Four special air purifiers were 'planted' in Omonia Sqaure by Politis Group, in cooperation with the Municipality of Athens.
Air pollution remains the number one environmental health problem in the EU.
According to estimates of the European Environment Agency, around 400,000 premature deaths can be attributed to air pollution each year in the EU. This type of pollution is the cause of serious illnesses such as asthma, cardiovascular problems and lung cancer.
Emissions from vehicles are responsible for 70% of the Greek capital's air pollution.
Due to the lack of greenery (trees clean the air and absorb harmful airborne particles and gaseous pollutants), four air filters (equivalent to 30 trees) were installed in the Athenian neighbourhood.
Omonia square was specifically chosen because the area has high concentrations of microparticles, continuous flow of vehicles and tall buildings, which trap pollution. As a result, the quality of the air is poor.
The devices - 'Pamares' - reduce a large array of (ultra-) fine particulate matter of 30% in outdoor areas. They are also sustainable and totally noise free.
