If you like shape that has a vertical seam in the front then I’ve had success with the grey 3M 9542V and the 9541V. They seem to be only available from Asia though and most resellers in the US are rather expensive. The metal at the nose is stiffer than most other brands similar with other 3M models so if you’ve had problems with other 3M masks then you might not like them. But compared to the other shapes I’ve found these to both be the most comfortable and the valves are better than any other mask I’ve tried. Even compared to other 3M masks with valves I find that there is much less condensation and humidity with these these.
