The Chinese seem to be constantly on holiday …
yes, and their holidays are long too, ours are nothing compared to theirs, at most 4 day weekend. i really wish we stole that from their culture
Jack just posted up his test video. Not exactly what I was expecting as I was imagining laboratory type setup with blowers and air quality meters measuring particulate matter before and after the filter. But I did learn something useful and glad to know some “form” of test was done, which I’m sure other sellers don’t. Considering some state govs are now recommending wearing cloth face covers or non medical grade mask, and per test results posted in my earlier comments, whatever FF sells will be more than adequate for non front line HCP
Not “effective only” but “more effective” — you can look this stuff up.
Exposure to small quantities of virus for ordinary people, versus exposure to large quantities of virus from infected people getting health care.
The term you’re looking to understand is “viral load”

I fully understand that. That was my point. It was the US Surgeon General and CDC saying that.
Here is CDC saying it
Though CDC finally changed their stance against wearing face mask 2 days ago

Just ordered some KN95s lets see when they get here. I have a bunch of different N95s from 3M that I bought at Home depot before the pandemic that I used to use for work. I will compare both and see.

Check box that says cooper…. [+$21]
Thanks. I placed the order. I hope they get here.
I think the holiday is over tonight, so hoping mine ship tonight/today.
Nothing shipped tonight. Here it says the Qingming Festival is April 4th through April 6th, so one more day: https://www.travelchinaguide.com/essential/public-holiday.htm
I got a response from Jack on a mistake I made when ordering - He said my order will be shipped in two days.
I also got a message from him saying 2 days to ship and 4-5 days transit
4-5 days transit?? Did you pay the $20 DHL shipping?
Yes I did. Its probably the one reasonable way to get them. Via snail mail its probably gonna take 2 months. And by that time it would be too late
Video tour of a Chinese mask factory. He performs the same quality test as Jack. The 3ply box of 50 seems the same this factory is producing. Looks reassuring, that they are good quality.
Logistic activities got impacted a lot by this crisis, hence going up in shipping prices and going down in shipping efficiency, and that’s what the other sellers from China told me. This Covid19 is no small issue.
Thanks for the sharing. For medical frontliners I guess the transparent, plastic type of mask is more effective in blocking all the droplets and particles, and they are washable and reusable also.
And I read from the news last week, a nurse from one of the hospitals in NY has resigned as she feels that she was not protected well at work. She was even asked to remove her face mask at work, and can anybody confirm if this is true? When we are urging the medical care takers to protect themselves, why would anybody ask them to remove their face mask at work?
Excellent find! The water test is an easy test to do too and would be useful indicator and can at least rule out the mask with poor filtration. I’ll direct this video to Jack’s attention.
Jack said the surgical mask he’s selling is one of the better ones with actual certifications and is hopefully from a factory as professional as the one in this video.
The issue right now with buying masks is while the large tier 1 factories in China can produce top quality masks, they are all booked by government, hospital, corporation contracts leaving the bottom tier factories producing masks for the smaller reseller market like the ones on Amazon, Ebay, and Ali. Many factories were recently repurposed to produce masks during the Wuhan outbreak and have zero previous mask making experience. A friend that is organizing a group donation to US hospitals have been told by their contacts in China that they found many fake or low quality masks being produced so it is important to source from legit factories. This is also what Fireflies found when testing samples from different factories.
But good thing I guess is any face covering is MUCH better than none as shown in the filtration test results I’ve posted above and even our gov recently changed the guideline to recommend wearing cloth masks or a scarf for the general public.
