The WhisperComfort is a new spot energy-recovery ventilator and the first ceiling-insert ERV in the United States, according to the manufacturer. The ERV exhausts stale air from inside the home and replaces it with fresh air from outdoors. The new WhisperComfort spot ERV fan series uses two ducts - one to exhaust stale air and the other to supply fresh air from outside. Its low-rate, continuous run helps ensure that volatile organic compounds and other chemical and biological indoor-air pollutants are vented out and replaced with fresh air. WhisperComfort technology provides continuous low-rate balance airflow to help improve indoor air quality. When air is brought in from the outside, the capillary core inside the WhisperComfort fan transfers heat and moisture to the supply air. This exchange both tempers the supply air coming in from outdoors and transfers moisture to maintain a comfortable indoor living environment. WhisperComfort model number FV-04VE1 has two, two-speed setting options: 10/20 cfm or 20/40 cfm.
