Crystal actually being good air purifier HJR-8022, six core technologies, strong landing purification: 3 5 heavy layer filter layer filters purify 3: electrostatic dust filters, granular activated carbon filter, HEPA filter 5 heavy cleanup : HEPA filter ensures efficient pollen, dust mites, mold, PM2.5 and other filtration rate of more than 99%; activated carbon filter containing activated carbon is mainly composed of carbon-based materials as raw materials, high temperature carbonization and activation system obtained adsorbent. Contains a lot of microporous activated carbon with a large surface area, high adsorption of volatile organic compounds, secondhand smoke, dust particles; under the action of light, have a strong catalytic degradation function: it can effectively degrade toxic gases in the air; photocatalyst filter can effectively kill a variety of bacteria, fungi and bacteria can release a toxin and safe disposal or; decoration pollution dispel harmful gases to produce water and carbon dioxide photocatalyst must be used in conjunction with the UV lamp, colorless anion anion tasteless gas ions in the air a negative charge, it was the negative ions is called "air vitamin" and that it is like vitamin food, like the human body and other biological activities of life have an important impact, and some even think aeroanion and longevity, called "longevity factor." Number of negative ions in the air by the impact of different geographical conditions particularity content. Parks, suburban fields, beach, lakes, waterfalls and forests near the content more. So, when people enter these fields venues mind fresh, comfortable breathing. Make two of the bacterial protein reversed, leaving the bacterial viability decline or death. 6 core technologies: LED color display; active sterilization technology; filter replacement reminder; efficient removal of PM2.5; automatic mode; triple screen (in addition to formaldehyde up to 98%, PM2.5 removal rate is 99% ) Rated power: 58W Rated voltage: 220V 50HZ Application area: 30M2 CADR values: 300M3 / h Main Material: ABS Color: red, green formaldehyde removal rate: 96.2% of bacteria removal rate: 97.6% particle removal rate: 0.3um 99.9% Products Dimensions: 329 * 205 * 569mm sound noise: <35db Weight: 7.2kg
