In the composition of the air-conditioning system, the air filter is one of the components that have great importance for air quality and for the proper functioning of the system. In this work, we analyzed the air-conditioning system and air filtering mechanism and its chemical and physical solids retention compositions, which includes the powder in this condition, and compared thick air-conditioning filters that have Polymers in their composition. In view of the need to evaluate the efficiency according to some guidelines of NBR 161O1, air filters were developed with non-woven polyester, viscose and cellulose acetate which, in addition to seeking to comply with the standards NBR 16101 (2012) and 16401 (2008), are committed to reduce the space used by the filters in the companies, to reduce costs, to obtain information about partiele retention and to have less loss of load, when compared to the type of filter most used in the market. In the retention tests, the granular materiais of phyllite and talc were used because of their size characteristics and ability to penetrate the filters. It was also possible to have a lower price being around three times smaller compared to the conventional filter most used in the market. In contrast, the conventional filter most used for the air-conditioning system has greater particle retention and less loss of charge. Inside. Also developed filter samples more suitable to the equipment assembled for the load loss and particle retention tests.
