How do I keep my dedicated room & gear cleaner?

Get the largest HEPA type room filtration machine you can afford. Check the threads there was one a week ago.

Try Endust cleaner for electronics. It puts a charge on the chassis to repel dust so that it lands somewhere else.

Move. Just kidding;>)

Cool. Good idea. How LARGE might you be talking about? Could something like what you've suggested be moved easily enough? Wouldn't want some big industrial sized monster populating a lot of floor space in my beautiful dedicated listening room,(the room is a showpiece in itself),and must have high wife acceptance factor. I WILL check into the Honeywell Hepa for sure.
What about an OREK? Saw one of those late night "infomercials" and the OREK ProShield Plus air purifier looked like it might be a player. Anybody own one? If so, does it work well/do the job? T.V.ad claims that it cleans and recirculates all the air in an entire room 10 times in 1 hour. I guess that sounds like a good thing? It runs about $400 and is supposed to operate very quiet. Looks pretty stylish too. Input from owners of it is appreciated.
