How Passive Vehicle Technology Can Clean Urban Air at Scale

As air pollution continues to challenge public health and urban liveability, Cleairo™ offers a powerful, passive solution: turning everyday vehicles into mobile air purifiers. Here’s how it works—and why it matters.

1. The Power of Photocatalysis

Cleairo™ modules leverage passive photocatalytic filters, typically using titanium dioxide (TiO₂). When light activates these filters, they break down pollutants into harmless byproducts like oxygen and water—no electricity or maintenance required.

  • Recent studies highlight how photocatalytic materials can effectively degrade both organic and inorganic air pollutants under ambient conditions (WIRED).

2. Vehicles as Mobile Purifiers

Traditional air cleaning solutions rely on stationary setups. Cleairo™ flips that paradigm by mounting discreet modules into vehicle wheel spaces, allowing them to purify air as vehicles move through streets.

  • Early patents describe structures that use vehicles’ own airflow systems for air intake and passive filtration—underscoring the feasibility of mobile air purification (Google Patents).

3. Real-World Validation

Though Cleairo™ is unique, existing research supports its innovation:

  • A study at a train station found portable purifiers inside public transport greatly reduced PM2.5 concentrations, suggesting potential for mobile applications (Patsnap Eureka, ScienceDirect).
  • Urban research from the University of Antwerp et al. explores semi-passive photocatalytic surfaces on street walls as effective pollution reducers, reinforcing the technology’s real-world relevance (COMSOL).

4. Modular Simplicity and Scalability

Cleairo™ is designed for quick installation—typically under 5 minutes per vehicle, no tools required, and with no vehicle redesign. This makes scaling across city or corporate fleets fast and cost-effective.

  • While specific references for installation time are brand-specific, this aligns with Cleairo’s core design philosophy: fast, passive, and scalable deployment.

5. Impact via Scale

Every Cleairo™ module is an ongoing purifier that continues to clean surrounding air as vehicles move—even when parked. Multiply that by hundreds or thousands of vehicles, and the mobile purification network quickly achieves city-scale impact.

  • Though academic studies of this exact scale are limited, the underlying photocatalytic and passive filtration principles are well-established and increasingly deployed in urban infrastructure (acsa-arch.org, mdpi.com).

6. Why Passive Tech Matters

  • Zero power consumption—no batteries, wires, or energy supply needed.
  • Minimal upkeep—no filters to replace or fans to maintain.
  • Constant operation—rides or idle, Cleairo™ keeps cleaning.
  • Easily demonstrable results—air quality gains can be tracked per vehicle and aggregated for city-level reporting.

In Summary

Cleairo™ bridges laboratory-grade photocatalysis and real-world scalability. By embedding passive air filters in vehicle wheels, it turns daily transit into a powerful clean-air campaign—offering a cleaner, healthier urban future without major infrastructure investment.

By transforming everyday vehicles into mobile air purifiers, passive technology like Cleairo™ can deliver measurable city-wide health benefits—without consuming a single watt of electricity.
