Cutting timber with the CleanSpace mask

I used my CleanSpace for several hours on the farm on the weekend when I was cutting firewood in combination with my chainsaw helmet with its built in visor and ear muffs. The wood dust and wood chips from the chainsaw go everywhere and get well and truly up my nose and into my mouth. But with the CleanSpace I felt completely protected and whereas usually I'm "blowing" crap out of my nose for hours afterwards ... nothing! It's a great tool for woodcutting and as I'm finding, doing many jobs on the farm.
