The P370 features a 5-stage air purification system. The five stages include a pre-filter for large dust particles and hair, a HEPA filter with H13 filter material for fine dust, smoke, and allergens, an ionizer to enhance filter performance, a UV-C light to reduce certain viruses and bacteria, and a photocatalytic filter that reduces chemicals and odors. The P370 is also equipped with a particle sensor that displays air quality by changing the front light from blue to orange to red, depending on the air quality. The P370 can clean the air in either manual mode or automatic mode, adjusting its performance based on air quality.

The P370 can operate fully automatically, adjusting its cleaning performance according to the measured particle pollution in the air. In AUTO mode, the 5-stage purification can be utilized with maximum efficiency, reducing unnecessary energy consumption and noise. Additionally, the device displays the measured air quality, allowing the user to respond to high particle levels, even when the device is set to manual mode.

Five steps to capture as many pollutants as possible, and an air quality sensor to do this fully automatically.
