Please note that if you need reassurance regarding the certification of our products, we are willing to send you the copies of the relevant documents upon request! Splash resistance The unique feature of Type II R surgical masks is the liquid-repellent layer offering additional protection against particulate matter and infectious splashes. The greater protective efficiency of the masks adequately makes up for the higher breathing resistance (49 Pa/cm2). Disposable In order for your Type II R mask to effectively protect you from the pollutants you should wear it for a maximum of four to five hours. Please do not share your 3-ply face mask with other people. If your mask becomes damaged or dirty, throw it away. Please follow the World Health Organisation's (WHO) guidelines for correctly putting the mask on and off.
