The P300 features a 5-stage air purification system. The five stages are (1) a pre-filter for large dust particles and hair, (2) a HEPA filter with H13 filter material for fine dust, smoke, and allergens, (3) an ionizer to enhance filter performance, (4) a UV-C light to reduce certain viruses and bacteria, and (5) a photocatalytic filter that reduces chemicals and odors. The P300 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 P300 cleans the air either in manual mode or in automatic mode, where it adjusts its performance based on air quality.

The P300 can operate fully automatically and adjust its cleaning performance according to the measured particle pollution in the air. In AUTO mode, the 5-stage cleaning can be utilized with maximum efficiency, reducing unnecessary energy consumption and noise levels. 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.
