Scope of application
Two-layer masks are primarily used in food processing plants. They consist of two layers of nonwoven fabric sewn together, with no meltblown filter layer in between. These masks are mainly designed to prevent substances from the mouth from entering food.
The three-layer mask features a meltblown filter fabric and is suitable for medical settings, outdoor use, dust-filled factories, and other environments.
Activated carbon masks are suitable for applications with stricter requirements for dust and bacteria.
Selection method
Make sure to follow the steps I’ve provided—appearance, texture, smell, and wear.
First glance: Check whether the face has a healthy glow and is free of stray hairs.
2. Touch: Touch the entire mask to see whether it feels soft, smooth, and not rough.
Three types of odors: When you smell it, is there an unusual odor? From the fabric surface to the ear hook, there is an unusual odor.
Four checks: Check whether your ears, the tip of your nose, and your face are itchy.
