In some embodiments, the facemask has a front clip component that enables inserting elastic tubing/strap adjustably below the nose or looped back and then also inserted below the mouth to create ear loops. In addition, the external front clip—pressing between the filter and the interior back frame—allows for the vertical adjustment of the strap/tubing to customize/optimize the facial seal.In addition, the front clip can be externally disconnected and internally inserted to create a strap holding method or a strap clip can be inserted to also hold within the facemask the straps that would otherwise be loose.
