I damp dust not very frequently, enough so that if people pop around I'm not worried they can see dust lying around.
We do sometimes open the windows to give the place an airing.
My bedroom window lets in a lot of sun and light and I can often see lots and lots of dust motes in the air. I'm an asthmatic so want to keep dust levels down. I'm on here wondering whether it is a normal thing and whether the air everywhere is full of dust, or whether I'm being too lazy on the cleaning (particularly upstairs) and need to be better at it.
Thanks
