Product review (5 stars): Carrier furnace humidifier pad
I ordered this replacement pad from Amazon. It was easy to order and arrived in one week. I ordered 2 and kept one for next year. It was easy to install. The top of the plastic frame comes off and the new pad is easily inserted. To put the top back on it just clicks together. I tried getting this pad from the dealer, but they were not interested without an expensive service call to install it in the humidifier.
