Breathe London Node



Price £2000 + VAT

Pre-deployment checks, free replacements and tight integration with the London Air reference network makes the Breathe London Node the perfect small sensor for local air quality monitoring.


Detailed Description

Before you purchase a Breathe London Node, we encourage you to read our guide on choosing a good location for your Node and advice on seeking permission if you want to attach it to on TfL or Council-owned street furniture.


There is no limit on number of Nodes that can be purchased by any individual or organisation, but we limit purchases to one at a time so we can collect information such as Node name and location for the website.

The purchase price is split between Clarity and Imperial, is billed annually, and includes pre-deployment checks and realtime network QA/QC.

No money for purchased Nodes goes to the Greater London Authority (GLA).
