New Delhi: Getting an efficient air purifier at a price less than Rs 15,000 has become a necessity for Indian households with varying temperatures of air quality
in the big cities. As the pollution rate increases seasonally, together with the increasing concerns of indoor health, the need to have effective but inexpensive systems of purification has become rampant.
Here are the top five air purifiers that provide the best price/performance/feature balance. These models are designed to fit the needs of rooms of various sizes and applications with advanced HEPA filtration, high CADR ratings, smart app integration, and low noise levels.
