Review on 🌬️ Stay Cool Anywhere with MOVTIP Portable Air Conditioner Fan - Black: Mini Evaporative Cooler for Personal Space, Home Office, and Bedroom by Jennifer Kiel

All "evaporative coolers" work by adding extra moisture to the air. This extra moisture from the ice and water you load into this unit will evaporate and effectively cool a small area EXCEPT and ONLY when the air in your location is not humid. But if you live where the average humidity is already over 50%, this device doesn't cool any better than a small fan. In fact, adding extra moisture can increase the "moss" feel in high humidity areas. To recap, if like me you live in a place with low average humidity (Colorado), this will cool a small area. If you live in high humidity areas like Seattle or Florida, these and all evaporative coolers won't work for you. Hope that helps.
