Breathe Easy with Bosch:

All Bosch orbital and random orbit sanders feature through-the-pad dust extraction to pull dust away from the work surface to maximize sanding efficiency and to extend paper and disc life. The revolutionary Bosch Microfilter system with its integrated paper filter, captures the highest volume of all size dust particles, providing reduced exposure to dust. The filtration system collects up to 120% more dust than other leading brands and traps dust particles as small as 1/2 micron. The durable canister is easy to empty and clean.
