Ethera, air quality monitoring sensors

Published on 15 December 2022
​Solutions for controlling both indoor air quality and building energy use.

Ethera’s compact, accurate, and easy-to-maintain sensors continuously monitor indoor air pollutant concentrations so that building operators can take action.

Building occupants are chronically subjected to air pollutants like formaldehyde, fine particles, nitrogen dioxide, ozone, carbon monoxide, and volatile organic compounds, to name a few. Ethera has developed sensors and measuring stations to detect them, quantify them, and report any readings that exceed regulatory thresholds.

These miniaturized, energy-efficient devices achieve the same level of sensitivity (one microgram/m3) as laboratory measurements—and they do it in real time, on-site, and at a much lower cost.

Ethera combines these solutions with services for collecting, managing, displaying, sharing, and post-processing data. In particular, these services help optimize building ventilation strategies to guarantee air quality without letting more heat out of the building than necessary.

The startup, a SEB company, holds exclusive licenses to two CEA patents.

Key figure: 7 parts per billion

Ethera sensors detect formaldehyde, the primary indoor air pollutant, at a record sensitivity of 7 ppb

Key Markets:

  • Commercial buildings
  • Smart buildings
  • Schools
  • Swimming pools and sports facilities


  • Porous materials functionalized to react to pollutants
  • Data collection, processing, and provision
  • Post-processing of data to control air purifiers, ventilation systems, etc.
