Founded in 2020 by Ravi Kaushik and joined later by Abhimanyu Kumar, Airth’s goal is to make clean air accessible to every home in India. Priced at just ₹3,000, the product transforms ordinary air conditioners into powerful air purifiers while cutting AC maintenance costs. Its modular design makes it equally effective year-round, adapting to summer and winter needs seamlessly.

India faces a significant air quality crisis, with 12 of the 15 most polluted cities globally located within its borders. While outdoor pollution garners attention, AC systems often circulate external pollutants indoors, compromising indoor air quality.

Airth’s solution addresses this issue head-on. By combining HEPA technology with a unique germ-destroying coating, the filter not only traps fine particles but actively deactivates viruses and bacteria. It’s a simple installation process—taking just two minutes—making clean air a reality for over 25,000 homes already using this product.

At the heart of Airth’s innovation lies its proprietary Airth Coating, a germ-killing filter powered by ingredients like polyphenols and polycationic polymers commonly found in green tea. These components rupture microbes through precise molecular binding.

When Airth pitched its vision to the Sharks, the product’s potential to improve indoor air quality stood out. However, concerns about the equity structure and scalability created heated discussions.

• Shark Vineeta Singh: ₹60 Lakhs for 2% equity.
• Shark Anupam Mittal: ₹1 Crore for 5%, wanting a stake in the growing category.
• Shark Varun Alagh: Opted out due to concerns about scaling the business side.
• Shark Peyush Bansal: Praised the idea but bowed out, citing issues with the capital table.
• Shark Aman Gupta: Matched Anupam’s offer of ₹1 Crore for 5%.

The founders countered with ₹96 Lakhs for 3% equity, valuing the business at ₹32 Crores. After further deliberation, Aman and Vineeta teamed up to offer ₹96 Lakhs for 4%. Anupam revised his offer to ₹2 Crores for 10%. Finally, Aman and Vineeta adjusted their offer to ₹96 Lakhs for 3.7%, valuing the business at ₹27.3 Crores, which the founders accepted.

While the product’s impact was undeniable, the Sharks raised several concerns:

1. Scalability Issues: Who would drive the business side of scaling?
2. Capital Structure: Complex equity ownership made some Sharks hesitant.
3. Marketing Strategy: Heavy reliance on Amazon left room for diversifying revenue streams.

With the Shark Tank funding, Airth plans to:

• Expand Product Range: Launch car AC filters and large-scale solutions for buildings.
• Grow E-commerce Channels: Boost direct website sales to reduce platform dependency.
• Enhance Marketing Efforts: Invest in reaching untapped markets across India and beyond.

Airth’s ambition to create a new category in air purification could make them a dominant player in the market.

While challenges remain in scaling and diversifying revenue, the ₹96 Lakhs funding and Shark support will provide the momentum Airth needs to expand its footprint. As indoor air quality becomes a growing concern globally, Airth’s innovation could set a new standard for healthier living spaces.
