I run an Ikea air purifier all the time, but still get quite a bit of dust in the computer vents.
Wondering if anyone has had a good experience with a set up to purify the air in a computer room.
Maybe it's just more air purifiers.
There are cheaper DIY options which work nearly as well as bought air filters and there are a few online instructions on how to make one. Basically a box fan with some air con filter taped or attached to the front or back of the fan unit, depending one what sort of fan blade is provided. Some suck better though a filter than push though a filter.
I have in the past relied on the air conditioner unit to clean up really dusty air, but found that I needed a ground level fan blowing over the floor to stir up any dust that might settle. Used this approach for both getting a room ready to paint, as well as back 20 years ago when I needed a clean room to try and recover data off a couple problematic hard drives.
