got myself a 3M HF-802SD
+ the voice quality is so good!!
+ the suffocation button is a fun feature
+ just as comfy as my other 3M valved respirators
- "secure click" particulate filters look kinda silly without combination filters.

i might import american P100 particulate filters again to get the cool pink style back

@dx does this thing do exhalation filtering as well?

@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.

@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

@AmyZenunim @ln @dx fwiw there is the add-on exhalation filter for 6000 series masks, the 604. 3mcanada.ca/3M/en_CA/p/d/v1012

@AmyZenunim @dx MSA advantage 900 (i think) is the one I'd get for use in public

@AmyZenunim nope, but i've chosen not to care anymore. i've seen studies (can dig the link if you want) that show that exhalation valves pointing downwards are about as protective as cloth masks, and in the contexts i'd use these things, there's usually people not wearing any proper filtration at all
