An air quality ecosystem for indoor spaces everywhere

Our air quality ecosystem is purpose-built for populated indoor spaces that rely on mechanical HVAC systems – spaces like office buildings, healthcare facilities, university campuses, or public transport systems.

We integrate with your existing HVAC systems to radically lower energy consumption and emissions. Even if your indoor spaces can’t be physically altered, we can still help you decarbonise and save money.

With two decades of leadership delivering certified air quality solutions, our technology is trusted by businesses, healthcare, transportation and education providers in more than 40 countries over five continents.

Where we operate


We help organisations radically reduce energy consumption and save money across their real estate without ripping and replacing existing ventilation.


We improve indoor air quality in every classroom and lecture hall while bringing down energy costs – even in older buildings.


Our technology helps leading healthcare providers transform indoor air quality and improve patient safety by reducing airborne transmitted diseases.


Transport providers rely on Rensair to clean the air and make every journey healthier and happier for passengers and staff.
