I brought this home from work - I think I used it once when I was putting insulation between my roof joists in my workshop prior to plaster boarding. I've tried looking up and I can’t find if 'P2R' is the same as 'FFP2'. I suppose it’s better than nothing but it is a lot easier to wear than other dust type masks as it has ventilation valves so the filter material doesn’t get wet with condensation from exhaled breath. If I put my hands over the side filters, it shuts off completely so it has a very good face seal. Any ideas whether it a good one?
