As a global pioneer in cleaning technology, Dreame is dedicated to revolutionizing the air purification field through core innovations in high-speed motors, fluid dynamics, and intelligent algorithms. Addressing the industry pain points of low purification efficiency and uneven coverage in traditional devices, we spent over 300 days developing the groundbreaking Dual Airflow Intelligent Control System, shattering the industry's "impossible triangle" with a 133% airflow increase, 10-meter air projection distance, and unchanged noise levels. The PM20 features a 7-in-1 Ultra-Sensing Chip that monitors contaminants from 0.1μm particles down to 0.001ppm molecular-level pollutants in real time. Integrated with a six-stage purification matrix – including catalytic decomposition filters, UVC ultraviolet light curtains, and plasma sterilization – it achieves 99.97% purification efficiency and full-space pathogen elimination. Our proprietary "Wind Follows Motion" millimeter-wave radar technology enables 5-meter activation and 120° human tracking, transforming the device into an proactive air steward. Certified by TÜV Rheinland Allergen Certification and CHEARI Maternal-Infant Safety Standards, the PM20 combines aerospace-grade engineering with artistic design to create a year-round air hub: delivering 3-second rapid heating in winter, three-dimensional airflow in summer, and deep purification during seasonal transitions – redefining breathable freedom beyond spatial constraints.
