Features: Equipped with advanced four-layer catalytic filter technology, oxides, ozone molecules and contaminated air will sucked into the MAF double-effect filter by the exhaust system, and the viruses, bacteria, etc. in the air react inside the tunnel, and then decompose again. In order to achieve a safe and effective air purification effect. MAF nanofiltration technology, adsorption of microporous particles, clean air and release 3 million / cubic centimeters of negative ions. Using double-effect nano oxygen ion generator to reduce energy consumption and control of the amount of nano oxygen ions generated. Covering an area of 50 square meters, designed 360 air circulation from the bottom to top, both home and car can be used. High efficiency air filter and MAF double effect filter, removable, easy maintenance and replacement. Intelligent touch system, low-speed high-speed free to switch. The product comes with a removable base, can be placed vertically and horizontally, placed in the car vent cup holder, ventilation is more smooth.
