Clean and fresh air coming out from the AirMaster !

1. Air purification :
Removing 99.9% of harmful substances such as fine dust, formaldehyde, etc. by using the ECO filter
2. Aqua anion :
Room full of aqua anions coming out from the waterfall –
3. Natural humidification :
Maintaining proper indoor humidity by the natural evaporation humidification



     AirMaster structure

1.Fan :
Moist moisture particles containing anions are emitted by the fan.

2. ECO filter :
Ionized contaminants flow down sticking to water on the surface of ECO filter and only ionized fine moisture particles go up to the fan.

3. Ionizer (Anion generator) :
Contaminants in the air entered by the force of fan are ionized passing through the ionizer(Anion generator).

4. Water tank :
The water contained in the tank moves to the ECO filter.
