I have a terrible dust problem in my studio. I have wooden floorboards, the gaps between them are sealed with silicone sealant and I hoover the room and equipment every week. Nevertheless, after a few days the keyboards and other items are covered in dust. I thought about getting an ioniser but have found out that they charge the dust particles and make them drop to the floor which isn't very helpful.

Editor Paul White replies: I think a lot of people have this problem and, as you've discovered, ionisers aren't really up to heavy‑duty cleaning. I think you need to tackle the problem on two fronts. Firstly, remove as much of the source of dust as possible and, secondly, fit an extractor fan with a reticulated foam filter that you can take out and wash. I've also found that dehumidifiers tend to collect quite a lot of dust, so they can be useful in cleaning up your studio air. Also consider fitting filters to the fans on any equipment that doesn't have filters as standard. Any computer shop should be able to help you find something suitable.
Regarding the source of the dust, you've already done the obvious, which is to seal the gaps with silicone. Also check for gaps you may gave missed, perhaps around the edge of the room or under the skirting. Is there any other way for air to get into the room, a ventilation system or grille perhaps? In this case, fit a fine filter there too. Of course a lot of dust is created by people (dead skin cells — yuk!) so you'll still have to clean and, as well as using a vacuum cleaner, an anti‑static fluffy duster will help. It's also a good idea to cover sensitive equipment with a thin cotton sheet when not in use.
