about pedometer

Hello, I would like to ask you, why can the triaxial gravity component in the pedometer still be filtered out by a low-pass filter? I think the components of gravity on the triaxials are uncertain, and it is debatable whether they can be filtered out using a low-pass filter. Can you give a more comprehensive explanation?
