Product review (2 stars): not the best
As Walmart no longer sells the original filter, a friend said to try Amazon.

I was thrilled to find some filters.  But, I should have listened to the other reviews that stated doubts. They are not up to standard.  Not regular in size---some too long and needed trimming.  They are not wide enough and start to lean and bent when they get wet.  Humidifers do not work as well with them.  Air can be heard flowing but water level does not go down which means to me that the water is not going into the room the way that it should.

I ordered 12 and will use them since I have them. But, I do not expect them to last as long as the originals and I have doubts as to whether I will buy any more.

I was very disappointed.
