This mask is the same as the 8210, with the addition of a one-way exhalation valve for enhanced airflow, comfort, and heat dissipation
The 8210-V "respirator" dust mask is designed to help provide quality, reliable protection against certain particles generated during sanding, sweeping, or other dusty operations.
• A thin, lightweight mask with a smooth, firm lining
• Exhalation valve makes it easier to breathe through and keeps you cooler
• Lightweight, comfortable
• No faceseal, but adjustable noseclip helps provide a close fit, and prevent eyewear from fogging
• Advanced Electret Media enables the respirator to attract particles without sacrificing breathability
• NIOSH approved N95 particulate respirator - provides 95% filtering efficiency
• Priced by box of 10
Note: According to the CDC website (8/7/20), because the direct-vented exhalation valve on this mask releases unfiltered air when the wearer breathes out, this mask doesn't adequately prevent the wearer from spreading Coronavirus.
