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't tell if it I'd KFDA certified as there no indicator and the brand I received is shadow moon
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.

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.

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.

@WussRedXLi

Paiseh, didn't read through all the pages. How come got so many F### series ah? which one is more recommended to buy ah?

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.....

Hands itchy to wanna hoot 2 qty of this. Either this or 2 qty of F912 Blue Pine KF94.

2 packs can get free shipping (must use the add another item eg Good Manner, apply coupon, then take away the Good Manner) simultaneously 2 coupons usage, together with $5 off black friday coupon in Q rewards.
End up 14.90 shipped to SG for 100pcs. Got another 100 Qpoints so $13.90.

Not sure if it is legit BFE 99.9% (they claim the packaging's BFE 95% is generically printed, fabric is 99.9%), . Not aiming to get like 0-26 particles/L performance on the meter @ 10-15k ambient. That is legit KF94 masks kinda performance.

If can get 50-100 i think i would be more than fine liao (of coz as close to 50 as possible :LOL:). Also can use for SG haze.

Best for rough use at such prices.

Not sure if the cutting is good or not. Not many reviews from KS Mall and Good Sell.
But the quality generally are all ok. *shrugs*


Will be a leap of faith for $13.90. *shrugs* If performance is decent as in BFE 99.9% type, then hit jackpot.

I mean lets face it, the best of the best of KF94s are really good, thing is.......when do we see ourselves mingling in say CNY pasar malam kind of conditions or Xmas in aircon shopping mall crowded conditions?
Or spend > 30 mins in crowded MRT trips?
For me, really quite rare. Current stock already more than sufficient

They call these summer masks. It's like last time F506 and F505. Now i think after alpha and delta came, they bothered to put meltblown liao.

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

share with you personal experience

during my SHN at govt designated hotel from a trip from Germany, daily can smell other rooms preparing coffee, sometimes can smell cigarette smoke (should be from someone cannot tahan, then hide inside room smoke, but firealarm never sound also...)

I doubt hotels and other quarantine facilities really have proper airflow directions and full HEPA capabilities; if an infected person cough in his room and the airflow goes to other nearby rooms also you know what can happen...

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..

walau F919 you guys made it OOS already!!

F series is based on facial features ah?
Nope, just a specific mask model denoted by that particular seller/shop for easier reference.

For eg, the F731 and F730 masks are really called K-medic

F808 is called Doctor P&B

F912 is Blue Pine.
