It's suited for multiple room use, working in spaces up to 66 square metres in size.

The EVA Alto Nine Air Purifier is capable of working automatically. It does this by utilising a PM2.5 particulate sensor which measures the air quality and increases/decreases the fan speed accordingly. You can see the current air quality thanks to the four-colour indicator. The appliance also has a silent mode (outputting only 18dB of noise) and a scheduling timer.
