This Prodigy Has Constructed Considered one of World’s Most Superior Air Purification Tech


Angad Daryani, the 25-year-old founding father of Praan, Inc., a deep-tech startup based mostly out of Mumbai, is a part of a technology that grew up with a actuality of a bleak future—one plagued with air pollution and local weather change. 

“Earlier generations grew up with the promise of an thrilling future the place For those who labored onerous and constructed a profession, [the expectation was that] the longer term could be nice. However our technology grew up with the fact of local weather change, animal extinction, and extreme air and water air pollution. Since I used to be about six years outdated and realized about this stuff on Nationwide Geographic, this discomfort a couple of bleak future has stayed with me,” explains Angad, in a dialog with The Higher India

Fixing real-world issues has all the time excited him. A toddler prodigy from Mumbai, Angad constructed his first robotic and a solar-powered boat at age 8, moreover constructing a homegrown 3D printer by 13 and an e-reader (Digital Brailler) for the visually-challenged by 15. He briefly dropped out of the education system due to his disillusionment with the rote learning-based state board system.  

“I discovered faculty complicated. Whereas I used to be doing effectively academically, the rote-based schooling didn’t construct my fundamentals which might change into apparent once I’d compete in Olympiads and wrestle to unravel issues. Similtaneously a interest, I used to be constructing all these advanced engineering initiatives at residence alone just by watching movies or studying books. Once I dropped out of college, my dad and mom employed a tutor who would train me all the identical issues as different highschool college students, whereas rebuilding my fundamentals. Since I didn’t have homework and was fixing issues whereas studying the matters, I had a variety of free time to deal with my scientific hobbies.” he recollects. 

Throughout this time, when Angad was round 14 years outdated, he wrote an e mail to Professor Ramesh Raskar, an Indian-born professor on the Massachusetts Institute of Know-how (MIT). Presently, he’s an Affiliate Professor of media arts and sciences on the famend MIT Media Lab and an advisor to famend know-how giants like Google and Apple.

“It’s amusing wanting again at my ignorance, however I wrote to him saying, ‘You’re an Indian professor and MIT brings vivid younger college students from all over the world to its campus, so why not carry on somebody from India?’ Extremely, he wrote again virtually instantly and I ended up working with MIT by way of their India Initiative for 2 years constructing know-how that might resolve real-world issues in well being tech. Even until at the present time, Professor Raskar stays supportive of my journey and has been an unbelievable mentor” he recollects. 

After these two years working with MIT, he went again to an IB (Worldwide Baccalaureate) faculty, following which he studied electrical engineering on the prestigious Georgia Institute of Know-how (Georgia Tech). It was throughout his time in school when he determined to behave on the rising downside of air air pollution and started growing options for it.  

Right this moment, his startup has constructed one of many “world’s most superior air purification applied sciences” utilizing a novel mixture {of electrical} cost dispersion and airflow optimization-based processes – permitting particles to be charged and creating electrical fields that transfer the particles to a set chamber. Angad mixed his background in electrical engineering, product design, IoT, course of engineering, and manufacturing to create an entire new class of air purifiers. 

Briefly, his resolution works by a community of air purifying models that may clear air inside giant areas like manufacturing unit flooring in simply minutes by mapping how the air pollution is flowing on the store ground after which strategically inserting the air purifiers to seize that air pollution. For instance, Praan’s newest product referred to as the MK II (‘Mach 2’) has a excessive purification price of 1300 cubic ft per minute. 


Impressed by sickness 

Rising up in Mumbai, Angad suffered from bronchial asthma. Each winter, notably in the course of the festive season, he would endure respiration difficulties as a consequence of excessive air air pollution and his household must depart the town.  

“With bronchial asthma and excessive mud ranges within the metropolis, I might wrestle to play soccer. I couldn’t run correctly as a result of my stamina would take a success and I might cough continually. However this was a actuality for lots of people residing round me. Right this moment, whereas I can transfer to a rustic with a cleaner atmosphere, I can’t anticipate my household and pals to do the identical. I couldn’t see them breathe this poisonous air every single day and this is the reason discovering an answer was so vital to me,” recollects Angad. 

In 2017, simply earlier than he started his sophomore 12 months at Georgia Tech, he started engaged on options for city air air pollution however this got here with some actual challenges.  

“If I used Georgia Tech’s infrastructure to construct my resolution, as per the clauses, they might personal all of the mental property. Because of this, I wouldn’t have the liberty to commercialise it as per evolving necessities. And therefore, commercially, we didn’t have entry to any of their labs. Additionally, because of my visa standing, I legally couldn’t register an organization and begin a enterprise with a co-founder there whereas being a university pupil,” he recollects.  

“And the reality about constructing air purification know-how is that it’s not simply the air purifier or the sensor you’re constructing, however you’re additionally constructing the infrastructure to check it in numerous wind, temperature, humidity, and air pollution circumstances. Given the dearth of monetary assets in the course of the bootstrap section, it was fairly onerous to construct a secure take a look at chamber that might work in all these totally different circumstances, present correct and dependable knowledge and permit you to take a look at with all totally different supplies of mud, gases and pollution,” provides Angad.  

Because of this, Angad began constructing the prototypes of those filterless purification methods based mostly on physics ideas out of his house room close to Georgia Tech the place fundamental traits could possibly be inspected visually. 

In response to this detailed description on Praan’s web site, “He would carry the prototype for two miles a number of occasions each week from his house to the on-campus makerspace to construct the earliest variations of a filterless air purification system. The system first began with a paint-bucket prototype after which made it to a metal ducting system model.” 

“As he continued to work on it, an increasing number of college students round campus would discover him strolling throughout the garden with this 5ft-tall metallic construction which appeared like a jet engine. Out of curiosity, they might speak to him,” it provides. 

A few weeks later, nevertheless, CNN reached out to him to interview for his or her ‘Tomorrow’s Hero’ collection. Following discussions over e mail, they got here all the way down to the Georgia Tech campus and shot a video with him the place they mentioned his mission, method and the know-how he was constructing to handle city air air pollution. CNN ultimately recorded and revealed this text and video which went viral very quickly. 

It’s vital to notice, nevertheless, that Angad wasn’t initially concerned about constructing your typical indoor air purifiers that you would be able to set up at residence.  

“Regardless of the business enchantment, I resisted growing a standard indoor air purifying system. I used to be not occupied with the highest 1% who can afford a Dyson however that baby who walks to highschool every single day or a manufacturing unit employee inhaling poisonous air throughout his/her shifts. My goal was to search out one thing that may be performed for big areas,” he says.  

“One other vital aspect was to not contain filters. If I hold a filter-based air air purifier at a big house in Delhi in the course of the winter one must change the filter each hour. I needed to construct a filterless system, which suggests no recurring value of possession in these giant areas,” he provides.

Energy of volunteers

A few months after his look on CNN, Angad returned to India for the summer time the place he continued to work on prototyping the units and testing them in India. 

As the Praan web site notes, “Since this venture was totally bootstrapped with no exterior financing, all of the prototyping was performed with off-the-shelf elements and built-in Angad’s bed room and terrace in Mumbai, every prototype was hand constructed, reduce, glued, soldered, and examined outdoor. Throughout this course of, he stored posting photos of his progress on the web.” 

The reason goes on so as to add, “Deeptech was nonetheless new in India and therefore the provision of threat capital was bleak. So Angad needed to bootstrap the venture and noticed 30 extra volunteers be part of him in his mission as he returned to Atlanta within the Fall 2018. This group was basically attempting to determine if filterless air purification utilizing chilly plasma know-how was doable and was alternatively additionally experimenting with bioengineering methods for purifying air in cities.”

Since his group didn’t have an workplace or entry to capital, all experimenting of the core tech was performed in public parking tons or park benches in Atlanta throughout after-hours or on weekends. After a few months, Angad and his group of over 30 volunteers developed the primary prototypes for filterless air purification units and realized methods to design take a look at rigs for constructing these methods – a course of they are saying they proceed to invent and study from even as we speak, 6 years later. 

This was additionally the time when the venture obtained the title ‘Praan’. Throughout this time, Angad and some members of the group even reached out to the Ministry of Setting, Forest and Local weather Change in India to suggest a filterless method to out of doors air purification. Following this, in December 2018, they flew to New Delhi and demonstrated the idea for his or her first prototype.

“Quickly after this, the conversations round Praan’s mission grew inside the Georgia Tech and Emory College Campuses, resulting in many extra folks making use of to affix the group of volunteers engaged on this mission. In a fraction of weeks, the group grew to 64 folks within the Spring 2019. This was the most important volunteering group [that] Praan ever had,” notes the Praan web site. 

“To develop filterless giant house air purification know-how, you want individuals with totally different specialisations—mechanical designers, chemical engineers, physicists, full-stack builders and people with an understanding of energy electronics and embedded {hardware}, amongst others. Once I began growing this know-how in my sophomore 12 months, I knew methods to construct prototypes however knew nothing about fluid dynamics,” Angad tells The Higher India.

So, how do you entice pupil volunteers to work in your venture? 

“You give them recognition on patents, which may be very worthwhile for a 3rd or fourth-year engineering pupil. And in the event you may give them actual hands-on expertise, which they’re practising by that semester, they’ve story to inform to job recruiters. Plus, given my prior expertise at MIT and the community I developed there, I knew senior individuals who labored in corporations like Apple, Tesla or SpaceX. I might assist introduce these volunteers to those folks, saying they labored on my venture. For instance, Patrick Finley, the founding father of Lander Challenger, went to work at SpaceX after working as a volunteer for Praan,” he says.

Within the following summer time, Angad returned to India with one in all his Educating Assistants (TAs) and ran additional experiments at a retailer room belonging to his father’s firm. In the meantime, Naresh Shahani (at the moment a director at Praan), helped acquire an unsecured mortgage of $15,000 to fund the analysis and improvement. Taken in Angad’s title, this sum was ultimately doubled and returned in 2021. 

Later that summer time, Angad, his TA and two interns put collectively the prototype of what would change into the MKOne Outside Air Air purifier. The plan transferring ahead was that Angad would graduate in 2020, run this firm full-time after graduating, and lift capital. Regardless of his finest efforts, securing funding was a significant problem. By January 2020, buyers hadn’t caught on to the potential of deep tech and the provides on the desk weren’t passable. 

Regardless of these challenges, he managed “to pool collectively some mushy commitments value $1.35M from an Indian VC fund and some strategic angels on very unhealthy funding phrases”. As these offers had been being finalised, the COVID-19 pandemic struck and every thing fell aside. But to graduate from school, he needed to pack every thing up and are available again to India whereas finishing on-line lessons to get his diploma.  

However there was a silver lining. Since folks had been shedding their jobs and internships, there have been many seeking to work on one thing that will advance their careers. Much like what he did earlier, Angad provided recognition on Praan patents to anybody who helped develop the know-how additional both remotely and even as a volunteer. 

In whole, Praan managed to onboard about 60 volunteers from a number of time zones who selected to dedicate about 4 months of their time to work on their know-how.  Whereas the {hardware} was constructed and developed out of Angad and his intern’s bedrooms in Mumbai, different volunteers from all over the world contributed with their concepts and engineering drawings for his or her prototypes. 

In response to the Praan web site, there have been additionally “design groups engaged on concepts for the MK One product, the indoor air purification, bioengineering, carbon seize, and software program engineering merchandise—all with none capital within the financial institution”.

Actual funding and help lastly got here within the type of Emergent Ventures, a fellowship and grant programme run by well-known economist Dr. Tyler Cowen. It gave this fledgling startup the most important grant in the course of the lockdown interval which helped them entry capital to construct prototypes and take a look at rigs as effectively. Within the subsequent few months, they developed a working prototype of the MKOne Outside Air air purifier in India.  

Nevertheless, there was little or no buyer or investor curiosity and a negligible quantity of distributors had been keen to fabricate the MKOne prototype. Angad spent about 5 months ready for distributors to fabricate the primary usable MKOne prototype. Uninterested in ready, Angad determined “to construct the primary MKOne prototype at a utensil manufacturing plant.”

Whereas there have been variations between this prototype and future merchandise by way of dimensions and ending, they lastly had an actual product that they may present buyers. Furthermore, it gave the Praan group actual confidence that they may begin to manufacture this product in India.

How does this know-how work?

Each the MKOne and the newer MK-II Air Purification methods work on comparable fundamentals. 

Chatting with The Higher India, Angad explains, “Particles are pulled in utilizing followers, charged in a really confined house, instantly separated from the air stream after which pushed down utilizing pulses into a set bucket. Merely put, it actively pulls polluted air from the highest, separates the particulate matter utilizing Praan’s patent-pending filterless know-how, collects it in a set tray and releases cleaner air again into the hyperlocal environment by the retailers.”

“The MKOne was designed for particulate matter concentrations of as much as 1000 ug/m3 whereas the MK-II manages AQI as much as 40,000 ug/m3. The MK-I used to be designed for out of doors functions–constructing compounds, frequent areas, faculty compounds, and so forth. The MK-II system was designed for industrial use circumstances—manufacturing unit flooring the place there are extremely excessive mud volumes and ranges. MKOne’s triangular design was for early prototypes since that was a comparatively simple form to fabricate. Nevertheless, the cylinder is the perfect form to make sure that the system doesn’t topple when positioned outdoors in excessive wind circumstances,” provides Angad. 

MKOne was first proven to the world in December 2020. The MK-II was designed and soft-launched in December 2023, and commercially launched in July 2023.

“MK-II has eight occasions the purification capability and 5 occasions the storage capability of MKOne,” he claims. 

Praan has additionally developed HIVE, an indoor air air purifier. Angad claims, “The HIVE software program and the EDITH AI assist that Praan supplies ensures that your air is all the time clear. Furthermore, all upkeep is managed by us.”


Lastly, relating to buyers, suffice to say that Praan has to date raised a complete of $1.9 million from VCs and Angel buyers starting from the New York-based Social Affect Capital, which, amongst others, has PayPal co-founder Peter Thiel as a backer. In addition to, they’re supported by Microsoft, Autodesk and the Marico Innovation Basis.  

Trying forward, Angad has laid out his blueprint for the longer term. 

“Praan began with the imaginative and prescient of constructing the longer term extra thrilling by guaranteeing that clear air is accessible to all. We are going to scale to make industrial, residence, business, and out of doors merchandise in air purification and mapping—each in {hardware} and AI-run software program. We may even scale direct air elimination of carbon dioxide outdoor and indoors for carbon credit score technology and everlasting storage of CO2. Our bio-engineering group has and can proceed to rebuild ecosystems whereas guaranteeing greenhouse fuel elimination all over the world,” he says.
