The different styles are designe for different users and different types of dust or vapour you need to filter out.

FFP 1 is low efficiency and only for larger particle size.
FFP 2 is a better option and filters small down to PM2.5
FFP 3 is a better option again and will filter out down to PM 10 and take out some vapours.

That's how I understand it and. I would recommend the FFP2 for wood turning, the FFP1 will do for most woods and activities but the FFP2 is a good general "cover most" filter.

Just seen grandads reply.. The one linked is a "cover all" if that's what you prefer then go for cover all.
