I found a ***** Kenmore Hepa-130 filter at our local "stop and swap." I read on the web that it is supposedly very silent. And when I turn it on, it is indeed silent... ABSOLUTELY silent! I can't remove the top to check the exhaust mechanisms, but does this unit normally use a fan to move air through it? If so, I think my "find" is probably dead.

Thanks!

Sincerely,

Dave
