HI Quality, quick delivery. This was installed in the ceiling and it looks great, we tried another brand and the other brand could not even support its own weight.

I purchased the Aprilaire 500 whole house humidifier. Humidity is adjusted automatically based on the humidity in the house and the temperature outside. I was looking for a reliable product that does the work for me so I don't have to constantly adjust the setting manually. The weather is very dry in the winter where I live. This unit was the answer. Very easy to install. Installation instructions are easy to understand. product works great. Highly recommended.
