Some of our customers






Too much dirt is tracked in, leaving too little time for cleaning.
When dust, sand, and moisture are tracked into the building, time is spent dealing with urgent issues instead of carrying out scheduled cleaning. Indoor air quality deteriorates, floors wear out faster, and occupants notice the difference. You shouldn't have to choose between cost-effectiveness, safety, and well-being.

Why customers choose N3 Zones

Health
When dirt is stopped at the entrance, less dust is carried further into the building. This helps create a better indoor environment in the areas where people spend time.

Economy
Less dirt and moisture in the building makes cleaning more efficient and reduces unnecessary work across large areas.

Environment
A fixed entrance solution with regular maintenance can replace routines involving loose mats, transport and chemical cleaning.

Safety
Dry, controlled entrance areas help ensure safe passage as weather and foot traffic conditions change.

Aesthetics
A clean entrance sets the standard. When the entrance area stays cleaner, the rest of the building also feels better maintained.

Responsible operations
Documented operations, training and follow-up make it easier to take a structured approach to indoor environment and quality over time.
N3 Zones in practice

Før og etter hos Felleskjøpet: Renere inngang, roligere butikk.
Når trafikken er høy og smusset grovt, starter utfordringen alltid i døren. Hos Felleskjøpet har N3 Renholdssoner blitt brukt i flere lokasjoner for å stoppe smuss og fukt før det dras videre inn, og gi en enklere renholdshverdag.

Hva er N3 Løsningen?
N3 Løsningen er fremtidens renhold som tjeneste. En helhet som kombinerer Renholdssoner, data og automasjon, slik at renhold blir smartere styrt, enklere å dokumentere og bedre for menneskene i bygget.

Jevn kvalitet hele dagen uten å øke bemanningen
Ujevn kvalitet oppstår ofte når trafikk, vær og belastning varierer. Med riktig forebygging, jevn gjennomføring og bedre styring kan bygget oppleves renere gjennom hele dagen.

Frequently asked questions about N3 Zones
“How long can N3 Zones remain in place before they need to be replaced?
As a general rule, N3 Zones should be replaced after no more than 60 months. N3 and NAAF have established this interval to provide a good balance between functionality, hygiene and predictability.
“Is a fully carpeted solution in preschools and schools hygienic, and what about allergies?
N3 Zones is not an ordinary mat, but an entrance system with unique properties designed to capture as much dirt and water as possible before they are tracked into the building. The solution was developed in collaboration with NAAF to help create a cleaner indoor environment and reduce the amount of dirt brought into areas used by children and staff.
“Can N3 Zones be used on heated floors?
Yes. N3 Zones work well with underfloor heating, which can also help the zones dry faster. The solution is designed to perform well in buildings with heated floors.
