Abstract
A half-mask respirator is retained on a wearer's head by upper and lower straps and a strap support. The upper and lower straps connect to the strap support at upper and lower strap attachment points on each side of the strap support. The distances between the attachment points on each opposing side of the strap support are fixed when the strap support is located on the wearer's skull and the half-mask respirator is mounted over the wearer's nose and mouth. As a result, the lower strap is supported above the neck of the wearer which eliminates a potential source of discomfort for the wearer.
