Aerflo fans + Nuance can save about ₹37,000 every year on these 10 fans.
That is nearly two-thirds off the bill, and twice what you save by changing to Aerflo fans alone.
Based on 10 fans running 13 hours a day, 300 days a year, ₹8 per unit of electricity, with people in the room about half the time. Your savings will depend on your own fans, hours and electricity rate.
