Guest guest Posted November 1, 2006 Report Share Posted November 1, 2006 NOISH is just a rating, not a brand of masks. It is particle size rating. I NOISH 100 will filter out more particles than a NOISH 95. I bought a NOISH 100 but the shape of it was too uncomfortable for me to wear for very long. The 2M mask probably has a NOISH rating on it. Look to see if you see a number with an 'N'in front of it. A NOISH 95, would be marked with a N95 somewhere on mask. Quote Link to comment Share on other sites More sharing options...
