Dust in the studio .....

But the dust is from you anyway... You need to wear a full suit and mask...

I usually keep my windows shut and use a good air filter for my A/C which helps some. Part of the problem seems to be that electronics equipment can harbor opposite charges which in turn, attracts dust charged the other way. Wiping things down with an anti-static cloth can help. Nothing will completely eliminate it since there will always be some small particulate floating around in the air...unless you set up in a clean room.
 
One suggestion concerning your DAW......place a small filter over the air intake. Might not look attractive but it helps. 

Wonderful suggestions Jerry! 
 
I once worked in an electroinics repair shop where we regularly took equipment outside and gave it a good cleaning with compressed air.
I have seen electronic equipment work great covered with dust. Dust in and of itself is fairly neutral as a conductor. Dust is basically very fine dirt with possibly some pollen mixed in...at least in the spring when pollens are especially bad. There is the very slight possiblity there could be some kind of  microscopic conductive minerals too like aluminum. I would say this is very slight though because to be light enough to float only the lighter things are airborne. Even though dust is neutral as a conductor it can be charged and this charge is what attracts it to electronics equipment. 
 
Several things need to happen to seriously affect equipment. The dust must somehow become conductive AND bridge across a connection to cause a short circuit. One of my computers has been running for 5 years and has a nice little bit of dust in it but still not enough to cause any major concern. I guess you can tell I don't get too upset about a little dust :)
 
The last time I seriously cleaned a computer I did everything I knew to do. I discharged static. I made sure everything was grounded properly. I discharged static. I used powerful and moisture free compressed air from an air compressor OUTSIDE  ( so I wasn't blowing the dust around in my space to simply settle again).
 
I felt quite proud of myself with a nice clean computer. I plugged it all back in and my firewire didn't work..to this day I don't know what killed the firewire board...so now I really hesitate to touch my partially dusty computer. It ended up costing me a new firewire card.

I like my mixes hot ... but not that hot!

Crazy dust here in NYC. Despite having an $800 air cleaner with 3 stages of filtration, I still fight a constant battle with it. I wonder if much of it is still 9/11 dust. Anyway it's definitely about time I vacuumed my DAW.

Dust... the bane of modern electronics.
 
No matter how clean you keep your studio space, dust is inevitable. 
 
Check the air input filter from time to time. When you see it starting to turn gray, it's time to clean the machine.
 
Open it if it's a desktop.  I use the air in a can which is moisture free. I also use a clean, dry paint brush to get into and between the cooling fins and down on the circuit boards. It's amazing how much dust can get on the boards as well as in the cooling fins. All of it needs to go.  
 
Blow it off first, brush it next, blow it off again.....
 
Blow it out. Brush it out.... just get it gone. The processors create a lot of heat and those fins need to be clean.
 
I went to a service call for a company I do some subcontracting for. It was in a hospital maternity ward's security monitoring system. You would think, that of all places, that a hospital maternity care ward would be a clean environment. You'd be wrong.  The servers were crashing after they were on for an hour. I looked at the input ports for the server cooling air and it looked like they had cotton stuffed in them.  Some canned air blown on the port resulted in dust bunnies in the air.  I opened the servers and the processor heat sinks were a mess. There were dust bunnies all over that desk when I finished. but the fins were clear. Needless to say, the head of maint/security didn't want to hear that the only problem was a lack of preventative maintenance in cleaning the dust or that the crashing they experienced was that simple to fix. I have run into this very same issue in several other hospitals as well. BTW: the first one I mentioned...the servers were only 9 months on the job and in that time were totally clogged. I suggested to the maint staff that they schedule a dust cleaning on the system every 3 months to prevent this issue in the future.
 
The ones I love are the ones where I'm there for something else, and I look at the server and the USB port on the front has a dust streamer and fuzz around it where the dust exiting the box has built up. If it's on the USB port, you can rest assured the inside is wrapped up with it. I'll usually blow it off with canned air and inform the staff to clean it more fully.....which I'm 99.9% sure will never happen..... In the words of Arnold.... "I'll be back"
 
At home, in the studio and house, I check and clean my studio electronics periodically to keep things running cool and smoothly.
