@AmyZenunim @dx i have a bunch of those respirators, unfortunately they don't have an exhalation filter. but MSA has one which does. 3M doesn't have any half-masks which do exhalation filtering.
@AmyZenunim @ln @dx fwiw there is the add-on exhalation filter for 6000 series masks, the 604. https://www.3mcanada.ca/3M/en_CA/p/d/v101254496/
@AmyZenunim @dx MSA advantage 900 (i think) is the one I'd get for use in public
@ln @dx yeah, i have the MSA Adv900 with pink P100s. it's pretty good so far. was just wondering about this one, but it's good to know 3M doesn't have any I suppose
