Hopefully, ARoberts will come in here and field your question.
In general, asthmatics seem to have trouble with Ozone cleaners. Do a search for past posts on this newsgroup. And also at WebMd asthma board there are many posts by unhappy consumers of the Ionic products and Dr Enright had posted the research into this area several years ago. I think I read somewhere there is a lawsuit by the Feds regarding advertising by companies who claim their air cleaners will help asthma so see if you can come up with the details.

Someone gave me one and i gave it back. Didn't do a thing for the real trouble makers at our house. The hepa filters make a big difference if you get a good one and maintain it properly.

I would love to include the experience of someone who [quoted text clipped - 4 lines] > Joe Mullich > www.joemullich.com I know that Sharper Image (marketer of Ionic Breeze) spend lots of advertising dollars in inflight magazines, so this probably isn't welcome news. Ionic Breeze and other ozone-producing air cleaners are not recommended for anyone with a respiratory condition. Ozone (O3) is extremely reactive with airway epithelium and can cause permanent injury. The EPA and various health organizations have warned against using such devices, saying that ozone, in the concentrations needed to effectively clean indoor air, is unsafe for humans and animals. The FDA has brought actions against various manufacturers for specious claims of the benefits of ozone-producing air cleaners.
A HEPA filter is far superior, both in effectiveness and safety.
From the EPA website:
"Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections."
"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."
"Whether in its pure form or mixed with other chemicals, ozone can be harmful to health."
" When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and, throat irritation. It may also worsen chronic respiratory diseases such as asthma as well as compromise the ability of the body to fight respiratory infections."
"Some studies show that ozone concentrations produced by ozone generators can exceed health standards even when one follows manufacturer's instructions."
"Many factors affect ozone concentrations including the amount of ozone produced by the machine(s), the size of the indoor space, the amount of material in the room with which ozone reacts, the outdoor ozone concentration, and the amount of ventilation. These factors make it difficult to control the ozone concentration in all circumstances."
"Available scientific evidence shows that, at concentrations that do not exceed public health standards, ozone is generally ineffective in controlling indoor air pollution."
"The concentration of ozone would have to greatly exceed health standards to be effective in removing most indoor air contaminants. In the process of reacting with chemicals indoors, ozone can produce other chemicals that themselves can be irritating and corrosive."
Cara - 30 Jun 2004 23:17 GMT Hello Joe,
My son has severe asthma. I've been through the Sun Pure, Bionaire and one other filter whose name I forget. None of them seemed to be helping my son's nighttime coughing and itching. I turned them off to see if that made him wose but there was no difference.
Then I found the AirSource 3000 from Shaklee. I did a 7 day trial and within a few days my son's itching was gone, his breathing was improving overnight instead of getting worse and my husband stopped snoring. I was thrilled. The difference is in the AirSource's ability to remove bacteria and mold spores from the air - these are too small for the HEPA filters. The Sun Pure was supposed to kill bacteria but now I understand that the UV light inside the filter primariliy keeps the filter itself from being a breeding ground for bacteria and mold.
So, that's my vote for air purifiers.
Will you post your article here after you've written it?

I would love to include the experience of someone who [quoted text clipped - 4 lines] > Joe Mullich > www.joemullich.com I was looking through the July issue of my son's Mad magazine last night, and there's an "ad" for The Ironic Breeze Silent Air Purifier from The Shoddier Image.
It's a pretty funny parody; for example there's a chart of "Air-cleaning ability when compared to other brands". The other brands are; Salton Toaster Oven, Kodak Digital Camera, Black & Decker Snake Light, and a 1991 Buick LeSabre.
There's an explanation of how it works, (and how it sucks money out of your credit card); how the full five-year warranty covers all the packing materials, instruction book and the rubber band that holds the AC cord wrapped up in shipping; there's a testimonial from a "customer", and a bunch of other pretty funny stuff.
Maybe someone from Mad magazine got burned buying one of these useless pieces of crap and decided to have some fun with it. Seems the writer shares the same opinion of this wretched chunk of crapola as a lot of folks with asthma and allergies do.
It's worth a look if you happen to be browsing a newsstand.

merlin - 10 Jul 2004 05:11 GMT > > Hi. I am writing an article for an inflight magazine about indoor air > filters [quoted text clipped - 31 lines] > > Garth Allen. Dear Joe, Quite obviously the material you are actually seeking and of most general interest for the kind of article you describe is a little outside the scope of your apparent question of simple air filtering idelogy. What is actually in question is what the actual combined makeup of the air within a general home or workplace actually is, how it actually affects various people within and what they might decide or are able to do about it. Much is mentioned about ozone and it's adverse effect on people, which of course is a fair statement, but this is somewhat stressed to the point of absurdity with common claims that ionisation systems generally are ozone producing and therefore dangerous, so much so, that the entire concept is completely mistakenly misrepresented. You mention that you are interested in aviation as your target, which co-incidentally happens to be a most interesting application of this particular technology, most especially ionisation technology and ozone avoidance. There is much that needs to be mentioned so that any non-technical person might better grasp some of the basics of this technology, I will mention the ionisation tool ideology to begin with. . The entire technique is very simple, any physically tapering object with conductive surface properties that has an Electo Motive Force (EMF) applied, has an inherent propensity to emit an ionic flow from it's apex, this is simply explained by the EMF exciting surface electron activity which has a "bumping off" effect at the conductor tip. If the EMF is increased the effect is increased, so that an "ionic wind" is created off the end of the tapered section. If the applied EMF is positive, ozone is produced, if it is negative, a negative ion stream is essentially produced. There are enormous potential applications for this effect. If we consider an aircraft wing, we have a perfect tapering conductive device, and of course the sharpest point is the rear-most outer extremity, and it just so happens that if an EMF is applied to this structure such as created by flying through a charged cloud, then discharge will occur at this point. In the case of a higher EMF such as might be experienced from a lightning strike, once again the concept holds, and the discharge is most generally from this area, sometimes even causing damage. In that general uncontrolled static discharge (EMF) is prone to causing radio and navigation equipment interference, we place devices in the outer trailing wing areas (and the tail similar sections) to progressively allow discharge in a controlled way, which overcomes the radio spectrum noise generation problem, these are of course called static discharge devices. (Probes or wicks) With slower velocity aircraft the term "wick" was used because a graphite impregnated chord was used similar to a lamp wick. As the velocity of the aircraft increases, the inherent problem of static generation also increases, so a better technique of removal is required. Nowdays a resistive plastic piece of material some six inches or so long with a sharpened tungsten needle at it's extremity, or a newer combination of special steel wool, multi point material on a length of resistive carbon fibre is used. The operating principal remains, a tapering conductive device will allow an EMF to be disipated into the surrounding atmosphere, which is highly desirable especially with aircraft generally. These devices are a simple extension of the physics involved allowing progressive controlled discharge. One further item that requires mention is the ozone generated from lightning. Everyone would be aware that ozone is virtually positively charged oxygen, magic stuff, it allows life to exist but also has a downside if you suck it. As we increase altitude above sea level, we pass through various layers until we reach the ozone layer especially over the equatorial areas, which of course is maintianed in place around our planet by PFM, (pure magic) we seem to be entering a situation where for one reason or another some people are becoming alarmed to find it is depleting. If we accept that this layer has a somewhat positive charge and then as we gradually descend back into our atmosphere, we eventually come to clouds, oddly enough the tops of clouds also carry a substantial positive charge, and the bases are of course substantially negative. These charges alter in relation to the cloud content and activity but the polarity orientation remains the same. So we have a situation where from time to time, the inherent charge is sufficient to generate a path and discharges to the earth below, real magic stuff, but what commonly happens is that a different kind of lightning also discharges vertically above the clouds toward the ether, and of couse we have ozone occurring at different levels in differing degrees and concentrations. As we fly higher in various aircraft, ozone begins to have apparent effect in cabin recirculated air, the pressurisation which is sourced from engine compressed air, the interesting thing here is that some people are more susceptable to these kinds of effects than others. Some have greater sensitivity to irritants, I wonder which group this might be? Some higher altitude aircraft actually have ozone filtering in their air conditioning systems. Now to mention a little about lightning below the clouds, most especially direct cloud to ground strikes. It is often mentioned that people are affected by ozone after an electric storm, but what needs to be understood is that lightning is essentially two parts, the enormous EMF from the cloud which is incredibly negative and a second part which emanates from the ground which is a positive EMF, these two elements meet somewhere in a thirty feet or so height envelope above the ground and anyone nearby that has actually witnessed a close encounter of this kind will bear testimony to the pungent strong ozone that is generated mainly from the positive EMF involved from the ground element, of course this effect is near the ground and quickly dissipates as the circulating air neutralises the effect with the other ionised air from above. So this confirms why the air is so clean, clear and breathable after an electrical storm has passed and also why some people may have a whiff of ozone at that particular time. The reduction in the atmospheric inherent positive charge naturally affects the ability of the air to support foreign material, thus considerable fallout occurs, especially affecting pollutive elements. In some cases it might be possible to find increased pollutive effect at ground level immediately after such an event or that the íncluded precipitation may carry pollutant material to earth. The overall picture is neutralised charge atmosphere and cleaner air generally. Another most interesting apect is that a negative EMF has the ability to arc considerably more distance than a positive EMF. This is why all ignition systems using an arc or electrically generated spark are always negative. A further interesting phenomenon is that a spark from a positive source and a spark from a negative source have entirely different properties. A positive high voltage spark is a blue simple zap, whilst a negative sourced spark is a blue simple zap with an extra element of yellowish fire surrounding it plus the ability for a similar negative EMF pressure to jump a significantly greater distance. This was commonly a problem in the days where vehicles with six volt ignition systems were difficult to start, the coil connections were often reversed which resulted in a positive spark rather than a proper negative one, plenty of cranking but no firing. Lightning is a simple further demonstration where a negative spark has incredibly greater abilities. By long term problem observation it was obvious that a device constructed to apply the intelligence of ionisation could be incredibly useful, especially in the case of airborne substance problems in homes etc., which were affecting the inhabitants, most especially asthmatics or those with airborne substance sensitivity problems. In the late seventies I began to experiment by constructing various devices using various ideas to produce a negative ionisation stream with a view to neautralising in home atmospheres which are always positive, through inhome appliance use and various lamps etc. As mentioned the theory is simple, a high EMF generator simply coupled to some tapering conductors. I did try various stepup transformer ideas to produce various EMF pressures, many of you would be aware of sitting down with reels of enamelled wire and working on textbook formulae to produce these devices using ferrite housings etc., this idea proved partly successful, but after half a dozen operational devices was deemed impracticable. I altered the idea by using a direct mains operated voltage multiplying ladder circuit, and the idea really began to show incredible promise, I was using old gramophone needles and sections of high quality sewing type needles soldered to a circuit board as the transmitters, the best effect appeared to be using a developed negative EMF of between two and two point five kilovolts, with some eight or so pointed needles. These things are certainly interesting to play with, if placed over a white sheet of paper, a fallout pattern appears after even a couple of days and after a month or so the effect is extremely evident. Breathing the air in front also appears to taste better, well worthwhile trying. The area at the tips of the transmitter elements show small blue points of light emanations and the ionic wind generated is really interesting, almost as strong a a person lightly blowing in a concentrated area. A solid state fan more or less. So the best prototype was replicated half a dozen times and placed into a suitable casing and the items distributed to persons with problems, to place in their bedrooms with a request for reporting any effect. Everyone reported a different sensation of apparent improved air quality in their bedrooms, but after some eight months the effect reduced substantially. The ionisers were retrieved and carefully inspected, one had a power supply fault, the others all had substantially reduced ion output, the needles were all heavily eroded at the points and when replaced, restored excellent operation. In view of the short-lifed point effect and the fact that we have very little pollution effect at this particular global location, the entire idea was scrapped. In summary the effect would be extremely useful if I could have overcome the point erosion problem and if there were a need at a location for these kinds of devices, but they would need regular operational inspection and possible parts replacement. With regard to ozone, the units I was testing showed no sign whatsoever, care was taken with the power supply arrangement and mounting setup, the stepup transformer devices would appear most likely to generate ozone from collected attracted fallout and the mains voltage multiplying circuit appeared much more reliable and efficient. I was however most interested in the ozone effect mentioned, as everyone would be aware, halogen lamps produce quantities of ozone, so by making a string of halogen lamps in a glass tube and passing air through the tube, a simple concentration of ozone can be obtained. Everyone would be aware of the effect of breathing ozone, very similar to breathing a dilute chlorine mixture, and the effect is also similar, dry sore throat, watery eyes, best described as an irritant kind of reaction. It did appear to me that asthmatics were most likely to be affected more severely than normal people, which I suspected might be due to increased mucus possibly absorbing the gas similar to chlorine dissolving in water kind of effect. A device was constructed to enable the ozone to be syphoned by venturi effect into a swimming pool pump water return This idea began to show sterilising promise but was inadvertantly terminated when a person in the pool blocked the return line which flooded the device causing its immediate self destruction. The lesson learned here was that ozone has most interesting properties and has potential application in other technical areas, also that some kids do the darndest things. The idea had been basically aimed at observing effects of ozone on water quality, sterility and people with that water. A further interesting development occurred when I was repairing a reverse osmosis desalination unit, it also contained an ultraviolet water steriliser unit which was essentially a large mecury vapour lamp suitably located inside a water circulation arrangement, I suspected that generated ozone may also have been a factor in it's operational effectiveness. I have mentioned a bit about various kinds of ionisation, how they can be generated and some apparent qualities, now I will mention some further observations. An asthmatic (allergic) adult person, three year history, moderate to severe problem, situation analysis identified problem pets, aromatic substances and general dust. This person applied every effort to overcome their problem which was confirmed as obviously airborne sourced, most especially in their home. A standard Murphy remedial method was adopted, but this person also procured three air filters and after arrangement in her home reported that the asthmatic problem had lifted virtually entirely by the next day, incredible stuff !! I was expecting situation improvement, but this person had shown incredible improvement within two days. She was astonished as was I. I enquired as to what kind of air filters had been used and how they had been positioned. I was informed with a model and brand name. I envisaged a micronic filter with activated charcoal element and was amazed to find the filters procured were actually ionisers, with no filtering capacity that I could actually determine, apart from the fall-out effect from a neutralising atmospheric charge. The particular units in this case were "Sharper Image" which as far as I can determine were simple ionisers, but I really would like to get one and see "what makes them tick" I suspect it would be a simple device, much as I previously mentioned, but my interest would be in the housing, the voltage source, amplitude and the transmitter head design and what material they have used, really to see if they have overcome the erosion problem. It certainly aroused my interest. This is just one of many problems solved using air filtering or altering devices, this just happened to be the most remarkable in my experience, and was coupled with other problem avoidance practical remedial ideas. One other air quality improving idea involves anyone with room airconditioning, most especially stand alone wall or window units, these usually have a removeable front panel which enables access to the filter element. This is usually a flat fibrous element similar to a "scotch-brite" scouring pad but larger in size. Over time this element gradually collects dust. This effect can be significantly enhanced by simply removing, cleaning and refitting it, then carefully placing a single layer of "kleenex" tissues as to cover the entire exposed filtering area, this might sound rather simple but the air filtering quality of the machine is enhanced and actually becomes better still after a week or so, the tissue material will need to be replaced periodically, but it becomes a simple task and really collects a lot of airborne rubbish. Other filters involve paper elements, ozone cells, activated charcoal, negative ion systems, and even a scrubber system. So what type of unit might be most useful? If we analyse the situation quickly, such as a recent experience I had, I entered a small building for a moderate corporate office area, all ceiling lighting was hidden, the company motif on the wall was illuminated from lighting above, behind and within. The entire area was carpetted with high cut pile type plush carpet, numerous TV and CRT type monitors were present with all kinds of information displayed, the airconditioning system was a typical recirculation unit mounted in the ceiling/roof involving two units. The girl behind the reception desk had a reddened nose typical of someone using tissues. In this case without even doing any testing we had all the elements present, there must have been at least fifty halogen lamps operating, TV and Monitors would have also been generating ozone effects, so collectively it would indicate that there would logically have to be a considerable ozone element present in that mini atmosphere, the high plush cut pile carpet would obviously enhance this situation by accellerating static generation by anyone moving around that area, especially if they were wearing synthetic substance clothing. Several laser photocopiers were also observed. This is part of the reason that modern airconditioning systems regularly include negative ionisation systems, this situation did not have any minimisation device whatsoever. There are only three ways that I know to overcome this problem, one, use an activated charcoal inline air filter, two, use a suitable negative air ioniser system, and three, replace the entire air volume frequently. The problem can be further reduced by using loop-pile carpet, this sounds odd, but remember point-emission, the present carpet would likely be treated with antistatic chemical and the material is not fur, so we could expect a further positive emission from that source generally. I suspect it was one of those offices where everyone gets a static shock as a daily expectation and sickness rates would likely be high due to suspended breathed vapours from sneezes and such. I have mentioned a couple of device concepts in reasonable depth here because I do repeatedly observe flippant remarks being made in respect to these ideas without consideration of the implications or benefits, this will also allow you to better grasp the material you need to understand for your project and some idea of the questions you might need to ask the manufacturers of these various devices. Anyone feeling dry sore throat kinds of problems from any office environment might better understand the possible causes and any office furnishing company might consider some alternative ideas. An excellent place to observe lightning in my experience was Nadi, Fiji. This is a tropical paradise and in the wet season the cloudbase comes as low as six hundred feet, heavily leaden, and develops through the hot days so that in early afternoon any disturbance such as a landing aircraft disrupting the inherent charges, begins the show. This lightning is simple vertical ground strikes, as frequent as five seconds or so, over a localised area. The strikes can be as close as fifty feet or so from you, and people are often struck, but it remains a lightning watchers paradise. The best observation point is from an all metal small vehicle parked in the vicinity of the Nadi golf club near the water's edge. The local airport had isotopic ionisers placed on top of fifty foot poles designed to reduce strike effect in that area. (Lightning deterrent) Brisbane Australia, (semi tropical) also has a most excellent frequent natural summer electrical storm display, this has even warranted a television text page with a real time lightning activity map. These strikes are again vertical zaps, occurring at about ten to fifteen second intervals, again a delightful display of nature but not quite as predictable as Nadi. This warrants a ritual procedure of unplugging aerials, switching off all sensitive electrical devices and not using telephones during the passing of these storms. The cloud base of these storms is average 900 feet, and they pass in thirty minutes or so. It most certainly has an incredible improvement effect on the atmospheric air quality even though there is very little pollution here. Probably the most unsafe area that you can possibly be during lightning activity is on a golf course green, the constant watering and fertiliser increasing ground conductivity in these areas makes them a lightning magnet, the safest place is probably a small all metal sedan type of car or a metal shed. Remember I have mentioned this, as you will experience a closeby lightning death in your lifetime, just ensure it is not yourself. Ionisation is an incredible area for discussion and experimentation, it is a natural phenomenon, delightfully simple, but much mis-understood. It is an incredible tool for assisting air quality especially in large volumes of airflow, remember that airborne bacterea is also affected and reduced. Using it's effect sensibly is incredibly beneficial. Even the modern electronic camera flash produces an effect capable of igniting a fuel/air vapour mix involving an associated effect. With regard to an asthmatic person affected by airborne substances remember an ordinary paper filter will not remove ozone, an activated charcoal filter will, an ion generator has a much greater effect and will also do the job very well. All devices have negative considerations, paper filters clog and need regular replacement, charcoal filters also have limitations and need periodic replacement, ionisers probably need periodic transmitter head replacement. So you see there is a little more involved than would appear evident. Thankyou. Merlin. .

It's like watching a horrific accident unfold--one is compelled by the sheer disbelief of it all. Have you noticed that those who threaten to leave and never come back because the world is not ready for their "knowledge", always return? Self-aggrandizement is a most powerful motivator.
