Self-contained ventilation and air purification

Air purification and ventilation in one unit — the Marta from JS Air Conditioners.
The Marta air purifier and room-ventilation unit from JS Air conditioners draws in fresh air from outside, purifies it and heats it before releasing it to the room. Marta units can serve rooms up to 45 m2. A 125 mm-diameter hole is drilled through the wall, and the Marta is fixed over it. A carbon filter removes odours and gases like sulphur dioxide, oxides of nitrogen, benzene, diesel and ammonia. An F9 filter captures up to 99.9% of particulate matter. An internal 800 W heater can be switched on to temper incoming cold air in winter. Room air is also recirculated, so that it is filtered and its quality maintained. The balance of fresh air and recirculated air can be controlled. Three fan speeds provide 40, 0 and 120 m3/h. Noise level at the lowest fan speed is less than 23 dB(A).
