I measured the Shadow Moon KF94 3 times above. Is legit results....at somewhat high ambient levels to stress test the mask. Else with ambient of 2-3k, even 5k, is not enough for all these very high filtration masks.
In fact, 14-16k particles/L @ 0.5 microns levels still not that sufficient for these masks, really need double that, preferably above 30k.



It's quite impressive. Able to hang around with the Good Manner, Bluna white and Bluna black.
Chamsarang is also good. F731 K-medic and Doctor P&B are very decent as well.


That time just before F919 came out, was intending to get this. Coz the packaging of the woman, like quite.....i mean, my wife likes it. :LOL: :s22::s13:

Can use $3 coupon. Not sure if can use free ship coupon simultaneously with a trick at $14.90 price.


From here


Page 4 and beyond

Read quite a number of people kaobei kaobu that they did not receive real KF94s, not SOL etc.
:LOL: But now cannot get liao.

F919 Chamsarang is also rather good, but 没有了 。

Can try F912 from Mezzang. Individually packed.
F808 Doctor P&B is also a good work horse, good for slightly larger adult faces of say > 1.7m 65kg (eg males like you). Cheap. 10 pack.

Like other things, just need 1 or 2 of these kind of people to spoil the whole soup :(

Ghost downstairs will see people chao keng anyhow wear, or even not wearing at all
Over here in SG Im waiting for 5 pax social grp / dine in for all to kick in, coz Xmas season coming also...... :unsure:

From the quanrantine hotel spread in HK, just that brief opening of the door to collect meals / leave trash outside coz the fella was maskless or wearing valved masks can liao.....delta can spread.

Same thing for lower efficiency masks, i dont think cloth masks does much for source control. (as confirmed with testing as well).
Nor do some other low efficiency disposable masks also.



Like this fake until cannot be faker KN95 one with very very low filtration, infected delta case @ peak viral shedding stand beside you 1m away for 15 mins wearing this super fake KN95......and you wear normal surgical mask. Dont think can block transmission. Can only hope / assume the viral dose is low enough so that you'd have a relatively mild symptomatic infection nia. <- and nobody really knows for sure what that level is, coz so many variables

For info, if buying @Qoo10, there's Q-reward 30% coupon max value $5, min purchase $10. Redemption starts at 12am, 26 Nov.
Better value than $3 coupon at spin wheel.

On 26Nov, just claim 30% coupon and use at non time-sale price listing is cheaper by $1-$2, can pay for shipping :s13:
Eg F731 @$12.99-30%=$9.09 is cheaper than time sale price listing@ $10.99.
Too bad F919 boh stock liao..

Someone sent me a relatively recent end Oct F731 to test.
Mine is a slightly "older" version, and is getting same results as all my other good KF94s. (Doctor P&B, Chamsarang, Shadow Moon, Good Manner etc)

Hmmm.......

But in the real world, can see my older and the other pax's version is not the same colour (mine is a wee wee bit peachy) and the outermost layer pattern is a wee bit different too.

Not totally sure if the newer KF94 can pass the KF94 standard or not. Tho the difference is small. But i guess can probably pass BFE 99% ba.

Ambient is somewhat high, 10k particles / L

Lazada doesnt really have cheap/good KF94 stuff.....only qoo10.

See the offer above. Got $5 coupon to get, then get from Mezzang seller. F808, F912 are good options to consider.

Suspect the fabric yarn got baited and switched by the supplier to the mask manufacturer, and the manufacturer also did not go test on PFE machine before accepting and putting into production.
Coz that time the original F731 OOS liao, then lots of people kaopei....then i guess he go pressure the manfacturer/line to push out 1 more time (maybe he placed order for say 5k packs? Doable one).

Actually it's not difficult, just have to get the equipment. Heck, as you can see, even my $60 DIY equipment relying on just ambient non-hazy air able to sniff it out.

Luckily I didn’t buy a lot of the Anhui Duojian KN95s 😂 absolutely fake, worse than surgical masks even...

Really is a matter of luck coz A.MK KN95 and Anqing Xinxin KF94 could be just as bad. As we all know MIC masks are rather inconsistent. Here is where your testing comes in handy.

Seems like this seller, you never know what you are getting. The teddy bear which many reviewers got is 3 ply. Doesn't mean it's bad, but advertise 4 ply, can't settle for a 3 ply.

Actually is worse than the $2 per box of 50 MIC flat masks. Those still measure better, coz at least got legit meltblown.

The xinxin and A.MK are probably good BFE 99.9% fabrics.

Can consider the F808 for a > 1.7m 65kg male. That one tested, and so far so good.

F912 seems promising, but haven't tested.

Tested yr Bamboo masks already.

I cut it up as well, seems like no meltblown. 4-ply. Damn breathable though.....
