And, you can count on the drain and fill valves of this unit to work together to maintain proper water levels in the canister.

Water filtration is never required for you to enjoy the lasting effects of this digital humidifier.

Proper Maintenance For Your Humidifier

We live in Denver, and my skin used to feel dry all the time especially during the winter

We live in Denver, and my skin used to feel dry all the time especially during the winter. I was also always thirsty. I got this unit two weeks ago and I'm so miffed that I didn't get it sooner, could have saved myself a lot of trouble. I am now considering getting one for my office.

is the april air 800 available with a distributer that can be mounted on top of the unit so you can mount the unit on the wall and humidify the room that it is in...we want to use it inside a small room that is an IT room to hold the humidity up ...if this unit does not have it does one of the commercial models have this option?

by Dave B. on 07-16-2012

The Aprilaire 800 is designed for whole building use, and connects to your HVAC system. 

The Aprilaire 700 (click here to view) has a built-in power fan and is designed to provide humidity control for a standard household. If the room is small, you may not want a unit as powerful as the Aprilaire 800, as it may produce either too much humidity per volume of air, or may be inefficient.  

The aprilaire 700 can be wall mounted to distribute directly in the surrounding area
