The HEPA filter in your Levoit Core 300S captures microscopic particles like dust mites, pollen, pet dander, and mold spores, improving indoor air quality. Over time, these particles accumulate on the filter reducing its effectiveness. For optimal performance, it's important to replace the HEPA filter every 6 months. Neglecting replacement can lead to reduced airflow, decreased filtration efficiency, and potential strain on the device motor.
