Advanced Activated Carbon Filter: Activated carbon is very adept due to its Mini and Macropores which can pull particles towards itself, thereby absorbing them. This carbon filter helps effectively deodorize the air in your home, reducing household odors such as cooking odors or cigarette smoke. It also removes lint, pollen, pet hair and dust. These large particles will be trapped in this first line of defense and extend the life of your true HEPA filter. Durable design: Advanced activated carbon filters were thicker to catch more particles to protect other filters as well as the air purifier. Our product has high-quality absorption without disturbing the airflow because it has more carbon fiber per inch and is more durable than other carbon filters. Washable: The product is easily removed, washed and reusable. Helps you save time and avoid unnecessary fees as the filter life can be extended and need to be replaced less frequently (approximately 3 - 6 months depending on usage and environment) instead of replacing the fine carbon filter every 1 - 2 months Accurate replacement: our premium LV pre-filters H132 fit LV-H132-RF Levoit Color: Black Material: Plastic Package Contents: 2 x Filter Items Only the above package content, other products are not included.
