Air filter is a product that captures and adsorbs dust particles or gases of different diameters in the air, so as to purify the air and improve the air quality. Air filters with different filter materials can be used in different places, such as biopharmaceuticals, hospitals, residential areas, office buildings, clean workshops, etc. Ordinary central air-conditioning and ventilation systems are generally equipped with primary air filter screen in the air handling unit, which can filter particles with large particle size. In places with higher requirements, secondary air filter will be installed behind the primary air filter.
The filter materials selected for purifying particulate pollutants can refer to the following table

    Refer to the following table for the filter media that can be selected for purifying gaseous pollutants:

    Industrial primary filters, medium efficiency filters, bag filters, high efficiency filters, chemical filters, etc. produced by Shanghai Junkai Environmental Engineering Co., Ltd. have been used in many industrial fields such as automobile manufacturing, industrial coating equipment, electronics, pharmacy, photovoltaic, food hygiene, scientific research institutes, etc. According to the requirements of the industry, practical air filters are generally used in combination, which can prolong the service life of medium efficiency filters or high efficiency filters and save costs.
