Multi-layer composite structure: Carefully engineered multilayer filter screen where each layer serves a specific function. The primary filter captures large particles, the activated carbon filter absorbs odors and gases, and the high-efficiency HEPA filter traps tiny particles. Each layer is tightly controlled to clean the air comprehensively. Durable longevity: High-quality, wear-resistant filter materials ensure efficient filtration while extending the life of the filter screen. Under normal use it can run continuously, reducing the effort and cost of frequent filter replacements. Low air resistance design: By optimizing the filter’s structure and materials, air flow resistance is reduced. Filtration remains strong without compromising the purifier’s air volume, boosting cleaning efficiency and promoting more uniform room air circulation. Easy maintenance and cleaning: Some filters can be easily washed with water or wiped clean. This extends filter life and lowers running costs. Regular cleaning helps sustain filtration performance. Use scenarios: - Living rooms and family spaces: reduces dust and odors from daily activity and pets while maintaining quiet operation. - Bedrooms: supports a cleaner sleep environment, particularly for allergy-sensitive individuals. - Offices or study rooms: helps maintain a fresh, productive workspace by reducing dust in small to medium spaces.
