Several years ago, I bought a decent-ish respirator from a BM (can't recall which one.) It's a twin filter, nose & mouth job with exhaust valve, twin straps & uses screw-in filters about 6cm across & 3cm deep. I bought dust & vapour filters to use as appropriate.
But ... I can't seem to buy the filters any more. It was quite expensive, so I don't really want to buy another one. Anyone got any good ideas where I can get these (the original BM doesn't even sell the respirators any more)?
Or, failing that, respirator recommendations sought.
