Yes, they help with dust and mold spores. When I put a new filter in, I get a blast of fresh air from the fan, and when the blast seems to be getting thinner (every three months or so), I take the filter out. Lo and behold, there's all kinds of grime in there! It looks like a vacuum cleaner bag. They really do help.
Which reminds me, I need to get new filters for the ones I have at home. I can barely feel the breeze from my main one.
Wish I could remember how much the small ones cost. I don't want to get you all excited over something too expensive. Go check them out at WalMart. The big ones are very expensive, but there are desktop sizes and small room sizes that might be affordable. I think I may have gotten my small one on sale, but I can't remember for how much.
