clean air
Smog's polar opposite
Clean air is air that is free from pollutants, contaminants, and harmful substances—the kind humans and other living things need to breathe for good health.
The term appears frequently in environmental and public health contexts, where it often refers to air quality standards set by governments: The Clean Air Act regulates emissions from industrial sources.
Clean air may also describe the simple pleasure of fresh, unpolluted atmosphere: We moved to the mountains for the clean air.
