YM-A4002 air purifiers air purifiers tall yet

 We recommend that you choose an air purifier to consider the following main air flow: good air purifier ventilation speed must be fast, that wind capacity in the product specification to (m3 / h) to represent, the better the value. Purification efficiency: choose clean and efficient products, specifically to see the removal of the solid particles, the removal of volatile organic compounds, formaldehyde removal, these three indicators are usually expressed as a percentage, the better the value. Filter: the mainstream air purifier filters for each layer for different pollutants, such as: pre-filter can absorb small dust particles and hair; deodorizing filter multi-finger activated carbon filter can remove sweat smell, pet odors such as smell; formaldehyde removal filter is designed for formaldehyde; HEPA dust filter is used to remove dust mites, pollen, bacteria, secondhand smoke, dust and other tiny particles requires special attention is filter replacement frequency and filter cost, how long to replace one, in fact, according to the frequency and extent of the contamination. Noise: As long as no more than 30 db, would not affect sleep at night in the bedroom, then choose a mute function or sleep mode products. Non-silent mode noise'll sleep under the influence Application area: Each air purifiers are marked Approximate area. It can be used as an optional reference. It is noteworthy also taking into account storey house, if the size of the standard height of more than 2.8 meters, then you should take into account this factor, buy a larger area of ??suitable products. Security: look for 3C certification, buy the regular manufacturers. A perfect after-sales service of the product manufacturers. First layer: Pre-Primary Filter can filter smaller than the cells of 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! Air Purifier Features: Air quality dust sensors automatically detect the built-in, automatic detection of the pollutant in the air. Air purification degree indication: digital display of the current indoor air quality, clean indicator by color change, it can display a deeper level of air quality of the current environment. Automatic Alarm: Set in the early effect filters, activated carbon filter, HEPA filter replacement indicator. Automatic mode: built-in smart chip, can be set to "manual, automatic, time, sensor" mode as needed. Automatic power-off: The machine set up automatic safety switch off and dumping off switch, simply open the front panel or dumping machine, the machine will automatically power off, stop working. Digital display: with a digital display of indoor air quality, indoor air quality reflect real-time, users easier and more convenient.
