Residential Ducted Lossnay®
Bring outdoor air into your home without opening a single window.
Residential Ducted Lossnay is a compact energy recovery ventilator designed to provide a balanced, whole-home solution by bringing filtered outdoor air inside and helping to exhaust stale indoor air. Lossnay easily integrates with Mitsubishi Electric ducted heating and air-conditioning systems to support a more complete approach to energy-efficient comfort.

A modern solution for modern homes
Homes built after 2010 are increasingly airtight, creating an unpleasant, often humid environment with stagnant, stale air. Many modern homes prevent contaminants, moisture, and odors from properly ventilating out of the home. While tightly built homes are great for energy efficiency, they fail to add ventilation to the home and lower the overall air quality.

Ventilation of the future
Bring filtered air into your home without relying on open windows.
Residential Ducted Lossnay is designed to integrate with ducted systems to bring in filtered outdoor air and move stale indoor air out. As an Energy Recovery Ventilator (ERV), Lossnay transfers energy between incoming and outgoing air streams, helping reduce the heating and cooling impact of ventilation compared with bringing outdoor air directly into the home. This system is able to maintain up to 90% of the heat energy in hot or cold climates.

Balanced Pressurization
Exhaust devices like bathroom fans can create negative pressurization. This can pull unfiltered, unconditioned outdoor air into your home through gaps in doors and windows.
Residential Ducted Lossnay supports a more comfortable, efficient home by maintaining balanced airflow and air pressure, reducing the impact of outdoor humidity and unfiltered air on your indoor environment.


High-quality air
Residential Ducted Lossnay® units are listed in the Home Ventilating Institute Certified directory to support residential ventilation code requirements when properly designed and installed. The HVI Ratings Program provides independent verification of performance metrics.
Systems include a MERV 10 filter, with an optional MERV 14 filter. The MERV filter number, or Minimum Efficiency Reporting Value, indicates air quality, as the filters capture and remove finer contaminats in the air. The higher the MERV rating, the more contaminants are filtered from the air.

ERV vs HRV
The right ventilation system can help create a more comfortable home year-round. While HRVs primarily transfer heat and are ideal for colder climates, ERVs transfer both heat and moisture energy, offering a more balanced approach to maintaining indoor comfort through changing seasons.
Lossnay systems also include an optional CO₂ sensor that allows the system to automatically adjust airflow based on indoor CO₂ levels. This helps to provide ventilation when occupancy and indoor conditions change.
