The LEVOIT Core 400 Air Filter (Core 400S-RF) is a genuine 3-stage replacement filter designed for the LEVOIT Core 400S Smart Air Purifier. It is engineered to maintain high-performance air purification by capturing fine airborne particles, allergens, smoke, dust, pet dander, and odors. The filter uses a True HEPA-grade layer (capturing 99.97% of particles as small as 0.3 microns) combined with an activated carbon layer for odor and VOC removal. It also includes a pre-filter that traps larger particles like hair and lint, helping extend the life of the main filter. For best performance, it is recommended to replace the filter every 6–8 months depending on usage and air quality conditions.
