According to the inquiry, the sterilization rate is as high as 99.99%. PST+ ultra-electromagnetic ionization odor purification technology "aims to eliminate odor within 19 minutes when the odor reaches its peak. The air inside the refrigerator is continuously sucked into the super-magnetic induction discharge field through the vortex suction chamber, and the electric field will release a large number of active ions, which has the ability to absorb and decompose odor molecules.
