Product review (2 stars): Doesn't work well as a Kenmore replacement
Generally I am an avid review reader, but I must have been in a hurry when I purchased these.  Though less expensive than the Kenmore brand they do not absorb water as well; like other reviewers I began getting "check filter" messages as the humidifier "realized" that it was taking too long to increase the humidity level.  I also had some success in flipping the filter over (bottom to top) to help things along, but it still didn't really do the trick.  Additionally, because the water in the bottom of the humidifier was not getting evaporated as quickly it became quite stagnant and cloudy, a problem I never encountered with the Kenmore filters.  I ended up doubling up on filters (since I purchased 3) and it seems to be working well...but that negates any cost savings over the Kenmore brand.
