Odor control

We're just getting our first crop growing and getting ready to go the bloom room. We have an ozonator but have no clue as to how long you run one, or do have to have a meter to read the amount of ozone in the air? Thanks for the help.

Is Ozone Safe?
Although some groups claim that ozone is harmful, proof of its safetiness and usefulness at moderate concentrations have prevailed in hearings before the FTC. Plus, millions of ozone air purifiers have been sold in the United States over the years, but there are no specific cases where an ozone air cleaner has been linked to any kind of harm or injury.

Why ozone is mistakenly give a bad name.

Ozone can only be harmful only when occurring at extremely high concentration. However, at lower levels it serves as a powerful purification element without harmful side effect. It's also a powerful purification agent in large doses, but can also act as a lung irritant in higher concentrations.

One example of this is an ozone alert, which is a warning to the public when outdoor levels of ozone reach a high level. Ozone alerts usually occur in already polluted areas where there is a high conctration of hydrocarbons in the air (pollutants that result from smokestack and vehicle exhaust pollution).

Why ozone is associated with smog.

In these cases though, the reason ozone concentration hits high levels in polluted areas is due to the fact that they are a byproduct of the sun rays coming in contact with hydrocarbons. This is the sun's way of trying to
neutralize the pollutants. In which case, where the hydrocarbon level is very high, the ozone concentration also becomes higher.

However, it is much easier to measure ozone concentrations than it is hydrocarbon concentrations, so ozone gets the bad name, even though it is the hydrocarbons that are the real problem. Most ozone air purification systems, including the PureWise and LifeTech models, are designed to produce ozone in levels of less than 0.04 parts per million (OSHA recommends less than 0.1 ppm, see chart below).

But as is the case with just about every other chemical element, ozone has its range of effects, from no effect, to useful effect, to hazardous effects.

Another good example of this is table salt, which provides essential fortification for nerve cells and the kidneys, and prevents heat stress disorders at lower concentrations. At higher levels though, salt can result in hypertension and cardiac failure.

Negative Ion and Ozone Air Purifier Products

Ozone Levels and their Effects
(ppm = parts per million) 0
ppm Most indoor environments - windows closed
.001
ppm Most indoor environments - windows open
.003-.01
ppm Low range at which average person can smell ozone
.02-.05 ppm Range in which ozone occurs in healthy outdoor environments. Typical level produced by ozone generators.
.04 ppm IPS air purifiers (approx.) when operated according to instructions
.05 ppm Maximum recommended by ASHRAE in an air conditioned and ventilated space. Also maximum under FDA regulation for ozone.
.1
ppm Maximum allowed by OSHA in industrial work areas.
.2
ppm Prolonged exposure of humans in occupational and experimental conditions produced no apparent ill effects.
.3
ppm Level at which nasal and throat irritation will first appear.
.5
ppm Extended exposure could cause lung edema. Smog alert 1.

Thank you for the information on what the level is supposed to be. Unfortunately, that did not answer my question of the length of time for the ozonator's useage. I tried a search but came up with nothing. That's why I'm asking in the forum.

Did you search the web or the site? I apologise if this sounds kind of snappy, but the above information came from the first page Excite brought up when fed "ozone".

From the list I'd say if it is working properly it can run 24/7.

Wal-Mart sells ozone alarms and sometimes meters. I wouldn't worry about it though as long as you have good ventilation and air exchange.

Thanks ButterflyDreams
The computer and growing are both new to me. So we will try and try again until we get all of this right. I appreciate the info you have given. There is so much to learn and hate the failures. The guy we got the clones from to start growing to begin with becomes very upset if any of his "babies" die. So we are trying to do all of it perfectly, that is, if that is possible. :-) Thank you again. Di
