3-STAGE FILTRATION SYSTEM Our Core 300 replacement filter features a true 3-in-1 composite structure: Nylon Preliminary Filter – captures large particles like dust and pet hair; Middle HEPA Filter – high-efficiency media for pollen, pet dander; Activated Carbon Filter – effective for smoke. Crafted with superior manufacturing processes, this filter delivers consistently efficient and stable performance throughout its entire 6–8 month lifespan.

HIGH-EFFICIENCY MAIN FILTER The middle main filter is constructed from true high-efficiency micron-level materials, with primary and support fibers precision-woven and cured, then machine-compressed into a dense waveform structure. This high-density, low-air-resistance design captures nearly all airborne particulates – including dust, pollen, and smoke particles – while maintaining optimal airflow for your Levoit Core 300 purifier.

PREMIUM ACTIVATED CARBON Our activated carbon filter is formed by sintering powdered coconut shell carbon, achieving an enormous internal surface area of 500–1500 per gram.

VALUE PACK & EASY REPLACEMENT Each package includes all required components for a complete standard installation – no tools needed! Simply remove the old filter and insert the new one in seconds. For optimal performance, we recommend replacing your filter every 6 to 8 months (depending on usage frequency and home environment).
