In terms ...
CTM or CTL 26?
CTM 26: "For dust with MAC values > 0.1 mg/m?". According to those specifications, the CTM provides better filtration for fine dust applications such as concrete. The question is, how is the better filtration achieved? Both the CTL 26 and CTM 26 use the same filter (496171) and the same bags (496187).
