Whole-home climate control with discreet ducted units, grilles, and smart controllers.
The Lossnay is the ultimate home ventilation system, delivering fresh, clean air from outside rather than attic spaces. With its advanced sensible Diamond Heat Exchanger, it removes moisture and stale indoor air while efficiently recovering heat from outgoing air and damp areas like kitchens and bathrooms. This recovered heat is then used to pre-warm (or pre-cool) incoming fresh air, reducing the workload on your heating or cooling system to effortlessly maintain the desired room temperature.
The Mitsubishi Electric Lossnay Wi-Fi Control takes your fresh air ventilation system to the next level with real-time visibility, smart performance, and proactive alerts – all from the convenience of an app. Whether you're pre-warming your home in winter or cooling it naturally in summer, Lossnay makes comfort smarter and cleaner. With added features like filter reminders and optional CO2 monitoring, it’s ideal for homes, schools, offices, and medical facilities. Available as standard with the Vertical Lossnay Series or as an upgrade for RVX3 and RVS models.
The Lossnay system brings fresh, filtered air into your home while recovering heat to keep things energy-efficient and comfortable year-round.
