Product review (3 stars): An Almost Miss
I agree with the pros and cons of the other reviews.  The price is certainly nice but there are enough drawbacks that I am going back to ordering true KAZ filters.  First off, this filter needs to be cut along the seam line to fit into my 3000 series evaporative humidifier.  To begin with the filter seemed to work just fine but after a couple of weeks the wicking feature does not always work.  It could be my water but the old KAZ filters lasted for a long time using the same water.  The material itself seems to be flimsy and not as rigid as the original ones.  I love this evaporative humidifier because it does not spew water droplets into the air and only puts moisture in the air when needed.  When I look for a replacement/(possible second unit) I cannot find a company which makes this kind of filter.  Would love to know if anyone has found one.
