Product review (2 stars): Inadequate
These filters are  the thickness of the factory filter. They do fit the filter tray, but with a lot of extra room, unlike the factory filter that fills the tray well. They are too thin to wick enough water to keep up with the humidifier. As a result, they are considerably less effective. The metal mesh used on this is very different than the plastic of the factory version and a little harder to work with. They will work, but not as well. I would only buy these again if the factory one wasn't  available anywhere.
