Get effective, easy-to-use and fully-assembled breathing protection with 3M™ Maintenance Free Reusable Respirators 4000+. A newly enhanced valve assembly helps to reduce exhalation breathing resistance for improved breathing comfort.

An adjustable head cradle helps fit to a broad range of head shapes and sizes, and the neck straps are easy to fasten. The low-profile design won’t hinder your peripheral vision, and the two large, bonded-carbon filters provide low breathing resistance. Available in a choice of four models.
