Hello Robl. This is a strange occurrence, as the washed filter should not have this kind of affect on the performance. We are interested to learn more about the change in performance specifically and to work on a resolution. At your next opportunity, please join us on live chat on our website or call us at 800-374-4432 M-F, 8:30 am-8:00 pm EST so we can start this process. Kindly, Anna
