Every home deserves fresh, filtered air — and the comfort of knowing it’s being delivered intelligently.
As modern homes become increasingly airtight in the pursuit of energy efficiency and thermal performance, a new challenge has emerged: trapped moisture, stale air, and unseen pollutants.
The Mitsubishi Electric Lossnay Fresh Air Heat Recovery Ventilation system is designed to meet this challenge — offering discreet, energy-smart ventilation that preserves your home’s comfort, health, and architectural integrity.
Why Ventilation Matters More in Today’s Homes
Superior insulation and double glazing help maintain warmth, but they also prevent airflow. In high-performance homes, this can lead to poor air quality, excessive moisture, and condensation — all of which impact health and long-term building performance.
Lossnay provides a seamless solution: filtered, tempered fresh air that’s gently introduced into the home, while stale, humid air is continuously extracted. And with whisper-quiet performance and Wi-Fi control, it’s built to enhance your lifestyle, not interrupt it.
Protect Interiors: Eliminate Condensation and Mould
High-end finishes, timber elements, and natural materials demand a dry, stable environment.
Lossnay works continuously to remove excess indoor moisture — stopping condensation on windows and walls before it starts. By managing humidity levels, it protects your home’s interior detailing from the effects of mould and moisture damage, particularly in wet areas like bathrooms and laundries.
Energy Efficiency Through Heat Recovery
Lossnay doesn’t just ventilate — it recovers up to 90% of the heat from the outgoing air and transfers it to the incoming fresh air. This significantly reduces energy waste and keeps your home consistently warm and inviting with less strain on your heating system.
In summer, its Automatic Free Cooling mode draws in cooler outside air at night, helping regulate indoor temperature naturally and passively — without requiring additional mechanical cooling.
A smart choice for homes focused on comfort, sustainability, and operational efficiency.
Control Air Quality from Your Phone
The Lossnay Wi-Fi Control App allows homeowners to monitor and manage air quality in real-time — from anywhere.
With the app, you can:
• See how many degrees the system is pre-warming or cooling your air
• Monitor temperature reduction in summer through Free Cooling
• Receive proactive filter maintenance reminders
• (Optional) Monitor CO₂ levels with an additional sensor — ideal for home offices or multi-room zones
This brings a new layer of visibility and control to a function that’s often invisible — but critical to wellbeing.
A Healthier Home for Allergy and Asthma Sufferers
For families affected by asthma, allergies, or general respiratory sensitivities, air quality is not optional — it’s essential.
Lossnay’s filtration system removes common airborne irritants like pollen, dust, and particulate matter. It ensures that the air entering your home is fresh and filtered, dramatically improving comfort for children, elderly residents, and anyone with respiratory concerns.
Designed to Complement Architecturally Considered Homes
Lossnay systems are compact, silent, and easy to integrate into both new builds and architectural renovations. Whether vertically installed in a cupboard or fitted into ceiling spaces, they operate seamlessly in the background — without disrupting the visual flow of the home.
The system pairs well with ducted heating and cooling, making it ideal for whole-home air management. It also aligns with New Zealand’s Healthy Homes Standards and sustainable building practices.
Quietly Powerful. Visibly Better.
Mitsubishi Electric’s Lossnay system represents the next evolution in high-performance home comfort. It’s not just about ventilation — it’s about creating a living environment that supports health, enhances energy efficiency, and preserves the beauty of your home.
