not sure its working or not.. because colour sensor work uneven.
excellent buy. all features of high end air purifier present in this value for money product including HEPA filter,activated carbon filter,ionizer, UV filter and humidifier.
It has hepa filter, carbon filter , ion generator alike other filters. But it has humidifier too. It does not indicate the value of pollution but indicate s the level by 4 colors . Green indicating Good air quality. In Delhi During winters main culprits are dryness of air , smoke and allergic kind of pollen grains . Dry air causes itchyness in throat. Therefore humidifier is a must. It is therefore value for money deal. I purchased it for filtering out allergens (pollen and their strong smell) and induce humidity. So actual test of machine is due. It's a silent machine and there is no noise on night mode. UV and ionizer can be put on or off individually. Blue indicator in the image indicates somewhat polluted air. Built quality is okay.
