Special bumpers on ships filter water while loudspeakers purify the air.
Now a Romanian startup is combining air purification with a new marketing opportunity for firms.
Its large-scale air filter stations for shopping centres, petrol stations or airports contain digital displays which companies can book through an online platform to advertise their brands.
Cutting property owners’ costs for clean air in parallel. The stations filter poisonous gases, dust, bacteria or pollen as well as soot and tyre abrasion particles. Air quality is monitored in real time.
The next planned step is a pilot project before units are rolled out to major cities in Europe.
Another solution makes for a personal supply of fresh air.
