Product review (3 stars): It works... Kinda
Bought 3 of them for my MoistAIR humidifier, and they worked fine for a few weeks, then I got a "Change Filter" beacon on my humidifier which I thought was weird since the filter was less than a month in the machine, but I changed it anyways and the beacon still has not gone off. I think these filters are meant to work with different humidifiers and not with moist air ones, my humidifier is still working, but it isn't recognizing that I have a perfectly good clean and new filter in it.
