Not Sure if Hydrogen Water Bottles Are for You? Here’s What a Doctor Wants You to Know About Them — and 6 We Recommend

Sirios recommends the Level Up Way Hydrogen Generator Water Bottle. It’s easy to use, due to its simple design and the fact that there are no complicated setup parts or cartridges to worry about. After filling the bottle with water, all you have to do is press a button, and the bottle starts making hydrogen. It runs for around five minutes and stops when the hydrogen water is ready to drink. An LED display on the bottle shows its status, and a beep will let you know when it’s done. It’s easily rechargeable with a regular USB cable and has up to 20 uses between charges. The bottle’s advanced design filters out chlorine and ozone without additional filters or outside processes. It’s recommended that you use filtered water or spring water, since the bottle doesn’t filter water itself, but tap water is okay to use (though not preferred). The bottle is made from durable, high borosilicate glass, so it won’t leech plastic into your water.

This bottle also boasts a high hydrogen output. If you leave it on for five minutes, it can deliver up to 3,000 parts per billion, or 3 parts per million (ppm), of hydrogen. After another five-minute cycle, it can get up to 4 ppm. The typical range of hydrogen output for hydrogen water bottles is 1 to 1.6 ppm. This bottle and several others on our list go higher than that.

The only potential drawback is that using hot water in this bottle can damage its membrane. The product has a one-year warranty.

With the touch of a button, your water can have up to 2.5 ppm in five minutes. After another five-minute cycle, it can have up to 4.5 ppm. With a 10-ounce capacity and a weight of just 1.25 pounds, this is a compact hydrogen bottle that’s easy to take on the treadmill or put next to you while lifting weights.

The bottle self-cleans and only needs to be thoroughly washed once or twice a month. It needs to be charged every 5 to 10 uses. The only potential downside is that it can’t take tap water — only filtered water with no chlorine, distilled water, or reverse osmosis water. The bottle also can’t filter chlorine, which can interact with the hydrogen process and potentially damage the device. It comes with a five-year warranty, which is longer than most of the bottles on this list. This is one of the hydrogen water bottles Sirois recommends, because it is from a reputable brand, made from quality materials.

The hydrogen bottle with the highest hydrogen concentration on this list is the Qlife Qcup Max. After one five-minute cycle, it can reach up to 3 ppm of hydrogen, and after two cycles, it can reach up to 5 ppm. This bottle also has built-in SPE/PEM (Solid Polymer Electrolyte/Proton Exchange Membrane) technology to remove harmful gases like ozone and chloride, which is a major plus, but you must manually remove the lid between cycles to release pressure. The preferred water source is distilled, reverse osmosis, or filtered water, but you can use tap water, if necessary. This bottle is made from durable BPA-free plastic and is portable and lightweight. However, it only has an 8-ounce capacity, so you may need to refill it more often than larger models. The battery charges quickly in 1.5 hours and can run around 15 cycles between charges.

While this product boasts a high hydrogen concentration, more isn’t necessarily better. “For most users, a target concentration of 1 to 2 ppm provides a good balance of therapeutic benefit and practicality. Concentrations above 5 to 10 ppm are possible but may offer diminishing returns and are less stable,” Sirois explains.

The H2Life Hydrogen Sport Water Bottle is the best hydrogen water bottle for travel because it’s super lightweight and portable. It takes two to three hours to charge via USB cable and can be powered up easily during car rides or with a laptop. You can use it up to 20 times on a full charge, so it’s perfect for trips when you don’t have access to power. With this bottle, you can get up to 4.5 ppm of hydrogen, which falls in the therapeutic range.

The bottle is made of food-grade polycarbonate. The bottle’s advanced filtration system filters out chlorine and ozone, but you will need to ensure that you have access to clean filtered or purified water to use it. The manufacturer doesn’t specify whether you can use tap water with this device, although it’s generally not advised because mineral buildup can interfere with the bottle’s performance.

The hydrogen water bottle with the longest-lasting value is the Piurify Hydrogen Water Bottle, because it has excellent design features and a lifetime warranty. Not only does it produce between 1.6 ppm after five minutes and 4.1 ppm after 10 minutes — it also retains hydrogen for up to six hours, so you don’t need to drink it right away. This bottle is easy to clean and is made from lightweight, nontoxic, durable plastic, so you can easily use it during workouts or on the go. Like other bottles on this list, it is recommended that you use filtered or purified water in this bottle, but you can use tap water. It will filter out chlorine and ozone.

It’s made from BPA-free plastic, which is safe, although glass is typically considered a safer alternative. This is one of the hydrogen water bottles Sirois recommends because it’s from a reputable brand and is made from safe materials. It comes in three colors: black, pink, or turquoise.

Our pick for the best budget hydrogen bottle is the Aqua Vital Hydrogen Rich Water Cup because it offers a high hydrogen concentration at a very affordable price. It also has an easy-to-use design and is made from high borosilicate glass, which is BPA-free. This bottle offers a hydrogen concentration of 1.6 ppm or 4 ppm, depending on model. It can remove chlorine and ozone from the water, though it does not filter water.

The only drawback is that some users report leakage and issues with durability.
