wet towels. re wet every day or place part of them in a bucket of water. but change water daily. and change towel every 3-4 days and wash it on hot with vinegar or the minerals will turn it crispy. Could also use RO water or distilled to avoid minerials.

blow air across water.. anything that absorbes water and increases surface area of what the fan hits will improve effectiveness.. . this is the same way a basic evaporative cooler or humidifier works. A wick draws water up, air is forced through the wick (increased surface area). Be sure to swap out whatever you use often and launder it or otherwise disinfect it. Gonna constantly grow shit after a few days.
