Users' feedback

Users quotes on Amazon.comI wish we had bought this before! We live in the dry desert and humidity is very important in the winters. Previously, we had used a "whole house" console. The whole house, my ear! It barely let out enough humidity for the room where it sat. It was loud, you had to refill the water daily, it was a huge pain to clean, you had to buy pads once a month, and it stunk unless you used harsh chemicals. We hated it. We bought this humidifier on a friend's suggestion and though the installation was intimidating (cutting holes in my ductwork), it was actually quite straightforward and not difficult. "

Users quotes on Amazon.comIt is difficult to install and uses too much water."

Conclusion: 600 by Aprilaire

The Aprilaire 600 humidifier is amazing and perfect for tightly sealed houses, both large and medium-sized. It stands out from many other humidifiers by the fact that once connected to the cold or warm water, there is no need to keep refilling it every now and then.

On the other hand, this humidifier has been said to be a technical one to install and unlike other humidifiers, an HVAC technician may be needed to ensure proper installation. The fact that it uses much water, 17 gallons a day, may not be so good for people living in areas where water is a bit costly.

However, this humidifier functions quite well and is a good fit for entire house humidification that you should always have.
