masks (ventilation masks)

Ventilation masks are devices worn over the face to deliver clean, breathable air or oxygen to the wearer. They come in various types, such as surgical masks, N95 respirators, or full-face shields, each designed for specific protection levels. Masks filter out harmful particles, bacteria, or viruses, helping to prevent infection or exposure. They also help contain respiratory droplets, reducing the spread of contagious illnesses. Proper fit and usage are crucial for effectiveness. Masks are essential in healthcare, industrial, or pollution-prone environments to safeguard respiratory health.
