Product review (2 stars): These could definitely be better...
I wish these things weren't so expensive, I've looked everywhere and they're pricey no matter where you go. Buying them in bulk is definitely the best way to save money. I don't really care for the material these filters are made of, I try to clean them every week and change them monthly as the humidifier unit advises. These filters fall apart after the first cleaning. Very delicate.
