Did you know that

tap water alone can disinfect and

deodorize over 99%

of germs and viruses?

Just pour your household tap water into ULAS

O3 and turn on the switch.You will have the

safest and most potent ozone water on earth.


ULAS has succeeded in developing ozone water

spray that can quickly generate high potent

medical grade ozone water for home use with a

touch of your finger.


What is

ozone water?

Ozone water is a state in which ozone (O3) is

dissolved in water (H2O). Its main components

are water and air. Unlike ozone gas, it is

non-persistent and safe.


Its excellent oxidizing power characterizes ozone

and has the strongest oxidizing action next to

fluorine in the natural world.

It has been used in many different areas to

protect our lives and the environment.

Ozone has been attracting attention as the most

potent and environmentally friendly disinfectant

and deodorant as it returns to oxygen and

water once its work is done. It is friendly to

both the human body and the environment.


So why has it not been widely known and had

not been put into practical use at home?


It was mostly due to another characteristic of

ozone water.

As soon as ozone water exposed in the air,

ozone water begins to decompose, and

concentration of ozone in ozone water decreases significantly becoming less potent in seconds.


For example, even if the concentration at the

time of generation is 3 ppm, it will lose about

1.5 to 2 ppm by the time it reaches the object

about 10 cm away from the spray port.

Furthermore, ozone is easily affected by

humidity and the room temperature.

So, if the concentration at the time of generation

is 3 ppm or less, complete sanitization and

deodorization may not be possible, as the

scientific study suggests 1ppm or more is

required to eliminate bacteria and viruses.

Therefore, the concentration of ozone in the

ozone water should be more than 4ppm if one is

expecting to put a full potent of ozone water to

work at home.

This is where ULAS O3 will come in handy for

safe use at home.

The ULAS O3 series can generate ozone water of

5ppm or more by the unique technology

developed by ULAS.

If the ozone water is sprayed at 5ppm from the

ULAS O3 to the area you want to sanitize or/and

deodorize, and it will reach the target while still

maintaining a concentration of 3 ppm or more,

more than enough to inactivate bacteria and



The ULAS O3 series incorporates this unique

technology into a small, easy-to-use, handy-type

spray system (a utility model patent acquired),

making it easy to use in any place and any part.

Is ozone water

effective against

the new coronavirus COVID-19?

When ULAS had started the development of ULAS O3 seven years ago, we did not anticipate the emergence of COVID-19

There are various kinds of viruses, but the basic structure is the same.

The nucleic acid that is basically a gene is at the core, and it is wrapped in a protein envelope to protect its surroundings.

ULAS O3 destroys the protein envelope of the virus instantaneously, exposing the gene in the core, thus inactivating the virus.

ULAS will announce the inactivation verification results of various viruses on this ULAS official website, which is constantly updated.


Humankind has been protected by Ozone

since the beginning

of time.

Ozone layer has

been absorbing the


ultraviolet rays

emitted from the

sun even before we

arrived on this



About 100 years have passed since the discovery of ozone water.

Looking back at the history of humankind, we

have been challenged by various deadly viruses,

but each time we have managed to overcome

the hardship by listening to our wisdom.

In 2020

Humankind has entered the new way of life, the New Normal.


"Let us be

protected by ozone again"
