ADVANCED ACTIVATED CARBON FILTER: Activated carbon is very proficient because of its Mini and macropores that can pull molecules into itself thereby absorbing them. This carbon filter helps you to effectively deodorize the air in your home by reducing household odors such as cooking smells or cigarette smoke. It also removes lint, pollen, pet dander, and dust. These large particles will be trapped in this first line of defense and extend the life of your True HEPA filters DURABLE CONSTRUCTION: The Advanced activated carbon filters were thicker to catch more particles in order to protect the other filters as well as your air purifier. Our product has high-quality absorption without disrupting airflow because it has more carbon fiber per inch and be more durable than the other carbon filters WASHABLE: The product can be easily removed, be washable, and reusable. It helps you to save time and avoid unnecessary fees because the life of the filter can be extended and you need to replace it less often (about 3 - 6 months depending on the usage and the environment) instead of replacing a thin carbon filter every 1 - 2 months EXACT REPLACEMENT: Our premium LV-H132 Pre-filters fit for Levoit LV-H132-RF Colour:black Material:plastic Package Contents: 2 x filter elements Only the above package content, other products are not included.
