Masks are good in certain areas like:

- Healthcare settings: to prevent the spread of infections and diseases
- Industrial settings: to protect workers from hazardous materials and particles
- Crowded public places: to reduce the transmission of airborne pathogens, like during pandemics
- Outdoor activities: like hiking, biking, or gardening, to protect from dust, pollen, and other allergens
- Artistic applications: like painting, sculpting, or woodworking, to prevent inhalation of harmful materials
- Sports and fitness: like wrestling, boxing, or gymnastics, to protect the face and head from impact.
