Product review (1 stars): Be Careful- Does not work with Humidifier shown
This ad makes it look like it fits the humidifier pictured, but the filter is for a 1155 the humidifier pictured is a 1115. Of course I didn't notice that until it arrived and it did not fit. You can cut it to make it work, but it is hard to cut and there is a lot of waste. Amazon really flubbed this one, so be careful!
