Review on Portable Rechargeable Evaporative Air Cooler - 3-in-1 Mini USB AC 🌬️ Fan, Sterilizer & Humidifier, Desktop Cooling Fan with 3 Speeds for Home Office by Destiny Gvozdeva

It was interesting to try this. I loaded everything and left. Put some ice chips on the ground with cold water. The filter absorbs water and a fan behind the filter forces air through the wet filters to cool the air before it hits you. Barely cools your face when you stand directly on it. If you're trying to stay cool during the heat, this won't help you.
