The replacement time and service cycle of high-efficiency filters should be determined based on the actual usage environment. For example, for high-efficiency filters installed in cleanrooms, accurate data statistics on operating time and exhaust air volume are required. This is a reliable basis for the replacement time of high-efficiency filters. Under normal operating conditions, the service life of high-efficiency filters is more than one year. If the high-efficiency filters can be maintained and serviced reasonably, So the service life of high-efficiency filters can reach more than 2 years, and of course, it also needs to be determined based on the quality of the air filter.
The initial efficiency filter is usually replaced every 3 months, while the intermediate efficiency filter is usually replaced every 6 months, so the service life of the high-efficiency filter is generally around 24 months. Of course, in use, the application range cannot be arbitrarily increased. If the design and installation are unreasonable, the fresh air system treatment is not perfect, and the cleanroom control plan is unreasonable, it will also shorten the service life of the high-efficiency filter. In this case, the replacement cycle of the high-efficiency filter will also be shortened.
The common method to extend the service life of high-efficiency filters is to block dust at the middle efficiency filter. Efficient air filters are widely used as the main filter in clean rooms, commercial and industrial general air conditioning systems, as well as in ventilation and air conditioning systems with limited installation space.
