Mitsubishi Electric Lossnay quietly removes stale, humid air from inside your home and replaces it with fresh, filtered outdoor air.
Unlike simple extraction systems, Lossnay recovers heat from the outgoing air and transfers it to the incoming air stream, helping maintain a comfortable indoor temperature while improving air quality.
The system can be programmed to suit your lifestyle, running harder when your home is occupied and reducing airflow overnight to maximise efficiency and comfort.
Not every home has ceiling space for a full ducted ventilation system. That’s where the Mitsubishi Electric Lossnay VL100 Wall Mount comes in.
This compact unit delivers fresh, filtered air into a single room — while recovering heat from outgoing air to keep your comfort (and energy bills) steady.
• Townhouses, granny flats, sleepouts, and studios
• Bedrooms or home offices that overheat in summer
• Small homes or retrofits where ceiling space is limited


Mitsubishi Electric Lossnay Wi-Fi Control is the smart evolution in fresh air ventilation.
With optional Wi-Fi control, you can monitor and manage your system from your phone — making it easy to keep your home performing at its best. See by how many degrees Lossnay is pre-warming or cooling your home via the App in real-time.
The Lossnay RVS and RVX3 Models have the option of an additional CO2 sensor. When connected with the optional Wi-Fi Control Adapter, CO2 levels can be viewed in real-time making it ideal for schools, medical facilities and offices.
Many Mitsubishi Electric ducted systems can be upgraded with Lossnay ventilation.
This allows you to introduce fresh air throughout your home using much of your existing ducted infrastructure, making installation simpler and more cost-effective.
It's one of the easiest ways to improve air quality, reduce condensation, and enhance the overall comfort of your home.
