Product review (2 stars): What happened to these filters?  Something has changed!
I have been buying these filters for several years for an older model Duracraft humidifer.  Of the two pictured on the box, mine is identical to the one in the back.  I have never had an issue with these filters in the years I have been using them.  The last set I bought look the same as previously, but they are not operating as they should.  They will not wick the water to the upper half of the filter which is mandatory for it to be misted into the room. I have had this humifidier for enough years that I know I am doing everything right as far as cleaning and adding the water. Something has CHANGED with the composition of these filters.  I hope the company reads this and will remedy this situation.

Update: I ordered HAC-801 Honeywell filters which you can also buy on Amazon,and they are working perfectly.  The issue has to be with the manufacturer of the others changing the way they are made.  Of course, the Honeywells are twice as expensive, but they do work!
