Quick summary
The Xiaomi 3H at Rs 14,999 vs Sharp FP-J30M-B at Rs 8,490 pits smart connectivity against Japanese Plasmacluster technology.
The Xiaomi 3H is the better overall air purifier with superior CADR, larger coverage, and smart features. The Sharp makes sense only for small bedrooms under 300 sq ft where its Plasmacluster pathogen neutralization and 27W efficiency create a specialized value proposition the Xiaomi cannot match.

Buying tip
If your primary concern is seasonal flu and airborne infections rather than particulate pollution, the Sharp's Plasmacluster technology is clinically relevant - it actively deactivates viruses in the air. No HEPA filter, including the Xiaomi's, can neutralize pathogens; they only trap them. For health-focused families, this distinction matters.

Quick answers
Yes. The Xiaomi's 380 m3/hr CADR vs Sharp's 240 m3/hr means it filters nearly 60% more air per hour. For PM2.5 and particulate pollution, the Xiaomi is significantly more effective. The Sharp's advantage is in pathogen neutralization via Plasmacluster, not particle removal.
Sharp's Plasmacluster technology releases ions that attach to and deactivate airborne bacteria and viruses, verified by 30+ global testing laboratories. It does not kill viruses already on surfaces, but it reduces airborne pathogen concentration. This is a genuine, tested capability, not just marketing.
The Sharp at 27W vs Xiaomi's 38W costs roughly 30% less in electricity. Running 12 hours daily, the Sharp uses about Rs 80/month vs Rs 115/month for the Xiaomi. The difference is modest but adds up over years.
