Powerful circulating ventilation system, continuous air supply: The axial flow fan runs at a speed of 1650 RPM, so it can accelerate and penetrate clean air through the filter element without stopping. Innovative honeycomb design increases air intake and reduces wind resistance. The spirally widened air duct design makes the air flow more smooth and efficient.
High-quality Filtration Technology: The filter element can be used for up to 500 hours, and the air pump can be charged through the USB port.
Simple Three-step Adjustment to Prevent Puffiness: The face mask contains three options of 2.35, 1.77 and 1.18 CFM. Advanced 2.35 CFM is used for physical labor and sports. Use intermediate 1.77 CFM and low 1.18 CFM every day. By default, there is an automatic fresh air supply mode, which filters external air through H13 HEPA and pushes it out along the circular air duct.
High-grade Effective Filter Material: 99.9% PM2.5 filter: use H13 HEPA high-efficiency filter material, 99.9% PM2.5 filter in the air, which can effectively intercept harmful gases, dust particles, hair, pollen, chemicals, hand smoke and other harmful substance.
