Who Should Buy Which?
6 buyer profiles — matched to the brand that actually wins their use case
Bedroom install — silent night mode essential
28 dB at Speed 1 + sleep mode timer. Crompton's 30 dB is noticeable in a quiet room after midnight.
Smart home user — Alexa / Google Home integration
Native IoT on standard SKUs; Crompton requires a ₹500 premium smart variant that is harder to find.
Tier-2 or Tier-3 city buyer
1,200+ service points mean a technician visit won't require a courier. Atomberg service is still metro-heavy.
Multi-room rental property (5+ fans)
Lower per-unit price (₹2,700 vs ₹3,100) saves ₹2,000+ across a flat. Warranty length matters less for rentals.
Large open hall or living room (18×16 ft+)
240 CMM vs 230 CMM — that 4% airflow edge is felt in larger volumes. Enzel 1400mm sweep is the exception.
Long-term owner who hates repair hassle
5-year comprehensive warranty vs Crompton's 2+1. If anything fails, Atomberg covers it without argument for 5 summers.
