The Activated Carbon Filter in your Levoit Classic 300S helps remove odors, smoke, and volatile organic compounds (VOCs) from the air. Over time, these pollutants build up on the filter's surface, reducing its effectiveness. Replacing the filter regularly ensures your air purifier continues to perform optimally. Delaying replacement can lead to reduced air quality and a less effective odor removal.
