Digital display PM2.5 value / temperature and humidity sensors to detect dust air quality provided full circle LED lights can be equipped with a display of air quality odor sensor, temperature and humidity sensors with plastic AC motor, 3-speed governor anion can be absorbed by the body and sterilization Dust the UV disinfection has wifi reception port button lamp brightness can vary 24 hours timed shutdown, automatic protection system dump and lid safety devices provided air humidifying function according to the external light, with water reminder feature high sensitivity touch button operation, set switch , automatic, timing, velocity, sleep, UV lamp, negative ion, child lock button located eight early effect / HEPA / activated carbon / photocatalyst filter, with the first layer of the screen to remind the reset function: early pre-efficiency filters can filter ratio Cells also small dust, smoke and bacteria, prevent lung disease, lung cancer and liver cancer and other diseases. The air is the most harmful to human dust less than 2.5 microns, which is likely to penetrate cells and into the bloodstream. Second layer: formaldehyde filtration efficiency to formaldehyde unique complex filter can remove air contaminants, particularly formaldehyde and other harmful gases. Unique complex and efficient to use a granular activated carbon filter formaldehyde special treatment, cleans gases and other harmful gases containing formaldehyde. In addition, the filter can effectively filter out allergens and bacteria. Third layer: granular activated carbon filter Formaldehyde is widely used in building materials, is a colorless gas with a strong pungent odor, is highly carcinogenic. Granular activated carbon formaldehyde removal efficiency of 96.2%. The fourth layer: photocatalytic filter photocatalytic nano-particles when exposed to light of a certain wavelength of light generated by stimulated electrons and photogenerated holes photogenerated holes decomposition catalyst surface adsorption of water to produce hydroxyl radicals, photo-generated electrons around the oxygen reduction to the active oxygen ions, which have strong oxidation, reduction, all kinds of light pollution will destroy the catalyst surface, so as to achieve an air purifying effect. Fifth floor: HEPA high efficiency HEPA filters are High Efficiency Air FILTER (high efficiency particulate air filter) acronym, is internationally recognized as the best high filtration material, according to its unique fiber structure, antibacterial fiber processing through efficient control of microorganisms Integrated HEPA filter, effectively inhibit air allergens, such as dust mites, pollen, bacteria, secondhand smoke, dust and other tiny particles, the purification efficiency up to 99%, the smallest particles purify up to 0.0003mm. Sixth layer: photocatalytic filter degrading toxic gases in the air, effectively kill a variety of bacteria. The sterilization rate and TVOC removal efficiency of 97.6% and 97.3%, respectively. Seventh layer: UV ultraviolet light disinfection technology is a major pathway leading air diffusion spread of influenza, clean air is an effective measure to prevent influenza. Using UV air sterilization technology, environmental natural bacteria kill rate of up to 97.6%. Eighth layer: Anion negative ion technology is the medical profession as "vitamin in the air," people living in environments with high levels of negative ions, can promote human metabolism, improve immunity. The machine produces 10 million negative ions per second, forming ion group. Boost your metabolism, so you always feel being in the waterfalls, forest-like refreshing!
