DR Professional Protective Mask - KN95 Protection Level - is designed to filter out solid particles such as pollen and bacteria, providing protection against these types of airborne particles. It is important to note that this mask is not intended as a substitute for industrial anti-fog masks and should not be used to protect against toxic gases or chemical fumes. The mask can be washed with water or alcohol and reused. It features a Five-Layer filter layer that effectively filters harmful substances and meets the national KN95 standard. DR Instruments offers a wide range of Personal Protective Equipment, including Medical Gloves, Medical Masks, Thermometers,  and Lab Coats.

The design is based on the three-dimensional shape of the face to ensure the tightness of the mask, increasing the breathing capacity of the mask, significantly improving breathability, and making wearing and breathing more comfortable. 

This is a Non-medical device.
