    DEMCI filters are so fine that I can actually see dust collect on them in as little as 48hrs. A visible circle, the size of the fan (or in my case, 3 140mm circles on a 3x140mm magnetic filter). All it takes to clean them is to literally just wipe your hand across them, it just rolls off easily. My house is clean, though sometimes a little untidy. Its amazing how much dust is in the air in even the cleanest environments.

    Hepa filters are completely unnecessary, but basic fine mesh filters are a must if you don't want to do the whole air compressor/brush declogging process every year. A clean computer, particularly clean fans and fan cooled heat sinks, runs a lot cooler. It astonishes me how some old machines I've fixed up for customers have even still been running, with dust turning heatsinks into solid blocks of dust and detritus.

    I made a couple of little stands to keep the pc's off the floor - makes a big difference to the amount of dust they suck up.

    This is so true. You can't even see any heatsink at all.

    Here's a before and after of the inside front of a case
