What is one advantage of using electrostatic filters?

Electrostatic filters are designed to enhance air cleaning efficiency by utilizing an electrostatic charge to attract particles. One significant advantage of these filters is their higher efficiency at lower airflow rates. This attribute makes them particularly effective in applications where airflow may be compromised or reduced, allowing them to maintain a high level of performance in trapping dust, pollen, and other airborne particulates.

Other types of filters may struggle to perform effectively under similar conditions, potentially leading to inadequate filtration in environments where air movement is restricted. The ability of electrostatic filters to capture a greater percentage of contaminants even when airflow is suboptimal distinguishes them from traditional filters.

While other options may suggest advantages like cost, maintenance, or disposability, these aspects do not accurately reflect the core benefits associated with electrostatic filter technology. Thus, the choice highlighting higher efficiency at lower airflow aligns best with the strengths and design purpose of electrostatic filters.
