Review on Aprilaire 4839 Humidifier Maintenance Kit - Water Panel Model No. 35 Replacement filter for Models 600, 600A, 600M by Greg Cunningham

If you need to replace the water bezel hardware for your Aprilaire humidifier, this is your option. It comes with all the necessary parts to replace the internal parts of our humidifier. After a few seasons, ours was heavily mineralized. Finally, it's time to just replace it, not clean it. The instructions are clear and it installs easily. The only tools you will need are an adjustable wrench (or something to loosen/tighten the drip line compression fitting) and possibly scissors if your drip line is too long. I really wish it was a little cheaper, but I think most of that is the panel itself.
