ella's hydrogen content is not medical advice and is not intended to diagnose, cure or prevent any disease. Our warm-water bathing guidelines cover safe temperatures and soak times.

The second video shows the actual test: a 6 mL water sample is dosed with drops of a blue reagent that turns clear in the presence of dissolved hydrogen. With regular tap water the first drop stays blue, which indicates 0.1 parts per million or less, while in the demonstration tub outfitted with a hydrogen generator the twenty-second drop is the first to stay blue, and 22 drops corresponds to 2.2 parts per million. The published operating figures for the Standard60 are the 1500 PPB and 2000 PPB numbers above; the 2.2 ppm result belongs to the per-tub testing, and the test sheet that ships with your tub is the authoritative number for your unit. Our hydrogen therapy common questions article walks through PPB and PPM side by side.

What Microbubble Therapy Does

The microbubble system supersaturates the water with air and releases it as dense clouds of microbubbles smaller than 50 microns. These bubbles penetrate the first layer of skin and act as a natural exfoliant, leaving skin feeling softer, more hydrated, and healthier. Many customers with dry or sensitive skin tell us it is their favorite feature. You can run the hydro jets and the microbubbles at the same time, but to feel the full effect of microbubble therapy we recommend enjoying it on its own. For the standard microbubble option on other models, see infusion microbubble therapy.

On other Ella models, the optional microbubble package uses a 1 HP, 7.3A pump with a pressure vessel and agitator valve, and the same care guidance applies. For the rest of the Standard60's specifications, see the Standard and Standard60 profile.

Care and Troubleshooting

The monthly vinegar flush used on every jetted Ella tub keeps the microbubble lines fresh as well. If the pump buzzes without producing the milky cloud, first confirm the water level covers the port, then check the distilled water in the blue tank. Large bubbles instead of a fine cloud usually point to the pressure tank or agitator valve, and our article on a microbubble system that is not producing bubbles lists the checks in order.

Common Questions

Which tub offers hydrogen therapy?
The Standard60, 30 by 60 inches, is the model offered with the H2 and Microbubbles System. Ella's hydrogen page also describes custom installation in other Ella tubs as a special order where there is room under the deck; ask your Ella dealer or the team at (800) 480-6850 about any other model.
Does it really need distilled water?
Yes, the blue tank for the H2 and Microbubbles System on the Ella Standard60 must be filled with distilled water only. Tap water contains minerals that the system is not designed for, and using anything other than distilled water can lead to weak output or a dirty tank over time. If your microbubbles ever seem weak, checking that the blue tank is filled with fresh distilled water is the best first step.
Is 2.2 ppm the same as 2000 PPB?
Close, but not the same number. 1000 PPB equals 1 ppm, so 2000 PPB is 2.0 ppm and 2.2 ppm is 2200 PPB. The published operating figures are 1500 PPB at fill and about 2000 PPB during a long bath; 2.2 ppm is the up-to figure verified on the test sheet that ships with each tub.
Can I run the hydro jets and the H2 system at the same time?
Yes, you can run the hydro jets and the H2 and Microbubbles System at the same time. However, the full effect of the infusion microbubble therapy is strongest when enjoyed on its own. Many owners prefer to use the hydro jets first and then finish their bath with the H2 and microbubbles for the best experience.
How much water do I need before pressing the H2 button?
Before pressing the H2 button to start the H2 and Microbubbles System, the water in the tub must cover both the hydrogen inlet jet and the microbubble port. This is crucial because the 1 HP, 10A pump must never run dry. Running the pump without sufficient water can cause damage to the system.
Can hydrogen be added to my tub that already has the separate microbubble package?
The H2 and Microbubbles System is one combined unit rather than an add-on to the separate Infusion Microbubble package. Whether your particular tub can be fitted is a question for the team, who can check the space under your deck.
Can I get hydrogen therapy on the Ultimate or a LayDown tub?
The Standard60 is the model built with the H2 and Microbubbles System, and it is not offered on the Ultimate. Ella's hydrogen page describes special-order installation in other Ella tubs, and in selected standard bathtubs, only where there is adequate space under the deck, so ask your Ella dealer or the team at (800) 480-6850 before planning on it.
Does the hydrogen generator recirculate the bath water?
No, the hydrogen generator does not recirculate the bath water. It operates by drawing distilled water from its own blue tank and then injecting hydrogen into the bath through a single jet located below seat level. The hydro massage pump, if your tub is equipped with one, is the component responsible for recirculating the bath water.
How do I know my tub produces the stated hydrogen level?
Every Ella walk-in tub equipped with a hydrogen generator is individually tested for hydrogen production before it ships. Your tub will come with verifiable test results that show the specific level of hydrogen produced by your unit. For the Standard60, the published operating figures are 1500 PPB (1.5 ppm) by the time the tub fills, and up to about 2000 PPB during an extended 15 to 20 minute bath.
Do I need filtered house water for the hydrogen system?
The generator draws from its own distilled water tank, and the bath itself fills from your faucet as on any tub. Ella has not published a house water filtration requirement; if your water is very hard, ask the team before ordering.
