NuTone ULTRA Motion Sensing Fans deliver everything you wished for in a bath fan premium ventilation to help reduce airborne pollutants, ease of installation, energy efficiency, consistent power, extremely quiet operation and multi-speed capability. Best of all, they have the ability to know when they should be in the normal continuous ventilation mode and when they should kick up to the high speed mode to evacuate shower humidity or odors.80 CFM quickly reduces humidity to prevent or eliminate fogged mirrors and manage moisture in bathrooms up to 70 square feet, so your vision will always be clear and your surroundings will always be comfortable ULTRASense M, Motion Sensing Technology, offers a hands-free solution for maximum convenience.
