Here Are 5 Countries With The Cleanest Air On Earth:

1. Iceland

Average AQI: 21
Iceland is known for its dramatic landscapes, but its air quality is just as impressive. With minimal industrial pollution and an abundance of renewable energy (thanks to all those geothermal hot springs), Iceland's air is as fresh as it gets. Even in the capital, Reykjavik, you won't find that heavy city smog that plagues other urban areas. Instead, you're more likely to catch the scent of the ocean breeze or the occasional whiff of sulphur from a natural hot spring. If you really want to fill your lungs with the cleanest air, head to the highlands or the remote Westfjords — you'll feel like you're breathing in pure oxygen.

So, whether you're road-tripping along the Great Ocean Road, diving in the Great Barrier Reef, or just hanging out in a Melbourne cafe, you'll be breathing in some of the freshest air the planet has to offer.
