Wait - this actually works? Are you saying having a air purifier will reduce the dust that accumulates on open surfaces and that one will not need to dust any more (or can go for longer periods that usual before they need to dust)?
I got a cheap air purifier (~$40 on amazon) and didn't notice any improvement. The filter gets dirty over time so it's doing something, but I just don't think there's enough airflow for it to matter. More expensive options might be more effective but I don't want to burn the money to find out.
