I have one FFP1 mask and it has a valve. A number of years ago, I picked up a couple of boxes of N95 masks. The FFP1 mask is CE marked and the N95 masks are US made and not CE marked. This particular N95 mask doesn't have the exhale valve and is what we wear if/when we go out and about.
The interesting thing that I learned about the N95 masks is that apparently they all incorporate an electrostatically charged layer which permits particulate capture without impacting respiration.
We reuse the masks but isolate them for several weeks between uses.
