This is true.
I do a lot of spray painting in my job, we do have an air fed mask but it is rarely used due to it being restrictive for moving around the paint booth when going in & out for doing multiple parts.
Most of the time I just use a Moldex full face spray painting mask in work which gives a great field of vision, protection & isn't restrictive for movement at all. These are fairly expensive at around £70-£80 but offer a good level of protection especially for your eyes which some people overlook.
For spray painting at home though where I mainly use spray cans I just have a good single filter face mask & wear goggles at the same time. This mask was only around £20 from eBay so very affordable.
Definitely worth investing in a decent mask if you haven't already Dan.
