LOSSNAY^® Energy Recovery Ventilation

Modern homes are more airtight than ever, improving energy efficiency but also trapping indoor pollutants and excess moisture. LOSSNAY^® MX-Series Energy Recovery Ventilation (ERV) continuously brings in fresh outdoor air while exhausting stale indoor air to help create a healthier home environment.

Energy-Efficient Fresh Air

Mitsubishi Electric's patented energy recovery core transfers both heat and moisture between incoming and outgoing airstreams, reducing the energy needed to condition fresh air. With adjustable airflow from 40 to 110 CFM, LOSSNAY^® delivers balanced, energy-efficient ventilation year-round.

Quiet, Smart Performance

A proprietary EC motor and advanced fan design provide whisper-quiet operation at sound levels as low as 25 dB(A). Optional CO₂ sensors can automatically adjust airflow based on indoor air quality, helping optimize comfort and efficiency.

Compact Design, Flexible Installation

With a slim 9.5-inch profile, LOSSNAY^® is designed to fit easily into space-constrained applications, and can be installed in a variety of configurations without requiring additional accessories. It is also suitable for installation between joists that are 20" or more.

Built for Canadian Homes

Engineered for cold climates, LOSSNAY^® features advanced defrost controls that help maintain reliable ventilation performance in outdoor temperatures as low as -25°C.

Flexible System Integration

LOSSNAY^® integrates seamlessly with Mitsubishi Electric heat pump systems, including Zuba-Central, M-Series, P-Series, and CITY MULTI® systems. It is also compatible with third-party controls, sensors, thermostats, and air handlers, providing greater flexibility for residential applications.

The result is a healthier, more comfortable, and energy-efficient home with fresh air delivered year-round.
