You need a vapour and particulate combination filter for airbrushing, either 1 part or clip together.
When I was testing my 3M mask I had an A2 (US approx 3m 6001) organic vapour filter which had a clip on P3 (US P100) filter, but I can't find a US equivalent of the replaceable clip on P100, only P95. P95 isn't suitable for cadmium dust which is in several red paints.
Pic related is similar but isn't to the same level of protection.
The closest all in one seems to be 3M 60926.
The 3M 2091 would be fine for sanding alone.
