Related, for those who havent seen, is Aaron Collins collection of mask test data https://docs.google.com/spreadsheets/d/1M0mdNLpTWEGcluK6hh5L...

I enjoyed his youtube channel. He discusses how he does the filtration testing here: https://www.youtube.com/watch?v=u4YdtH-ccMU&t=0s

Project N95 is the National Critical Equipment Clearinghouse for personal protective equipment (PPE), COVID-19 diagnostic tests and critical equipment. Edit: stupid typo on url, sorry https://www.projectn95.org/ US based non profit, not tied to amazon. I've bought their stuff. They are legit.

FYI it doesn't seem to work with the www. for me (https://n95project.org does work though, as does https://www.projectn95.org).

What’s the best mask for not caring about Covid but wanting everyone to think that I do? Is there a perfect balance between “double masking” and “American Flag Print Bandana”? I don’t want to go medical grade but I need something surgical that really evokes me in the trenches risking my life shopping at TJs.

One of the best mask I have found is Cloud Mask. Super light weight, highly breahable and doesn't fog up my glasses. It's also the most expensive mask in this format. Is it possible you can add this one?

I've spent about 1,000 hours on this with my team using a very expensive (~$250k) lab and I'd love for this to be a great resource for people when choosing a mask. The heavy lift we are doing here is around our particulate filtration efficiency test in which we do either the NIOSH N95 NaCL (0.3 micron) test or the ASTM 0.1 micron latex particle test. I'd love HN feedback on how we improve the interface and make this…

I looked at the linked page and it had a big list of masks, each of which linked to a page about that mask with a picture but no information such as test results. Was that intended? Could you just ditch all the fancy web design and have a big table with test results for each mask, with an ordering link for the models that you sell? That would be awesome.

It would be great if you also sold the stuff you use for testing masks. I spent a while looking into testing masks myself, but then the shortage eased up so it seemed less important.

Got the HDX N95 mask for a con over weekend I was nervous about, so very happy with its test results. First time I've used an N95, and first time I've shaved in quite a while. I now understand how difficult it is for healthcare workers and others wearing these for long periods of time. I didn't have an issue with breathing, rather my face hurt after just a few hours, primarily cheekbones and nose, and I wore it for many hours more than that over multiple days. To know it was an effective mask is comforting.
