Pitch Introduction
The Nano Clean Shark Tank India pitch featured one of the most scientifically advanced technologies seen in the tank during Season 2. Founder Prateek Sharma, a graduate of IIT Delhi, presented a compelling case for his company, Nano Clean Global, which utilizes cutting-edge nanotechnology to tackle India’s growing pollution crisis. With a vision to protect citizens from respiratory diseases like asthma and COPD, Prateek entered the tank seeking ₹80 Lakhs for 2% equity, valuing his manufacturing startup at a significant ₹40 Crores. However, the journey from a research lab to a sustainable consumer brand proved to be a challenging narrative for the Sharks to buy into.
Business Overview
Nano Clean is a biotechnology and manufacturing startup that specializes in nanofiber-based filtration solutions. The company’s primary mission is to provide affordable and effective protection against air pollutants, bacteria, and viruses. Unlike traditional bulky masks, Nano Clean’s flagship product, Naso95, is a discreet nasal filter that sticks to the nostrils, offering a 95% filtration efficiency against PM 2.5 particles. The technology is built on biocompatible polymers, ensuring that the materials are safe for human contact and entirely biodegradable, addressing environmental concerns associated with disposable masks.
Beyond air purification, the company has expanded its portfolio into the smoking cessation market with Cigibud. This product acts as a filter for cigarettes, utilizing the same nanofiber technology to gradually reduce the intake of harmful tar and nicotine. By offering three different grades of filtration (30%, 50%, and 80%), Nano Clean aims to help smokers quit through a systematic reduction therapy. Despite these innovations, the business faced a significant hurdle: transitioning from a high-demand pandemic-era mask manufacturer to a niche consumer health brand.
Product Details
The core of the Nano Clean offering is its patented nanofiber membrane. These fibers are 100 times thinner than a standard thread of cloth, creating a mesh so dense that even microscopic particles cannot pass through, yet porous enough to allow for easy breathing. The Naso95 nasal filter is marketed as the world’s smallest wearable air purifier. It is designed for comfort and can be worn for up to 12 hours. Additionally, their Cigibud product is the first of its kind to apply nanotechnology to cigarette filters, providing a physical barrier that reduces the toxicity of smoke without significantly altering the experience for the user.
Market Position
In a market flooded with standard N95 masks and electric air purifiers, Nano Clean positions itself as a scientific alternative. Its unique selling proposition (USP) lies in the portability and discretion of its products. While most people find masks uncomfortable for long-term use, the nasal strip offers a middle ground. However, the company faces stiff competition from established healthcare brands and a general decline in the public’s urgency regarding air filtration post-pandemic. Their presence in 250+ medical stores and on major platforms like Amazon gives them a physical and digital footprint, but maintaining consumer interest in a non-mandatory health accessory remains a hurdle.

Shark’s and Founder’s QnA
Where did you do your engineering and how did you get interested in this?
I have a background in engineering from IIT Delhi. I am a fourth-generation civil engineer. My mother has severe asthma and during heavy dust storms, she had a peculiar habit of covering her face with a scarf. I thought there should be a better treatment for it. I started working with professors in the textile department to develop this technology.
Can you explain how this nanofiber technology actually works?
Our filter is made of nano fibers where the threads are 100 times thinner than ordinary cloth. Even the smallest particle in the air cannot pass through it. We use a biocompatible polymer so it doesn’t harm you, and our patent covers how we keep the membranes together to ensure high efficiency and comfort.
Which specific pollutants are you blocking with the nasal filter?
We have two variants. One is for general air pollution and one for PM 2.5. This product is up to 95% efficient. In fact, for the size of viruses, our efficiency is around 97%. It blocks particles as small as 0.3 microns by 95%.
What is the Cigibud product and how does it help smokers?
Cigibud helps people get rid of cigarette addiction using nicotine replacement therapy. It reduces smoking harmful effects by filtering smoke in three grades: 30%, 50%, and 80%. After smoking through this filter once or twice, the user understands it is different from any other worldwide product.
What has been your revenue journey so far?
Till now, we have generated a total revenue of up to ₹15 Crores. We had a peak annual revenue of ₹7.6 Crores (during the pandemic), which then declined to ₹4.9 Crores, and last year it dropped to ₹1.1 Crores. Currently, we are doing about ₹5 Lakhs per month.
Why is the revenue declining so sharply?
A significant part of our previous business was manufacturing N95 masks using our technology when they weren’t available to the masses. Now, we are pivoting more toward our consumer-focused products like Naso95 and Cigibud, which we just launched recently in December.
Key Stats & Financials
At the time of the Nano Clean Shark Tank India pitch, the company presented a complex financial picture. While the lifetime revenue of ₹15 Crores was impressive for a deep-tech startup, the trajectory was concerning. The business had capitalized heavily on the N95 mask demand during the COVID-19 pandemic, reaching a peak turnover of ₹7.6 Crores. However, as the world moved away from universal masking, the company’s revenues plummeted to ₹1.1 Crores annually, with current monthly sales stagnating at just ₹5 Lakhs.

Business Potential and TAM
The business potential for Nano Clean Shark Tank India lies at the intersection of the air purifier market and the smoking cessation industry. The global air purifier market was valued at approximately $14 Billion in 2023 and is expected to grow as air quality worsens in developing nations. India, home to 14 of the world’s 20 most polluted cities, represents a massive Total Addressable Market (TAM). However, the challenge for Nano Clean is converting this environmental crisis into a consumer habit for wearable nasal filters, which are still viewed as unconventional.
Market Size Analysis
The Indian smoking cessation market is another significant opportunity, valued at over ₹800 Crores and growing at a CAGR of 12%. By offering a physical filter (Cigibud) rather than just gums or patches, Nano Clean enters a less crowded sub-segment of the nicotine replacement therapy (NRT) market. The broader respiratory care market in India, including treatments for asthma and COPD, is a multi-billion dollar industry where Nano Clean’s preventative technology could theoretically save billions in healthcare costs if adopted at scale.
Growth Opportunities
- Expansion into high-pollution industrial B2B sectors (factories, mining).
- Global export to other polluted metropolitan hubs in Southeast Asia.
- Strategic partnerships with oncology and pulmonary clinics for Cigibud.
- Development of AC-mounted nanofiber filters for home purification.

Marketing and Distribution Strategy
Nano Clean utilizes an omni-channel distribution strategy to reach its diverse customer base. While their technology is sophisticated, their marketing focuses on the simplicity of the “peel and stick” application for Naso95. They leverage digital platforms for direct-to-consumer sales, which currently account for 25% of their revenue. The remaining 75% is driven by a traditional B2B model, supplying to hospitals, clinics, and medical retailers.
Customer Acquisition
The company acquires customers primarily through search engine marketing (SEM) targeting keywords related to pollution and asthma. They also use “doctor detailing,” where medical representatives present the technology to ENTs and Pulmonologists, who then recommend the product to patients. This clinical validation is crucial for high-ticket items like Cigibud. However, the high Customer Acquisition Cost (CAC) for niche medical products has been a strain on their recent profitability.
Distribution Channels
- Direct-to-Consumer (D2C) via nanoclean.store.
- E-commerce marketplaces including Amazon and Apollo 24/7.
- Offline network of over 250 pharmacy stores across India.
- B2B institutional sales to hospitals and industrial plants.
Social Media and Content Strategy
On social media, Nano Clean focuses on educational content. They share electron microscope images of their nanofibers to prove the efficacy of the product. Their Instagram presence revolves around air quality index (AQI) alerts and health tips for smokers. While scientific, the content sometimes lacks the emotional hook needed for viral consumer growth, a point noted by the Sharks during the pitch.
Nano Clean Shark Tank Deal Outcome
Despite the innovative nature of the technology, the Nano Clean Shark Tank India pitch did not result in a deal. The Sharks were primarily concerned with the massive drop in revenue and the lack of a clear product-market fit for the consumer nasal strips. Amit Jain opted out because he found the product use case confusing. Aman Gupta followed suit, feeling the business lacked a strong consumer brand identity.
Namita Thapar and Anupam Mittal offered a “mirror” to the founder, suggesting that the current consumer products were too niche and likely to fail. They advised Prateek to pivot back to industrial B2B applications where the technology could be licensed or used in large-scale filtration systems rather than individual nose stickers. Peyush Bansal also declined, resulting in Nano Clean leaving the tank without funding.
| Shark | Offer Detail |
|---|---|
| Anupam Mittal | Out – Suggested pivoting to industrial B2B |
| Namita Thapar | Out – Believed product was not consumer-friendly |
| Peyush Bansal | Out – Skeptical of business model scalability |
| Amit Jain | Out – Did not understand the product utility |
| Final Decision | No Deal |
Nano Clean Post-Show Update
Following the Nano Clean Shark Tank India appearance, the company received significant media attention. According to reports by The Times of India, Nano Clean was recognized as one of the most scientific pitches of the season. While the immediate sales saw a temporary spike due to the “Shark Tank effect,” the company faced challenges in maintaining that momentum. Verified post-show updates for Nano Clean regarding new funding rounds or updated revenue figures are not yet available. We will update this section as reliable information is published.
Business Analysis & Lessons
The Nano Clean pitch serves as a classic example of a technology-heavy startup struggling to find its footing in the consumer goods (FMCG) space. Prateek Sharma successfully developed a world-class filtration material but struggled to package it into a product that consumers actually wanted to wear in public. The reliance on the pandemic-induced mask boom created a “false positive” in their revenue charts, masking the underlying difficulty of selling nasal strips as a lifestyle product.
For entrepreneurs, the lesson here is the importance of market validation over technical brilliance. A patent-protected, 95% efficient filter is only valuable if the delivery mechanism (the nose strip) is socially acceptable and convenient for the user. The Sharks’ advice to pivot toward B2B applications—such as air conditioning filters or industrial exhaust systems—highlights a strategic move from a low-margin, high-friction consumer sale to a high-volume industrial solution.
Key Takeaways
- Beware of Temporary Market Booms: Pandemic-driven sales do not always translate to long-term brand sustainability.
- Technology vs. Product: A great technology (nanofibers) needs a great product design (user-friendly application) to succeed in D2C.
- B2B vs. B2C: Some deep-tech innovations are better suited for industrial licensing than retail sales.
- The Importance of Momentum: A sharp decline in revenue (from ₹7.6 Crores to ₹1.1 Crores) is a major red flag for investors, regardless of the tech.
Pitch Conclusion
The Nano Clean Shark Tank India story is a testament to the brilliance of Indian engineering coming out of institutes like IIT Delhi. While Prateek Sharma did not walk away with a deal, the exposure highlighted the potential of nanotechnology in solving India’s environmental health issues.
