Half-mask respirator is an economical option with many of the same features found in premium masks. A wide, contoured sealing area provides a great fit that's perfect for extended wear. The low "dead air" space limits re-breathing exhaled air to increase comfort and worker productivity. Latex-free straps stretch and move with the worker while providing optimum support. Filters are limited to one 8-hour day of use. Half-mask respirator is designed for use in agriculture, foodservice, government and municipal service industries.
