Infuser Denmark

A creative engineering company with a passion for atmospheric chemistry. Atmospheric gases and light are responsible for protecting all living organisms on the Earth’s surface. It is the right composition of gas and light that protects and maintains a clean environment in our oceans and in the air we breathe. In close collaboration with the Center for Atmospheric Research at the Department of Chemistry, University of Copenhagen, INFUSER develops and implements technologies for the production, management and infusion of natural atmospheric gases with the objective of decontaminating air and water.

INFUSER is a company driven by a passion for atmospheric chemistry

INFUSER’s headquarters is located at the heart of Copenhagen Science City, a district in Copenhagen centered around the University of Copenhagen, the Metropolitan University College and Copenhagen University Hospital ( Rigshospitalet ). Copenhagen Science City comprises one of the largest areas of education, research and applied science within natural sciences in Europe.

Passionate about atmospheric chemistry

Through a strong affiliation with the University of Copenhagen, INFUSER has assembled a leading team of atmospheric scientists and engineers devoted to atmospheric chemistry, and the development of advanced pollution control solutions.

INFUSER’s innovative solutions are based on applied research and science. After thorough testing in laboratories and industrial settings, the scientific work is transformed into sustainable commercial solutions.

Products and solutions are designed with a keen eye on efficiency, durability and functionality. INFUSER’s team of atmospheric chemistry scientists is supported by industrial designers, mechanical and electrical engineers who guide the transition from research findings to industrial solutions. The solutions address emissions that come from the volatile organic compounds (VOCs), sulphur oxides (SOx) and nitrogen oxides (NOx). The objective is to help industries reach emission standards levels.

INFUSER launched one of the most sophisticated and well equipped air pollution abatement laboratories in Europe early 2016. It serves as a major research and development tool, as well as for testing of air samples from all over the world. The facility is located in Copenhagen Science City, providing INFUSER with the unique opportunity for tapping into the network of talented young scientists and engineers from across the world.


INFUSER’s purification technologies use advanced atmospheric oxidation to remove pollution. This is achieved by utilising the natural self-cleaning mechanisms of the Earth’s atmosphere in closed reactor systems.

The INFUSER system is designed to purify air using significantly less energy than conventional methods. It does so by eliminating the need to force air through ineffective static filters, which typically leads to large pressure differences and energy losses.

The composition of gases in the unperturbed atmosphere along with light protects and maintains a clean environment in our oceans and in the air we breathe by removing pollutants through photochemical cycles.

A large part of anthropogenic pollution consists of hydrocarbons. When hydrocarbons are emitted to the ambient atmosphere, they react with naturally occurring compounds to form particles in a process triggered by sunlight. These particles are removed from the atmosphere via dry or wet deposition.

INFUSER’s science is focused on combining and accelerating these natural processes in a controlled environment. If a pollutant is captured and removed at the source before it can escape into the surrounding atmosphere, its negative effect to the environment, and those dependent on the environment can be avoided. The Photochemical Air Purification technology, invented by the University of Copenhagen innovation award winner Professor Matthew S. Johnson, prevents polluting gasses and particles from entering the atmosphere by accelerating these natural processes by a factor of 105 in a controlled reactor environment.

Climate change poses a significant challenge for the world at large. As greenhouse gas emissions increase, sea levels are rising, average global temperatures are increasing, and severe weather patterns are accelerating. Climate change may also exacerbate water scarcity and lead to sharp increases in food costs.

The pressures caused by climate change will influence resource competition while placing additional burdens on economies, societies, and governance institutions around the world.


Cleaner environments through sustainable technologies, which improve the well-being of living organisms.


Utilise existing, and create new knowledge in atmospheric and ozone sciences for society’s greater good.

INFUSER’s DNA, the scientific knowledge and capabilities, allow the company to provide efficient and effective solutions for:

A) Advanced Pollution Control: modular design systems that treat industrial emissions – volatile organic compounds (VOCs), sulphur oxides (SOx), and nitrogen oxides (NOx).

Atmospheric chemistry, and the principle of advanced atmospheric oxidation is what removes the air pollution from industrial emissions. It works on the principle of combining the natural self-cleaning properties of the Earth’s atmosphere in a closed reactor system.
Climate change poses a significant challenge for the world at large. As greenhouse gas emissions increase, sea levels are rising, average global temperatures are increasing, and severe weather patterns are accelerating. These changes, coupled with other global dynamics, including growing urbanization, more affluent populations, and substantial economic growth, will devastate homes, land, and infrastructure. INFUSER takes a stand in tackling environmental issues that affect communities in proximity to air polluting industries. The primary concern is the health and well-being of living organisms.

B) Purification and whole – room decontamination: grease removal and smell reduction in kitchen exhausts / ventilation ducts, and elimination of viruses, bacteria and spores.

INFUSER’s purification technologies utilises the properties of the ozone.
