Masking with n95 or higher rated masks (95% efficacy or higher) is really important these days if you want to avoid COVID, mitigate air pollution from near constant wildfires, and now this.
However, I understand that not everyone can afford to keep buying good masks, or have a nice enough climate to be able to wear one outdoors. if the weather is too warm & humid, you’ll likely die from heat exhaustion instead.

More common these days is to buy farm equipment that is enclosed and has a good cabin filter, ideally HEPA but unfortunately there are many tasks that must be done manually.
- myself248 3y agoThere are plenty of DIY PAPRs now, many of which need some refinement to be truly comfortable, but they're certainly affordable.
- LinuxBender 3y agoYou've got my interest. I would love to see some articles if you have any handy. I found some cheaper off-brand PAPR's on Amazon but they have really bad reviews and look sketchy.
- CiteXieAlAlyEtc 3y ago> However, I understand that not everyone can afford to keep buying good masks As a tip for fellow price-constrained folks out there: upgrading to an elastomeric respirator can help substantially with costs. Dentec's marketing copy suggests about a 90% reduction in costs compared to using disposable respirators [0]; given a pack of 50 duckbills on projectn95 [1] is roughly the same price as a new elastomeric w/ filters [2], seems to check out. As an added benefit, going in on an elastomeric can help a bit with both mask fit and comfort.

- gretyuph 3y agoIt’s crazy to think about but we may soon be in the dystopian future where everyone has a rebreather system while they walk around in grungy neon lit cities. It’s preparing us for what colonizing other planets might look like I guess.

- dingnuts 3y agoIs there any evidence of a sizeable effect from wearing masks outdoors, especially considering the risk of transmission outdoors is so much lower than indoors[0]? I thought this practice was debunked early in the pandemic. Even indoors, the effect is small at best[1], but outdoors the volume of air and other factors contribute to the near-impossibility of effectively transmitting any serious kind of live viral load. 0 https://academic.oup.com/jid/article/223/4/550/6009483 https://academic.oup.com/jid/article/223/4/550/6009483 1 https://www.cochrane.org/CD006207/ARI_do-physical-measures-such-hand-washing-or-wearing-masks-stop-or-slow-down-spread-respiratory-viruses https://www.cochrane.org/CD006207/ARI_do-physical-measures-s...
- throwaway290 3y agoValley fever fungus survives outdoors, so the mask can help. COVID does not, so the mask is good indoors or in crowds.
- chaostheory 3y agoIf you’re referring to only COVID, you’re right. Wearing a mask outdoors is pointless. It only makes sense indoors, but I was also referring to air pollution from wildfires and Valley fever where both are still dangerous outdoors
