Some of these filters have the PM * marking going right the way through the filter and there are holes which means they don’t filter anything at that point! The manufacturer should find a way to make the marking with ink rather than using the thermal sealing for the edges to make the marking. Fortunately, it’s nowhere near the nose location but still, it’s a weakness in the filtering ...
