Decision guide

Which one should you buy?

Pick the one that matches your priorities, not the spec sheet.

Choose

Coway Airmega 150

If you want

  • Your room is 300-400 sq ft requiring the 38 sq m coverage
  • Comprehensive 4-stage filtration for particles, odors, and gases
  • Higher 250 m3/hr CADR for faster air cleaning in pollution
  • Korean Coway brand with dedicated air purifier expertise

Choose

Sharp FP-J30M-B

If you want

  • Plasmacluster Ion technology for bacteria and virus neutralization
  • Your bedroom is under 300 sq ft and the 28 sq m coverage suffices
  • Ultra-low 27W power consumption for energy-conscious use
  • Save Rs 4,000 and get unique Japanese pathogen neutralization

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

Frequently Asked Questions

Is Coway Airmega 150 worth Rs 4,000 more than Sharp FP-J30M?

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.

Does Sharp Plasmacluster work better than Coway's 4-stage filtration?

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.

Which uses less electricity - Coway or Sharp?

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.
