1. According to the cleanliness of the environment, the coarse filter cloth (polyester non-woven fabric) can be removed and cleaned or replaced regularly (usually 2-3 months).
2. Regularly (usually one week) sterilize the surrounding environment, and often use gauze dipped in organic solvents such as alcohol or acetone to wipe the surface of the UV sterilization lamp clean, keeping the surface clean, otherwise it will affect the sterilization effect.
3. Measure the average wind speed in the working area with an anemometer every two months. If it is found that it does not meet the technical standards, adjust the voltage regulator handle and change the input voltage of the fan to keep the workbench in good condition. When increasing the fan voltage is no longer sufficient to achieve a wind speed of 0.32m/s, the air filter must be replaced.
