When it comes to protecting your health, price should be a consideration but not the only criteria. After 40 years in the Fire Service it is just now coming to light that Fire Fighters have a 68% chance of getting some sort of cancer! A lot of that is due to inhalation hazards. That being said, I prefer the half face respirators over the N95 dust masks. Mostly because they are available in a variety of sizes to better fit the face. I also echo the comments on eye, feet, hand and hearing protection.
