What the specification says

FFP3 filter class, exhalation valve, ten per pack. Part number M632.

FFP2 or FFP3 — the number is the whole decision

FFP2 filters about 94% of airborne particles; FFP3 about 99%. Both are comfortable, both are cheap, and only one of them is the right answer for hardwood dust, which the IARC classifies as a Group 1 carcinogen.

The harmful fraction is the part that stays airborne for hours after the machine stops — long after the visible chips have settled and long after most people have taken the mask off.

The fit matters as much as the class

An FFP3 mask that leaks around the nose is an expensive FFP0. Pinch the nose bridge to the shape of your face, and check by breathing in sharply — the mask should pull against your face rather than let air in around the edge. A beard prevents a seal entirely, which is a real limitation and not a small one.

What comes up most often

Is a valve a good thing?

For you, yes: exhaled air leaves through the valve instead of fogging your glasses and heating the mask, which is the main reason masks get taken off early. For anyone else in the room, no — unfiltered breath goes straight out. In a one-person workshop it is the right choice.

How long does a mask last?

Until breathing through it becomes noticeably harder, or it stops sealing to your face — whichever comes first. A loaded filter is a working filter; a mask that has lost its seal filters nothing at all, whatever its class.
