* Beware! *  I had a Conn organ and a piano that had been in an ozone
room, that afterward (six or seven months later) started having strange
problems.  Any organic material used in either the organ or piano had
been "denatured", for lack of a better word.

It caused massive problems.  I am only familiar with this one incident,
which amounted to an expensive repair bill.  These rooms may be safe,
and the company that did this goofed up -- I'm not sure -- but I always
thought "better safe than sorry"
