M1 NEOPRENE MASK
The M1 Neoprene Mask is made from the same material that’s used for wetsuits – making it comfortable, durable, and perfect for adding comfort in cooler temperatures. It features a single strap hook-and-loop closure, for easy on and off.
ACTIVE CARBON FILTERS
Each mask comes with two F1 Standard Filters that filter up to 99.9% of particulates down to .1 micron. The active carbon layer helps reduce odors and fumes. In high dust environments, change your filter every 10-20 hours of use. In lighter dust, filters may last up to 60+ hours.
