When another option is the better fit

A higher-CADR purifier

Choose this when the room is larger or faster air cleaning matters more than size.

A quieter compact purifier

Choose this when night use and close placement matter more than peak airflow.

Source control or ventilation

Choose this when the pollutant source can be removed instead of filtered.
