MY AIR uses Kaltec's unique photocatalytic technology to decompose and purify air pollutants, harmful substances, and viruses in the air, creating clean air. Furthermore, the airflow is set so that the amount of air a person breathes in one minute (about 7 liters) accumulates around the face. When the photocatalytic filter is irradiated with light, it becomes strongly oxidizing. By utilizing the strong oxidizing power of this photocatalyst, air pollutants and harmful substances can be decomposed. Clean air is emitted from the air outlet. The internal LED lights up purple when the power is on. Dirty air is drawn in from the air inlets on both sides of the main unit and decomposed by the photocatalytic filter. ・MY AIR uses Kaltec's unique photocatalytic technology to decompose and purify air pollutants, harmful substances, and viruses in the air, creating clean air.
