Product review (2 stars): Disappointed
The good: These filters arrived quickly and they "work" in my humidifier.
The not so good: Because the filter comes in a folded packing, it doesn't curve smoothly to fit into my unit. After installing, it didn't seem to be working well so I opened my humidifier to try to adjust the filter. I found the filter was soggy and unable to stand upright. It was like a wet noodle and just sort of caved inward. The filters need something to give them some kind of support. I then emptied the humidifier and installed another new filter, of which I got only a couple of weeks use before the amount of moisture put into the air was greatly reduced. I'm hoping I can reuse the first one when it is dry. It definitely does not last as long as others I have purchased. I won't be purchasing again.
