Hi M N, Thank you for your taking the time to share review about the quality of the Cabin Air Filter. Our products are produced by certified ISO9001:2000 and QS9000 facilities that produce precision OE components. We use the same manufacturers as many famous US brands. Our parts are direct replacement parts, designed to function the same, may not be physically identical to the original, but there are some instances that it even worked better than the OE parts. Nevertheless, we will relay your feedback to our supplier so they can investigate further and improve where it's needed. We have sent you an email. Feel free to reply if you need further assistance. Thank you.
