It's getting to that time of year again when my house becomes unbearably warm upstairs, so... as per title. The problem with 'regular' fans is that it gets to a point where you're just moving warm sticky air around... While I have no doubt that the Dyson 'cooling' or 'hot and cold' fans are really good, I have absolutely no desire to give any money to that tosspot. I'd even consider an air conditioner, if you can recommend one that: a) doesn't cost the earth (i.e. up to £300), b) doesn't sound like an industrial estate when in operation, and c) isn't just an evaporative water cooler being sold as an 'air conditioner'.
