-An oxygen mask is a crucial piece of safety equipment designed to provide a steady flow of oxygen in environments with low oxygen levels or high levels of pollutants.

-These masks are commonly used in aviation, medical settings, and emergency situations. 

-They come in two sizes to accommodate different face shapes and are made from durable materials that can withstand harsh conditions. With adjustable straps and a secure seal around the nose and mouth, oxygen masks ensure a proper fit and prevent leakage.

-They are equipped with a transparent plastic visor or cup that covers the nose and mouth, allowing for clear visibility while breathing. 

-Some models also feature filters to remove harmful particles from the air. Whether for pilots, patients, or rescue workers, oxygen masks are essential for maintaining proper oxygen levels and ensuring safety in critical environments.
