Public Health Issue

Indoor Air Quality: a major public health issue


of europeans are living in a polluted air


of buildings have at least one source of indoor pollution

million french people suffer from respiratory allergy - a figure that has doubled in 15 years

deaths are linked with air pollution every year in europe


Indoor Air Quality Measurement


This device is made for indoor air quality (IAQ) diagnosis and analysis campaigns. It is an ideal solution for building inspections to meet national IAQ-related guidelines. This station can be connected to IoT networks such as Sigfox, LoRA et LTE-M. An air quality report will be generated automatically at the end of the diagnosis campaign to compare with figures of reference.

Our stations can be found connected in most countries via Sigfox, LoRa, LTE-M, NB IoT…). It is easy to set up wirelessly in either public or private networks. Also available on local communication protocol Modbus.

Air Purification


Ethera’s PURETECH Granules allow to specifically trap formaldehyde without any release. Several types of granules have been designed to absorb formaldehyde in a long-lasting way, unlike active carbon, without releasing the gas in flowing air. A number of home electrical appliance manufacturers have been relying on our technology. Available in powder or granulated form.
