The most important job for a ventilation fan, particularly in a well-sealed home, is to exhaust the excess moisture from the air. Moisture needs to be kept from building up indoors to keep the interior environment comfortable. To help with this, Panasonic is introducing a new series of WhisperSense fans with dual sensors which will be available starting in June 2011.
