Is it good for the environment?
Conventional air conditioners cause dry air to use chemicals that can harm the environment if it is released into the atmosphere. Refrigeration by evaporation, however, is based on a totally natural process of air cooled by water, which means it does not dry the air, does not irritate the skin, throat, or eyes and does not affect the environment.
Evaporative cooling is one of the healthiest ways to cool down because it replaces stale air with clean, fresh air in a very short time. Remember that you will keep your doors and windows open, the air is renewed, removes bad odors and germs airborne.
