Product review (5 stars): These filters fit exactly and work efficiently.
We are using our wood stove more these days and I needed to be sure I keep the house properly humidified. The filters came sooner than expected and fit perfectly. Also, the filter seems to be wicking better than the original filter. I fill my reservoir 2 times during the day now vs. 1 time a day with the original filter. I don't mind because I know that the humidifier is doing its job. No product dislikes after one week use.
