Overview

Following Diwali, Delhi-NCR experienced a severe pollution spike, driving a massive surge in demand for air purifiers and clean-air devices. E-commerce platforms reported multi-fold increases in sales, benefiting climate-tech startups like Qubo, Karban Envirotech, Atovio, and Praan. These companies are innovating with niche products and recurring revenue models, though the sector faces challenges in securing venture capital due to long investment cycles.

Delhi Pollution Surge Post-Diwali Sparks Climate-Tech Boom: Air Purifier Sales Skyrocket

Delhi's air quality dropped to 'severe' levels post-Diwali due to firecracker fumes mixing with winter stagnation, leading to an annual surge in demand for pollution-control products.

E-commerce giants reported significant sales increases: Amazon saw a 5x jump in air purifier sales across India and a 20x surge specifically in Delhi-NCR, with premium models growing over 150% year-on-year. Flipkart observed an 8x rise in Delhi-NCR purifier demand, while its quick-commerce arm experienced a nearly 12x jump. Quick-commerce platforms like Instamart reported close to a 10x surge in purifiers and N95 masks, predominantly from North India.

This consumer demand is fueling specialized climate-tech startups that are carving out specific segments within the clean-air market.

Key Startups and Their Innovations:

  • Qubo (Hero Electronix-backed): Offers smart purifiers priced between ₹8,000 to ₹20,000, with an average selling price of ₹10,000. They sold over 30,000 units in the current financial year and expect to reach 50,000 by FY25, driven by a post-Diwali uptick. Their niche car purifiers are selling about 100 units daily. Qubo relies on filter replacements for recurring revenue, using automated alerts for customers.
  • Karban Envirotech: Diversifies vertically by combining fans, purifiers, and lighting in single units to ensure year-round sales. Their devices range from ₹15,000 to ₹30,000, with an average order value of ₹20,000. Recurring revenue comes from filter replacements, AMCs, and installation services. The company raised $1.07 million last year and plans to seek more funding.
  • Atovio: A Gurugram-based startup focusing on wearable air purifiers, which create a personal clean-air zone. Priced at ₹3,500 each, they have sold around 18,000 units since launching in late 2024. Demand has seen a massive spike, with last week's numbers 50x higher than the first week of September. Atovio is currently bootstrapped.
  • Praan: A deep-tech company that initially developed filterless, industrial-grade purification systems for factories like Tata Steel and Nestlé. This year, they pivoted to homes and offices, selling about 150 units this month alone (matching all of last year's sales). Their products currently average ₹60,000 but aim to reduce the price to ₹30,000 next year. Praan has secured US backing after facing difficulties raising capital in India.

Challenges and Future Trends:

Despite the surge in consumer demand, venture investment in India's climate tech sector remains thin. Founders note that while recurring revenues from filters and services offer repeatability, significant challenges persist. Sumanta Biswas of CUTS International points out that less than 3% of approximately 800 viable climate-tech startups in India have raised Series B funding or beyond, indicating a serious scaling gap. Factors like large upfront capital requirements, long regulatory lead times, and dependence on government adoption make many venture capitalists wary.

However, adaptation products, offering shorter payback cycles and clear business models, are gaining traction over long-horizon prevention bets. Entrepreneurs are expected to focus on micro-segments like hyperlocal climate services and personal air-tech, which offer leaner models and faster returns.

Impact

This news directly impacts Indian consumers by highlighting immediate solutions and available products for air pollution, driven by a predictable annual event. For investors, it signals a burgeoning sector within climate technology, particularly in adaptation products, that offers sellable, short-cycle monetization. The predictable seasonal demand creates a unique business cycle, but significant challenges remain in scaling and securing venture capital due to the nature of the industry. The growth of these niche startups could lead to increased competition and innovation in the clean-air market.
