Healthy Air solutions

Breathe easy.
Healthy Air Technology Ltd (HATL) is an indoor air quality company founded in Oxford in 2018 and based at Oxford University Begbroke Science Park. It was co-founded by Dr Chunli Cao, an engineer specialising in air pollution and building science, and Dr Tiancun Xiao, a catalysis chemist at the University of Oxford. Our air purifiers pair HEPA-13 filtration, which captures fine particles such as PM2.5, with our D-Orbital Nano Oxide (DNO) catalyst, which is protected by four Chinese patents. The DNO catalyst is designed to break down selected gases, odours and biological contaminants at its surface, rather than only trapping them in a filter. The range includes vehicle, desktop, wall-mounted, freestanding and ceiling units, from the HA30 for cars to the C1300 for large rooms, for homes, workplaces, healthcare, education and retrofit buildings. Products are tested by independent laboratories, with results published on our Evidence & Test Results page, and we supply customers in six countries from our Midlands warehouse in Nottingham.
Designed for real indoor environments
Indoor air quality changes throughout the day as people enter rooms, activities change, and pollutants are introduced from indoor and outdoor sources. Healthy Air systems are designed to respond to changing conditions, helping reduce airborne particles, selected gases, odours, and biological contaminants under appropriate operating conditions.

What is DNO catalyst technology?

Healthy Air systems combine established HEPA-13 filtration with HATL’s patented D-Orbital Nano Oxide (DNO) catalyst technology. HEPA-13 filtration captures fine airborne particles, while DNO catalyst media are designed to address selected gaseous pollutants, odours, and biological contaminants at the catalyst surface.

About Us

Healthy Air Technology began in an Oxford science park, where engineering in air pollution and building science met catalysis research. That combination still shapes how we work: every product is designed around real indoor spaces and supported by independent testing.
