Product review (3 stars): not really the right size but can modify...
The packaging says this is for the 2H00 model right on the front, but it is bigger than the original filter. Checked the model no. on my humidifier just to make sure i hadn't made an error. The picture on amazon & original was blue and white, but ones i recd were white and seemed different. I had to trim half an inch off to fit my graco humidifier. So u really are not able to "drop in" as stated on description.
