 NANZA Tl;dr 

Think water carbonator, but like, for your oral care. Okay, that was a bad comparison. The OENKLEN is a mouthwash contraption that turns regular H20 into Ozone water in a matter of seconds. Ozone water is the stuff used at the dentists to sanitize your teeth when you’re under the light. But now, it’s available for home use and has the potential to improve how you take care of your teeth by tenfold. Are these oral magicians on their way to stealing the jobs of dentists?


What’s special about Ozone water?

Ozonated water is created by adding an electrical current (electrolysis), by which diatomic oxygen molecules are separated from one another. Individual oxygen atoms combine with other O2 molecules to form ozone (O3). Cute. It’s also organic, and waste-free. 


Ozonated water has anti-bacterial and anti-inflammatory properties. It’s typically used for disinfection purposes like treating wounds and oral care such as cleaning cavities, soothing toothaches, and teeth whitening. Interestingly enough, it’s also used to eliminate bad odor from fabrics, and washing fresh products like fish and meat.


Sterilization in 5 Seconds 

Not only is the ozone mouthwash generated in just seconds from your very own sink.

Disinfecting 99% of germs in a shorter time than you can say “Oh crap, it’s time to go to the dentist”.

Key Benefits

- Prevention of cavities

- Freshening breath

- Alcohol- free

- Easy use for all ages

- Patented Electrolysis Tech

- No irritation


More Effective Than Your Current Routine  

If you’re consistent with your brushing, use mouthwash and use oral spray religiously but still not satisfied with your oral health, Ozone can be applied in a number of ways:


- Sterilization for your toothbrush

- Sterilization for your tongue

- Get to hard-to-reach areas (great for those who wear braces!)

Visibly Reduced Plaque

The OENKLEN team have provided results with approval from the SGS. 

Custom 3 Mode APP for Management

Select the symptoms that you’re experiencing, and the OENKLEN App will provide a synchronized routine to Daily Clean, Deep Clean, and Flossing modes.



As mentioned in our introduction to ozone water at the top of our review, ozone water can be used in a number of ways. This device in particular has been recommended for external use too! ​

Is It Safe?

OENKLEN is FDA approved. While inhaled ozone is when ozone gas is breathed in, and it can be harmful to the lungs, ozonated water is safe when used as directed. 


The team also states that Ozone neutralizes acidity in the mouth, therefore it is able to kill the bad bacteria, but leaves the good bacteria. Therefore you don’t need to worry about it eradicating oral bacteria that's good for you. 

I know we’re not the only ones who had this thought. But, is it safe to drink? If you… you know. Swallow it. Luckily, the FDA notes ozonated water as safe when consuming and coming into contact with food. That’s not to say, make it an addition to your afternoon cocktail.

Product Lifeline

It supports 800 hours of use. They break it down in theory: Product Lifetime”If you use this machine 5 times a day, theoretically, it can work for more than 20 years. Nevertheless, the actual lifetime depends on the frequency of use.”

 What We Love 

1. It Adapts To Whatever Water Quality You’re Using

No matter where you are in the world, OENKLEN does the job as long as you have access to water. No more refilling your dental irrigator with mouthwash (and risk it getting clogged)! It also allows you to monitor the ozone concentration in real-time. So you know if you’re doing the job right. Plus it gives you a reason to divulge into that chocolate bar you’ve hidden in the freezer. 


2. No More Gatekeeping!

In the past, it’s been difficult to source ozone water due to the finicky methods to make it right. It needs to be the right concentration and it decomposes super easy! OENKLEN can monitor ozone concentrations quickly. Stable, reliable and effective. It's getting easier and easier to do eveyrhting at home now...

 Is it Worth it? 

The OENKLEN is a great option for those who dislike conventional mouthwashes for whatever reasons. Whether it’s the harsh sensation or flavours. Not only does this product have use for oral care but it can also be used for sterilizing fruits and veg, children’s toys, hands, oral care for pets and disinfecting pet supplies… It can also be used as a deodorant. Yes you read that right.  So if all else fails, you’ve got options. It’s rare that we have such a skewed opinion about Kickstarter products, but we think this could be a keeper. Only qualms that other backers have voiced is the legitimacy of the creators. Oh boy, we sure do hope they deliver. In both meanings.
