Does the use of air purifiers reduce second-hand smoke?

A. 1

You seem to be expecting too much from the air purifier.
The air purifier doesn't perform as well as I thought.
In order for the air purifier to perform properly, it must be air pollution in a completely enclosed space, but in general homes, it is constantly ventilated, so there is little pollution that requires an air purifier.

The air purifier filter wasn't good enough to remove cigarette smoke.
It might be possible for a very expensive air purifier.
