I am still fine and unvaccinated.But there will be gap on both side which is no good leh. Kf 94 can cover tied fit both side of the face.

So u went for test every week 2 times?I am still fine and unvaccinated.
Stop my Taxi business already. The ART tests too costly for me.So u went for test every week 2 times?
Then now not driving ?Stop my Taxi business already. The ART tests too costly for me.
Go and take up security course good pay.Stop my Taxi business already. The ART tests too costly for me.
I am not vaccinated. No companies want hire me now.Go and take up security course good pay.
Take up course only what for future use . Can use skill future to claim right . Then why dont take china vaccine ?I am not vaccinated. No companies want hire me now.
I am also wearing double surgical masks now.
No choice for ppl like us no money to buy quality N95.
Double masks seal the side gaps better as it's tighter.
With 1 surgical mask, the side gaps are wide open.
Don’t accept anything other than N95Besides N95, which is better KF 94 or surgical mask? Women who love to be swee swee choose KF94. Does it have better protection than surgical mask?
Yes . I have small face . Normal mask with leakage. Double no leak n it fits so well
Anyway, it's already 3.577k now. And Rt is not really approaching 1.0 fast enough so that we can drop cases.Yes . I have small face . Normal mask with leakage. Double no leak n it fits so well

Anyway, it's already 3.577k now. And Rt is not really approaching 1.0 fast enough so that we can drop cases.
So, not really the time to be playing guessing games. For all you know, 1 cabin you dont have 1, but 4-5 infectors now. The load is gonna be very high.
I am still taking the time and sharing data with you coz i know you have unvaccinated pax in your family. And guess what bro/sis, the hospital system isnt exactly in a good shape right now, unless if you can go private.
Just get something that works as per data measurements or way of wearing. If you want to 3M micropore tape the 2 sides and also the top of 1 x ASTM leve 2 surgical mask, also ok.
You are aiming to filter the worst case scenario called droplet nuclei, which peaks at around 1.0 microns (it's a log distribution curve). In short, they don't dip below 0.4-0.5 microns for the smallest ones. 1 single virion does not get expelled by our airways and float in the air by itself, already measured scientifically before, so don't worry about those 0.08-0.1 microns figures (80-100 nanometers).
So don't worry about KF94 or N95, they can easily handle the challenge aerosol size which is a bit bigger than the MPPS.

Ya but who would have $$$ to use them all times.
Our whole family are not vaxx...
I have friends who work as medical staff in hospitals. .... Not convenient to say about hospitals but basically do get good care of yourself. Don depend on government.
Thanks for sharing so much info about mask. Too technical for me to understand. Basically as long as there is no leakage , it should be working well, right?
You may want to try good manner and blue world mask. These 2 are affordable and have strong electrostatic + comfortable with tight fit. I have small face as well so I need to use a mask hook.Ya but who would have $$$ to use them all times.

For
1. N95
2. Legit KN95 (the cheapest KN95 that is legit tested by CDC in a past exercise costs ~ SGD 0.4 each, not those rmb 80 for 500pcs "KN95" on Taobao)
3. Made in Korea KF94
4. ASTM level 1 to 3 (look at the box, got say) or EN13486 IIR masks (look at the box) surgical masks
As long as no leak, ie you tape up, use sealing gadgets, or the mask itself already can provide no leak, yes it would work.
Note, double surgical masking, you or others might think "no leak" coz you see holes smaller. Trust me, i go test for ya, i will be able to show you the leak.
That is why KF94 MIK ones 90% of the case still need 3M micropore, if you really care about it.
There is still leak from MIK KF94s, even with that visibly tight fitting looks of it. Stuff like the loose earloop and overly soft nosewire wont help
For general population, NIOSH N95s, still would leak i think > 50% of the time, just leak less nia.
That is why i ask you folks to do 3M micropore or any surgical tape seal.
But remember, the above masks the filter has higher airflow resistance than your MIC flat masks or cloth.
That small 1mm gap for cloth mask leaks just a little, but it's gonna leak a heck lot more for the N95s.
That very small gap is very significantly for the above 4 types of masks.
