Paper masks: mostly used in the food processing industry to ensure cleanliness and hygiene in the production process, but they have no filtering function, are easily wet and broken, and are not durable.

Absorbent cotton gauze mask: Commonly used masks are generally made of absorbent cotton gauze folded into several layers and then sewn together. Some are also made of non-woven fabrics. Generally speaking, a 3-layer gauze mask can only block 70%-80% of bacteria, while a 6-layer gauze mask can block more than 90% of bacteria. Usually, a 6- to 8-layer gauze mask does not feel too stuffy when worn. Since the SARS virus is mainly transmitted through close contact and droplets and is highly toxic, it is generally recommended to use a 12-layer to 16-layer gauze mask.

Three-layer surgical mask: The middle layer of filter can block particles larger than 5 microns (one millionth of a meter), has good ventilation, is comfortable to wear, and is easy to use. It comes in ear-hook type and strap type.

Activated carbon mask: a functional mask specially designed for virus protection, with good disinfection, sterilization, deodorization and dust prevention functions. The built-in wire bends according to the face shape, effectively closing the gaps on both sides of the nose and creating a good breathing space for the mouth and nose.

Bamboo charcoal mask: Bamboo charcoal mask, with small charcoal particles made from bamboo burned at ultra-high temperatures sandwiched in the mask, fully utilizes the dehumidification and super adsorption effects of bamboo charcoal. The negative ions generated purify the air and play a special role in filtering out harmful substances and germs. Bamboo charcoal masks are popular overseas.
