Beware returns are paid for by the consumer and are hard to get.
I ordered four filters which were not to the specifications that I had ordered them upon. Once received the measurements did not matched what the package said. When I reported this to Filterbuy to get a refund I was told a label would be sent but I have not seen one since I guess I will have to call back. Also very important they are making me pay for the return shipping on their mistake. I would not recommend buying from this company. Amazon has same quality products for less money.
