Product review (5 stars): Better than the OEM
I purchased this to replace a really dirty filter and to my surprise it functioned much better that the original.  The original had a tendency to dry out, preventing the machine to create humidity. This filter is not plagued with this problem; even after not using the machine for a week the filter keeps moist.  I loved this product so much I got a second one for another machine which had a OEM filter that was practically new.  Now both machines are constantly operating as designed.
