This 3D cross-section illustrates a high-performance air purifier’s internal architecture, featuring a colored layer stack: yellow pre-filter for large particles, pink HEPA filter for fine PM2.5 and allergens, purple activated carbon for VOCs and odors, and optional UV-C chamber for germ inactivation. The airflow path is clearly visualized, emphasizing laminar flow design and sealed housing to prevent bypass leakage. Structural elements like the motor housing, intake grille, and outlet diffuser are also labeled for technical clarity.
