Quick answers

Frequently Asked Questions

Sharp FP-J30M vs Mi 4 Compact - is the Mi worth Rs 1,509 more?

The Mi Compact for most buyers. It offers app control, voice assistant, OLED display, H13 HEPA, and higher CADR. The Sharp is better only if Plasmacluster pathogen neutralization is your specific priority. For general Indian pollution, the Mi provides more features and better purification at the same price.

Does the Mi 4 Compact have anything like Plasmacluster?

No. The Mi uses conventional H13 HEPA filtration only. It traps particles mechanically but does not neutralize pathogens in the air. Plasmacluster's ion-based pathogen deactivation is unique to Sharp and cannot be replicated by HEPA filters. If this feature matters, only the Sharp offers it.

Which uses less electricity at the same price?

The Sharp at 27W uses 29% less power than the Mi at 38W. Running 12 hours daily, the Sharp costs about Rs 80/month vs Rs 115/month for the Mi. The Sharp's lower power consumption saves about Rs 420/year in electricity.
