Masks help outdoors, but indoors isn’t safe either. Dust, smoke, and trapped pollutants linger even with windows shut. That’s where a good air purifier matters. It doesn’t just freshen the air; it quietly filters what your eyes can’t see. But with so many models claiming “high efficiency,” the real test is in the details CADR rating, HEPA filter grade, room coverage, and how smartly it adapts to changing air quality. In a city where clean air is no longer a given, picking the right purifier isn’t about luxury it’s about survival with a bit of sense and science.

- What features should I look for when picking an air purifier for Delhi?+Look for a True HEPA filter (H13 or above), activated carbon for odor and chemical removal, CADR rating suitable for your room size, and smart features like real-time AQI display or automatic fan speed adjustment. Noise levels and energy efficiency are also important, especially for bedrooms.
- How do I know what size air purifier I need for my room?+Check the coverage area (in sq. ft or m²) listed by the manufacturer and compare it with your room size. For Delhi pollution, it’s better to choose a purifier rated slightly higher than your actual room size for faster and more thorough purification.
