Maintaining the most comfortable humidity level helps keep germs and bacteria away, especially with the help of a whole-house humidifier like the General Aire 1042-LH bypass evaporative humidifier. As warm air from your furnace flows into the humidifier, it meets a water-soaked vapor pad, which evaporates moisture to deliver humidity throughout your home.
Note: This humidifier must be installed by a licensed contractor.
Manual Humidistat
Included with the General Aire evaporative humidifier is the MHX3C manual humidistat, featuring:
- Manual Controls: Simply turn the dial to your preferred humidity level.
- Design: A low-profile, contemporary design with solid construction.
- Flexible Installation: You can install the humidistat on your wall or directly on your duct with the General Aire humidifier.
- Humidity Range: This humidistat gives an extended humidity range from 10 to 75 percent.
Flow-Through Technology
The General Aire 1042-LH features the patented KineticFlo water distribution trough design to ensure the vapor pad is thoroughly and consistently moistened. As water flows through the trough, it is evenly dispersed across the pad, providing up to 19 gallons of humidified air daily. The Bypass Duct can be mounted to the left or right.
Additional Features
- Strong Construction: General Aire uses UV-stable automotive-grade plastic for this low-profile humidifier.
- Large Coverage Area: This evaporative humidifier covers homes of up to 2,800 square feet in size.
- Contemporary Design: This whole-house humidifier features a low-profile, space-saving design, making it lightweight and easy to install.
- Flexible Installation: You can install this bypass humidifier in one of several options: warm air plenum, return air plenum, right or left bypass, vertical or horizontal, or furnace or air handler.
Sylvane's Expert Take
If you're a homeowner adding whole-house humidification to a forced-air furnace in a home up to 2,800 square feet, the 1042-LH ties directly into your ductwork and must go in through a licensed contractor. Its bypass duct mounts left or right in almost any orientation, so your installer can fit it into a tight mechanical room.
The included manual humidistat covers a wide 10 to 75 percent range from a single wall- or duct-mounted dial, and the KineticFlo trough keeps the vapor pad evenly saturated for steady output. For straightforward, contractor-installed whole-house humidity, the 1042-LH is a dependable pick.
