How many KF masks should I wear to block ultrafine dust?

ultrafine-dust fine-dust kf mask

I want to buy a mask that blocks ultra-fine dust while blocking general fine dust.

I heard that the KF level indicates how much it blocks, but I was wondering how many ultra-fine dust blocks are there.

Is there enough KF80 with a low price?

Or do you need a higher one?

I'd appreciate it if you could also recommend the product

In terms of terms, ultrafine dust is less than 2.5 이하.
KF80 means that it can block less than 0.6이하 by 80%.
KF94 means 94% can be blocked.
So if you think about blocking ultrafine dust, you block both.
The disadvantage is that it is difficult to breathe if the number is high.
You can use it and choose the appropriate one.

If you use something that's good to breathe, you can use a filter
I recommend 3M 8822
The downside is that it's for industrial use, so you have to be able to bear the shameLOL

If you want to block fine dust, it needs to be at the industrial level to be sealed and blocked, so I recommend 3M products
The 8822 you recommended is good, too
