Landshark75,
Thank you for this valuable information. I'll definitely check it out. BTW, we have the Sharper Image air cleaner and do not like it. It actually spreads an unpleasant tinny odor and is not noiseless. I always wondered what the brouhaha was all about.
Vvrinc,
I'm one one of those anomalies, a husband whose wife is also his best friend. I know there aren't many of us who can say that, so I won't hold your comment against you.
:)
