What do people place on their platter for dust protection

"Just a good memory -article from the 1990’s (HP specifically mentioned the "O2" emissions linked to cancer.)."

dweller,

Do you remember if that was really about O2 or maybe about ozone (O3)? Maybe, that is the misunderstanding part. geoffkait’s response was regarding ozone, not O2.

glupson, do you think oxygen is carcinogenic? Wouldn’t that be a kick in the yarbles?

HP was referring to whatever comes out of a negative ion generator. You're right, it may be some other "O"...

Ozone is the short-lived gas molecule O3, whereas oxygen is O2. O3 is an allotrope of oxygen and is produced by ionization of air, not emitted by ion generators. Air obviously is also composed of Nitrogen gas and other gases.

geoffkait,

I doubt oxygen is carcinogenic. It is toxic on some other levels, but that is a different topic (think of Stevie Wonder and similar issues). I just noticed that dweller mentioned O2 while you were responding about O3, including about possible carcinogenic effects of it. That is all. I suspect that dweller’s/Harry Pearson’s point was also O3, but I thought I would ask. It has nothing to do with dust covers, no matter how hard we try to make it all very smart, but once it is discussed why not clarify.
