Ingeniously simple and simply ingenious - the "IngeniaMask"
Since there is a small gap between the face and the mask, breathing is no more difficult with the mask than without. In contrast to a close-fitting mask, the exhaled (used) air can escape and oxygen-containing air can be inhaled again.
Since the mask is completely closed at the front, it protects other people against the exhaled air (aerosols) and also serves as protection against droplets for the wearer.
With normal breathing through the nose, the exhaled air is strongly slowed down and directed along the body.
Due to the special shape of the mask, the exhaled air can escape up and down. There is no contact pressure, so the air is deflected and stays with the person wearing the mask. This greatly reduces the spread of aerosols.
Not every plastic mouthguard / shield meets the requirements for a PPE - CommunityMask. With IngeniaMASK you are on the safe side. (Approval)
