Peter, respirators that have carbon filters are designed specifically for fumes and gases and are complete overkill if you only want to protect against dust.
You also don't need to have any of those two fully enclosed systems you have tested above. Those are meant for professional spray painters who work in a spray booth for 8 hours a day. Or other people working with chemicals.
For occasional use like painting a mask that only encloses your nose and mouth is good enough. I have one by 3M similar like this one which costs 35 euros. It works great and you don't smell anything besides the plastic of the mask itself.

Jesse Cloud said:Good advice above and I would like to emphasize Alex's point about smelling. If you can smell it, then you are breathing it.
In addition to the effectiveness of the filters, a good fit is crucial. Some masks fit particular faces better than others.
I was lucky enough to be fitted for a respirator by a plutonium chemist from Los Alamos. He spent about 15 minutes fiddling with the fit and I used a magic marker to mark all the strap adjustments so I could replicate what he came up with.

The N95 is for particular matter, dust.
OV is for organic vapors.
AG is for acid gases.
AM is for ammonia.
FM is for formaldehyde.
HG is for mercury.
I would be looking at the OV series for the 3M filters.
The danger for the volatile compounds is not only fainting but also the damage the chemicals can cause to various organs. Some can cause brain damage, lung damage, or liver damage.
