What is N95 MASK?

N95 respirators and surgical masks (face masks) are examples of personal protective equipment that are used to protect the wearer from airborne particles and from liquid contaminating the face. Centers for Disease Control and Prevention (CDC) National Institute for Occupational Safety and Health (NIOSH) and Occupational Safety and Health Administration (OSHA) also regulate N95 respirators.

It is important to recognize that the optimal way to prevent airborne transmission is to use a combination of interventions from across the hierarchy of controls, not just PPE alone.

What is the difference between valved mask and no valve?

The protective performance of valve mask is the same as no valve mask

Function of breathing valve: in hot and humid working environment with poor ventilation , breathing valve can help you feel more comfortable.

The function principle of the breathing valve is that.

Positive pressure is generated by exhaling, the valve plate is blown open, gas in the body is discharged rapidly, so the sense of stuffy heat is relieved.

When inhaling, the negative pressure will automatically close the valve to avoid inhaling pollutants from the external environment
