Expo City Dubai – Free Zone & Clean Air Enterprise
Expo City Dubai – Free Zone for Innovation and Sustainability
Expo City Dubai is one of the most advanced Free Zones in the United Arab Emirates. Originally developed from Expo 2020, the site has evolved into an international hub for innovation, sustainability, PropTech, and Smart Cities.
As a Free Zone, Expo City offers companies significant advantages:
- 100% foreign ownership
- Tax incentives and simplified customs processes
- Fast company setup and flexible visa regulations
- Direct access to global markets through Dubai as an international hub
- A strong network of partners in technology, real estate, health, and circular economy
Clean Air Enterprise – Trading License for Global Rollout
Since 2025, Clean Air Enterprise AG (CAE) has held an official trading license in the Free Zone of Expo City Dubai.
This license is a milestone for the worldwide rollout of our Smart Electrofilter technology, as it enables us to:
- Distribute our products directly in the UAE and across the GCC region
- Manage global projects from Dubai – from Asia to North America
- Collaborate with international partners from the Urban Lab and PropTech Institute
- Position CAE as a globally scalable ESG and longevity solution
From Black Horse to Unicorn – The Creative Destroyer
Clean Air Enterprise started as a “Black Horse”: a hidden challenger in a market dominated by disposable filters and inefficient air technologies. Step by step, our technology transforms us into a Unicorn – a globally recognized ESG impact company.
CAE embodies the role of the ‘creative destroyer’: breaking with outdated, polluting systems and replacing them with circular technology that aligns health, climate, and economic value:
- Black Carbon Removal: Our filters remove ultrafine particles (PM2.5) and especially black carbon with an efficiency of 99.5%.
- ESG Champion: With measurable impact – air quality, health, energy efficiency, and climate – CAE positions itself as an Article-9-compliant ESG leader.
- Circular Technology: Instead of disposable filters made of glass fiber, plastic, and waste, we use fully repairable filter modules made of aluminum and stainless steel – durable for 20 years.
- CO₂ Savings: Each filter saves up to 3.5 tons of CO₂ over its lifecycle by reducing energy consumption (cooling/heating) and avoiding waste incineration.
- Creative Destruction: CAE replaces disposable, throw-away products with a future-proof solution – and redefines the standards for healthy air.
Digital Product Passport (DPP) – Excellence in Transparency and Traceability
CAE offers an excellent Digital Product Passport (DPP) that ensures transparency across the entire lifecycle of our filters. It documents material use, energy savings, CO₂ reduction, and repairability – setting a benchmark for circular technologies.
Thus, CAE builds a bridge from health to climate, from local impact to global scale – evolving from the ‘Black Horse’ into the Unicorn of air and climate technologies.
