Product review (5 stars): Register humidifer filter
I bought the original humidifier heat vents at a local hardware store, but when it came time to replace the filters I couldn't find them anywhere!  So I went to amazon to see if they had them and lo and behold there they were!  Now I know that amazon truly stocks everything!  Those humidifier vents make a big difference in my home and I didn't want to go without them!  It gets very dry here in the winter time and the last thing you need is to be full of static around sensitive electronics!
