About Our Mask
Our masks comply with YY / T 0969-2013 standards. Important technical indicators include non-oily particle filtration efficiency and airflow resistance. The specific indicators are as follows:
❤Filtration efficiency: Under the condition of air flow rate (85 ± 2) L / min, the filtration efficiency for aerodynamic median diameter (0.24 ± 0.06) μm sodium chloride aerosol is not less than 95%, which is in line with N95 ( Or FFP2) and above. Can block airborne infection factors <5μm in diameter or close contact with droplet-borne infection factors.
❤ Inspiratory resistance: Under the above flow conditions, the inspiratory resistance does not exceed 343.2Pa (35mmH2O).
❤ The sample sprayed to the mask under the pressure of 10.9Kpa (80mmHg) should not have any technical indicators such as penetration inside the mask.
❤The mask must be equipped with a nose clip. The nose clip is made of a flexible plastic material with a length of> 8.5cm.
❤ The synthetic blood is sprayed on the mask sample at a pressure of 10.7kPa (80mmHg), and the inside of the mask should not penetrate.
