Out of curiosity, what's the most efficient way to mask? Surely I'm not supposed to just buy disposable N95s in bulk, right? I don't know what the best method is. -- /Goadstool@hexbear.net
Me and my bodycount of 9205s:
So as I was laying bed unable to sleep in I went looking for some stuff.
Found a reddit sub dedicated to masks:
https://old.reddit.com/r/Masks4All/ - And they've got a pretty extensive wiki!
And then found a guy that's been reviewing masks, filters, and air quality meters for a while now.
https://breathesafeair.com/
He's got a bunch of reviews for masks and respirators. Here's some of his reviews for reusable Masks/Respirators.
Flo Mask Review - The Best Everyday Mask? - which I'm currently leaning towards.
Envo Mask Review - N95 Reusable Respirator
ElastoMaskPro Review - The Most Breathable N95 Reusable Respirator?
Also he recently did a write up on Mask for Kids
Best Kids Masks: 13 Best Certified Facemasks for Toddlers, Children & Teens
If you've got more resources, please feel free to share them in the comments, this was just some stuff I saved while tapping around in bed.
despite being such an extensive website that review guy does a bad job explaining how respirators and masks for 'everyday' are different. like yeah i get you want a 100% seal in a medical environment so a half-face respirator frame is desirable, but i don't understand the variant filter standards. he never calls the 'masks' n95 or anything but seems to imply that they're for covid. like bro i don't know what a mmH2O is, a PFE or a flow rate. is it suitable for blocking a virus or is it just for industrial dust?
those washable nanofibre ones look cool from a fit perspective, ease putting it on & comfort is important, but how much (if anything) am i sacrificing from a disposable n95? 
im way too stupid to tellTotally feel ya. I recommend checking out that Mask4all wiki. There's a lot of good info there that may help a bit.🤞

Great video from the Mask Nerd on this exact subject. The TL;DW is that once you have a quality respirator (e.g. KF94/N95) the quality of fit far dominates filtration efficacy. It's worth noting that it can be easier to get a good fit in an elastomeric (both because of their construction and because it's trivial to do a positive and negative pressure fit test without any equipment), but if you can get a good fit with an N95 you should be good to go for everyday situations (KF94s are difficult to get a good fit in because of the design, so I'd recommend N95s when possible). Of course, part of the problem is the difficulty in determining the fit for disposable respirators, since quantitative tests are out of reach for most (that's actually something the guy who made the video is working on). Maybe someone else here can speak to qualitative tests, which are more accessible. You can also see if there's a mask bloc in your area who may be able to direct you to a community fit testing opportunity.

I vaguely recall somebody posting a study here about how duck bill 95s were the best followed by cloth then regular 95s does anybody recall that? At least in the sense of the general public reducing virus transmissable breaths
I was just about to make a post on this exact topic lol. I had some questions:
The thing I'm most concerned about is fit while wearing glasses. I'm like a -4 or -5 so glasses are mandatory for me. Some masks have a bulky nosepiece so my glasses don't sit on them as well. Some masks also fog my glasses if I breathe too hard. Is there anything I can do to avoid this? Do I just have to try a bunch of different masks until I find a good one?
Personally, I usually rock the 3m Aura 9205+, occasionally the Aura 9210+, and they're really good about not fogging up my glasses like the over the ear kn95s. However I've also got the narrow rectangle lenses so what sits on the mask is largely just the nose pieces. I'm also getting to a point where I need to shuffle my glasses to the end of my nose in order to read things and the Aura's are the perfect distance to hold my glasses in place.
Best bet will probably be to buy one or two of a couple types and try them out. If you're looking to get a reusable, buy from amazon or somewhere that you can easily return without issue if it doesn't work for ya.
