What Is Mitsubishi Electric Lossnay?

Mitsubishi Electric Lossnay Fresh Air Heat Recovery Ventilation continuously replaces stale indoor air with filtered outdoor air while recovering heat energy from the outgoing air.
  • Brings in fresh, filtered air to help reduce moisture, odours and airborne pollutants.
  • ​Uses a special heat recovery core to pre‑warm or pre‑cool incoming air, reducing the load on your heating and cooling system and helping lower power bills.
  • ​Ideal for airtight, energy‑efficient Christchurch builds where condensation and indoor air quality can be a challenge.
