SIZE and USAGE
the price was just right, but the fit was a little bigger than ordered for my humidifier model. I was, however, able to fold the filter inward to make it fit fairly well. I have been using every night for over a month and a half since I received the filter and to date it has not gotten brown, where I had to change it out. I was basically satisfied.

I was replacing a decades old pair of filters with little hope of getting correctly sized replacements, but called anyway. Within 5 minutes I had found and purchased the exact filters I needed, and they arrived on time as promised. They are bright and shiny with no smell of old grease, and for perfectly! Amazing.
