Low Risk Dust Extractors - L-Class
L-Class dust is considered some of the least harmful and can be commonly found in the home. Everyday house and soil dust, for example, would fall under ‘L’. Therefore, there is a smaller long-term risk in you breathing this in, though you must still take precautions.
Class L extractors operate at 99% efficiency and therefore work to an occupational exposure limit of 1mg/m3.
