Measurements and calculations of plasma temperature and density in the discharge area proved that the plasma electrostatic adsorption device can effectively destroy all pathogens in the air. The charge leakage index of each monitoring point was less than 0.5, within the measurement error range, proving no plasma charge leakage was detected.

YD1 has a simple control system with clear display of unit settings. The unit can be operated by pressing buttons. The timer button can set the running time- 2h, 4h, 8h and cycles setting. The air speed button can set the air speed - low, medium, high mode and Auto operation mode.

The multiple air purification and disinfection technologies efficiently provide clean air. Washable metal pre-filter and electronic cell can be cleaned and reused to reduce replacement cost.

YD1 is equipped with two UV lamps and photo catalytic filters. UV light destroys all microorganisms, and its irradiation on photo catalytic filters generates strong oxidizing free radicals that decompose harmful pollutants in the air.
