I'm spraying acrylic rattle can in a garage but don't have a mask, I've tried looking at 3M guides but I'm none the wiser as to what cartridges to use, can anyone offer some pointers?
A particulate filter rated P2 and gas filter rated A1 would be OK for that application. After a bit of searching on that 3M link above I found that the filters are A2 and P2 so it should be fine for what you want. Price from Cromwell seems ok.
