NatéoSanté, a company specializing in indoor air purification, has just launched its indoor air quality monitor, Air Coach. Based in Saint-Hilaire-de-Chaléons (Loire-Atlantique) and founded in 2009, the company has developed this tool, which goes beyond a simple CO2 or pollutant concentration detector. It is designed to be educational and predictive. It combines measurement capabilities with actionable recommendations to proactively improve indoor air quality before it deteriorates. In addition to this real-time monitoring of indoor air quality, Air Coach allows users to view data recorded over a week and download readings from the previous month. In recent years, the COVID-19 crisis has accelerated everything for NatéoSanté plans to double its workforce and grow to 40 employees by the end of 2023.
