I am not really surprised how many people think that devices without fans or filters work. Wake up people. It is the same physics that make the ions stick to particles that proves that a volume of air is required to pass thru a filter if you want your air cleaned if at all. All scientific studies show that a filter (glass or carbon) must permit some pollutants to pass through in order to work. The larger the volume of air, the harder to filter, the more displacement needed (the bigger the room, the bigger the fan needed).
If you have a small computer lab that you need to keep clean, a real hepa filter rated for the volume of air in your room will help.
I have a small honeywell filter that was allergist recomended, I also have 4 severs and a workstation always running in my office. They collect dust no matter what. I dust gear once a month.
Stay away from fanless devices. It is like filtering your room with a piece of cardboard (i dont know if anyone remembers the N.S.A. scandel that involved air filters)
I have to agree with all the posts for cleaning and vacuming. That is where you start. Keep the enviornment and the gear clean first. Filter the air second. Clean again third.
