If yuor blower is not working, your lucky. Who wants all that dust flying around your shop anyway? On both of my scrollsaws, my drill press, tablesaw, Band saw, joiner, etc. I have "Dust Collectors".
One good gauge for dust in the air is to look at your glasses. If you got dust on them you have dust going to your lungs and that ain't good. So quit blowing and start collecting.. If you want to see more I will try to post pictures.
