M2.5 MESH MASK
The M2.5 mesh mask features highly breathable mesh fabric construction that helps to keep you cool on even the hottest summer days. The M2.5 mask opts for a flexible dual elastic strap system with quick-release buckles. This adds an extra touch of security and comfort, making it ideal for exercise and movement, or when you must wear your mask for an extended time.
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.
