Developed in Finland, tested in Nordic conditions
Mobair's mechanically assisted ventilation system installs in new or existing buildings to handle all ventilation or supplement your current solution.
Do you recognize these indoor air problems?
Difficulty lighting the fireplace
The fire catches but smoke soon fills the room. The cause is often insufficient replacement air — a fireplace needs proper ventilation to work correctly.
Poor sleep
Poor indoor air disrupts sleep and can cause headaches. Carbon dioxide levels in the bedroom rise overnight if fresh air is not supplied adequately.
Condensation and moisture on windows
Moisture builds up in structures slowly and unnoticed. Insurance rarely covers gradually accumulating damage.
