Your Nexis owner's guide

• If the light is red or flashing red, charge it.
• If there's no light at all, try a different 5V / 1A wall plug and check the cable.
• Some models need the button held for 3 seconds to wake up.

• Red: needs charging. Green: fully charged. Flashing red: empty battery or the wrong charger.
• Use a standard 5V / 1A plug. Fast chargers and computer USB ports often don't work.
• Check that the cable is pushed all the way in, and that the port is dry, clean and undamaged.

A full charge gives up to 8 five-minute cycles, and fewer 10-minute cycles. On a 3-bottle plan, expect to charge every day or two. If it runs down much faster than that, contact us and we'll check it under your warranty.

• Remove the membrane plug if it's still on.
• The membrane may be dry. Fill with warm water, below 60°C / 140°F, and let it sit for 1 hour. Then run a few cycles with warm water. Output can keep improving over about 10 days of use.
• Check your water type, and do the vinegar clean.

• Stop using it and contact us before you use it again.
• Keep the water below the hole in the cap. Too much water can stop the pressure from venting.
• Open the cap after each 10-minute cycle, or after every two 5-minute cycles.
• Check the silicone seal for damage, twisting or a missing ring.

That's normal. The base vents oxygen during a cycle, and a little water can come out there. Water from the cap, or between the bottle and the base, is a leak.

That's normal. It's the pressure built up during the cycle. Open the cap slowly.

Rinse after every bottle and disinfect twice a week. Don't leave it unused in a warm place. If the smell stays, contact us.

Many people don't feel a clear change, especially early on. Check the basics: approved water, a 10-minute cycle and drinking it right away. Give it a few weeks of steady use, and call us if you have questions.

Stop using it and talk to your doctor. Don't assume a new symptom is just your body adjusting.

Distilled or reverse osmosis water is best. Purified bottled water and filtered water (pitcher, fridge or under-sink filter) are fine. Avoid unfiltered tap water, spring or mineral water, and never use alkaline water in the device.

A cycle is 5 or 10 minutes. Independent labs measured about 5.4 ppm after 5 minutes, and 7.7 to 8.7 ppm after 10 minutes. For a stronger result, run 10 minutes, open the cap to release pressure, then run 5 more.

That hole is the pressure release valve. If water covers it, pressure can't vent properly, which can cause leaks. Fill to the MAX line or lower, about 280 mL / 9.5 oz.

Yes. Always open the cap after each 10-minute cycle to release the pressure before you drink or run another cycle.

Our plans start at 2 bottles a day (560 mL / 19 oz), close to the roughly 500 mL a day often suggested by hydrogen researcher Dr. Shigeo Ohta. Some people use 3 bottles on busy or active days. It's a daily supplement, not your only source of water.

Research hasn't found a harmful amount of hydrogen itself. One study used over 5.5 millimoles a day, and one Nexis bottle holds about 1.2 millimoles. The real limit is the water: if your doctor limits your fluids, count these bottles.

Rinse with warm water after each use. Twice a week, disinfect the membrane with white vinegar or Ocemida cleaning solution for 30 minutes, device off. Wash only the bottle and cap with soap. Never put the base in water or use soap on the membrane.

No. Hand wash the bottle and cap only, and keep the base dry.

A standard 5V / 1A USB wall plug, like an older phone charger. The wall plug isn't included. Avoid fast chargers, computer USB ports and public charging stations, which can cause charging faults.

The membrane needs to stay damp, so each unit ships moist and sealed with the membrane plug. Some water can move around during shipping. Just unscrew the plug before first use.

When the device will sit unused for a while, or when you travel. It keeps the membrane damp and protects it from dust and mold.

There can be if it sits unused in a warm place for a long time. Rinse after each use and disinfect twice a week to prevent it.

No. Soap and harsh cleaners damage it. Use only plain water or white vinegar on the membrane, and a cotton swab on the threads. Never brush or scrape the electrodes.

No. Hydrogen water has hydrogen gas dissolved in it. Alkaline water has minerals that raise its pH. They are different things.

Yes, a little. Don't put the device in the fridge. Use cold water in the bottle, or pour the finished water over ice in a glass.

No. It tastes like plain water.

Not into the bottle. Only plain water goes in. If you like, pour the finished water into a glass, add it there and drink right away.

Yes. Drink your hydrogen water on its own first, then your coffee or tea. Some people like making cold brew coffee with the finished water.

None. It's water with hydrogen gas dissolved in it.

These plans are written for adults. Ask your child's doctor first.

It's water with dissolved hydrogen, but check with your vet first, especially if your pet has a health condition.

Some people like to. Research on this is limited, so think of it as a personal preference. Use it right after a cycle.

Heat drives the hydrogen out, so there's no benefit. Drink it fresh.

Yes. Make a fresh bottle for each person and rinse it in between.

Hydrogen escapes once the cap is open, so the bottle holds one serving to finish while it's fresh. A smaller amount of water also reaches a higher hydrogen level.

Bottled water labeled "distilled" or "purified by reverse osmosis". Avoid water labeled "alkaline", "mineral" or "spring". Pack the membrane plug.

It uses a high-pressure design with a reinforced chamber and a thick Tritan bottle. That lets it go well beyond the roughly 1,600 ppb that water holds at normal pressure.

As long as you enjoy it. There's no need to take breaks.
