Guest guest Posted January 11, 2005 Report Share Posted January 11, 2005 This NanoBreeze product seems to use the same technology as the Sun Pure machines (www.sun-pure.com), sounds great in concept but I can't find any laboratory test results or studies on the machines or the technology itself which makes me question its validity. Any chemist out there who could shed some light on this "photocatalytic" technology ? e Indoor Environmental Testing Inc.www.AIRinspector.com1.800.MY.AIR.TEST product What does everyone think of this? Does anyone know of any recent studies, etc. on the true effectiveness? Home Owners Can Now Use Nanotechnology to Improve Indoor Air Quality http://www.marketwire.com/mw/release_html_b1?release_id=78743 Also, do any of you out there have any good info on synthetic stucco? I have some info, but need to know more. I know there have been many problems with it, but I’m feeling rather lazy and don’t feel like wading through all the muck. I have a client with a rather large synthetic stucco home, and they failed to seal ANY of the windows. There are some weep screed issues as well. Jeesh! Thanks in advance! S.C.

Guest guest Posted January 12, 2005 Report Share Posted January 12, 2005 Sounds interesting, recently I had noted a florescent bulb with the same coating in the Buildings trade magazine.

Guest guest Posted January 12, 2005 Report Share Posted January 12, 2005 I did find one article with regard to surface disinfection in laboratories. Kuhn et al. (2003). Disinfection of surfaces by photocatalytic oxidation with titanium dioxide and UVA light. Chemosphere 53: 71-77. (pdf attached) To me, the chemistry sounds right but I wonder, is free radical generation any better than ozone? And if air is not being drawn into the device, then it seems kind of pointless. Anyone have any informed opinions on this gadget?

Guest guest Posted January 12, 2005 Report Share Posted January 12, 2005 We use large commercial "UV Air Decontamination units" in our restoration business from http://www.solair.ca/ We've been testing several of them for over a year. They appear to work quite well on smoke damage, and we use them in conjunction with HEPA filtration on Category 3 Black Water Losses. The propaganda from the company says that they are "proven effective in the removal of VOCs, allergens, pathogens, and bacteria in various situations including school, hospital, and restaurant applications." I'm not sure if that's the case. They claim to also be effective against mold, but the IICRC S520 specifically states that they are not recommended for remediation because they do not physically remove the spores. I would like thoughts or comments on the technology. In practice, they appear to work, but I'd like to know if it's technically sound. From their site: UV Clean Air TechnologySol-Air Systems’ patented technologies disinfect the air by employing multi-frequency ultraviolet light killing bacteria and other micro-organisms at their molecular level. Sol-Air’s systems deodorize air through photo-oxidation and the production of quick acting yet mild oxidants (hydroxyl radicals), which break down and neutralize volatile organic compounds.The UV Oxidation ProcessClick here for a list of the common odors and contaminants eliminated by the Sol-Air decontamination system.

Guest guest Posted January 12, 2005 Report Share Posted January 12, 2005 I find it interesting that nowhere on the product website are any indications that this device has been tested to show that it actually does what they say it does. Personally, I dislike portable air cleaners in general, but I am highly suspicious of any firm that litters their advertising with impressive sounding factoids that are never empirically tied to their products performance. BTW, this device must be truly miraculous if all " pollutants " are transformed into water and carbon dioxide, especially in the case of chlorinated solvents. Sounds like crap to me.

Guest guest Posted January 12, 2005 Report Share Posted January 12, 2005 Did anyone notice the company's example of how hydrocarbons are "broken down" by UV catalytic oxidation? See below (hopefully, it's still there). Methane (no PEL - simple asphyxiant) is converted to methanol (200 ppm TWA) is converted to formaldehyde (0.75 ppm TWA) is converted to formic acid (5 ppm TWA). Is this really improving IAQ? I understand that acids and bases can be neutralized, but what does it mean when VOCs are neutralized? That's a marketing term, not a scientific one. Whatever good the machine might do, there is sure to be a better approach to achieving that same end. Steve Temes I would like thoughts or comments on the technology.

Guest guest Posted January 12, 2005 Report Share Posted January 12, 2005 I agree with you Dean. If a company had ANY empirical evidence whatsoever that their product worked, you would think this data would be on their website SOMEWHERE, if nothing else available as a link or something. Another interesting note is that I asked the 2 companies who advertise this technology to send me some scientific data and I yet have to get a response. Speaks for itself. If they should respond and provide anything of value, I'll be sure to share it with the group. e Indoor Environmental Testing Inc.
