Not all dust will be floating in the air all the time. Only lighter particles floating in the air gets clean by air filter
Heavier dusts will settle on the floor, furniture, etc.
Your PM2.5 reading of 20-25 is very clean air already. I set mine to turn on by itself when it reaches 50
Even 50 is consider clean

No wonder some of the dust remains on the furniture.
BTW, you can feel some good breathing if using air purifier.
When got budget, I will purchase for the bedroom and the other rooms.
Or, when the RM improve a bit...ahahaha
