Air is the
commons
we forgot.
Seven million people die each year from air pollution. The solutions have remained industrial — mechanical filters, energy-hungry systems that consume resources while claiming to protect them.
Aeropure takes a different path. We deploy living photobioreactor infrastructure in the spaces between people: bus stops, transit halls, plazas, industrial perimeters. Biology does the rest.
.Every installation is a node in a living urban nervous system.
+Story
"What if the most powerful air purifier already existed in nature?"
The Question
We asked a simple question.
Air is the invisible foundation of life. Every breath we take connects us to forests, oceans, and the delicate balance of our planet. Yet in the modern world, the air we breathe is increasingly polluted.
The Discovery
Long before machines, before chemicals, before humanity itself — microalgae were quietly engineering the atmosphere. These microscopic organisms produce more than half the oxygen on Earth.
For 3.5 billion years, they have been the planet's most efficient air purification system. We didn't invent the solution. We learned how to work with it.
That question became Aeropure. Not a company built on filters and machines, but on a deep respect for what the Earth already knows how to do.
The Mission
Aeropure was created to bring natural technology into the modern world. We combine biotechnology, engineering, and environmental science to build living air purification systems.
From cities in India to innovation hubs in Europe, from smart buildings in the Middle East to sustainable campuses in the United States — we are building climate solutions for where the world is going.
3.5 billion years of research and development — available now.
The Vision
We believe the future of clean air will not come from machines alone. It will come from working with nature — with the organisms that have sustained life on this planet since before humans existed.
Aeropure is not just creating air purifiers. We are building the infrastructure for a new kind of city — one where clean air is not a luxury, but a living system.
"The future of clean air is alive."
Built for a changing planet.
Nature's oldest technology.

+ FREQUENTLY ASKED QUESTIONS
What is Aeropure Technologies?
Aeropure Technologies is a climate‑tech company that builds living microalgae photobioreactors to capture carbon dioxide and purify polluted air in cities. Our systems are designed as urban infrastructure that fits into existing spaces like bus stops, transit hubs, and building edges.
What is AeroZer0?
AeroZero is our flagship outdoor photobioreactor unit that uses microalgae to absorb CO₂ and air pollutants while releasing oxygen, creating a visible, living clean‑air system for urban environments. It is compact, self‑contained, and engineered for continuous 24/7 operation with minimal maintenance.
What kind of pilot projects do you offer?
We typically propose pilots of 3–10 units at representative sites to demonstrate technical performance, citizen response, and operational logistics before larger rollouts. Each pilot includes site assessment, installation, training, and a structured monitoring and reporting plan.
How does AeroZero clean the air?
Microalgae inside AeroZero perform photosynthesis, absorbing CO₂ and certain pollutants from the surrounding air and converting them into biomass and oxygen. Integrated circulation, lighting, and control systems keep the culture in optimal conditions so the unit can continuously capture carbon and improve local air quality.
How is this different from a normal air purifier?
Conventional purifiers rely on mechanical filters and fans, which trap particles but do not actively remove CO₂ from the air. AeroZero is a living system that captures CO₂ biologically, produces oxygen, and generates useful biomass instead of spent filters that must be discarded.
What is a photobioreactor?
A photobioreactor is a controlled vessel where microalgae grow using light, CO₂, water, and nutrients, optimized for high photosynthetic efficiency. It allows precise control of parameters like light intensity, temperature, and pH to maintain stable, productive algal cultures for air purification and carbon capture.
How efficient are microalgae compared to trees?
Studies and pilot projects show that microalgae can be 10–50 times more efficient than trees at capturing CO₂ per unit area under controlled conditions. Urban photobioreactor installations have demonstrated that a single unit can match or exceed the CO₂ uptake of multiple mature trees in dense city locations where planting enough trees is not feasible.
How much CO₂ can AeroZero capture?
Microalgae commonly used in photobioreactors can fix around 1.8 kg of CO₂ per kilogram of algal biomass produced, and controlled systems can reach high daily uptake rates per volume. AeroZero is engineered to leverage these efficiencies within a compact footprint, allowing meaningful CO₂ capture from a small area compared to traditional greening solutions.
Does AeroZero filter particulate matter (PM2.5 / PM10)
Microalgae primarily target gaseous pollutants like CO₂, but air contact surfaces and liquid–gas interfaces in photobioreactors can contribute to capturing some particulate and soluble pollutants. AeroZero is intended to complement, not fully replace, existing mechanical filtration and policy measures for particulate pollution control.
Is there any ozone or chemical by‑product?
Unlike some electronic air purifiers, algae‑based systems do not generate ozone as a by‑product because purification is driven by photosynthesis, not high‑voltage ionization. The main outputs are oxygen and algal biomass, which can be safely harvested and valorized.
Where can AeroZero be installed?
AeroZero is designed for outdoor and semi‑outdoor public spaces such as bus stops, transit hubs, building forecourts, campuses, and corporate parks. It can also be deployed at high‑footfall locations like airports, plazas, and institutional entrances to serve both functional and educational roles.
How much space and power does it need?
The unit is engineered to have a compact footprint of approximately one square meter, enabling integration into dense urban sites. Power consumption is optimized through efficient pumps and lighting, making AeroZero suitable for continuous operation and integration alongside renewable energy where available.
Does it work at night or on cloudy days?
AeroZero combines natural daylight with artificial lighting so that the microalgae can continue photosynthesis and CO₂ uptake beyond daylight hours. This hybrid approach allows more stable, predictable performance across seasons and weather conditions compared with fully passive systems.
How visible is the impact to people using the space?
Users see a transparent or translucent “living column” with gently circulating green culture, sometimes with real‑time data displays for CO₂ levels or air quality. This makes the system both a functional device and a public communication tool about climate action and urban air quality.
How often does AeroZero need maintenance?
Typical maintenance involves periodic biomass harvesting, top‑up of water and nutrients, and basic inspection of pumps and lighting, often on the order of weeks rather than days. We design service plans so that operators or city partners can manage units with simple routines, supported by remote monitoring where required.
What happens to the algae biomass?
Harvested microalgal biomass can be used as an input for fertilizers, compost, biobased materials, or as a feedstock for biofuels and other biorefinery products, depending on local regulations and partners. This turns carbon captured from the air into a tangible resource instead of waste.
Is the system safe for people and the environment?
AeroZero uses non‑toxic microalgae species similar to those found in natural freshwater environments and does not aerosolize the culture into the air. The system is sealed, monitored, and designed to meet applicable electrical and safety standards for public‑facing infrastructure.
How resilient is it to heat, rain, or dust?
Photobioreactor enclosures are built to withstand outdoor conditions, including UV exposure, rainfall, and typical urban dust loads, with materials and sealing designed for long‑term use. Algal strains are selected and conditioned for thermal tolerance appropriate to local climate, and operational controls help maintain viable growth conditions.
How do you measure AeroZero’s impact?
We quantify performance through CO₂ uptake estimates based on culture productivity, real‑time monitoring of operating conditions, and periodic calibration with lab measurements. In pilots, we also track local air quality indicators and correlate them with unit operation to build location‑specific impact baselines.
Can AeroZero solve a city’s pollution problem by itself?
AeroZero is designed as part of a broader toolkit: emissions reduction, transport policy, urban planning, and green cover expansion all remain essential. Our role is to add high‑efficiency, small‑footprint carbon and air quality infrastructure where other options are constrained by space or feasibility.
Do you work with governments and city agencies?
Yes, algae‑based urban photobioreactors are already being piloted with municipalities and public institutions in several countries as demonstrators of sustainable air infrastructure. Aeropure is actively engaging with city departments in India to pilot AeroZero units at selected high‑impact locations through small, time‑bound deployments.
Why do you sometimes compare AeroZero to ‘X number of trees’ if you are not replacing them?
Tree‑equivalent figures can help people intuitively understand CO₂ capture, but they are always approximations and only about carbon, not about shade, soil, or biodiversity. Wherever we use such comparisons, we also clearly state that natural trees and ecosystems offer a much broader set of benefits and must always come first in climate and urban planning
Who is AeroZero for?
AeroZero is suited for city authorities, transport operators, campuses, real‑estate developers, and corporates who want visible, measurable climate and air‑quality interventions in their spaces. It also appeals to organisations seeking educational or experiential climate infrastructure that engages the public.
How much does it cost?
Pricing depends on configuration, number of units, and project scope; detailed proposals are shared after a brief site and requirement assessment.
How can we get started with AeroZero?
You can contact our team with basic details of your site, objectives, and timelines, and we will propose a tailored pilot or deployment plan. From there, we conduct a technical walkthrough, finalise configuration, and support you through installation, training, and operation.
Is AeroZero meant to replace trees?
No. AeroZero is not a replacement for trees or forests; it is a complementary tool for dense urban spaces where planting enough trees is physically impossible. Experts consistently emphasise that no machine can replace natural ecosystems and their biodiversity and cooling benefits.
Why use algae systems instead of just planting more trees?
Wherever there is space, we strongly support planting and protecting trees first, because they deliver shade, biodiversity and long‑term ecological value that technology cannot. AeroZero is designed for “hard” locations like traffic islands, built‑up corridors, or transport hubs where you cannot put soil and roots but still need localised CO₂ and pollution mitigation.
How do you justify the cost compared to trees?
Planting and maintaining a mature urban tree often requires years, dedicated soil volume, and long‑term care, whereas AeroZero can be installed quickly in built‑up areas and start capturing CO₂ immediately. We look at total lifecycle value: CO₂ captured per year in constrained spaces, educational and behavioural impact, plus the ability to recover biomass as a resource, not just the upfront hardware cost.
Does AeroZero take budget away from tree‑planting or health programmes?
We design projects so algae infrastructure complements, not competes with, existing greening, health, or transport budgets, often by targeting small pilot lines or innovation funds. In proposals, we clearly position AeroZero as a focused intervention for specific hotspots, while encouraging parallel investment in trees, public transport, and emissions reduction.
