According to the agency, the mechanical air cleaning hoarding filters and purifies the surrounding air and releases it back to the environment.
The installation incorporates a mechanical filter and activated carbon which draws in air from the back of the billboard and filters dust particles and harmful gases.
Santosh Menon, managing director of BBDO Lanka, said in a statement that the agency “wanted to make a contribution to the environment”.
“The environment we live in, particularly the air we breathe, is continuously under attack from the various pollutants released into the atmosphere,” he said, adding that he expected the billboards to have an impact on the “entire Sri Lankan community” over time.
The move has been praised by the deputy minister for the environment, Abdul Cader. “The fact that [BBDO] not only initiated this idea but are also willing to give [it] out for free to any company interested in implementing it speaks volumes for the level of commitment the company has toward improving the standards of living for the community,” Cader said at the unveiling.
