Editor's analysis

The expert read

A hand-written take on how these two compare in the real world.

A Xiaomi vs Xiaomi matchup: the older 3H at Rs 14,999 vs the newer 4 Compact at Rs 9,999. Both have Mi Home app control, voice assistant support, and True HEPA filtration. The 3H is bigger - 380 m3/hr CADR and 45 sq m coverage vs the Compact's 260 m3/hr and 32 sq m. The Compact is Rs 5,000 cheaper with the newer H13 grade filter. If you are already in the Xiaomi ecosystem, this is purely about room size and budget.

If your room is under 350 sq ft, the Mi 4 Compact saves Rs 5,000 while delivering the same smart experience with a newer H13 filter grade. For rooms above 350 sq ft, spend the extra Rs 5,000 on the 3H for its 46% higher CADR and larger coverage. Same ecosystem, same app, just different room size optimization.

Decision guide

Which one should you buy?

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

Choose

Mi Air Purifier 4 Compact

If you want

  • Your room is larger than 350 sq ft - the 45 sq m coverage is needed
  • You want maximum CADR of 380 m3/hr for severe pollution days
  • Slightly bigger display and more prominent design suit your preference
  • You want the highest air throughput in the Xiaomi purifier range

Choose

Xiaomi Air Purifier 3H

If you want

  • Your rooms are under 350 sq ft and you want to save Rs 5,000
  • Newer H13 grade True HEPA filter is a marginal advantage
  • More compact and lighter design for smaller apartments
  • You want the best-value smart air purifier under Rs 10,000

Buying tip

Both connect to the same Mi Home app with identical features - scheduling, air quality monitoring, voice control. The key difference is purification power. If you plan to move the purifier between rooms, the smaller Compact at 4.2 kg is more portable, but the 3H's higher CADR means it handles your worst-pollution room better.

Quick answers

Frequently Asked Questions

Should I buy Xiaomi 3H or the newer Mi 4 Compact?

Buy the 3H if your room exceeds 350 sq ft or you live in a heavily polluted area where the 380 m3/hr CADR makes a noticeable difference. Buy the 4 Compact if your rooms are under 350 sq ft and you want to save Rs 5,000 while getting the same smart features and newer H13 filter.

Is the Mi 4 Compact's H13 filter better than the 3H's True HEPA?

Yes, technically. H13 captures 99.95% of particles at 0.1 microns, while the 3H's True HEPA captures 99.97% at the larger 0.3 microns. For ultra-fine particles, the Compact's filter is marginally superior. In real-world Indian pollution (mostly PM2.5 and above), the difference is negligible.

Do both Xiaomi purifiers work with the same app and accessories?

Both use the Mi Home app with identical smart features. However, their filters are NOT interchangeable - the 3H uses a larger cylindrical filter while the 4 Compact uses a smaller one. Replacement filter costs are similar at Rs 2,500-3,000 each.
