NEW DELHI: Sales of air purifiers are witnessing a sharp jump as pollution levels worsen across the country, even as the onset of winter spurs demand for other seasonal appliances including room heaters, geysers and electric kettles. Air-purifier sales on Amazon doubled over the past week alone, while those across e-commerce platforms grew 1.4 times in Sept-Oct compared with the same period last year.Quick-commerce platforms, including Blinkit, Zepto and Instamart too, are seeing a sharp rise in demand, with consumers in Tier 2 cities adding to the growth momentum, analysts and industry experts told TOI.Daily sales of winter appliances on Q-commerce touched Rs 29 lakh in Oct, up 55% from Sept and 50% over Oct last year. Air purifiers led the month-on-month surge, with daily sales jumping 3.7x to Rs 9.6 lakh, while room-heater sales rose 1.6x to nearly Rs 10 lakh, data culled from 1DigitalStack, a market intelligence platform, said.The trend points to an early start to the seasonal buying cycle, with online sales expected to scale up further as temperatures dip. Typically, about 3 in 10 winter appliance sales are registered online.“We are projecting a robust 31% year-on-year growth for the winter appliance category – specifically geysers, room heaters and electric kettles across e-commerce platforms. This season’s surge is heavily catalyzed by the flagship annual festive sales on Amazon and Flipkart marketplaces, which have shifted consumer behaviour towards front-loading their winter utility purchases to maximise discounts,” Samiran Mathur, VP insights and strategy at 1DigitalStack said.The current demand in these appliances is just a fraction of the expected peak. Last year, the quick commerce winter appliance market multiplied 5.7x from Oct to Nov, eventually hitting a Jan peak that was nearly 10x the Oct baseline, the data said. “With the onset of winters, we are seeing air-purifier sales on Amazon.in growing 2x in the last week.

To serve immediate needs, we have expanded our air purifier selection on Amazon Now,” an Amazon India spokesperson said.
