Product review (1 stars): ... in my humidifier and apparently they do not wick like they should
I put them in my humidifier and apparently they do not wick like they should.  I have a needle gauge that is in green when filters are working well and red when they are dirty.  The new filters were installed in the unit 5 hours ago and the needle has not moved from red meaning no wicking.  Not happy at all with the product.
