A vacuum with proper HEPA filtration will channel nearly all (over 90 per cent) with the soiled airstream in the filter; if it doesn't make this happen, It really is basically rearranging the Grime. HEPA filters obstruct the airstream in vacuum cleaners: it requires Quite a bit of suction to tug air previous all those convoluted fibers. That's why vacuums with legitimate HEPA filtration have to have much more effective motors and types with small electricity might not clean efficiently.
