Evapolar's Evaporative Cartridge is part of the Evapolar Air Conditioner & Humidifier and needs to be replaced every 3-6 months to maintain Evapolar's cooling capacity.

The cartridge material is a compound of natural basalt fibers, which has a huge evaporative surface and creates a strong capillary effect, allowing Evapolar to create the most energy efficient personal air conditioner. The material filters out dust from the air and prevents mold and bacteria from growing inside, while remaining eco-friendly and fully biodegradable.
