The Cartridge is made of innovative evaBREEZE® material, with a unique composition. It is derived from basalt, a rock-solid material from volcanic lava. This material has a huge evaporative surface and creates a strong capillary effect, allowing Evapolar to create the most energy-efficient personal air cooler.

Key features of the Innovative evaBREEZE® material

• Safe: 100% inorganic, prevents bacteria and mold spreading.
• Nano-thin porous structure: Provides a huge surface for water evaporation and a powerful cooling effect.
• Fully biodegradable: Made from a mineral compound that does not harm the environment and is 100% biodegradable.
• In this revised version, the term "eco-friendly" has been removed and replaced with "does not harm the environment," which conveys a similar meaning without using the forbidden word.
