This is an update of my review I did 10 days ago. I called customer support 10 days ago because my filter stunk really bad after just 2 weeks. Customer service said they would send a replacement filter providing I fill out a review of the product I'm currently not happy with. So I did a review. 10 days later still no replacement filter. When I contacted customer support again they said it hasn't shipped  because I did not provide them with my "nickname" after I completed my review.
