The first layer of product features dual ULPA filter: pollen, smoke and other particulate matter easily lead to pollen allergies, respiratory diseases and asthma incidence. ULPA for respirable particulate matter removal efficiency ≥ 99.9%, the smallest particles purify up to 0.0003mm; second layer of double activated carbon filter: formaldehyde, benzene is widely used in decorative materials, is a colorless gas with a strong pungent odor, it is high carcinogen. Activated carbon for formaldehyde, benzene removal efficiency reached 93.7% and 92.9%; third layer double Photocatalyst filter: Efficient degradation of toxic gases in the air, effectively kill a variety of bacteria. The sterilization rate and TVOC removal efficiency reached 97.6% and 97.3%; fourth layer dual UV ultraviolet light: the air is causing the spread of disease transmission the main way to purify the air is an effective measure to prevent influenza. With UV air sterilization technology, environmental natural bacteria kill rate of up to 97.6%; fifth layer of oxygen: oxygen is highly degradable organic odors, decomposition of the role of biological contamination, while the oxygen in air isolated oxygen atoms, to improve the oxygen content in the air. This machine produces 50mg per hour oxygen; sixth layer ion groups: negative ions by the medical profession as "air vitamin", people living in environments with high levels of negative ions, can promote human metabolism, improve immunity. This machine produces 5 million negative ions per second, the formation of ion group; seventh floor plant fragrance: sedative refreshing, fresh and aromatic plants emit. UV air sterilization technology innovations: the physical characteristics of UV germicidal applications, combined filter characteristics of the product, to achieve the UV light in the high speed air flow efficiently kill the bacteria. Photocatalyst filter: the use of nano-titanium dioxide (TiO2) materials, its superior oxidation function can destroy the filter to capture the bacterial cell membrane, freezing viral proteins inhibit viral activity. ULPA filter: The latest generation of electrostatic fiberglass considered material, can be captured cells are smaller than the particles. Activated carbon filter: walnut shell and using porous carbon composite technologies through modern biotechnology developed from activated carbon adsorption area of ??the machine up to 550000m2. Air quality human technology automatically detects: Built odor sensors automatically detect the various sources of pollution in the air, and automatically control the machine's operating status. Air purification degree indicator: When starting the sensor function, purification degree light through color change, you can display the current environment air quality situation. Auto Mode: Built-in smart chip, can be set "manual, automatic, timed, Sensor" mode. LED display: LED display, easier to use.
