These days, fine dust is severe, so I wear a mask when I go outside. I can't even wear a mask at home. I wonder if it's right to have a lot of fine dust at home.
If I use an air purifier, can I really catch fine dust?Or is there not much fine dust in the house?

There's a lot of fine dust in the house, too
It's good to use an air purifier
If you turn on the air purifier, you can see the level of fine dust.
On days when there is a lot of fine dust outside, fine dust is also huge indoors.
It gets worse when you ventilate it.
If you use an air purifier, you can see the decrease in fine dust.
