Building air-quality function into the spaces around us.

Clean air, built into the building.
Not added afterwards.
After building and exiting a global clean-air technology company, I came to a simple conclusion:
The next generation of indoor air technology will be built differently.
Use the architecture.
Use the airflow.
Use what is already there.
PASSAIR develops patent-protected technologies that integrate clean-air and airflow function into the built environment.
What if clean air became part of the infrastructure itself?
The surface only works if the air reaches it.
The right surface, in the right particle pathway, can create useful environmental function.

More modelled particle deposition than standard skirting.
Under matched CFD conditions, our latest Skairting configuration recorded 42,701 deposited PM2.5 particles compared with 7,440 for standard skirting.

PM1
Smaller particles. Stronger modelled interaction.
Our CFD modelling shows the PASSAIR HVAC architecture preferentially retained the smaller particulate classes under the tested conditions.

Not every airflow solution needs another fan.
PASSAIR is developing architecture that captures, conditions and makes naturally occurring indoor airflow more useful.
Application areas under development
- Air quality
- Mixing
- Stagnant zones
- Thermal movement
- Comfort
One platform.
Four ways into the built environment.
Perimeter
Use the boundaries already around us.
Skairting™, Cooving™ and Perimetair™ turn architectural perimeter into environmental infrastructure.
Explore Perimeter
Integration
Use what is already there.
Screens, acoustic panels, walls and other building elements can become part of the clean-air infrastructure.
Explore Integration
Airflow
Useful airflow. Without another fan.
Patent-pending Passive Airflow Conditioning designed to make naturally occurring indoor airflow more useful.
Explore Airflow
HVAC
Improve the systems buildings already use.
Physical interventions designed to influence particle behaviour within existing HVAC infrastructure.
Explore HVAC
Upgrade the infrastructure already there.

- Building-integrated environmental features
What if the right intervention hasn’t been designed yet?
Air Intelligence can identify where an indoor environment needs help. AI Design can eventually create a physical response around the needs of that specific space.
Air Intelligence finds the opportunity.AI Design creates the response.PASSAIR makes it physical.
