Buying tip
The Mi Compact's app tells you exactly when to replace filters based on actual usage and air quality data - not just a timer. This data-driven approach can extend filter life beyond the Coway's simple timer-based indicator, potentially saving Rs 500-1,000 per year in filter costs despite similar filter prices.

Frequently Asked Questions
Should I pay Rs 4,000 more for Coway over Mi Air Purifier 4 Compact?
Only if quiet bedroom operation is essential - the Coway's 22 dB vs Mi's 33 dB is a noticeable difference for light sleepers. The Mi Compact offers H13 HEPA (higher grade than standard), app control, voice assistant, and OLED display. For most buyers, the Mi Compact's smart features at Rs 4,000 less are the better deal.
Which has better air quality monitoring - Coway LED or Mi app?
The Mi Compact wins decisively. Its particulate sensor feeds data to the Mi Home app showing real-time PM2.5 readings, air quality history, and filter life. The Coway has only a basic LED color indicator (green/yellow/red) with no numerical data or history tracking.
Can the Mi Compact's filtration match Coway's 4-stage system?
The Mi Compact uses H13 True HEPA which captures finer particles than the Coway's Green True HEPA. However, the Coway's 4-stage system includes dedicated activated carbon and deodorization layers for odors and VOCs. For particles, the Mi is technically better. For odors, the Coway is more thorough.
