good filter
I have had several different filters and i find this one is better because the black coating on the out side helps it keep it shape especially when it is very wet! I have several different humidifiers through out my house and have now starting only buying these filters for all of them. Durability some of the filters I have bought need to be replaced 2 sometimes 3 times during the season, these ones do not they last the entire season!
