Srekar,

I don't have the original bag that it came in, but I do use the 3M Organic Vapor respirator that I got from my local Auto Color paint store. They have two versions one that is disposable for about $20 and one with replaceable cartridges for about $30, the replacement cartridges are about 8 bucks. The only number on the mask is 6001. But it is labeled as the "3M Organic Vapor" they sell the same exact mask at home depot or lowes but it was almost 10 bucks cheaper at the professional auto paint store.

These masks only provide the minimum protection. If you are painting inside you need plenty of circulation, an exhaust fan to keep pulling the overspray out is needed. You will be standing in a cloud of paint without it. Also get the full on paint suite, with hood and booties (less than 10 bucks at the paint store), I also where latex gloves when I paint. goggles are a good ideal as this paint effects your eyes too.

The hvlp guns minimize overspray and your exposure.
