As Delhi's air quality index deteriorates, car manufacturers are incorporating air purifiers into models under Rs 15 lakh. Features like PM2.5 filters and AQI displays aim to provide cleaner cabin air for commuters. Notable models include the Maruti Suzuki Victoris, Skoda Kushaq Onyx Edition, and Hyundai Creta, offering solutions for urban families concerned about smog and pollution during their drives.
