Dusting gear and turntable

How's about getting an air purifier near the equipment rack. 

FWIW:  I HATE dusting!  It's a thankless job!  However, when necessary, I use a vacuum cleaner with a HEPA filter.  Since the late 70s, however, I've been in the habit of using dust covers to entirely cover my TT, amp and CD transport when not in use.  I had some old computer & office equipment dust covers that work perfectly for this.  Aesthetics be damned!  When the music is playing and the dust covers are off, of course, everything looks pretty.  When not, well, dust is the enemy of any electronic equipment, and I don't give a damn about the aesthetics.  When removing the dust covers, of course, even though there isn't much dust on them to speak of, I walk them gently to another room or the porch and shake them out.  I'm surprised some clever audiophile marketer hasn't already devised a way to manufacture custom dust covers for this and sell them for the usual exorbitant audiophile equipment prices ... or have they?

Stereo Squares (stereosquares.com) will make acrylic dust covers to standard sizes and/or to spec. They do very nice work.

Oh boy! Another thread on dust covers seems to be emerging.  I can't wait.

If you keep your room appropiately clean, a dust cover isn't at all necessary IMO. If you don't keep it clean enough - why not?

I could see a big heavy dust cover being maybe appropriate if you have a cat, but then you better hope they stay away from your speakers too (some love to claw at drivers). It could also be advisable if you had a linear tracker arm with a mile of precision bearing surface to collect dust and get gummed up over time (e.g. ET 2).
