After two years of 7x24 use and periodic cleaning, it took only one dishwasher cycle to ruin the original filter which emitted horrible odors and while fully dried made clicking/ticking noises. Our call to support concluded with the recommendation to replace the catalytic carbon filter which took 3 weeks for delivery. That did not resolve the problem. We decided to replace the metal filter - this time delivery was a bit quicker at one week.
We love the X5 and with two new replacement parts, we feel the X5 is like new again. Bottom line: do not clean the metal filter in a dishwasher, no matter how tempting.
