Vehicles from California are known among experts to be relatively free of rust. The dry climate there means cars are still in good condition even after 20 years or so. But in Europe, car-lovers have to protect their valuable historical vehicles actively against rust and corrosion. AERIAL air dehumidifiers reduce relative air humidity, meaning rust and mould don’t stand a chance. Nor do you have to worry about drying out: wood, leather and rubber all remain intact, because all AERIAL dehumidifiers are controlled fully automatically by their own hygrostats. That is why so many oldtimer enthusiasts in Europe rely on AERIAL products.
