Product review (4 stars): Fits into the humidifier, barely
After wiggling and squishing the filter, I was able to fit it into the humidifer. It works great, but I found that it grew mold faster than the one that came with the device. I bought two thinking they would last a few months, but so far, I ave gone through 1 in less than 30 days.
It takes several days to airdry, so if you need to pack it in a hurry, you are going to be out of luck.
