The Aprilaire 800 Steam Humidifier is a whole house humidifier with digital control. Capable of humidification of up to 6,200 feet, it utilizes some of the most advanced and groundbreaking technology to ensure your breathable air is always at the proper humidity levels. The Aprilaire 800 delivers humidity in the form of steam to a conditioned space OR using the optional Aprilaire 850 Pack.

Installation is easy with the Aprilaire 800 recessed into a wall. In addition, maintenance is also easy with no cleaning or scrubbing! All that is required is for the canister to be removed. This humidifier uses the latest in absorption and dispersion steam technology to properly dispense air throughout your entire house without causing problematic condensation in your ducts. You can count on the drain and fill valves of the Aprilaire 800 to work together to maintain proper water levels in the canister. This allows for the unit to deliver the correct steam capacity based on the electrical conductivity of the water. Water filtration is never required for you to enjoy the lasting effects of this digital humidifier.

When the humidity levels in your home are at an optimal level you provide an environment that is ideal for respiratory health.  Another benefit of optimum humidity levels is protection for parts of your home that can be damaged by dry weather (paint, weather stripping, molding, etc.). Your electronics such as TV and computer.

The Aprilaire 800 Humidifier should be inspected approximately every 500 hours.  Check and inspect the piping and plumbing connections for leaks or cracks.  You should also check the drain line to make sure it is not blocked, and clean or replace as necessary.

Adding humidity by means of steam is one of the newer and efficient ways to solve the issue of dry air within your home.

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?

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
