How do you ventilate when fine dust is bad?

fine-dust ventilation

The fine dust has been bad since a few days ago.

I've been without ventilation for about a day, but the air is so stuffy because I'm not trying to ventilate.

I was wondering how you guys ventilate.

Is there a good way?

You can't remove carbon dioxide or radon even if you use an air purifier
Open the window as short as possible, ventilate, and then turn on the air purifier to purify the air

It is said that there is a lot of fine dust outside, but if there is no ventilation inside the house, the air is not good
Besides the fine dust level, there's a lot of other things to ventilate
It's good to ventilate for a short time a day
