3M Aura 9330+ is the most comfortable. The shipping from the Face Mask Store [0] is affordable and fast. They have many other FFP3 alternatives. With my last order, I got Dräger X-plore 1930 FFP3, which seems great, but I haven't tried it yet. FFP3 masks are not cheap, but high-end 3M disposable masks have a great fit, they are very comfortable, and you can wear them for days.
Thank you. I used the 3M FFP3 in Europe and they were quite comfortable but importing them is a bit expensive in addition to the mask itself (I don't reuse if I wear the mask for more than 6 hours). I keep a small stock for wave peaks but otherwise stay on 3M Aura N95.
