Product review (4 stars): good filter
I run 2 large humidifiers all winter long and these filters do hold up but have to be changed about every 2 months.
I think for what these filters are made of and the fact that they have to be thrown away, they should be prices a bit cheaper!
It would be great if one could be designed that was reusable!
I do rince these filters from time to time to remove surface dirt and the stray pet hair that gets sucked in. It seems to help with their longevity.
