HANOI: Independent online air quality index monitor AirVisual said on Oct 9 its air quality monitoring app is available for download again in Vietnam after it suspended it in the face of a barrage of criticism from social media users.
AirVisual, which measures air quality based on data it gets from monitoring stations, was accused by one critic of exaggerating pollution in the Vietnamese capital of Hanoi to boost sales of air purifiers made by its parent company.
