air purifiers

Yeah, I don't like the ones that will just repeatedly cite 'emissions within safe/federal limits' either... not when there are alternative types that will not produce ozone at all.

I looked up the UV systems after you posted and you are absolutely right- they are associated with ozone emissions as are the ionic ones.

There are systems that can be installed in ductwork that use HEPA and charcoal filters, I think. Although they could never make a claim to 'sterilize' the air, many filters of that type are effective to a pretty tiny micron size and can remove a lot from the air.

From some quick reading, it seems UV wave lengths below 200nm or so produce the most ozone, where wavelengths above this produce much less to none. Products that are most effective use both wavelengths above and below 200nm. It seems the shorter ones are actually more effective. I saw you can buy bulbs or devices which filter out the low level wave lengths to reduce the ozone emission, but from my reading I would question the effectiveness. It seems they are basing their claims off research done on full spectrum UV, but saying they are also ozone safe because they block out the short wave lengths. This is just my interpretation from the reading I did from a google search.

Hi All

Posting from Australia. We are in a relatively warm climate and normally have some windows/doors open, even in winter.

Is an air purifier only useful in a enclosed room ?

yes, that is right for it to work properly... and each air purifier covers a different amount of space so you have to make sure you get the right air purifier to cover the amt of square footage you need....otherwise it is recommended to use the purifier in the bedroom where most of the "deep breathing" takes place. <img src="i/expressions/face-icon-small-smile.gif" border="0"> <div class="FTQUOTE"><begin quote><i>Originally posted by: <b>Fran</b></i>
