Mechanical extraction ventilation (MEV) is another method that building owners can implement to extract excess moisture from wet rooms, like bathrooms and kitchens. To do this extractor fans must be ducted throughout a building to an exhaust on the outside of the property. From here, the stale air is ejected.
While this technology can improve your air quality score, it still relies on natural ventilation to keep inside conditions renewed; as a consequence, valuable heat energy is lost.
