Introducing M21® – the world’s first two-chambered mask design system utilizing its patent-pending Directional Airflow Technology™.
Traditional masks force wearers to continuously breathe in their own recirculated, exhaled air, which can interfere with airflow and restrict oxygen intake. M21®’s two-chamber design supports the natural breathing process by isolating the nose and mouth.
Maximum level of Comfort
Ideal for long-term wear
