How is the air quality in Mysore generally

For some time I've been thinking of doing a workation for a couple of months in Mysore. I follow this page which shows government AQI data, and Mysore is usually the cleanest among most Indian cities - [Mysore Air Quality Index (AQI) and India Air Pollution | IQAir](https://www.iqair.com/in-en/india/karnataka/mysore) . However, today I was talking to a friend from France who has lived in Mysore 20 years ago for 3 years. She said that she went back 10 years later, and found that the city had become a bit polluted and the beautiful outskirts where there used to be a lot of nature was now looking like a concrete dominated area. Then she went back in December this year and she found it really crowded and polluted. She even said she could not see Chamundi Hill while she had always lived in the same area in every visit earlier and loved the view of the hill. This time there was too much pollution to have a clear view of the hill. Is this true? I wonder what people living in Mysore think, both about the current levels of pollution and the kind of growth in crowds and pollution she is describing.
