Results: impact on airflow, pressure and noise
After analyzing the nylon and plastic dust filter, we now add a test of the “foam” dust filter. The latter has a slightly more complex construction. It consists of several parts and is kind of like a jigsaw puzzle, the elements of which even improve the aerodynamics in some ways. We go through everything in detail, and although we approached this type of filter with a bit of a bias, it comes out in a good light in the end. Is a foam dust filter better than a nylon one?
