Product review (5 stars): Great filter!
These filter work perfect in my humidifier and are much better than the ones made by the manufacturer of the humidifier. They have an sturdy outer layer that helps them keep their shape so they don't fold over and fall down. I was about to replace my humidifier which I have only had for a year because I was so frustrated with the poor quality of filters. I am so glad I gave these a chance first. I highly recommend these!
