Summer’s here, so you have to be prepared to face a few heat waves. While air conditioners can help you keep cool, they're not typically eco-friendly, and you can't exactly bring them with you. However, there's a non-toxic and compact option to stay seriously cool this summer: the EvaPolar evaLIGHT air conditioner.

Engineered to be ten times more efficient than other portable AC units, this device uses a natural evaporative effect to cool the air around you, covering a three to four meter radius. It can decrease the temperature in your space by nearly 65°F, while also humidifying and filtering dust particles to improve overall air quality.

Unlike typical AC units, the evaLIGHT consumes just ten watts of electricity and doesn't use Freon-like liquids that harm the environment. Plus, it works via USB power supply, allowing you to use it everywhere you go. This portable AC unit is usually $199, but you can get it on sale today for $149.
