4 Additional Valves


3 Additional Replacement Valves for Mask.

ACTIVATED CARBON FILTER: The carbon filter is designed to filter out at least 95% of particles that are larger than 0.3 microns in diameter. The filter is made of five layers of non-woven and activated charcoal microfiber.

BREATHING VALUES: Using an N95 mask with an expiratory valve allows you to exhale more easily and helps reduce heat accumulation.

When inhaling, the mouth cover will be closed to ensure that no particles enter. As you exhale, the cap opens and lets the moist, hot air out. At the same time, there is a soft mouth cover inside, which helps to keep out small particles.

EASY BREATHING AND REDUCE OVERHEATING: The two dual one-way exhalation valves prevent fogging and overheating exceptionally well.
