A face mask to be worn over a user's face, the face mask comprising:
- two ear straps, each configured to be worn around a corresponding ear of the user, each ear strap comprising a connector support element,
- wherein each of the connector support elements comprises an ear base portion comprising a top end, a bottom end, a hollow cavity having a longitudinal length extending from the top end to the bottom end and a locking element protruding perpendicularly outward from a surface of the ear base portion, the hollow cavity configured to allow each ear strap to extend through the hollow cavity,
- wherein each of the ear base portions of the connector support elements is movable along a fixed length of each ear strap for adjusting a location of each of the connector support elements along the fixed length of each ear strap,
- wherein the face mask comprises a head strap, and the connector support elements are configured for removable attachment of the head strap, thereby allowing the face mask to be worn in two configurations, wherein:
- in a first configuration, the face mask is configured to be supported on the user's face by the ear straps that are worn around the user's ears, and
- in a second configuration, the head strap is removably attached to the ear straps via the connector support elements, such that the face mask is configured to be supported on the user's face by the head strap, and
- wherein the head strap comprises a receiving element at each free end and is removably attachable to the ear straps via insertion of each locking element into an aperture of the respective receiving elements at each free end of the head strap, wherein each receiving element is a snap joint, and
- wherein a direction of the insertion is transverse to the longitudinal length of the hollow cavity, posteriorly towards a rear of the user's head when the head strap is worn.

A method of wearing a face mask having a head strap and ear straps attached via free ends on each side of the face mask, each ear strap comprising a connector support element to allow removable attachment of the head strap, the method comprising the following steps:
- in a first configuration, supporting the face mask on a user's face by the ear straps such that the ear straps are worn around the user's ears, wherein each connector support element comprises an ear base portion comprising a top end, a bottom end, a hollow cavity having a longitudinal length extending from the top end to the bottom end and a thickness, and a locking element protruding perpendicularly outward from a surface of the ear base portion, the hollow cavity configured to allow each ear strap to extend through the hollow cavity, and
- in a second configuration, removably attaching the head strap to each ear strap via the connector support elements, such that the face mask is supported by the head strap,
- wherein the head strap comprises a receiving element at each free end and is removably attachable to the ear straps via insertion of each locking element of the ear strap into an aperture of the respective receiving elements at each free end of the head strap, wherein each receiving element is a snap joint, and
- wherein each of the ear base portions of the connector support elements is movable along a fixed length of each ear strap for adjusting a location of each of the connector support elements along the fixed length of each ear strap, and
- wherein a direction of the insertion is transverse to the longitudinal length of the hollow cavity, posteriorly towards a rear of the user's head when the head strap is worn.
