The amount of the air volume is determined by the size of the fan and motor. The amount of resistance caused by the filter also plays a role. The size of the inlet and outlet also come into the equation. A large fan will move more air than a small fan. A dense filter may trap more particles. However it will reduce the volume of air.

Mar 31, 2020 A pi filter is a type of LC filter, where the LC filters are arranged to resemble the Greek letter “pi.”. A pi filter can be configured as a high pass filter or a low pass filter. As these filters include three L or C elements, these filters are 3rd order in nature and provide strong rolloff above the cutoff (~20 dB/decade).
