The Bosch 35 H AFC is also certified for dust class H compared to the Bosch 35 M AFC. Dust class H includes dust from all materials that cause cancer and other diseases (asbestos, etc.), and therefore the H model has increased user protection compared to the M model.

The GAS 35 H AFC Professional is the powerful wet/dry vacuum cleaner with increased user protection. Its safety filter captures 99.995 % of harmful dust. The certification for dust class H increases health protection against cancer and other disease-causing dusts as well as organic material (e.g. mould) and container building material (e.g. glass fibre).
