The tighter we seal our houses to reduce utility bills, the worse our air quality becomes. The WhisperComfort Spot Energy Recovery Ventilator (ERV) pulls stale air out of the house, just like a bathroom exhaust fan. At the same time, it pulls in fresh air from outside. A "capillary core" inside the unit warms and humidifies cold incoming air, so your heating bills and nasal passages don't take a hit in the winter. A sensor, programmed in accordance with the defining industry standard for indoor air-quality (ASHRAE 62.2), activates the ERV's quiet, efficient DC motor. Unlike expensive steamer-trunk-sized units that work only when connected to a forced-air system, the compact, microwave-sized WhisperComfort can be used with any kind of heating system. Panasonic recommends placing them in strategic locations around the house, particularly in moisture-heavy areas such as kitchens and baths.
