The HEPA Filter in your Levoit Core 400S is responsible for capturing microscopic particles like dust, pollen, pet dander, and mold spores, improving the air quality in your space. Over time, these particles accumulate on the filter, reducing its effectiveness and airflow. Replacing the filter regularly ensures optimal performance and clean air.
