@rick i did yes, I do have 3M HF-800SD with D9038 filters although it's not exactly the best fit for covid stuffs because of exhalation valve, there's stuff like msa advantage 900, which is a better fit not an expert in this at all
Owning both now (and having just spent 38C3 wearing the Advantage 900):
HF800SD Pros:
* More filter options incl. the amazing activated charcoal ones (I popped off the respirator for a moment the other day and was like "wow, it stinks of cigarettes here") * Lower breathing resistance * Filters last longer since they're not dealing with moist air
MSA Advantage 900 Pros:
* Much less heavy * Filters outgoing air (if this is important to you; it's not a major covid consideration for me most of the time these days because nobody masks) * Speech diagram is massively better * A bit less intimidating to people
@jeder@lilian@rick The filters will last really quite a while with occasional wear, they'll go much faster if you're doing really extended use.
Based on breathing resistance I think my first filter set for the Advantage 900 (I just got it before 38C3, and I wore it for the entire event) is toast already - so that's about 56 hours of continuous wear? But i think if I'd been taking it off and on more it would have probably lasted longer (because I think moisture accumulation fucks them up faster).
@erincandescent@rick@lilian also, while filters like D9038 have 5 years of usability, it's possible to get ones made in 2020 which is how my filters that I got last year, will be expired after may of this year, not exactly sure how that affects it though
