    I discovered this in high school... we were growing cultures on petri dishes and were given 2 dishes each, we had to open them for 1 minute in a location of our choosing... I exposed 1 in our toilet and 1 in the middle of the cricket oval. The petri dish exposed in the toilet didn't grow a single bloody thing, the one from the oval looked like a terrarium after 2 days. Our teacher told us that because toilets are cleaned regularly with hardcore chemicals not much grows in them. But I've stopped licking the phone after reading the article, and I don't spit-clean my mouse ball anymore.

    I have a small spare bedroom I recently updated as a home office. Part of my renovations were to install pergo-like flooring and basically get rid of any surfaces that can catch dust like carpet and fabrics since my computers seem to get so dirty. It hasn't helped at all.

    One thought that occurred to me was to get an air purifier... one that circulates air with a HEPA filter. Does anyone use one of these in their computer rooms and does it actually make a difference as far as dust goes? They also have ones with UV lightbulbs, maybe this would cut down on the microbe populations? I'm more concerned with the constant accumulation of dust than anything else.

    Really, when you think of your computer area, you don't think of bacteria as you would when you think about a bathroom, so you're less inclined to clean it to the extent you would a bathroom. But either way, pretty much everything else is as equally as bacteria ridden. It's like the test they did on Myth Busters where they tested to see if a tooth brush left by the toilet would really pick up fecal matter, and they found out that tooth brushes all over the building had the same amount of fecal matter on them after a month of use.

    The main concern with the bacteria that live in your colon is that they break down the things that you find indigestible (cellulose, left over protein etc) and produce toxic byproducts. These toxic byproducts are the dangerous things and have to be expelled regularly. They are only safe because once they leave your body, you generally don't eat them up again. The workstation bacteria are probably mostly air bacteria that have found a nice area full of skin flakes and cookie crumbs to breed on. nothing to worry about.

Basically you have an outer room, with all the doors qith at least one other door before the outside, and good seals. All the air is filtered comming in here, not sure how well. There are also stick pads to get dirt off your shoes.

    The inner room, the actual clean room, then just maintains itself through positive air flow. There are a couple layers of filters that take out basically all particles. The bottom of the walls are open so that the air can continually flow out.

    Well this works REALLY well (well enough to work on micro processors in there). There's basically no dust in the outer room, never mind the clean room.

    So if you want to use it in your home, you'll need to make sure that your doors/windows are reasonably well sealed and stay closed. It'll do you no good if a big entrance for dust is open all the time. You also need to keep the air flowing, since some dust WILL get in and it's only getting out via the airflow. Just having it run with your AC probably won't do a ton. You'll probably need continous airflow.
