The disposable medical mask is suitable for covering the mouth, nose and jaw of the user, and is used in a general medical environment to wear, block the oral cavity and nasal cavity to exhale or spray contaminants. The bacterial filtration efficiency of the mask should not be less than 95%. Not applicable to medical protective masks and medical Surgical Masks.

The ventilation resistance of the gas exchange on both sides of the mask should be no more than 49Pa/cm³.
The ventilation resistance test takes the center part of the mask for testing. The gas flow for the test needs to be adjusted to (8±0.2) L/min, the diameter of the sample test area is 25 mm, and the test area of the test sample is A. Measure the pressure difference between the two sides of the mask with a differential pressure meter or equivalent equipment, and calculate the ventilation resistance according to the formula ΔP=M/A.
ΔP-the pressure difference per square centimeter area of the test sample, the unit is Pa per square centimeter (Pa/cm³);
M --The differential pressure value of the test sample in Pa (Pa);
A --Test area of test sample, unit is square centimeter.
