Product Features The first layer HEPA filter: pollen, smoke and other particulate matter easily lead to pollen allergies, respiratory diseases and asthma incidence. HEPA for particulate matter removal efficiency ≥ 99.9%, the smallest particles purify up to 0.0003mm; second layer of activated carbon filter: formaldehyde is widely used in building materials, is a colorless gas with a strong pungent odor, it is highly carcinogenic. Activated carbon for formaldehyde removal efficiency of 96.2%; third layer 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 of carbon fiber filter: Benzene is widely used in decorative materials, there is a strong aroma, benzene will seriously damage the human hematopoietic system, leading to red blood cells, thrombocytopenia. Benzene, carbon fiber filter for purification efficiency up to 92.5%; fifth layers 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%; sixth floor 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; seventh 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. 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 Show: with LED display, easier to use. Automatic alarm, automatic power-off safety protection, the use of ultra-quiet PG motor.
