Which factor primarily contributes to the effectiveness of an electronic air cleaner?

The effectiveness of an electronic air cleaner primarily hinges upon the technology used in particle capture. This technology typically employs processes such as ionization to charge airborne particles, causing them to adhere to collector plates within the air cleaner. This method enhances the removal of even small particles from the air, including dust, pollen, smoke, and other allergens.

A cleaner that utilizes advanced particle capture technologies can significantly reduce the concentration of pollutants, leading to improved indoor air quality. The design and implementation of these technologies dictate how efficiently the system can operate, making them central to the overall effectiveness of the electronic air cleaner.

In contrast, while the type of electrical components, efficiency rating of the filter, and airflow design are all important aspects of an air cleaner’s performance, they do not directly address the core mechanism of how particles are captured and removed from the air, which is a critical function of electronic air cleaners.
