Is ozone a useful tool in oder control?

I was always told it was. But after reading a page at www.epa.org, now I am not so sure. What are your opinions?
Here is an exert:
Are Ozone Generators Effective in Controlling Indoor Air Pollution? Available scientific evidence shows that at concentrations that do not exceed public health standards, ozone has little potential to remove indoor air contaminants.
Some manufacturers or vendors suggest that ozone will render almost every chemical contaminant harmless by producing a chemical reaction whose only by-products are carbon dioxide, oxygen and water. This is misleading.
First, a review of scientific research shows that, for many of the chemicals commonly found in indoor environments, the reaction process with ozone may take months or years (Boeniger, 1995). For all practical purposes, ozone does not react at all with such chemicals. And contrary to specific claims by some vendors, ozone generators are not effective in removing carbon monoxide (Salls, 1927; Shaughnessy et al., 1994) or formaldehyde (Esswein and Boeniger, 1994). Second, for many of the chemicals with which ozone does readily react, the reaction can form a variety of harmful or irritating by-products (Weschler et al., 1992a, 1992b, 1996; Zhang and Lioy, 1994). For example, in a laboratory experiment that mixed ozone with chemicals from new carpet, ozone reduced many of these chemicals, including those which can produce new carpet odor. However, in the process, the reaction produced a variety of aldehydes, and the total concentration of organic chemicals in the air increased rather than decreased after the introduction of ozone (Weschler, et. al., 1992b). In addition to aldehydes, ozone may also increase indoor concentrations of formic acid (Zhang and Lioy, 1994), both of which can irritate the lungs if produced in sufficient amounts. Some of the potential by-products produced by ozone?s reactions with other chemicals are themselves very reactive and capable of producing irritating and corrosive by-products (Weschler and Shields, 1996, 1997a, 1997b). Given the complexity of the chemical reactions that occur, additional research is needed to more completely understand the complex interactions of indoor chemicals in the presence of ozone. Third, ozone does not remove particles (e.g., dust and pollen) from the air, including the particles that cause most allergies. However, some ozone generators are manufactured with an "ion generator" or "ionizer" in the same unit. An ionizer is a device that disperses negatively (and/or positively) charged ions into the air. These ions attach to particles in the air giving them a negative (or positive) charge so that the particles may attach to nearby surfaces such as walls or furniture, or attach to one another and settle out of the air. In recent experiments, ionizers were found to be less effective in removing particles of dust, tobacco smoke, pollen or fungal spores than either high efficiency particle filters or electrostatic precipitators. (Shaughnessy et al., 1994; Pierce, et al., 1996). However, it is apparent from other experiments that the effectiveness of particle air cleaners, including electrostatic precipitators, ion generators, or pleated filters varies widely (U.S. EPA, 1995). There is evidence to show that at concentrations that do not exceed public health standards, ozone is not effective at removing many odor-causing chemicals.
In an experiment designed to produce formaldehyde concentrations representative of an embalming studio, where formaldehyde is the main odor producer, ozone showed no effect in reducing formaldehyde concentration (Esswein and Boeniger, 1994). Other experiments suggest that body odor may be masked by the smell of ozone but is not removed by ozone (Witheridge and Yaglou, 1939). Ozone is not considered useful for odor removal in building ventilation systems (ASHRAE, 1989). While there are few scientific studies to support the claim that ozone effectively removes odors, it is plausible that some odorous chemicals will react with ozone. For example, in some experiments, ozone appeared to react readily with certain chemicals, including some chemicals that contribute to the smell of new carpet (Weschler, 1992b; Zhang and Lioy, 1994). Ozone is also believed to react with acrolein, one of the many odorous and irritating chemicals found in secondhand tobacco smoke (US EPA, 1995). If used at concentrations that do not exceed public health standards, ozone applied to indoor air does not effectively remove viruses, bacteria, mold, or other biological pollutants.
Some data suggest that low levels of ozone may reduce airborne concentrations and inhibit the growth of some biological organisms while ozone is present, but ozone concentrations would have to be 5 - 10 times higher than public health standards allow before the ozone could decontaminate the air sufficiently to prevent survival and regeneration of the organisms once the ozone is removed (Dyas, et al.,1983; Foarde et al., 1997).
Even at high concentrations, ozone may have no effect on biological contaminants embedded in porous material such as duct lining or ceiling tiles (Foarde et al, 1997). In other words, ozone produced by ozone generators may inhibit the growth of some biological agents while it is present, but it is unlikely to fully decontaminate the air unless concentrations are high enough to be a health concern if people are present. Even with high levels of ozone, contaminants embedded in porous material may not be affected at all.

Well, Ozone may help a little bit, but too much ozone is dangerous to your health. I'd think that an ionizer would help out more.

Yes i agree....negative ion generator is the way to go.......works more efficiently from what i've seen and is safer........

Ozone does work well but use proper ventilation after spraying

Ozone is very effective. It works the same way that peroxside (sp?) Works. Basicall ozone is three oxygen molecues instead of the normal two that you breath. The third oxygen molecule has a very unstable bond and will "explode" when it comes in contact with organic things in the air (which is how you smell, organic stuff in the air hits your olfactory nerve and your brain registers it as a scent) when this explosion ocures the extra molecule will adhere to the organic object in the air. Between the explosion and reatachment the organic matter is distroid. Its much more effective the ion generators.
Now the downside. Both peroxide and O3 don't tell the different between what you want killed and well...yourself. When you pour peroxide onto a cut it kills the skin cells at the cut actually doing damage while sterilizing. O3 does the same by damaging lung tissue. Effective smell managment with a price to make you thing twice.

take some activated charcoal and burie it in the soil of your plants( i assume you mean marijauna). wooks pretty good and its CHEAP you can get where ever they sell aquarium supplies ie wallmart. i got this from a guy at yahooka called kingmotherfukinmidas hes really intelligent it works pretty good. peace

Carbon filters are incredible for absorbing odor if you push air through it on it's way out of whatever area the smell is in. I don't know how well it works for marijuana though. Cigarette smoke was absorbed very well.

carbon filters are excellent as well but cannot compare to the odor destroying capability of ozone. If you need to get rid of smoke smell or to destroy mold in a basement , ozone is the ticket. There are some cheap room cleaners online but you must vacate the area and have no plants or pets present. These units normally come with a timer so you can set it and leave the premises. After about 8 hours of off the O3 will revert back to oxygen and it will be safe to re-enter the premises. I use one so i know they work.

of course if you have plants already growing, do not use it!

Some confusion here - the ozone MOLECULE has three oxygen ATOMS.

Please excuse my ignorance as a newer user of the shroomery but i really fail to see what the big deal is about commenting on an old thread. Seems every time i do this the "thread police" jump out of the woodwork to scold me. Can someone please explain what is wrong with reviving an old topic if i think it is valid and cannot be found anywhere else on shroomery? I assume you will say, start a new thread.. but whats the point? Isnt it better to keep all relevant info in one place? Same way you organize folders on the computer, isnt it better than having the same topic scattered all over? I dont get what the big deal is. Please explain. Thanks

Totally agree, nitrodigital, that puzzles me a bit as well. If a thread is no longer relevant, it should be deleted by the mods - otherwise it can be regarded as part of a useful archive and still available for further comment.

good to see i am not the only one that thinks being hassled about posting to an old thread is ridiculous. This place is about sharing knowledge which should not be discouraged. I agree if the mods determine a topic to be irrelevant they can remove it.

a carbon filter in conjunction with ozone would be the best of both worlds for purifying intake air whatever the application. I've used ozone extensively and i can confirm it is quite amazing at neutralizing contaminants in air, water, surfaces as well as many other organic matters.

Each instance has to be judged for itself. Past posters of old threads might no longer be around to continue the discussion. Old resurrected threads don't always pick up as many new posters joining in and soon die again after achieving little, whereas a new thread is more likely to see action and contributions.
There are 25,000 threads in the EG alone, mods aren't about to go through them and lock/delete any duplicates to ensure we have just one thread per topic.
