Guest guest Posted January 19, 2006 Report Share Posted January 19, 2006 , I just received an advertisement on the airwise purification system. It uses a photocatalytic lamp module, is quiet and appears to be very effective. But, it produces hydroxyl radicals and superoxide ions. I recall you saying in a past post that those aren't good to be breathing. Can you expand on that? What are they and why are they bad?? Anything bad about the photocatalytic lamp? Thanks, jafa --------------------------------- Photos Got holiday prints? See all the ways to get quality prints in your hands ASAP. Quote Link to comment Share on other sites More sharing options...

The Airwise I have just uses heat to sterilize the air that passes through it via convection. Is there some other Airwise unit that generates hydroxyl radicals? I know the one Mercola sells does -- and actually brags of the fact. At any rate, while I don't know what specifically hydroxyl radicals do if inhaled (sounds like a PubMed search is in order) the fact is that they're one of the key causes of oxidative damage in the body. Inhaling clouds of potent free radicals sounds like a very, very bad idea to me, and in fact the very reason that they're effective at " cleaning " and sterilizing air is because they damage and destroy things they come in contact with, like cells. - Quote Link to comment Share on other sites More sharing options...
Guest guest Posted January 21, 2006 Report Share Posted January 21, 2006 Yeah, it sure doesn't make sense does it. You would think that Mercola would be up on this. Is it possible that when inhaled they change to a more benign form? Do you know what superoxide ions are? Some other company is marketing this airwise machine. Can't remember their name right now. Are you pleased with your unit? What is it called? jafa At any rate, while I don't know what specifically hydroxyl radicals do if inhaled (sounds like a PubMed search is in order) the fact is that they're one of the key causes of oxidative damage in the body.

Hydroxyl radicals are major problems in the body, and I know of no mechanism save oxidation itself for them to be altered upon inhalation. Perhaps in some extreme situations breathing in pollutants would be even worse than breathing in a steady supply of hydroxyl radicals -- there'd have to be some research to lay out some guidelines -- but replacing one problem with another isn't an optimal solution by a long shot. And yes, superoxide ions are another kind of extremely potent radical. Actually, the term is generally used to refer to a family of free radicals, not just O2-, such as KO2- and other molecules containing O2-. Cellular respiration actually produces superoxide, which is why we have a powerful network of endogenous antioxidants to compensate. - Quote Link to comment Share on other sites More sharing options...

I have an ULPA filter which is no longer made. Any HEPA or ULPA filter will have some effect; just check reviews on current units to see which is best. They're pretty noisy, though, and they only catch particulates past a certain size. I also have an AirFree sterilizer which just uses mold. That seems useful. - Quote Link to comment Share on other sites More sharing options...
