High dust-holding capacity and long lifespan: Excellent dust-holding capability extends filter saturation time, reduces replacement frequency, maintains long-lasting stable purification performance, and is more economical to use. Low air resistance design: Optimized structure ensures smooth airflow, achieving high purification efficiency while maintaining purifier airflow, balancing energy efficiency and noise, and operating more quietly. Professional-Grade Filtration Efficiency: Uses high-efficiency filtering materials. The primary filter filters out large dust particles and hair; the activated carbon layer absorbs odors and harmful gases; the HEPA filter traps fine particles. Each layer has a clear role, providing comprehensive air purification. Convenient replacement design: Easy installation process, typically using latch or alignment structures, allowing users to easily replace the filter by following the manual, without professional tools.
