Dusting gear and turntable

Try the California (original)car dash duster for automobiles. It’s red and oval shaped. It’s what I use and it’s great. Around $12.

I don't really have much issues with dust. My wife vacuums on a regular basis (2-3 times/week), and even checks that I have the stylus guards fitted to both tonearms before she goes into the listening room with it vacuum. I have a feather duster for the turntable and gear. That works great.  

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.
