Abstract: A filtration device against breathing in of small particles or virus, comprising a filtering membrane for air filtration, at a distance to the face to create a large space of the filtered air and a large active area of the filtering membrane for easy breathing and for low resistance, which the filtering membrane puts up to the flowing of the filtered air, wherein, die space of the filtered air includes a free space under the nose and a free space under the chin flowing of the breathed out air directed through the nose around the chin to the neck. The breathed out air is discharged through an active area of the filtering membrane into the free space and/or the filtering membrane by moving away to a distance from the cheeks creates a large space in front of the cheeks of the face flowing of air to the sides and creates a large active area of the filtering membrane extending to the sides up to a few mm from the ears, wherein the large space of the filtered air in the space at the ears, is realized by an offset or by a step offset.

Abstract: Face coverings that protect the facial T-Zone region (i.e., eyes, nose, and mouth) from airborne transmission of infectious and other harmful particles are disclosed. The face coverings disclosed herein are designed to attach to the temples, frames, and/or the bridge of eyewear, which provides protection for the eyes of the wearer and dispenses of the need to adjust straps traditionally found on face masks. The face coverings may be converted to different configurations depending on the amount of protection and comfort desired by the wearer. For example, the face coverings disclosed herein can convert from a free-hanging position to a more protective configuration in which the mask conforms closely to the face of the wearer.
