With more and more travelers looking to take a breather from pollution, it’s no surprise that destinations are starting to boast about having the world’s cleanest air. But even in the wilds of Alaska it’s possible to suck in trace elements of toxic fumes from Siberian coal mines. So where, exactly, can travelers go to be sure of finding pure O2?
Air cleanliness is usually measured by monitoring stations set up by local governments with the purpose of assessing long-term changes in carbon dioxide or ozone. These stations track air purity by measuring more than 250 pollutants, which can vary drastically in their harmfulness. Air that looks clean can still harbor invisible, odorless toxins, while a hazy horizon can sometimes be caused by harmless water vapor.
Travel and Leisure’s list of places with the cleanest air are: Tasmania, Big Island, HI, Iceland, Cape Peninsula, South Africa, Tahiti, Samoa, Antarctica, Easter Island, Patagonia’s Lakes, and South Island, New Zealand,
