So happy to find this kit
I needed to replace my tube feeder and humidifier filter and I was thrilled to find this on Supply House. This is a great place to find supplies. Received it fast and was inexpensive and easy to install.
thank you

Good kit, good price.
We were able to get our broken Aprilaire 550 up and running again. Instructions were clear and easy to follow, and it came with an owner's manual for the unit.
Price was right, and it shipped quickly.
