What should I buy when I buy a mask for fine dust?

A. 1

You can use the kf80 level first. Mask grade test particles are much smaller than fine dust. 95 is better when fine dust is very bad, but it will be harder to breathe.

There's a class called KF.
In the case of masks for fine dust, you can buy them with a number over KF80.

If you look for a mask for fine dust sold in the market, it says KF80, KF90, and KF95.
The higher the filter, the better, but it's hard to breathe Hah!
