The main purpose of this work is to show the importance of used fluid quality in defining technological and constructive conception of aircraft, in other words to point out the importance of filter and filter equipment choice. Filters and filter equipment represent necessary parts of aircraft and primary role of these systems and filtration in general is passanger and the environment safety and reliability and efficiency of aircraft . The correct choice of filters and filter devices, the sufficient number of filtration steps and the efficient filtration on each position cause the reduction of exploitation costs, the aircraft optimization as well as the achieving first-rate performances.The choice of filter and filter systems represents one of the most important steps in defining technological and constructive conception of aircraft in which the quality of used fluid is especially relevant. Shortly, filter systems of aircraft represent vital parts which, beside the role of providing qualitative, reliable and efficient filtration, protect people and the environment. Filter systems that are characteristic for helicopters and their flights on particular and specific regimes are presented in the work. Special attention is also drawn to cabin filters in travel aircrafts. It is stated that it exists the need for sufficiently effective filtration of the cabin air in order to control the air contamination and provide comfort and feeling of healthy environment to both passangers and crew. Without the effective filtration of cabin air, the infection risk is very high. In the end of the work some of the tests that are being carried out in persuance of more rapid and efficient control of aircraft filters are shown.
