I have a single stage Jet dust collector with the quilted thing on top for filtration. But every time I clean the unit or change the bag or notice that the bag is not filling up like it should I find that all the debris packed into the top filter and yes I do rotate the thing inside every time I use the unit and beat the sides of the upper filter etc and the dust still goes up and stays there.
Any suggestions as to what am I doing wrong or is this just the nature of single stage dust collection?
