Infoseepage@SecurityWriter I'm a big fan of the Drager X-Plore 1950 and 1950v. It's a three panel mask like the 3M Aura, only more generously size. Very good breathing resistance due to the high surface area. Very good nose foam. One of the best sealing N95 mask's I've found and the straps are very adjustable/comfortable. Very well built mask with a high reusability factor. They test very high on filtration (above 99.8% on the N95 test).
