Sale of protective respirators, masks, mouthpieces, antigen tests and other protective aids. Respirators are intended to protect the wearer from dangerous particles from the external environment. They are equipped with powerful filters that capture particles from ordinary dust to microorganisms, viruses or gases. Thanks to breathing through filters, they clean the inhaled (and often exhaled) air, which is why they are effective protection for the wearer. Their disadvantage is a higher price. Masks or mouthpieces are used to protect the environment from the spread of the virus from the wearer. If the wearer shows signs of a viral infection, the mask helps eliminate the spread of the virus to the surrounding area. It protects people in the vicinity, but only partially protects the wearer. Not tight enough around the face.
