Product review (5 stars): UF99013 Generalaire Humidifier filter
We had installed a humidifier on our furnace last year and were told that the filters need to be replaced yearly. We called at the start of this season to check the price of the new filter thru our Heating and A/C service company. It was double the price for the exact same filter! For just a little search effort, I received a great product at a fantastic price and it was shipped quickly and well packaged. I will definitely order this product thru Amazon in the future.
