Electronic air cleaners are typically wired in parallel with the appliance blower fan motor to ensure that the air cleaner operates continuously whenever the blower fan is running. This wiring configuration allows the air cleaner to receive its power supply directly from the same source as the fan motor, maintaining consistent airflow through the air cleaner while it actively filters the air.

Wiring in parallel ensures that if the blower is operating, the electronic air cleaner is also functioning, thus maximizing the efficiency of the air filtration system. It allows the air cleaner to filter particles and contaminants from the air being circulated throughout the space.

In contrast, serial wiring would mean that the air cleaner only operates when the fan motor is activating to flow air through it, which may reduce its effectiveness as it could lead to situations where the air cleaner is not functioning when the fan is not running. Also, wiring configurations that involve complexity or redundancy—like additional components in series—can adversely affect performance or lead to potential failures, which is avoided by the parallel setup in this context.
