After a few days of rain and wind in Madrid, we can finally breathe fresh air, according to this app I downloaded, helping me to monitor which days I should be more cautious…but what can I do if the air of my city is polluted?

You hear more and more speaking about air quality, pollution migrants, because demand for breathable air is growing. Following this critical problem statement and demand for solutions, supply is developing as well, in many different ways:
– Monitoring apps: collecting and interpreting data, creating rankings of different cities and districts, displaying results, effects and advise to the users.
– Air sensors: there are air quality sensors available to be installed together with your ambient thermometer and meteo station, on your balcony. They can be coupled with an app and/or provide you local information.
– Home purifiers: speaking about solutions, the market of air purifiers is growing, set to hit $29bn by 2021.  There are different technologies, ranging between 40$ and 150$ and different HEPA filters.
– Outdoor purifiers: without going into exotic inventions, there have been experimented coating solutions which react with pollutants (e.g. SO2, NOX, O3), retain particles and release O2, oxygen. Those liquids are available for B2B and institutions to spray buildings, roads, commercials etc.

While selling physical products has a straight forward business model, it is not that clear how apps developers can make any money from distributing free insights online and, in fact, most of them are associations (e.g. State of the Air) or they use the app as a channel to sell related products (e.g. AirVisual).

What is very clear is the renewed attention for this topic and the huge potential for new clean tech businesses.
