Compact In-Car Air Purifier with PCO Technology
Advanced PCO air purification using UV LED and titanium dioxide – made compact for your personal space.
Case
Client
A mobility-focused lifestyle brand looking for an ultra-compact, low-noise air purification solution that can be used safely in confined car interiors — without the need for filters or ozone-emitting devices.
Problem
Traditional car purifiers use HEPA filters or ionizers, which either generate ozone or require filter changes. Drivers needed a safer, maintenance-free alternative that could neutralize odors, smoke, and airborne bacteria in real-time during driving or idling.
Strategy & approach
We designed Air Shot Road with TiO₂-based photocatalytic oxidation (PCO) in a vertical tower design that fits seamlessly into any cup holder. By combining UV-A LED with a honeycomb filter, we ensured complete sterilization and odor removal without consumables or ozone generation.
The device draws in cabin air through the side mesh, processes it via the PCO chamber, and gently releases clean air upward — without noise, without heat.
Tools & methods used
- 365nm UVA dual-LED system
- Ceramic TiO₂-coated filter with hexagonal airflow design
- Zero ozone generation (KTR certified)
- USB power (5V, 1A) with micro-USB or USB-C
- Designed for car cup holders (70mm diameter / 120mm height)
Achieved results
Why PCO for Vehicles?
Unlike ionizers or ozone generators, PCO uses light-activated oxidation to destroy harmful compounds at the molecular level – silently and continuously. It is safe for use in small, enclosed spaces like cars.
