[Improved Filtration Performance] The Vital 100S filters feature an upgraded 3-stage filtration system that uses HEPA material to effectively capture 99.9% of particles as small as 0.3 microns. This includes common household allergens such as dust, pet dander and pollen, ensuring cleaner air in your home. [Fight Household Odors] Designed to tackle unwanted odors, the Vital 100S replacement filter includes a high-efficiency activated carbon layer. This effectively eliminates pet odors, smoke, cooking fumes, improving indoor air quality and promoting a healthier living environment for both pet owners and smokers. [COST-EFFECTIVE] We recommend replacing the LEVOIT 100S air purifier filter every 6-8 months for optimal performance, depending on usage and environment. Installation is easy and no tools are required. Simply replace the filter as needed.
