effect and safety of
Deodorizing / sterilizing

What is ozone?

It is a safe and environmentally friendly substance
with excellent deodorizing and sterilizing power

The ozone layer exists around 25km above from the ground
and protects humans from ultraviolet rays.

Ozone is a gaseous substance consisting of three oxygen atoms.

Oxygen molecules floating in the sky (O2)
Decomposed by ultraviolet rays into oxygen atoms (O)
Bonds with other oxygen molecules
Become ozone (O3)

Ozone has the property of returning to oxygen (O2)
The released oxygen atom (O) is
Causes an oxidation reaction with surrounding substances.

Reacts with offensive odors and harmful bacteria
act as deodorizing and sterilizing effects.

Ozone does not residue.
Eco-friendly and
Clean substance.

Unique points / effects Of ozone

Give 5 effects by Strong oxidizing power

1. Deodorization

Has a great deodorizing effect
By using ozone water directly to the source of the odor.

2. Sterilization

Sterilization in a short time
Suppresses decay for a long time by ozone water.

3. Sterilization of airborne bacteria

Sterilize airborne bacteria in the workplace
It also deodorizes at the same time by ozone air.

4. Remove mold and slime

Sterilize mold fungi
Mold removal, remove slime, easily with ozone water.

5. Pest repellent

Pests are hard to approach, create a clean environment with full using of ozone water / air.

Special mechanism of ozone effect 1


Odor caused by spoilage of food
Main causes are amines, ammonia, sulfides, etc.

These are caused by
self-decomposition by enzymes of the food itself
in the process of protein decomposition by microorganisms.

Ozone water which has dissolved ozone deodorizing through these 3 processes. 


1. Cleaning of odorous substances
2. Sterilization of microorganisms
3. Oxidative decomposition of odorous substances

Experiment 1

Deodorizing effect test by ozone water (Our research)

Test condition

  1. Make a rotting odor
    Place the squeezed fish juice on the Schale/Petri dish
    Leave in a container at 60 ° C.
  2. Measure changes of
    1. number of bacterial
    2. odor intensity
    after treat schale as
    -Rinse the rotten-smelling schale twice with tap water
    -Leave the schale after cleaning in the container at 60 ℃ again.
  3. Do the same with ozone water


  1. Ozone water has high sterilizing power compared to tap water.
  2. Less bacterial growth, long-lasting deodorizing effect of sterilize with ozone water.

Odor level / 6-step intensity display

Odor intensity Contents
0 Odorless
1 Finally perceptible odor
2 A weak odor that tells you what the odor is
3 Easily perceptible odor
4 Strong smell
5 Very strong smell

Special mechanism of ozone effect 2

Removing bacteria

Only destroyed Intracellular enzyme and sterilized but pass through the bacterial cell envelope (walls and curtains)

Has a strong oxidizing action of oxygen (O) generated during decomposition
Direct damage / destruction / decomposition of bacterial cell walls
Killed and sterilized by dissolving intracellular components.

Fast sterilization, difficult to generate resistant bacteria is available.

"when hand-washed"
By mouse or hamster.

Drink test not conducted by human body.
Do not drink ozone water.

Effects on eyes and skin by Ozone water

Safety confirmation by animals(Japan Food Safety Analyze Center)

Assumed behavior Test Result
If drink continuously Repeated tendency test (mouse) no problem
If gargle Oral mucous irritation test (hamster) no problem
Effect on wounds Colonization inhibition test no problem


Skin irritation test (in-house test)

Effects on the skin In-house monitor test (24 people, 3 months) no problem

Ozone concentration in the work environment

  1. Ozone concentration in the work environment
    0.1ppm or less (8 hours a day, 40 hours a week light work) Recommended by Japan Society for Occupational Health
  2. No entry during ozone air is blowing out
    Ozone concentration Exceeds the allowable during ozone air is blowing
    Make sure there are no people before usingDo not enter the room for 2 hours after the end of blowing.
  3. Volatile gas from ozone water
    Ozone concentration rises when used for a long time in a narrow place.
    Ventilate often.

    Experiment with the effects of ozone by
    General kitchen utensils
    No significant deterioration / corrosion promotion
    By using ozone water

    Rubbers and metals
    May deteriorate faster or rust if you put it
    Near the ozone air outlet


  5. Use for food cleaning
