kF94 or Surgical mask?

[windwaver]

Yes, definitely. For lite to even moderate crowd/risk use, can consider. The cream and white (qoo10 source) is basically a mixshop. Esp if one and surrounding family members that come into contact have no underlying.......really don't see why not.
The "lint" of the innerply is ok, won't really come loose easily. Seriously these masks are really meant to be changed every hour or two or so. When i get back to office to settle stuff or go onsite etc, i easily do 4 daily.
Esp if there is much speaking.



Not really, there are masks which are more breathable yet filter better. Eg the F731 K-medic in the same vid, it measures better and is more breathable. Might have something to do with the electrostatic quality.
I have measured chinese stuff that are even thicker, more unbreathable, and measure much worse.
eg the below vid PM2.5 pad vs MIC KF94, the PM2.5 pad is really thick (easily 2X as thick as say a F731 K-medic) and after i opened it up the double layer meltblown is thicker.


But of course that is comparing south korean fabric with chinese fabric, the latter is really built to a price point, ie value for money and still performs decently.

So if it's Moleshi vs these Anhui ruierxin masks (mixshop, EZlifeSG), then probably yes. I would not be surprised that say the former is using say 30 gsm and the latter is using 38 gsm. Then of course the corresponding breathability and filtration would scale accordingly.

Sounds good, I'm looking for a mask that can do lite to moderate outdoor exercises. Seems like can buy from either EZlifeSG (Anhui ruierxin) and JW Collection (Moleshi).

As for indoor, really crowded situations, I'm using F929 which is perfect.

Oh that honeywell H901 kn95. Yeah a lot of fakes.

I have one box left of Honeywell N95 H801, bought in the early days of Covid, from seller in Sg.
It's the old school type - hard shell, like 3M 8210.
There is no expiry date. I guess should be legit and ok to use ba.
The form strip still ok.

Yeah, I learnt my lesson.
If the foam strip disintegrate, I'll replace them.
Not going to be silly and dump them like what I did for my super old 3M 8210 (when the foam strip disintegrated)
Anyway just 1 box, ie. 30 pcs left la.

Actually just use up these H801 and be done with them. Now you have legit KF94s at such low prices . The only +ve about the H801 N95 is that they are headstraps with much stiffer nose wires, ie able to seal properly even without surgical tape.

I think Moleshi more suitable for say brisk walking, slightly more breathable. None of any of these fully covered mask types are suitable for jogging, it'd be a little risky.

Have just mailed out today. Total: 4 pcs of mask.

Thanks in advance

Callie surgical, iconnic, Yukazan KF94, Safeair KF94, Anhui ruierxin (EZLifeSG qoo10)

The Yukazan KF94 is not a true KF94.
But usable for lite uses.

Safeair KF94 shd be a legit KF94 (smells like one too). But need higher ambient levels to 100% confirm.

Someone is gonna send in the F527, Hanmaum KF94 for me to test. There are other sellers selling this as well other than Mezzang.

Armburst tested it to be 99.79% (0.1 microns) but breathability is not that good.
In comparison, Good manner is only at 108 Pa. twice lower breathing resistance
But filtration is in the same ballpark

Good manner FTW but it's more expensive..

hi, can check about the sizes of the masks from mezzang? I think f731 fits ok for me, just that sometimes feels a bit tight. tried f810 which feels a little big, while I read that f808 and f801 are much bigger than f731?

how is f929, is the fit closer to f731 or is it much more comfortable to wear?

Try the Blue pine F912. I find it just a little bit bigger than F731.. Probably won't notice much diff if never put side by side comparison.

I'd recommend that you try F912 as well.

I started off with F731, like many here, also bought F929 and F912. F929 if you want black and 4-ply, but size-wise I'd say go for F912.

Hanmaum one is good, I bought 50 in a box, slightly bigger

thanks for the suggestion I'll try the f912, shall see if the nose cutout is better or not haha

scrolled few pages above,noticed that the f929 is actually smaller than f731?

i have both 929 and 912 as my daily. 912 is bigger and 929 is a bit tight for me. The 912 can poke my lower eyelashes till always very itchy haha.

trying to understand how 912 poke your lower eyelashes

I have this issue as well. This only occurs when i look downwards. My dbl chin will push the mask (Lower flap) upwards touching my lower eyelids. Normal looking forward position is alright. I tried using my specs nose bridge to "lock' the mask in place. Previously using Good manner have this issue as well, I faulted the mask for being small. End up i realise is my dbl chin causing the movement.

wah ok, is it because you wear it higher up on your nose? sounds like 929 is more suitable for those looking for smaller sizes...

anyway was wearing f810 today (got a free sample in oct), I could feel quite a bit of lint in the innerply after a day of usage, might not be suitable for those that are looking for smooth innerply

u mean the upper flap on nose bridge moves up and poke your lower lashes when u look down?
Could it be the mask is slightly big for u or the flaps are bigger than normal?

I do not know if 912 flap is bigger than normal. The only way i tried is tying the earband behind my head. It still moves slightly. Though there is this small inconvenience i still prefer 912 then others. But will be trying 731when stock arrive.

Theres more material on top of the nose wire compared to others, 731 feels so loose to me
