The Energy Star® rated Ultra-Aire 120H is designed to deliver exceptional indoor air quality by providing dedicated moisture control, fresh air mechanical ventilation and superior air filtration (MERV 13) to the entire home. The unit will dehumidify areas up to 3,000 square feet and features an extremely well-insulated, compact horizontal cabinet for the ultimate in quiet operation.

Optional fresh outdoor air may be ducted to the unit via a six inch round duct. This provides fresh air to dilute indoor pollutants and maintain high oxygen content in the air. The amount of fresh air ventilation can be regulated by a variety of dampers and controls.

The Ultra-Aire 120H includes air filtration to improve indoor air quality. A MERV 13 media filter is standard. An optional external MERV 14 filter box and deep pleated 95% media filter is available for optimum air filtration to reduce potentially harmful airborne particles. If the optional filter is chosen, a standard filter operates as a prefilter.
