About Mouthpieces & Filters
The standard mouthpiece is our #1025. An alternate is #1018-MG plastic mouthtube, however this provides no protection from cross-contamination. We suggest you either use our # 1029 One-Way Mouthpiece (it allows only exhalation) or use our #3421 filter.
(# 3420 filter will also work) No mouthpiece is needed with the filter, use other end of filter port as mouthpiece.
