DIGI MISTER Atomizing/Evaporative Duct Mount Whole House Humidifier with UV-C LEDs, Variable Capacities for Homes up to 3500 sq. ft.
DIGI MISTER

DIGI MISTER Atomizing/Evaporative Duct Mount Whole House Humidifier with UV-C LEDs, Variable Capacities for Homes up to 3500 sq. ft.

Why we love it
  • Flexible capability for diverse spaces.
  • Effortless installation in tight areas.
  • Precise digital humidity control.
Main Highlights
  • FLEXIBLE CAPABILITY. By changing the number of fine mist nozzles (1 to 5) and adjusting 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 are required, and the connection is simple and easy. A 24VAC transformer is required, or an all-inclusive DIGI MISTER humidifier installation kit will make the job much easier. 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 residential 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.
  • 260-280 NM WAVELENGTH UVC LIGHT. Eight (8) UVC LED lamps equipped on the DM538 humidifier will be turned on whenever the humidifier is powered up. Customers may have this function even in summer when the AC is running.
