I am suggesting you abandon the idea of using a mask and filter all the air in the vicinity of yr bod. All the skin absorbs and eliminates, too. Much better to create a bubble of safe air.
Try googling air filter+HEPA and/or air cleaner+ozone and we can discuss further here. I am reviewing this too, but not finding enough time to do the research.
Another option would be to go to Debra Lynn Dadd's website. She has MCS and has made a career of making recommendations on many stuff that can help us.
Please report back and share what U find!
BTW, what I use now are some very old used and nearly free alpine/echoquest filters for ozone and two diff used carbon/HEPA filters. Craig's list and free stuff online, local classified good sources if income is more of an issue than time.
I do not recommend alp/echo unless U figure out how to keep ozone and get rid of the ionization. Currently am working on this in all my copious spare time, LOL!!!!!!
I almost feel like I should post this seperately, but since the subject came up: I don't recommend the use of ozone generating devices. Ozone is a indoor air pollutant and irritant that should be stayed away from. There are other devices and building systems that can help to reduce exposure to chemicals or situations that lead to off-gasing. For some unbiased information on ozone see a few sites: http://www.arb.ca.gov
and the EPA's http://www.epa.gov/03healthtraining.
The last link will take you into a course style review of the source and formation of ozone, effects of exposure, and it addresses typical patient questions and clinical scenarios in relation to ozone exposure. Some of the information is a little doctor-ish or consultant-ish, but it really does provide some very interesting information on this topic.
Musicman, are you looking to reduce exposure in the workplace or in your home? If you are in your home there are numerous systems that can help and professionals that can consult you through some changes to reduce exposure to chemicals and off-gasing of building components and content materials.
There is a wide divergence of opinion regarding ozone. According to many, the gov't sites you recommend are NOT the reliable sources that you apparently consider them to be. Of course, neither are the site of those selling ozonators!!!
There is definitely a risk from being chronically exposed to too much ozone. It has irritated my lungs temporarily if I have spent many hours in a room with an ozone generator set too high. The solution is to TURN IT DOWN! Unless one is VERY WEALTHY, operating HEPA/carbon filter/s 24/7 is not a sustainable expense. Ozone works for minor to medium duty odors, and the others are affordable if for emergency use only. Those with severe asthma or something like COPD would need to be much more cautious than most in order to use ozone, and may decide the extra expense for the other filters is worth it in their case.
However, in the case the setting was commercial. There are high power ozone cleaners that can briefly supple a dose of ozone to clear the air whilst the space is not occupied. They are used regularly in fire and flood remediation. Some of these are also able to supply a safe lower background supply as well.
A tolerable background dose of ozone as well as HEPA/carbon filters is a very effective combination. The ozone generator is MUCH cheaper to operate, so it is on 24/7. When there is an especially bad event, I add one or two HEPA/carbon filters for the duration of the event. This procedure has helped me survive a neighbor who burns toxic trash, leaving the smoke to accumulate in my yard and seep into my home. This has changed horribly stinky and absolutely intolerable to absolutely fine, no smell, no symptoms. Previously, I would have had a migraine within 20-30 minutes of when the smoke started showing up, even if i were sheltering in a closed house!
So, if one uncritically accepts the gov't party line, use HEPA/carbon filters only and incur an extra 3-6 hundred a year or more in expense. If you can not or do not want to do that, the option I mentioned works and is safe for most, if not all.
BTW, are you just passing on second hand info, or have you actually used ozone b4????
I am a four-time, board-awarded indoor environmental consultant with sixteen years in the industry. I apologize if I offended you, but there are tons of resource materials that have lead organizations and governments to educate and make policies to change public perception and practice in relation to the use of ozone use as a 'air purifier'. Ozone is a source of indoor air pollution. In another of the EPA's studies and releases on "ozone generators that are sold as air cleaners"(www.epa.gov/iaq/pubs/ozonegen.html) there is a lot of good resource materials that can be considered unbiased. "There is a large body of written material on ozone and the use of ozone indoors. However, much of this material makes claims or draws conclusions without substantiation and sound science. In developing Ozone Generators that are Sold as Air Cleaners, the EPA reviewed a wide assortment of this literature, including information provided by a leading manufacturer of ozone generating devices. In keeping with EPA's policy of insuring that the information it provides is based on sound science, only peer reviewed, scientifically supported findings and conclusions were relied upon in developing this document." (U.S. EPA)
It goes on to explain how ozone is harmful: "The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs (see - "Ozone and Your Health" - www.epa.gov/airnow/brochure.html). Relatively low amounts can cause chest pain, coughing, shortness of breath, and, throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. People vary widely in their susceptibility to ozone. Healthy people, as well as those with respiratory difficulty, can experience breathing problems when exposed to ozone. Exercise during exposure to ozone causes a greater amount of ozone to be inhaled, and increases the risk of harmful respiratory effects. Recovery from the harmful effects can occur following short-term exposure to low levels of ozone, but health effects may become more damaging and recovery less certain at higher levels or from longer exposures (US EPA, 1996a, 1996b). Manufacturers and vendors of ozone devices often use misleading terms to describe ozone. Terms such as "energized oxygen" or "pure air" suggest that ozone is a healthy kind of oxygen. Ozone is a toxic gas with vastly different chemical and toxicological properties from oxygen."
It sums things up later when it says, "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."
Also, "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."
"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."
Finally, "If I Follow Manufacturers' Directions, Can I be Harmed?
Results of some controlled studies show that concentrations of ozone considerably higher than these standards are possible even when a user follows the manufacturerís operating instructions."
Scientific studies that lead to these conclusions are included in this document and I would encourage anyone questioning the use of ozone as an air purification device or element of such effect to do the research first, making sure that they understand not only these facts, but the personal facts that only they can get answered by their doctor (sensitivities for example). Advice on posts like these should be taken cautiously and given cautiously as they can be harmful to both the person's health assuming the best (or worst) as well as the weight of responsibility that lies on the advice given with such little information about the individual posting the question.

I should have included the EPA's recommendations for care that are also included in that document: "What Other Methods Can Be Used to Control Indoor Air Pollution?
The three most common approaches to reducing indoor air pollution, in order of effectiveness, are:
Source Control: Eliminate or control the sources of pollution;
Ventilation: Dilute and exhaust pollutants through outdoor air ventilation, and
Air Cleaning: Remove pollutants through proven air cleaning methods.
Of the three, the first approach -- source control -- is the most effective. This involves minimizing the use of products and materials that cause indoor pollution, employing good hygiene practices to minimize biological contaminants (including the control of humidity and moisture, and occasional cleaning and disinfection of wet or moist surfaces), and using good housekeeping practices to control particles.
The second approach -- outdoor air ventilation -- is also effective and commonly employed. Ventilation methods include installing an exhaust fan close to the source of contaminants, increasing outdoor air flows in mechanical ventilation systems, and opening windows, especially when pollutant sources are in use.
The third approach -- air cleaning -- is not generally regarded as sufficient in itself, but is sometimes used to supplement source control and ventilation. Air filters, electronic particle air cleaners and ionizers are often used to remove airborne particles, and gas adsorbing material is sometimes used to remove gaseous contaminants when source control and ventilation are inadequate. "
I wish anyone dealing with these problems and pollutants the absolute best. I would encourage anyone that has a problem to talk to their doctor, and, when applicable, talk to a professional that can help define the condition(s) of the indoor environment in which they live. Professionals can be found easily on the websites of those organizations that oversee education or certification recognition such as Indoor Air Quality Association, Amierican Indoor Air Quality Council, and the American Industrial Hygiene Association. Again, best wishes to all.
Well, #53126, I thought you started to suggest something in your first post when you said: "or HEPA/Carbon filter rather than a mask. There are many that are portable. Masks do not always work well. They restrict air intake and reduce oxygen supply..." Trying to justify the use of an air pollutant like ozone to cover up (or in some cases remove) another air pollutant isn't good advice. First thing I suggest, as I stated in another post, ďI would encourage anyone that has a problem to talk to their doctor, and when applicable, talk to a professional that can help define the condition(s) of the indoor environment in which they liveÖĒ I would also reiterate: ďAdvice on posts like these should be taken cautiously and given cautiously as they can be harmful to both the personís health assuming the best (or worst) as well as the weight of responsibility that lies on the advice given with such little information about the individual posting the question.Ē Iíve heard of lawyers that eat stuff like that up. With that said, since I have not seen the person to diagnose them specifically (Iím not their doctor) nor have I diagnosed their work environment specifically (Iím not working for them as their indoor environmental consultant), I cannot discuss specific case issues; however, I am amply qualified to correct and educate the topic of ozone generators as an air purification process. I believe that that information is helpful when someone is looking into health improving measures in their life so they can know ALL of the facts rather than just a few that may or may not mislead them into a situation that could harm them. I did this the way I did specifically to avoid self-serving measures that might have been considered conflict-of-interest and to provide some good research reporting from an unbiased source for review by those that are looking for ALL of the information so as to make the right decision for them. Again, I wish anyone dealing with these problems and pollutants the absolute best. I hope that whatever works for the better-good of your health and well-being is yourís soon. And, if I have offended anyone in the course of laying out this information and explaining my first post (as I felt I was being asked to do in reply), then I apologize you feel that way. It wasnít my intent to offend you.
