Type
There are two basic humidifier types: bypass and power fan. Each simply uses a different method to move air through them. Power fan humidifiers use a 110 volt fan to move air through them. Bypass humidifiers do not have a fan, but instead require a 6” duct to be connected to the side and then to the opposite air duct system from the humidifier. That means for bypass models that if the humidifier is installed on the supply plenum, the 6” duct will connect to the humidifier and the return plenum, and if the humidifier is installed on the return plenum, the 6” duct will attach to humidifier and the supply plenum.
Both humidifier types – bypass and power fan – will provide the same benefits to you. The only difference is the technology used to do so. The advantage to power fan models is since they do not require additional ductwork, they can be installed faster and in tighter spaces. The advantage to bypass models is that they cost a bit less. |

Maximum Coverage Area
Maximum coverage area means this humidifier will perform well for home sizes up to the square footage indicated, provided that the home is “tight”. A tight home is typically is one that is sealed well around windows and doors and does not leak air to/from the outdoors. Note that humidifiers will perform well for smaller homes as well since the controller regulates the amount of humidity automatically to adjust to home size. |

Electrical Requirements
Humidifiers with 24 volt AC electrical requirements obtain such by connecting to either 24VAC from the furnace, or by adding a transformer to the furnace to create such. Most installations can use the 24VAC that is already accessible in the furnace.
Humidifiers with 110 volt AC electrical requirements simply plug into a standard outlet (receptacle) and require no special wiring for this part. It is recommended, however, that the outlet/receptacle be dedicated for the humidifier, and that it can be shut off by the same power safety switch that turns off the furnace.

Remote Sensing Bulb
A remote sensing bulb is a small (about ¼” round) sensor that mounts outside the home and connects by light gauge wire (18 to 22 gauge, 2-conductor) to the humidifier controller. This sensor provides temperature readings to the computerized controller which allows the humidifier to automatically adjust humidity levels in the home based on outside air temperature. |
