Read your comment and then read mine. You make no sense and arguing with something I never wrote. So next time, you want to argue and tell someone has a useless comment, do take 1 more second to READ.Takada wrote: ↑ What a useless comment. Practically all surgical masks and KN95 masks are made in China. Good luck finding N95 masks now. As a HCP, it's hard as heck to find any unless you work in a hospital. We were rationed a few N95 masks as well several months ago. Guess where they were made? China. From my experience - N95>KN95>>Surgical Masks>Cloth masks. Costco typically doesn't sell garbage either and these look exactly like the ones we use.

Get masks with a metal clip at the nose( all N-type masks have those) then press hard against and you should be good. Your glasses fog up because there's no seal at the top(eg surgical/cloth type masks).

Apparently many N95 worldwide were shipped to China in January & February leaving supplies here empty. Once WHO finally officially declare pandemic in mid-March prices of N95 started rocketing upward - if you can find them! Then China/Chinese companies was selling N95 back at inflated prices - by late March - early April I watched 3M N95/KN95 prices increase from 5X to about 8X regular prices on AliExpress. It was all supply and demand. Folks were demanding N95 because that's what they were hearing in media - hospitals need disposable N95!pallfy wrote: ↑ I got the filters from Motion industries around March 18, and the half mask from Grainger. Amazon was sold out of both by that time, and later they had the full mask back in stock.
These work and safety equipment suppliers must of seen increased business pretty quickly, cuz by early april they were oos of almost everything. At the time I thought it strange that N95 masks were sold out much earlier than gas masks, cuz those are not reusable, like the 6 pairs of filters for $75 is more than enough to last me years.

And that's the reason these mask have a FAKE Chinese rating and KN95 is a BS rating. They falsely rate them whatever they want at the factory and off they go to clueless suppliers. These are definitely not good masks. If there's no seal, they are no better than surgical/cloth masks. Mask are such money making tool, every factory is switching up and printing them for clueless consumers who pay $100s of for literally $2 worth of masks.Asad_A203 wrote: ↑ I got one of these for woodworking and they definitely don't fit as well as an N95 mask (not a tight seal around the nose and loops around the ear vs the back of the head). I am sure it is fine for filtering saw dust but I noticed that chemical fumes are more noticeable than with an N95 mask (although, I don't think my N95 masks are intended to completely filter that out either).

So these do not offer 95% filtration. As Costco said, non-medical use.

Guess my hunt for a reliable KN95 / N95 continues...

So get the N type with the metal clip and the glasses won't fog up? Just find it a bit annoying when breathing and the glasses fog up haha. Then I can't see anything for a bit.

3M Aura series of respirators. Preferably with exhalation valve.

Hmmm one person said not to get ones with a breather valve or exhalation valve. As that could increase chances of spreading...
@chatbox The above person said to get an exhalation valve based mask to avoid fogging.chatbox wrote: ↑ Valves are bad for spread-prevention.

N95 respirators already collect moist droplets from breathing and talking. Most respirators with exhalation valves point downward which reduces the spread (if you're infected).
