Why is the concentration of fine dust in the air purifier not dropping?

air-purifier fine-dust

Hello.

I bought Xiaomi 2s now.

It's been an hour since the air purifier was turned on, but the concentration of fine dust continues to be around 30.

Even though the window is closed.

It's true even if you play it hard.

Is it supposed to be like this?

So when the fine dust level is severe, it stays high to a certain extent
