Electrostatic filter for wood-burning stoves aims to improve air quality
In a new development project, the Danish Technological Institute and NBE Production are working together to develop an affordable, user-friendly filter solution capable of reducing particulate emissions from wood-burning stoves. With an expected reduction of up to 80% and a strong focus on ease of use and affordability, the project addresses both the environmental and public health challenges associated with local air pollution.
Better Solutions to a Well-Known Problem
Wood-burning stoves are responsible for a significant share of Denmark’s harmful particle emissions and are therefore a key area of focus in efforts to improve air quality, particularly in urban areas. Existing technologies have yet to achieve widespread adoption, mainly due to high costs and demanding maintenance requirements. This project seeks to develop a cost-effective solution that reduces pollution without requiring complicated installation or maintenance.
“By combining our technological expertise with a strong focus on user needs, we are developing a solution that not only improves air quality, but also makes it easier to incorporate environmental considerations into everyday life.”
What makes this solution stand out is its location inside the home and its simpler overall setup. The filter will be installed indoors — for example, in the living room or attic — making it easier to access for maintenance. At the same time, the maintenance process is being redesigned to be as simple as possible, allowing users to handle it themselves. This is intended to ensure consistently high performance throughout the lifetime of the filter — something that has been difficult to achieve with existing solutions.
A Smarter Solution for Both the Environment and Consumers
Stricter EU air quality requirements, together with national targets for reducing particulate emissions, create strong market potential for solutions like this. In addition to fine and ultrafine particles, the filter also captures black carbon — a major contributor to global warming. The solution is expected to cost around DKK 10,000, making the technology accessible to a wider audience.
