Arctic Air turns cold water, via a special filter, into cooler, cleaner air. It humidifies, cools and even helps to reduce smoke and dust from your personal breathing space so you can stay cool and breathe clean, cool air wherever you need it. From the bedside to the office, Arctic Air helps to keep your personal space nice and cool. Using no chemicals or toxic coolants, Arctic Air takes ordinary water absorbed into a special filter, then, using evaporative air cooler technology, it filters the hot, dry air in your room to emit cooler, moist, cleaner air. Simply fill with water, plug it into any standard wall socket or USB port and enjoy!
