One of the most common questions that we get asked is about ozone safety.
You may have read a report by a federal or state agency warning to be careful of the danger of too much ozone.   It is extremely important to understand what these warnings mean.

One must make the distinction that a high ozone level in an UNOCCUPIED ROOM has
absolutely nothing to do with any of the warnings issued for ozone use concerning air purification. 

When you are NOT in the room at the time, it is completely safe to use ozone at any level, as long as you wait until the ozone reverts back to oxygen to re-enter the room, which takes only about an hour or two. 
Since ozone is made up entirely of oxygen it can only revert back to natural oxygen once the ozonation process is completed. Therefore while high levels of ozone are toxic, within a short time ozone reverts back to non-toxic oxygen.  That's the beauty of ozone.  At very high levels it is toxic and kills bacteria, molds, and viruses. Yet unlike chemicals or pesticides it leaves no non toxic residue around which can affect your health.

Our machines are designed to produce high levels of ozone when needed to perform 
High Ozone Shock Treatments  in UNOCCUPIED ROOMS. 

High ozone levels are an absolute MUST to kill bacteria, mold, and have the ability remove strong odors.
Remember unless you can achieve toxicity, in an UNOCCUPIED ROOM, you will NEVER be able to kill mold and bacteria.  The definition of toxicity means to kill. Without toxicity you cannot kill anything.  "Safe" air purifiers, ionizers, even ozone generators can kill very little, if any bacteria or mold. If it is called a "safe" purifier it cannot sanitize entire rooms of mold and bacteria.

Ozone is sometimes very mistakenly referred to as SMOG. In fact Ozone destroys SMOG which is made up of hydrocarbons and breaks them apart on a molecular level.  In fact without ozone we could never get rid of smog!
Ozone is nothing more than 100% pure Oxygen in the O3 form.  It has a very short half life, and quickly reverts back to plain O2 Oxygen.

Ozone is made by nature and is all around us. Ozone concentrations of 0.05ppm are within most recommended safe exposure levels for air purification levels. 

It is important to remember that when using ozone for air purification, control over the ozone level is the most important feature. 

We've designed our air purifying Air-Zone Ozone Generators to have the most control over the ozone output as compared to any other ozone generator made.

The "burst timer" built right into our smaller machines is designed to limit the amount of ozone to very low levels for use as an air purification device. 

Our smaller machines XT-120 - XT-800 can regulate the generator to only produce ozone for as little as 2 seconds out of a minute. This allows only very low levels of ozone to be present in a room.  That fact alone makes our units some of the safest on the market. 

Our smaller machines XT-120 - XT-800 have burst timers to limit the ozone production so that they can be used as low ozone level air purifiers that operate within "safe" levels. 
Yet these same machines can also perform high ozone treatments in small to medium sized rooms.

The right amount of ozone to use is the level that will eat up the contamination and cause the ozone to naturally self destruct.

Ozone is basically self limiting. When the ozone level reaches to high a level it begins to irritate sinus passages, give you a sore throat, and possibly even a headache. 

Many people are worried about using an ozone generator because it can produce higher than the recommended exposure levels.

If you have ANY question about ozone safety you can simply use ozone when you are not in the room, and set the timer to turn the unit off before you re-enter the room.
You can sanitize the room before you enter it.  That way you will have NO exposure to ozone.
No other type of air purifier or ionizer can do that.

We also offer different types of ozone sensors, and cards to further monitor the ozone level if needed.
 

Ozone Detector Cards Eco Badge® Ozone Detector Cards provide a low cost alternative to ozone meters for ensuring that an environment is within accepted safety standards when using an ozone generator, or any other place where ozone levels are desired to be monitored. These patented ozone test cards were originally developed for NASA. Each kit contains two separate, one hour tests in vacuum packed pouches. A colormetric strip is included which enables the user to read, and interpret each test. These test cards are very easy to use. Just open up one of the sealed pouches and take out the test card and tape it to a wall or any other convenient surface. After one hour you match the color of the card to the colors on the colormetric strip to determine the ozone level.  They couldn't be any more easy to use. The tests give the user an accurate reading from 40 to 240 parts per billion of ozone. While these cards are not a substitute for real time ozone sensing, they do offer a  an alternate low cost, temporary solution. For constant monitoring of ozone levels we recommend the EZ-1X Ozone Sensor. Ten Ozone Detector Test Card Kits Price $39.99 For constant real time ozone level monitoring we recommend our EZ-1X Ozone Meter. The EZ-1X Ozone Sensor is meant to monitor ozone levels in occupied spaces.  It can be used to monitor ozone levels in a home, restaurant, bar, or in any other space where ozone is meant to be kept at recommended level around humans & animals. It constantly monitors ozone levels by displaying them on a multi colored bar graph.  Accurate Range from a range of 0.02 - .14 ppm.  Bar graph Display:  Green - Normal levels Yellow - 0.05 ppm Moderate levels Red - 0.1 ppm High levels CLICK HERE to learn more about the EZ-1X Ozone Sensor.

Ozone has been documented for over a century now, so quite a lot is known about it. 

OSHA - Occupational Safety and Health Agency has stipulated that the safe allowable level of residual ozone is .08 ppm. This is supposedly based upon the historical safety of ozone. 

Note that this permissible level is for continuous exposure throughout an entire 8 hour day for 5 days a week.

No Federal or State agency can agree an what the maximum level of ozone exposure should be, so there is no standardization in maximum permissible ozone levels.

That signifies these numbers are arbitrary, meaning they are not really sure of what a maximum sustainable ozone level should be.

Since excess ozone gives off an unmistakable strong "bleach like" odor, one always know if too much is present in the air.

In other words before ozone could possibly have any unsafe effects, a person would be greatly offended by it's bleach like odor.

Ozone is safe to use in occupied areas because we notice it's unpleasant odor at very low levels and then have the ability to turn it down.

Ozone generators, when used correctly will not exceed government guidelines for continuous safe exposure.  Even if they are used incorrectly the ozone will provide its own protection, since ozone warns us if its level is too high in a manner similar to smoke in a room. 

Precautions should be taken, however, because the nose can loose it's ability to sense the ozone after a sustained period of time. If one senses a headache or sore through it may mean the ozone level is too high.

The fact remains if the ozone level is much higher than is recommended to be consider safe,  it would become so pungent that anyone could sense it. 

Ozone does this by becoming so offensive at high levels that we would not be able to stay in the environment for more than a very short period. 

This is much like what would happen if we entered a smoke filled room. 

However, while smoke may harm us, research has proven that such a limited exposure to what is still considered low level of ozone, that would it irritate us will have no serious long term affect on us.

No one has ever claimed a worker's related illness resulting from ozone exposure.
