The 3M™ Half Mask Respirator Combo Pack: 3M7500P consists of a 3M™ 7500 series respirator in either small, medium or large, plus a pair of 3M™ 60929s mercury vapor cartridges with particulate filters and 100 alcohol-free cleaning wipes.
WHEN SELECTING RESPIRATOR STYLES & SIZES
As respirator styles increase in cost, they offer more comfort, ease of use and overall features. Most men will wear large, as the larger the respirator one can fit into properly, the more comfort. Most women wear medium. Small sizes usually work for people with a very short distance from the bridge of the nose to the bottom of the chin.
