According to a recent study by Nara Medical University, the new coronavirus can reduce the risk of virus by about 1/10 to 1/100 by exposing it to a concentration of 1 ppm for 60 minutes.
Based on the above, please use our ozone concentration calculation tool and select a model with a theoretical value of 2 ppm or more within 60 minutes.
*The ozone concentration calculated with this tool is a theoretical value, and in most cases the actual ozone concentration will be about half of the theoretical value due to self-decomposition of ozone and reaction with odorous substances and bacteria.
Therefore, if the theoretical value of 2 ppm or more is calculated, the actual ozone concentration will be approximately 1 ppm.
*Our ozone generator is not recommended for continuous operation for more than 60 minutes to prevent troubles such as breakdown.
For the above reasons, select a model with an ozone concentration of 2 ppm or more within 60 minutes.
Although there are methods such as alcohol and hypochlorous acid as measures against the new coronavirus, there are three advantages of ozone.
For the above reasons, it is used in various places such as accommodation facilities, medical facilities, schools, restaurants, and offices.
Yes, there is.
The other day, a team at Nara Medical University inactivated the new coronavirus with ozone.
The contents of the announcement are as follows.
・Inactivates from 1/1,000 to 1/10,000 with a CT value of 330 (55 minutes exposure at an ozone concentration of 6 ppm)
・Inactivates from 1/10 to 1/100 with a CT value of 60 (60 minutes exposure at an ozone concentration of 1 ppm)
ppm x time (minutes) = CT value.
For example, if 1ppm x 120 minutes, the CT value will be 120.
The focus is on how much anti-virus measures should be taken. For example, CT60 is raised in the evening, so it can be said that the risk of virus is reduced to about 1/10 to 1/100.
In order to take thorough measures, it is necessary to expose to high concentration of ozone for a long time, but if it is done to that extent, it will have harmful effects.
For example, it can corrode iron and rubber and damage leather products and ornamental plants.
If you do not make it high concentration (5ppm or more), you do not need to worry about it.
You can use this tool to calculate the arrival time to a CT value of 60 inside a room.

We have calculated the effective space of each model for each purpose and made a table, so please refer to it.
Effective space for each purpose when using each model for 60 minutes
|equipment||Deodorizing purpose||Antivirus purpose|
|Ozone crower||Up to about 35㎡||Up to about 20㎡|
|Australian Clear 2||Up to about 60㎡||Up to about 30㎡|
|Australian Clear 3||Up to about 110㎡||Up to about 60㎡|
|Ozone cluster 1400||Up to about 260㎡||Up to about 130㎡|
*Assuming a ceiling height of 2.5 m
*Ozone concentration when only one piece of equipment is used
*Calculated assuming a theoretical ozone concentration of 1 ppm for deodorization and a theoretical ozone concentration of 2 ppm for anti-virus purposes
The ozone generator has very low power consumption and is an eco-friendly machine.
For example, our high-end model Ozone Cluster 1400 only costs about 1 yen (*) a day for electricity.
*If the daily usage time is 1 hour
Ozone water generator consumes more power than ozone generator.
This is because the ozone generator of Ozone Mart is an electrolysis method, which has a very high generation efficiency.
If you want to calculate the electricity bill when using Ozone Mart products in detail, please use the electricity bill simulator below.

Yes, it is also effective in controlling pests.
However, ozone has no insecticidal effect.
It can be used as a pest control measure because ozone deodorizes bait and fellow odors to prevent pests such as cockroaches from approaching.
Even if you don’t do anything, the pump sucks 8 L/min from the oxygen input port, so it is okay if you adjust the oxygen amount according to the ozone concentration you want to generate.
However, be careful that the pressure of the oxygen cylinder is 10 Kpa or less.
Depending on the water temperature and quality, 2 liters of water at room temperature will give 1.0 ppm in about 4 minutes.
With 10 liters of water, it will be 1.0 ppm in about 7 minutes.
Also, when ozone water is generated, undissolved ozone is aerated into the air, so be sure to do so in an environment where there are no people.
It is designed to withstand up to about 10 Kpa.
You can calculate the CT value 60 arrival time when using Ozone Mart products.
Please see here for the mechanism of this calculator .
Calculate CT60 arrival time
Correction value considering natural decomposition of ozone and environmental factors
|CT60 arrival time||** minutes||** minutes|
|Ozone concentration when CT60 is reached||** ppm||** ppm|
The CT value is a numerical value that represents the contact strength between ozone in the air and substances in the air (odorous substances, molds, viruses, etc.) .
The larger this value, the greater the amount of contact between ozone and substances in the air, and the greater the deodorizing and sterilizing effect .
Below are three cases where the CT value is 60.
Although the ozone concentration and contact time are all different in these three cases , the CT values are the same 60 , so the effect is the same in all three cases .
Table 1. Example of CT value of 60
|1.0 (ppm)||60 minutes)|
|0.5 (ppm)||120 minutes)|
|5.0 (ppm)||12 (minutes)|
In the example in Table 1 above, the calculation is based on the assumption that the ozone concentration in the room is constant from start to finish.
For example, in case 1, it is assumed that the room was 1ppm from beginning to end.
However, the ozone concentration when actually deodorizing and sterilizing using an ozone generator is not constant.
Starting from a state where the ozone concentration is extremely low ( * ), ozone generated by the ozone generator gradually increases the ozone concentration over time.
* The concentration of ozone in the atmosphere is around 0.005ppm.
Therefore, in order to calculate the CT value when using an ozone generator, it is necessary to take into consideration the concentration that changes over time.
Let’s take a look at the calculation method when an ozone generator is used, taking the ozone generator Ausley Clear 3 which is used by the most customers at Ozone Mart as an example.
Floor area , ceiling height Using the O Three clear 3 in a room at, per second in theory by ozone The concentration will increase.
At this time, if the ozone concentration after seconds is , the change is as shown in Table 2.
Table 2. ozone concentration after t seconds
(O Three clear 3, floor area , ceiling height )
Since the ozone concentration changes every second, the CT value also changes every second.
For example, since the ozone concentration 1 second after starting to use Ausley Clear 3 is , the CT value for 1 second at that concentration is
* Since the unit of time used for CT value is (minutes), it is necessary to multiply by when calculating the CT value per second .
I started using O Three clear 3 the CT value of every second in If you, the change will be as shown in Table 3.
Table 3.CT values per second after t seconds
One second later
2 seconds later
After 3 seconds
after t seconds
(CT value per second)
Therefore, the cumulative CT value and starting using Ausley Clear 3 is the sum of the CT values every 1 second, and is as follows.
When this value (cumulative CT value) reaches 60, is the CT value 60 arrival time.
This example (O Three clear 3, floor area , ceiling height ) For, the ozone concentration of is
Therefore (*See Table 2), the cumulative CT value will be as follows.
From this, the time that satisfies the following equation becomes the CT value 60 arrival time, and this computer also calculates the arrival time by actually solving the following equation.
Deodorizing the dog trimming lab is relatively easy.
If the area is about 30 square meters to 50 square meters, if you use Ousley Clear 3 to release ozone for about 30 minutes and leave it for 1 to 2 hours, it will be almost odorless. Can be
If the original odor is strong and does not seem to be removed by itself, repeat the same operation 2-3 times. This will eliminate the persistent odor.
Please note that when releasing ozone, there should be no humans or animals.
Inhaling ozone for a long time may cause sore throat and headache.
The higher the ozone concentration, the higher the deodorant/bactericidal effect, but operation at an unnecessarily high concentration is not recommended for the following reasons.
Not good for the body
Shortening the life of ozone generators
In addition to ozone concentration, there is another point to be aware of for effective deodorization and sterilization by ozone.
It is “the time when the odorant and ozone are in contact” .
No matter how high the ozone concentration is, if the odorant and ozone do not come into contact with each other, deodorizing and sterilizing effects cannot be expected.
Strength of effect = (Ozone concentration) (Time of contact with odor substance)
In this way, the strength of the deodorizing/bactericidal effect of ozone is determined by the product of (ozone concentration) and (contact time).
Let’s look at a concrete example.
Ozone concentration: 2.0 (ppm)
Contact time: 15 (min)
Strength of effect = 30
Formula: 2.0 (ppm) 15 (min) = 30
Ozone concentration: 1.0 (ppm)
Contact time: 30 (min)
Strength of effect = 30
Formula: 1.0 (ppm) 30 (minutes) = 30
Ozone concentration: 10 (ppm)
Contact time: 1 (min)
Effect intensity = 10
Formula: 10 (ppm) 1 (min) = 10
Note that the ozone concentration in (Example 2) is half the ozone concentration in (Example 1), but the strength of the effect is the same as in (Example 1).
This is because the contact time (example 2) between ozone and the odorous substance is twice as long as that of (example 1).
Also, in (Example 3), the ozone concentration is overwhelmingly higher than in the first two, but the effect is only 1/3 of 10.
Because the contact time is extremely short.
Increasing the ozone concentration is easy.
If you execute the following, the ozone concentration will surely increase.
Keep it closed
Use an ozone generator with high production capacity
Prolong contact time
In the time of contact with the odor substance do you tempering to increase.
Circulate room air (ozone)
By circulating the air in the room, ozone continues to fill the entire room, which increases the time in contact with odorants in the room.
Specifically, take the following method.
Move the circulator at the same time
Air conditioner ventilation mode
Since ozone is heavier than air, it tends to accumulate in the lower part of the room.
The combined use of a circulator is very effective for increasing the contact time between ozone and indoor odorants.
In addition, with products that do not have a fan for ozone diffusion, such as the Ausley Clear series , it takes time for the generated ozone to reach the entire room.
Even when using such an ozone generator for deodorization and sterilization, a higher deodorization and sterilization effect can be expected by using the circulator together.
Ozone Mart recommends the following operations to deodorize and disinfect.
* “Contact time with odorant” and “time to operate ozone generator” are different.
The ozone generator can be turned off when the appropriate ozone concentration is reached.
Contact time with odorant
be used in combination
Contact time with odorant 3-6
Effective when used together with a circulator
You can know the approximate ozone concentration without using an ozone concentration meter.
We have prepared a calculation tool when using Ozone Mart products, so please use it as a reference for selecting the appropriate product.
** minute ozone concentration theoretical value of the later ** ppm is
In most cases, the actual ozone concentration will be about half of the theoretical value due to self-decomposition of ozone, reaction with odorous substances and bacteria.
Depending on the water temperature and water quality, 2 liters of water can generate ozone water up to 1 ppm in about 4 minutes and 10 liters of water in about 7 minutes.
If it is used in the room, you can put the equipment in the room and operate it without any problem.
However, it is recommended to attach the tube when using it in a narrow space such as a toilet or car.
There are two reasons.
First, since ozone uses oxygen as a raw material, it is more efficient to install Ousley Clear 3 outdoors and to send ozone through a tube into a narrow space rather than to install Ausley Clear 3 in a narrow space. is.
The second reason is that if the body inhales a high concentration of ozone, it may cause a malfunction.
For the above reasons, it is recommended to install the tube when using in a narrow space.
