Improving air quality in cars
Healthy Air Technology systems combine filtration and catalyst technology.
HEPA-13 filtration is designed to capture airborne particles, while D-Orbital Nano Oxide (DNO) catalyst technology is designed to convert selected gaseous pollutants, odours and bioaerosols into harmless substances without generating secondary pollution. Our patented DNO catalyst technology represents a major breakthrough in air purification technology.
Features, intended settings and available evidence vary by product.
Technology
Introducing Advanced Air Filter Technology:
Healthy Air Technology develops air purification solutions that combine HEPA-13 filtration and patented D-Orbital Nano Oxide (DNO) catalyst technology. Selected models also include sensing and airflow features suited to their intended setting.
HEPA-13 filtration is designed to capture airborne particles. DNO technology is designed to address selected gaseous pollutants, odours and bioaerosols. Product configurations, intended environments and test results vary by model. Read the relevant product page and the Evidence & Test Results summary for product-specific information.
Understanding Air Pollution:
Air pollution is a complex mixture of fine particles and gases, including PM2.5, PM10, nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide and volatile organic compounds. These pollutants come from a range of sources, including transport, cooking, cleaning products and building materials.
The health burden is substantial. The World Health Organization (WHO) estimates that the combined effects of ambient and household air pollution are associated with 6.7 million premature deaths each year. The State of Global Air Report 2024, produced in partnership with UNICEF, attributed 8.1 million deaths globally in 2021 to air pollution and ranked it as the second leading global risk factor for death.
In the UK, long-term exposure to air pollution has an effect equivalent to an estimated 29,000 to 43,000 deaths each year. The main health burden is linked to cardiovascular and respiratory disease, including heart disease, stroke, chronic obstructive pulmonary disease, lower respiratory infections and lung cancer. Children, older people and people with existing heart or lung conditions are among the groups most vulnerable to poor air quality. Read the GOV.UK summary.
People are not protected from air pollution indoors or inside vehicles. Outdoor pollutants can enter buildings and vehicles, while indoor sources can cause air-pollution peaks. Air purification can support indoor air-quality measures alongside source control and ventilation.

What is secondary release and why is it a problem?
Secondary release is common in filtration systems that only use HEPA filters. It is when bacteria, viruses and chemicals trapped in the filter are released at a later point, leading to re-infection and negative health outcomes. Healthy Air Purifiers remove the possibility of this happening by using our DNO technology to completely break down and kill these elements.
Can I find DNO technology in any other machines?
No, D-Orbital Nano Oxide (DNO) catalyst technology is patented by Healthy Air Technology Ltd.
