An evaporative cooler is an indoor portable air cooler that evenly distributes cool air through the honeycomb cooling media. The dust filter cleanses the air, while the non-compressor system cools naturally and efficiently without power-hungry components. The evaporative cooler, humidifier, and fan is versatile and lightweight, making it economical as well. It can also be used as a air purifier because of its anion generator.
