I tend to use a Scott half mask with particulate and vapour protection, it's probably overkill for the airbrush but when using the spraycans it does help (having said that our graphicair spraybooth is strong enough it's generally not bad even without).
I suspect your other half should be ok across the room with airbrushing if you've got the extractor running
IIRC you can get facemasks fairly cheaply with replaceable filter carts, the Scott ones are about £15 for the mask then £15 for the filters, in theory with the vapour protection filters you're meant to change them every 6 months.
Cheers for this.
I was thinking of getting a 3M mask with replaceable filters. I'll use the airbrush and booth really infrequently (I paint models for fun, rather than armies so I tend to pick something up once every month or two), so I'm sure sealing the mask in a tub will give me months of use. I was more concerned for the other half as I don't want to unfairly risk her wellbeing.
I have it all in my cart now and just deciding if the near £300 bill is worth it or not!
