If you mean the DIY dust-masks with a knob on the front, that's a valve
not a filter. They do reduce condensation, and prevent the wearer
touching their mouth and nose.
Inward filtering (their original purpose) is to FFP2, and people will
argue until the cows come home whether that stops infected droplets
only, or also the semi-mythical naked viruses themselves.
Outbound they'll stop the worst of a sneeze or cough.
