The HEPA Filter in your Levoit Core 300S traps tiny airborne particles like dust, pollen, and pet dander to improve indoor air quality. Over time, the filter becomes clogged and less effective. Replacing it regularly ensures optimal filtration and airflow. Delaying replacement can lead to reduced performance and potentially damage other components.
