configurations) (all Filters except 3M™ 6035 /6038/ 2000
Series Filters).
Place palm of hand over exhalation valve cover and exhale

If the facepiece bulges slightly and no air leaks are detected
between the face and the facepiece, a proper seal has been
obtained.
If an air leak is detected, reposition the respirator on the face
and / or re-adjust the tension of the elastic strap to eliminate
the leakage.
Repeat the above fit check.

Filters Also 2000 Series filters.
Press your thumbs into the central indentation of the filters
(2000 Series), or press filter cover and filter body together
(6035/6038), inhale gently and hold your breath for ten
seconds If the face piece collapses slightly a proper fit has
been achieved. Figure 4. If an air leak is detected, reposition
the respirator on the face and / or re-adjust the tension of the
