This damn filter is a complete scam. It doesn't even fit the Dyson DC14. It's too big and compared to a filter made and bought by Dyson it doesn't even come close to matching the quality of the materials. I sent one back and originally ordered two to have a spare. But I have to pay the return shipping and they are more than the cost of the second filter so I'm stuck. Be careful when shopping with these foreign companies. I really think they will make a cheaper sale and then like me you are stuck on a product. Why can't people (i.e. companies) just be honest and sell a good product at a fair price?
