I have a room with west facing windows (I dont think the direction bears any importance to this question), but for some reason this room seems to accumulate dust on surfaces a lot faster than other rooms in the house. We try and spring clean the house every year, but within about 6 months, the surfaces (my desk, computer monitors/keyboard, wardrobe, en-suite bathroom worktop, wardrobe shelves, drawer surface and pretty much every other surface on that side of the house) seems to accumulate a large amount of dust. After just a few weeks, you can see the dust build up on some surfaces and write on the surfaces with your fingers. To keep the place neat requires a wipedown with a wet wipe, every weekend at the very least.
This is the kind of grey fabric texture dust that seems to spread with time in homes and offices (not sand dust or atmospheric dust - that you would find in building sites or while plastering a wall). This one room in particular seems to be more susceptible to dust than all the others in the house. Even though we have our doors and windows open an equal amount in other places. The whole house is carpeted - the fibres of which, I believe is a major source of the dust.
We do have a working fan in the en-suite bathroom, which reduces steam buildup after a hot shower, but I do not think this is a source of the dust. But perhaps helps to blow the dust around a bit.
In any case, what are some of the better solutions for reducing/removing dust from the air, and thus stopping it from settling on surfaces.
