When Bill Morris from I Heart Robotics decided he wanted a cleanroom, he did what any self-respecting maker would do -- he built one from scratch. I asked him what you could use it for and he said:
...it would definitely make opening hard drives much safer. It could also be really useful for the diybio crowd. I need to use if for opening up laser scanners and cameras and avoid
contaminating the optics. I am also planning on using it for applying touch screen protectors without getting motes of dust caught between them and the screen.
First, he put together a budget lab bench/enclosure from heavy-duty MDF shelving.
Next, he 3D printed some end caps to couple a dust filter to a PC cooling fan (you can download the files here).
He was using his noggin when he thought to install some good lighting in there; nothing's worse than squinting over your bench trying to see what you're doing. Finally, he used a shower curtain to close off the front (a temporary solution until he gets something a bit easier to look through).
I used a clear plastic shower curtain to test things, but the shrink film for window insulation might work even better since it will be almost completely transparent. In this design you just reach under the curtain to perform science or extreme disassembly. Blue painters tape seems like a good choice for temporarily sealing large gaps. Remember the clean room does not need to be air tight, it needs to have a positive pressure. So wherever there is a gap the air should be flowing out. If anyone knows any easy ways to test the quality of cleanroom please let me know. So, now that the cleanroom workspace has been built, I wonder what it will be used for?
This would be great for applying finishes to small woodworking projects; I have a heck of a time keeping dust off.

To test your tidy room, it'd be good to buy a "cheap" particle counter.

The class of a cleanroom is traditionally classified by the number and size of particles in a given volume of air.
a class 1000 clean room, for example, has around 1000 particles that are >=0.5 microns per cubic foot of air.

You'll get better airflow with a squirrel cage blower - a traditional fan doesn't overcome the resistance of the filter very well. Here's some examples: http://www.surplussales.com/Fans-Blowers/FansBlow-1.html
Impressive build though, I wouldn't have even considered doing this, but now I'm contemplating a box of my own.

Here is a video tour of the cleanroom which should give a better idea as to how it is put together and how the airflow works out.
