It looks pretty good. I would get a supply of cartridges and change them regularly, if you plan on using it a lot. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />

Here's some info on respirator filters:

Filter Class ...Filtering of Airborne Particles .....Oil Resistance
N95 ...............Filters at least 95%.....................No oil resistance
N99 ...............Filters at least 99%.....................No oil resistance
N100 .............Filters at least 99.97%.................No oil resistance
R95 ...............Filters at least 95%.....................Some oil resistance
P95 ................Filters at least 95%....................Strong oil resistance
P100 ..............Filters at least 99.97%................Strong oil resistance

I use the P100 in my shop to paint, strip paint, sand blast, grind, cut wood, etc. With it on, I can't smell anything - which is good. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

Getting a good seal is key - this is where most dust masks fail.
