Product review (1 stars): Not so great
These filters fit into the frames of my humidifier, but that's about the only good thing I have to say about them. I normally get a full season out of a set of humidifier filters, but these showed a severe drop in wicking performance after about three weeks' use. Even last year's used filters still perform better than these when it comes to drawing water out of the humidifier tray and putting it into the air. Disappointed. Won't buy these again.
