Honeywell HE100A1000 - TrueEASE Basic Bypass Humidifier 12 GPD with Automatic HumidiPRO Humidistat

The Honeywell HE100A1000 TrueEASE Small Basic Bypass Evaporative Humidifier with automatic control covers up to 2,500 square feet and disperses up to 12 gallons per day.

The Honeywell HE100A1000 TrueEASE Basic Bypass Evaporative Humidifier is a great whole-home humidification solution that covers up to 2,500 square feet, and disperses up to 12 gallons of humidity per day into your home. The HE100A1000 TrueEASE humidifier will not only provide a solution to your dry air woes, but it is also an eco-friendly option that will conserve energy and water while doing so!


The basic bypass TrueEASE system will only run water and air through the system when humidity is needed, using up to 50% less water, and saving energy by eliminating the constant cycling of air.  


The Honeywell TrueEASE HE100A1000  bypass unit mounts directly to the duct of your heating and cooling system, allowing the humidity to be placed directly into the airflow and distributed evenly throughout the home. The HE100A1000 can be mounted on the supply or return duct (plenum) and is easily reversible for right or left hand installation. To switch the bypass to make a left handed install, simply remove the bypass, flip it and snap back into place! Additionally, this model will hook up to a water line so you do not need to worry about filling it multiple times a day.  


TrueEASE has a patented design with multiple snap-into-place configuration options, making installation a breeze. No longer will pipes, small compact spaces, water heaters or any other obstacles will get in the way of installation!  


The Honeywell TrueEASE whole-house small basic bypass evaporative humidifier features the automatic HumidiPRO humidistat control to ensure comfortable humidity levels throughout the home. The HumidiPRO humidistat should be installed directly onto your heating and cooling system&nbsp, preferably the return duct, if possible.


Maintenance: The only maintenance that needs to be done on the Honeywell HE100A1000 humidifier is the seasonal change of the Honeywell HC22E1003 Humidifier Pad. The humidifier pad can be easily accessed from the front or either side of the unit, and features a slide-out pad design, which means you won't have to disassemble the unit in order to change the pad.

*Important note: If you have hard water, the pad may need to be changed more frequently!
