About N3
About N3
N3 was founded by Dag Hognerud and Henrik Foss with a clear ambition: to find a more effective and sustainable way to keep dirt and moisture out of buildings.
Dirt and moisture affect more than just floors. They influence cleaning requirements, indoor air quality and the everyday environment for everyone who uses a building. Over the years, we have developed our offering from effective entrance solutions into the N3 Solution: an integrated approach that combines N3 Zones, smart technology and automated cleaning. It helps organisations prevent dirt from entering, manage cleaning more efficiently and gain better insight into the quality of their operations.

A complete cleaning solution for everyday operation
We start with the building, not the product. Every building has its own needs, shaped by foot traffic, entrances and daily activities. Understanding these factors helps us identify where dirt and moisture enter and what affects cleaning requirements and indoor air quality.
By stopping more dirt and moisture at the entrance, N3 helps create more consistent cleaning results and more predictable day-to-day operations.
Our integrated solution brings together N3 Zones, smart technology and automated cleaning. Together, these elements help organisations prevent dirt from spreading, understand what is happening in their buildings and follow up on cleaning performance over time.
We focus on solutions that work in practice. With close follow-up and clear responsibilities, we help make everyday cleaning easier to manage, measure and improve.

Proven solutions in thousands of buildings
With decades of experience and a long-standing collaboration with the Norwegian Asthma and Allergy Association, N3 develops solutions that support better indoor air quality and more predictable cleaning operations.

Sustainability
Making sustainability part of everyday operations
At N3, sustainability is about making improvements that work in practice and can be measured. We work systematically to reduce our environmental impact and develop solutions that support more resource-efficient cleaning operations.
By preventing dirt and moisture from entering buildings, we can help reduce cleaning requirements, unnecessary resource use and wear on interior surfaces. We focus on practical improvements that create lasting value for both buildings and the people who use them.

NAAF
Working together for better indoor air quality
The Norwegian Asthma and Allergy Association (NAAF) is an important partner in N3's work to improve indoor environments.
Our collaboration focuses on prevention, cleaning quality and solutions that help reduce the impact of dirt and dust in buildings. Together, we work towards healthier indoor environments in schools, workplaces and other buildings where people spend their everyday lives.

Partnerships
Building better solutions together
Strong partnerships are an important part of how we develop N3. We work with organisations that share our commitment to improving cleaning quality, documentation and sustainability.
By combining knowledge and expertise, we develop practical solutions that respond to real needs in buildings and everyday operations. Our partnerships help us create more value and make cleaning easier to manage for the organisations we work with.
