1. Case: Keeping the case clean can reduce the source of indoor air pollution. Regularly wipe and clean the surface of the cabinet. When contamination occurs, clean and disinfect at any time. Pay special attention to the air inlet and outlet when cleaning.

    2. Filter: The cleanliness of the filter is related to the frequency of use of the sterilizer and the air quality. In the case of high frequency and poor indoor and outdoor air quality, the filter is more likely to accumulate dust and dust. Therefore, the filter should be checked regularly Net, find dust, rinse with clean water or neutral detergent in time, replace the filter when it is damaged and aging. When it is suspected that the place of use is more polluted, the inspection frequency should be increased.

   3. High-intensity ultraviolet lamp: The filter at the air outlet of the sterilizer can protect the ultraviolet lamp. The circulating air entering and exiting the machine is relatively clean. Therefore, cleaning the filter is much more important than wiping the tube. If the lamp is found to be dusty, wipe it with 75% alcohol to ensure that the radiation intensity of the lamp is not affected by the dust. The intensity of ultraviolet radiation is the key to killing bacteria. Therefore, the radiation intensity of ultraviolet lamps in the machine should be monitored every six months. When the radiation intensity is less than 6000uw / cm2, the lamps should be replaced in time to ensure the disinfection effect.
