Leave it at room temperature (20 degrees Celsius) for about 20 hours. It is effective for bacteria, slightly effective for viruses, and consumes 0.3 degrees of electricity every day, which is similar to ozone. It has the advantages of high efficiency, broad spectrum, green sterilization, no pollution and no dead angle. It can rapidly reduce oxygen, promote cell activation, improve blood circulation and metabolism, and prevent diseases. ) cheap, easy to install and replace. The use method is simple and convenient. Other functions not only effectively sterilize the air, but also have no disadvantages for indoor pollutants such as formaldehyde and benzene.
