Dual-mode head harness drops down when not in use

The 3M 7500 Series Half-Mask Respirator is more comfortable and durable than the 7000 Series Respirator. The unique head harness design adjusts easily so you have the option of wearing the respirator in traditional (when in use) or drop-down mode (when not in use). NIOSH approved. Available sizes: S (for very petite adults, children), M (fits 80% of population), L (people with large head/facial features). These are guidelines to assist with your sizing decision. There is no easy way to spell out the sizing on these respirators. Size medium will fit a majority of men and women. Once you receive your respirator, make sure it fits properly and passes fit testing requirements before using.

  • Soft Yet Secure: Advanced silicone material provides a softer feel and helps reduce red marks around the nose
  • Cool Comfort: Cool Flow™ exhalation valve helps you breathe easier and reduces heat and moisture buildup
  • Anti-Fog Design: Exhaled air is directed straight down to reduce the chances of fogging when wearing face shields
  • Easy Identification: Sizes are color-coded for easy identification
