Product review (1 stars): These are terrible
These are terrible. I had a set of these that came with the humidifier and then used a set meant for another model that I could get in store. Both only needed replaced about once a year. Decided I'd order these this time so they were right. The pictures are after one week of use. They are hard on all edges and shedding material on the under side. It's gross, they were expensive, and they arrived very far outside the date. Never again.
