Buying tip
If your concern is seasonal flu and airborne illness in a small bedroom, the Sharp's Plasmacluster technology adds virus neutralization that no HEPA-only purifier can match. If your concern is general Delhi/Mumbai pollution particles and odors, the Coway's 4-stage filtration is more comprehensive. Match the purifier to your primary concern.

Quick answers
If your room is 300-400 sq ft, yes - the Sharp's 28 sq m coverage is insufficient. The Coway covers 38 sq m with higher CADR and 4-stage filtration. If your room is under 300 sq ft and pathogen neutralization matters, the Sharp's Plasmacluster technology at Rs 4,000 less is a valid choice.
They do different things. Plasmacluster actively neutralizes airborne pathogens using ions - something HEPA cannot do. Coway's 4-stage system traps a wider variety of pollutants including VOCs and odors. For pathogen concern, Sharp wins. For comprehensive air cleaning, Coway wins.
Sharp at 27W vs Coway at 43W. Running 12 hours daily, the Sharp costs about Rs 80/month vs Rs 130/month for the Coway. The annual electricity saving of Rs 600 partially offsets the Rs 4,000 price gap over time.
