Ventilating Dehumidifier Provides the Ultimate in Comfort and Indoor Air Quality
The Ultra-Aire XT150H high capacity whole house dehumidifier removes up to 150 pints of water a day, provides fresh air ventilation and uses 6.9 amps (7.9 pints per Kilowatt hour). The unit is Energy-Star Rated and provides effective MERV 14 air filtration.
The optional fresh air ventilation feature, available on all Ultra-Aire ventilating dehumidifiers, allows fresh air to be introduced into the home when needed. This filtered fresh air significantly reduces concentrations of pollutants that were previously trapped inside the home, such as cooking odors, VOC’s from carpet or furnishings, and moisture from plants, pets and people. Managed fresh air ventilation removes that “stale air” smell by greatly improving indoor air quality for a more comfortable and healthier home environment. The Ultra-Aire ventilation function is controlled separately from the dehumidification and filtration, allowing ventilation to be customized for any application.
