Editor's analysis
A hand-written take on how these two compare in the real world.
India's most affordable vs Sweden's most efficient: KENT Aura HEPA at Rs 8,999 vs Blueair Blue Pure 411 at Rs 16,999. The Rs 8,000 gap is significant at this price range. The Blueair justifies it with 350 vs 180 m3/hr CADR (nearly double), 38 vs 25 sq m coverage, 17 vs 40 dB noise, and 10W vs 60W power. The KENT's only argument is its sub-Rs 10,000 price and KENT's service network. On every performance metric, the Blueair is dramatically superior.

Buying tip
The electricity cost difference is dramatic: KENT at 60W costs roughly Rs 180/month running 12 hours daily, while the Blueair at 10W costs Rs 25/month. The Blueair saves Rs 155/month - that is Rs 1,860/year in electricity savings. Over 5 years, electricity savings alone (Rs 9,300) exceed the Rs 8,000 price premium.

Quick answers
Only in price and service network accessibility. On every performance metric - CADR, coverage, noise, power consumption, filtration technology, design, portability - the Blueair is substantially better. The KENT is a basic entry-level purifier; the Blueair is a premium engineered device.
In performance, the Blueair delivers roughly 2x the CADR, 1.5x the coverage, runs 6x quieter, and uses 6x less electricity. The performance improvement exceeds the price ratio. Combined with electricity savings of Rs 1,860/year, the Blueair actually becomes cheaper to own over 5 years.
Short-term budget: KENT at Rs 8,999. Long-term budget: Blueair, because lower electricity costs (Rs 155/month savings), longer filter life, and better performance per watt make it cheaper to own over time despite the higher purchase price.
