The Mitsubishi Electric Lossnay System is a patented heat recovery ventilation solution that uses fresh air (not attic air) to ventilate your home. The system works by extracting stale air from inside your house and replacing it with allergen-reduced fresh air from outside. Lossnay also recovers heat energy from the air being transferred to pre-warm (or pre-cool) the fresh air being drawn into your home.
