Before upgrading to a cyclone I bought the shaker felt bags from
Highland Hardware. What a ripoff. After the first garbage can of
dust/shavings they get that magical cake of dust on the inside that they
claim helps filtration. What it really does is choke off the airflow.
I was getting around 500 CFM with a clean bag. That dropped off to
under 250CFM as soon as the bags got dirty.
The only bag upgrade worth doing is the oversized bags from a reputable
supplier. They need to be vastly oversized so they'll still flow enough
air when they get dirty.
