Pitch Introduction
The airth Shark Tank India pitch introduced a high-tech solution to one of India’s most pressing environmental challenges: indoor air pollution. Founders Ravi Kaushik and Abhimanyu Kumar entered the tank with a compelling proposition—turning every existing split air conditioner into a high-grade air purifier. While traditional purifiers often struggle with adoption due to space and cost, airth integrates seamlessly into the household’s existing cooling infrastructure. The founders, hailing from Delhi, showcased a level of technical depth and market readiness that immediately sparked a bidding war among the Sharks. With a focus on scientific validation and a clear growth trajectory, the pitch highlighted how a niche hardware innovation can scale into a significant consumer brand.
Business Overview
airth operates at the intersection of home lifestyle and health technology. The company identifies a critical flaw in modern urban living: while we spend 90% of our time indoors, the air inside is often more polluted than outside because split ACs simply recirculate existing air without filtering out microscopic toxins. airth solves this by providing a filter that sits atop the AC unit, capturing pollutants before the air is cooled and distributed.
Since its launch, the brand has focused on creating a new category in the eCommerce landscape. Unlike standard HEPA filters that can drop AC pressure and increase electricity bills, airth utilizes a specialized electrostatic coating. This allows for high filtration efficiency without taxing the AC’s motor, ensuring that the user’s electricity bill remains virtually unchanged while the air quality improves drastically.
Product Details
The primary product is a modular air purifier designed specifically for split air conditioners. It comes in two variants: the Summer version (focused on purification during cooling) and the Winter version (which includes a fan mode for year-round use). The core technology is a patented coating developed with support from IISc Bangalore, which is capable of destroying microorganisms rather than just trapping them.
The device is constructed with a flexible foam base to accommodate the different curvatures of various AC brands. It uses magnetic strips for a tool-free installation that takes less than two minutes. The filter typically lasts between 8 to 12 months, after which the consumer can purchase a replacement filter, creating a recurring revenue model for the business.
Market Position
airth positions itself as an affordable alternative to standalone air purifiers. While a high-end standalone purifier can cost anywhere from ₹15,000 to ₹40,000 and occupy floor space, the airth solution costs approximately ₹2,200 to ₹3,200. This price point makes clean air accessible to middle-class households who already own an AC.
The competitive advantage lies in the founders’ academic pedigree and their intellectual property. With a 15-year exclusive license for their core coating technology and multiple utility patents filed, they have created a significant barrier to entry for generic competitors. Their market position is further strengthened by their IIT Kanpur and IIT Delhi testing certifications, which build consumer trust in a category often plagued by “snake oil” claims.

Shark’s and Founder’s QnA
What exactly is the problem with indoor air and split ACs?
Sharks, the air outside comes in and recirculates in your AC. You think you’re safe, but you’re actually breathing deadly, toxic air. We turn your ordinary AC into a Super AC. Our device sits like a crown on top and filters 30 grams of dust—that’s four teaspoons—from entering your lungs every year.
Does this increase the electricity bill of the consumer?
It increases the bill by only 1% to 3%, which is about 30 to 45 watts. This is much less than running a separate standalone air purifier which can consume up to 400 watts. We use electrostatic coating to keep the pressure drop low so the AC doesn’t work harder.
What is the equity split between you two?
I (Ravi) hold 64% and Abhimanyu holds 2%. The rest is with our early investors from London, IIT Kanpur, and our manufacturers. Abhimanyu joined later, but he is my right-hand man. I am happy to increase his equity to 50-50 in the future based on his contribution.
How are your sales looking currently?
In the financial year 2023-24, we closed at ₹2.1 Crores. This year, in just the first six months, we have already done ₹2.2 Crores. Last month we did ₹44 Lakhs, and in just the first 9 days of this month, we hit ₹40 Lakhs. We are on track to close this year at ₹6 Crores to ₹7 Crores.
Who is buying this? Is it just people in polluted Delhi?
Interestingly, Bangalore is one of our top five cities. People there buy it because of pollen and sinus issues. Some customers buy it because they are tired of cleaning their internal AC filters every month. It’s not just about pollution; it’s about hygiene and health.
What is your unit economics on a ₹2,200 product?
Our COGS is around ₹620. After GST and platform fees, our Gross Margin is 67%. Our Customer Acquisition Cost (CAC) is about ₹300. After all costs including logistics and fixed expenses, we make a profit of about ₹200 per unit, which is an 11% EBITDA profit.

Business Potential and TAM
The potential for airth is massive, given that air pollution is no longer a seasonal problem restricted to Northern India. The global air purifier market is valued at over $15 Billion and is growing at a double-digit CAGR. In India alone, the AC market is expanding rapidly, with millions of new split AC units installed every year. By piggybacking on this existing infrastructure, airth avoids the need to convince users to buy a new machine; they simply upgrade what they already own.
Market Size Analysis
The Total Addressable Market (TAM) for airth includes every household with a split air conditioner. Globally, there are over 2 Billion split ACs. In India, as urban temperatures rise and air quality declines, the AC has become a necessity rather than a luxury. Even if the brand captures just 1% of the Indian AC user base, the revenue potential exceeds ₹500 Crores annually, especially with the high replacement frequency of filters.
Growth Opportunities
- Expansion into Centralized AC systems for commercial buildings and offices.
- Development of specialized filters for Car AC units to tackle commute pollution.
- International expansion into Southeast Asia and Middle Eastern markets with high AC usage.
- B2B partnerships with real estate developers to include airth as a standard feature in new apartments.

Marketing and Distribution Strategy
The company’s go-to-market strategy is heavily focused on digital discovery. Since their product solves a problem people are already searching for—pollution and AC maintenance—they have successfully utilized performance marketing to drive high intent traffic to their sales channels.
Customer Acquisition
airth acquires customers primarily through Amazon and their own website. Their CAC of ₹300 is remarkably low for a health-tech product, largely because the product’s visual demo is highly shareable and educational. They use 20% of their net revenue for marketing, which is surprisingly efficient for a brand that is building a completely new product category.
Distribution Channels
- Amazon: Accounts for 70-80% of total sales volume.
- Direct-to-Consumer (D2C) Website: For brand building and high-margin seasonal bundles.
- B2B Channels: Supplying to hospitals and clinics through specialized medical distributors.
- Quick Commerce: Potential future roadmap for filter replacements in major cities.
Social Media and Content Strategy
Their content strategy revolves around the “Visible Proof” of pollution. By showing the dust captured by their filters versus standard AC mesh filters, they create a “gross-out” factor that encourages purchase. They also leverage the IIT Bombay pedigree in their communications to establish scientific authority.
airth Shark Tank Deal Outcome
The negotiation for airth was one of the most intense of Season 4. Anupam Mittal was highly aggressive, offering ₹2 Crores to solve all their funding problems, but he demanded 10% equity. Peyush Bansal and Varun Dua stayed out due to concerns over the cap table and operational scaling. Eventually, the founders chose to go with the duo of Aman Gupta and Vineeta Singh.
| Shark | Offer Detail |
|---|---|
| Vineeta Singh | ₹60 Lakhs for 2% (Original Offer) |
| Anupam Mittal | ₹1 Crore for 5% or ₹2 Crores for 10% |
| Aman Gupta | Matched Anupam’s ₹1 Crore for 5% |
| Peyush Bansal | Out (Conviction issues on management) |
| Final Decision | ₹1 Crore for 3.7% Equity with Aman and Vineeta |
airth Post-Show Update
According to Times of India, the company saw an immediate surge in interest following the episode. The founders reported that the Sharks have been proactive in helping them with distribution and design. As reported by The Indian Express, Ravi Kaushik noted that the selection process was rigorous but the exposure has been transformative for their brand awareness. Verified post-show revenue figures for airth indicate they are successfully scaling toward their ₹7 Crore target for the current fiscal year.
Business Analysis & Lessons
The airth business model is a textbook example of “Infrastructure Hacking.” By creating a product that enhances an existing high-value appliance (the AC), they bypass the biggest hurdle in consumer hardware: getting people to clear space for a new machine. Their pitch was highly successful because it balanced deep technical credibility with simple, effective demonstrations that even a non-technical consumer could understand.
However, the pitch also highlighted a common startup struggle: the uneven equity split between founders. Ravi’s 64% versus Abhimanyu’s 2% was a point of concern for several Sharks. This serves as a lesson for early-stage entrepreneurs to structure their cap tables in a way that ensures long-term motivation for all key team members before seeking institutional capital.
Key Takeaways
- Lesson 1: Solve for Habit – airth succeeded because it didn’t ask users to change their behavior; they already use ACs.
- Lesson 2: Efficiency is Sales – By ensuring only a 1-3% increase in electricity, they removed a major barrier to purchase.
- Lesson 3: Validation is Key – Having IIT and IISc certifications gave the Sharks the confidence to invest in a crowded market.
- Lesson 4: Cap Table Health – Unbalanced equity can scare away investors who worry about the long-term commitment of secondary founders.
Pitch Conclusion
The airth Shark Tank India pitch concluded with a hard-fought deal that validated the founders’ years of research. By securing ₹1 Crore from Aman Gupta and Vineeta Singh, the company is now well-positioned to dominate the affordable air purification market in India.
