NOERDEN LIZ Smart UV Thermal Bottle Review

Design

The NOERDEN LIZ water bottle looks like a “normal” stainless steel water bottle and you probably wouldn’t be able to tell that it contains some “smarts” just by looking at it. There is also a rubber anti-skid bottom to help prevent the bottle from sliding around on a table. A small NOERDEN logo is located on the front of the bottle near the bottom.

The lid of the LIZ bottle contains the “smarts” with touch controls, LED ring light, and a UV sterilization LED on the bottom that goes in the bottle.

The bottle is fairly narrow so it should fit in most cupholders, making it convenient for taking on the go.

Performance

The bottle can be turned on and off by touching and holding the touchpad on the top until the LED flashes white.

Once the bottle is filled with liquid, double-tap the touch control to activate the UV sanitation LED. The lid will pulse while the sanitation process runs, which lasts about 5 minutes. The company claims that it can remove up to 99.9% of bacteria and viruses, but I don’t have the means to verify this. It’s also important to note that this will only be effective on clear water as any colored liquids will prevent the UV-C light from penetrating it thoroughly.

You can check the temperature of your beverage at any time by tapping the touch control once. The lid’s LED will light up red when the liquid is above 140 degrees Fahrenheit, yellow when between 98 and 140 degrees Fahrenheit, and blue when below 98 degrees Fahrenheit.

The bottle will also remind you to drink every two hours by flashing a blue or yellow light (according to the temperature) every 2 hours. This is handy as I’m guilty of not drinking as often as I probably should, so it’s nice to have the bottle on my desk near my monitor where the LED will catch my eye when it flashes. The 2-hour timer resets every time you remove the lid or if the beverage is above 140 degrees Fahrenheit.

I first thought the bottle was defective as I filled it with water and double-tapped the touch control on the lid, but the LED flashed red several times. I then found the note in the manual about leaving the lid off of the bottle for about 10 minutes to restore normal operation. I did this and it worked ever since.

Battery

The manufacturer states that a single charge will last up to a month if you only run the sanitation process once per day. The included charging cable is a Micro USB cable with a proprietary magnetic connector attached to the end. You’ll want to make sure not to lose this connector as you likely won’t find it available at your local store. It’s about $5 to purchase a replacement charging cable from NOERDEN’s website.

All functions are disabled while the lid is charging, so you can not run the sanitation process while the charger is connected. It takes about 2 hours to recharge the lid.

Differences between the LIZ and the LARQ

I also have the LARQ water bottle which operates similarly: the lid contains a UV-C LED on the bottom of the lid that shines down on the water in the bottle. The LARQ sanitation process only runs for 1 minute normally (with an option to run for 3 minutes), but it also runs a short sanitization cycle every two hours to continually sanitize the water. The NOERDEN LIZ will flash to remind you to drink every 2 hours, but it does not automatically run a sanitization cycle.
