Product review (1 stars): Horrible replacement filter
I bought this replacement filter because the Sears replacement filters are very expensive in comparison. On the second day I had this filter, I started getting "check filter" errors - the filter had already stopped absorbing water. I had to flip the filter a couple of times per day to keep it even slightly wet. I'm going to pay the extra money to get the Sears brand filter and then start looking for another humidifier with a better design.
