Personally, I found P95 or N95 particulate combined with organic vapor to work well. I can't smell any of the particles or fumes from what I'm working. If you use the particulate filters alone, you can still notice the phenolic fumes and stuff when working with Micarta. It might be bad for you, it might not be, either way, it stinks, so I use a combination cartridge which does vapor and particles.
You could use a P100 particulate combined with organic vapor cartrdge if you wanted to be extra extra safe, but I'm not sure that it really makes a difference.
That's how I dress when I'm working. Most people say I'm too safety conscious, but I like being safe.
I wear a 3M 6000 series half mask respirator, which takes two cartridges on each side. Each cartridge that I use is a organic vapor cartridge, with a N95 prefilter fitted over it with a 3M 501 retainer piece. I replace the N95 filters fairly often, but haven't found the need to replace the vapor cartridge under it too much. Where your health is concerned though, I would not want to used an expired cartridge or filter.
Here is product number list for what I use:
3M 6200 Half Face Mask (or 6100, 6300, depending on what size your head is)
3M 2091 P100 Particulate Filter (for when particles are the only concern, and there are no fumes)
3M 6001 Organic Vapor Cartridge (should come in a little sealed paper carton or bag with 2 cartridges in them each)
3M 5N11 N95 Prefilter, put it over the 6001 cartridge. Get a decent amount of these as they get gunked up somewhat quickly, throw em out when they get used up.
3M 501 Retainer, get a couple of these, you have to have these in order to hold the prefilter down.
Make sure you have enough eye protection too. I usually wear goggles and a faceshield, or sometimes just the goggles for light work.
I'm thinking about adding some ear muffs instead of plugs. My head is getting pretty heavy with all the equipment though.
