Hygiene face mask is divided into medical and non-medical mask, and the standards of each country are different. The face mask can be roughly divided into children face mask, KN95 face mask, N95 face mask, FFP2 face mask, FFP3 face mask, etc. The mouth mask selected by our company must first have a complete production qualification. The raw materials and production process must be strictly controlled. For different markets, we choose products with different certificates such as CE and FDA. Our company has a long-term cooperative relationship with major face mask manufacturer, which allows us to obtain very good purchase prices. We have cooperated with more than 100 wholesale face mask suppliers.
Masks for the prevention of the new crown virus should be medical grade face masks or N95 masks, which have a good filtering effect on the new crownvirus. Medical-grade masks can basically filter 0.24 micron particles. N95 masks are more effective, and have good protection against particles above 0.075. No matter whether it is a virus or a bacteria, it generally does not exist alone, and is basically carried with droplets or aerosols in the air. Aerosolsand droplets are generally about 5 microns in diameter. Medical-grade masks can be effectively protected, while best disposable dust mask cannot.
When choosing a standard mask, if it is a temporary outdoor work, you can choose ordinary cotton masks to keep warm. If the air pollution is serious, such as haze and other weather, you need to choose PM2.5 masks, such as N95 disposable mask, which can be used for disease protection. Medical protective masks can play a certain role in preventing influenza.
Ordinary disposable dust mask can prevent some dust, but the effect is average and cannot prevent diseases.
Regardless of whether it is a disposable face mask or a medical mask, there are actually front and back sides. Take a disposable respirator for example, the darker color is the front side, and the front side should face outward, and there are metal strips on the nose clip on the medical mask.
The face facing the face should be the reverse side of the medical mask, that is, the lighter side. In addition, it should be noted that the part with the metal strip should be on the top of the mask. Don't wear it backwards.
After distinguishing the front, back, upper and lower ends of the disposable mouth mask, wash your hands first, and after confirming whether the face mask levels are correct, hang the elastic cord for masks at both ends on your ears.
After wearing the Chinese mask, you need to press the metal strips on both sides of the bridge of the nose with both hands to make the upper end of the mask close to the bridge of the nose, and then stretch the mask downwards so that the mask does not leave any wrinkles, and it is best to cover the nose and mouth.
This depends on which mask is used. Most antiviral mask is for one-time use and cannot be reused. Unless it is a reusable flu mask.
