This is not a medically certified product but an auxiliary mask to cover the area of your mouth and nose. The mask does not come with a filter included but an additional filter can be placed between the two layers of fabric.
This mask does not serve the purpose of self-protection but merely provides a certain level of protection towards third parties. Washing before first use is advised.
