The Dyson filters do tend to block after years, or mine did anyway, was told lifetime, but at 5 years air flow was down, new filters all good again. Its my only Dyson, I do like it, its easy to use and works, for ME. I Got a good deal on it at $181 clearance, nothing has broken at all, still looks and works like new 6 years later.Not built like my 82 Silverado I would say, but what is?
