Whole Home Humidifier and Humidistat

The HE240D Whole House Humidifier is easily installed on your current furnace by mounting on either the warm air supply or return air duct of forced-air furnaces to distribute moisture throughout your home.
The humidifier replenishes moisture throughout the entire home to help protect wood floors and furniture from drying and cracking, and can reduce static electricity to help keep your home more comfortable.
Ideal for homes: 1,500-3,000 sq. ft.
With the included digital humidistat with outdoor sensor acting as controller for your new humidifier, you can set your desired humidity level — and forget it as the unit turns on and off automatically to maintain your preset.
Must have access to a floor drain and full access to air ducts. Seasonal humidifier pad replacement required.

DIGI MISTER Evaporative Duct Mount Whole House Furnace Humidifier, Atomizing Cool Mist Variable Capacities for Homes and Offices from 1000 to 3500 sq. ft.

FLEXIBLE CAPABILITY. By changing the number of fine mist nozzles (1 to 5), adjusting the water pressure and the warm air temperature, DIGI MISTER humidifier can be used for homes and offices of various sizes from 1000 to 3500 sq. ft., as well as work with different types of furnaces.
EASY INSTALLATION. With a patented compact design this humidifier only needs a small cut-out for installation and can fit into a small area and tight space easily. No duct work and drainage is required, and the connection is simple and easy. A 24VAC transformer is required. Certain HVAC expertise is needed to perform the installation.
CONVENIENT MAINTENANCE. Through an observation window, users can visually check the water mist status to make sure for a complete evaporation. Spray nozzles can be conveniently tested and cleaned by using a nozzle tester away from the humidifier. With a “swing-out” design the spray nozzles can be replaced effortlessly. The package includes extra replacement nozzles. Users must ensure that the water pressure is adequate, and all nozzles spray fine atomized water mist.
FULL DIGITAL CONTROL. Users can precisely set and adjust room humidity, duct air temperature, as well as many other secondary parameters, such as humidity value calibration, temperature unit between °F and °C, etc.
WATER, ELECTRICITY and Money SAVING. Water is sprayed into the duct under a suitable water pressure (>30 psi) to form an atomized mist which fully evaporates into the air, with no wasted water running off and down the drain. No high water pressure pump, no power fan or high wattage electrode are needed for a very quiet operation and no more evaporative water pads or expansive steam canisters to buy once every winter season.
