Lossnay Ventilation

Mitsubishi Electric Lossnay domestic ventilation systems are the ultimate solution for maintaining a healthy home through high level of indoor air quality. The Lossnay system removes stale air and any pollutants from inside the house, and replenish it with fresh, filtered air from outside. At the same time, it recovers the heat energy from the extracted air and transfers it to the supplied outside air to maintain the indoor air temperature and humidity as efficient as possible.

Naturally fresh filtered air

These Lossnay domestic ventilation systems are designed to provide continuous extraction of stale air from bathrooms, kitchens, toilets, laundries and other parts of the house that can become contaminated with chemicals, fumes and odours.

The Lossnay supplies a balanced flow of fresh air from outside to living spaces such as bedrooms and living rooms. Whilst doing this the unit minimises the energy lost by recovering the heat from the extracted air and transferring this to the supplied fresh air.

Optional higher grade filters are available to provide better filtration of incoming air. Perfect for homes that are located in high density area or prone to air pollution.

Innovative heat exchange

The Lossnay Energy Recovery Ventilator is a smart solution that helps you avoid wasting energy when ventilating a room with an air conditioner. Picture a hot summer day when you want to bring in some fresh outside air to a comfortably air-conditioned room. The problem is, if you just open the windows, the hot air from outside will make the room warmer and more humid. To counter this, you might end up cranking up your air conditioner, leading to higher electricity bills.

Here’s where the Lossnay ventilation system comes in handy. It allows you to bring in fresh air without compromising the cool, dry atmosphere you want in the room. Essentially, it stops energy from escaping during ventilation, helping you save on electricity.

The key component in the Lossnay Energy Recovery Ventilator is the Lossnay Core, a special heat exchanger developed by Mitsubishi Electric. This core uses partition plates made of specially processed paper (or plastic for some models) to keep the exiting room air and the fresh outside air separate. While it allows the transfer of temperature and/or humidity, it prevents the actual flow of air. The concept for this technology came about when an engineer, inspired by his daughter playing, rolled a sheet of paper into a tube and blew air through it. He noticed that the heat transferred through the paper, giving rise to the idea behind this innovative system.

Tailored ventilation solutions

Whether you are looking for a standalone Lossnay ventilation system or integration with your existing HVAC setup, Mitsubishi Electric offers versatile options to suit your needs. Our systems are compatible with split system air conditioners, ducted systems, and more, allowing you to create comprehensive indoor climate control and ventilation strategies.

  • Pedestal fan: Providing reliable air circulation, our pedestal fan ensures a consistent, comfortable atmosphere. It features adjustable heights and multi-speed settings, making it suitable for various room sizes and layouts.


Lossnay ventilation system  comprises of an outside air supply fan, an exhaust air fan and a heat exchanger  There are two separate airflows inside the unit to supply outside air and extract stale air. They are both passed through a heat exchanger to retain the heat energy from the extracted air and transfer it to the incoming outside air.

Unlike traditional ventilation systems, Lossnay ventilation combines advanced heat exchanger with mechanical ventilation system. It supplies fresh air effectively while recovering heat energy from the extracted stale air, offering superior indoor air quality and energy efficiency.

Mitsubishi Electric Lossnay ventilation systems can be seamlessly integrated with Mitsubishi Electric ducted systems, providing a comprehensive solution for indoor air quality and climate control.

Mitsubishi Electric offers a range of Lossnay ventilation models, each designed to cater to specific ventilation needs and space requirements. The choice of the Mitsubishi Electric Lossnay ventilation model depends on the size of your space, your ventilation requirements, and any specific features you prioritise.
