Fiber composite materials show more favorable filtration properties in terms of filtration efficiency and accuracy, as well as dust absorption. Experimental tests of standard filtration materials based on cellulose, polyester, glass microfiber, cotton and polyester nonwoven fabrics were performed using an original method. Two composite beds consisting of three layers of standard materials were designed using a novel method: K1 (polyester-glass-microfiber-cellulose) and K2 (cellulose-glass-microfiber-cellulose), and determined their effectiveness, the size of dust grains in the cleaned air and the unit dust absorption. It was shown that the K1 composite has high (dpmax = 1.5-3 μm) filtration accuracy, high initial filtration efficiency (99.8%), which shortens the preliminary stage, and extends to 96-98% the duration of the main stage of the filtration process. The K1 composite achieved more than twice the dust mass loading value (kdK1 = 148.9 g/m2), compared to other standard materials. These are parameters that are essential for filter design in automotive technology and can only be obtained through empirical testing. Knowing them will make it possible to make an air filter design with smaller dimensions or to extend vehicle mileage.
