Product review (3 stars): Works, but not as expected.
I purchased these filters for my Sunbeam Humidifier, SCM3609. However, when I tried to install them, I noticed they were not the same inner diameter as the old filter. I was able to make them work, but I had to stretch the filter out and form the wire wrapping the filter has to get into the humidifier tray. It only took about 3 to 4 mins to get it stretched out enough that it would seat inside the tray. I've cross referenced these filters with other manufactures and they all appear to have the same inner diameter, which appears incorrect. Once installed, the filters worked.
