I have had a Dyson DC28 since 2010. It was working great until I first decided to buy new filters. After each use, the "pre-filter" clogs and the vacuum cleaner loses suction power. I've never seen anything get into my original filter, but on this one I see tons of hair and dust. I have to shake it out and wash it every time. I have a cat, a dog and three kids so I usually vacuum every other day and I can't do that if I have to wait for this filter to dry. I cannot recommend this filter. Next time I'll buy a brand.
