The future breathesCleaner air

We integrate carbon capture into building ventilation systems
turning CO2 from a problem into a resource.

What we do

UseNexus develops direct air capture technology that lives inside buildings, capturing both the CO2 people exhale and the CO2 already in the air, then turning it into a resource.

Turn your building into a climate asset

What UseNexus does for you

Reach your climate goals and exceed them
Carbon capture inside your own building delivers measurable results for your sustainability work, not just purchased credits.
CO2 becomes a resource
The captured carbon is reused in concrete, chemicals, food production and greenhouses and gains commercial value.
Integrates with your ventilation
The technology is built into existing ventilation systems and works in buildings with varying occupancy levels.
Better indoor air
Capturing CO2 from the air stream also means fresher, healthier indoor air for the people in the building.

About us

Founded by researchers. Driven by a mission.

UseNexus was founded by scientists and experts who have spent their careers in energy systems. Our goal is simple: to turn carbon from an environmental burden into a resource, and to help the built environment exceed its climate targets, not just meet them.
