Evapolar's Stormy Gray evaSMART is an intelligent personal evaporative air cooler with smart home and mobile app control, removable water tank, and full-spectrum LED light. Engineered as a 3-in-1 cooling device, it cools, purifies, and humidifies the air. It has a sleek minimalist design, sophisticated functionality, and powerful cooling. evaSMART is fully compatible with Alexa® and Google Home™ and can be remotely controlled via mobile app, making it ideal for taking care of your pets and kids while you're away. Created to cool down the personal area only in front of you, the evaSMART air cooler won't waste tons of energy trying to cool the whole room. Powered by unique evaBREEZE technology, the air cooler can decrease outcoming air temperature up to 44.6°F to 50°F, depending on the humidity level. This portable and USB-powered smart air cooler is ideal for sleeping, resting, and working in the office and from home. Just add water, connect the device to power (an electricity source—a socket, a power bank, a laptop, etc.), and enjoy the fresh air. You can control the airflow and the LED lighting via the device's touchscreen, smart assistants, or the mobile app. Breathe pure and fresh air, thanks to the long-lasting biodegradable basalt fibers inside the cartridge. They filter out the dust in the air and retain water for more efficient cooling and humidifying.
