ACTIVATED CARBON FILTRATION: This replacement filter is designed with an activated carbon layer to help reduce odors and improve indoor air quality in everyday environments.

ODOR & VOC CONTROL: The carbon media helps reduce smoke, cooking, and pet odors, while also helping absorb volatile organic compounds (VOCs) emitted from common household products and materials.

PRE-FILTER PROTECTION: By capturing airborne pollutants before they reach the main filter, it helps reduce system load and extend the lifespan of your air purifier’s primary filtration system.

EASY INSTALLATION: Designed for quick and simple replacement, making routine maintenance convenient and hassle-free.
