Smart FFP3 filtering masks that offer maximum protection combined with exceptional respiratory comfort. The Narvalo Active Shield valve, integrated into this mask, makes it superior as it provides breathability performance significantly above average. This valve features an adaptive fan that reduces heat and humidity while extracting CO2, ensuring maximum freshness during use.

Thanks to the pressure sensor, the Narvalo Active Shield adjusts the fan’s speed based on the user’s breathing rate, maintaining consistent respiratory comfort even during strenuous activities.

Lithium Battery: The battery (800 mAh) offers up to 8 hours of autonomy and is easily rechargeable through the micro USB charging port located on the side of the device. It is available in versions with and without activated carbon (C).
