For example, when using Wanjiakang disinfectant, it can be configured to use a disinfectant with a concentration of 100-150ppm, etc., and then soak the filter into the disinfectant. - 2 hours, after 2 hours, rinse with water until there is no residual disinfectant.
When steam is used, it can be sterilized by saturated steam at a pressure of 0.1-0.15 mpa for 20-30 minutes. However, it should be noted that the steam valve should be slowly opened to prevent the steam from suddenly entering and damaging the filter element.
