Mann-Filter FC 301 Car Air Purifier Portable Car Air PurifierBlack

I have been using the purifier in Mumbai for the past one month and it is problem free and effective. The build quality is good. The air quality indicator has three colours. They seem to be responding to the quality of air. I have used this in January which is the dirtiest month for Mumbai. I travel for two hours every day and the purifier is green most of the time. I have corroborated with the AQI app called Safar which gives the pollution levels in different areas. When the quality of the air worsens it usually turns yellow or red - this is specially around Vashi and Wadala. The purifier cleans odours in seconds, so one does not have to smell the stink of mumbai. I have less severe asthma since I have started using this one in the car and a Philips at home.
