KokoHie R5 CCH-R5WS Antibacterial Plus Purchased 3/23/2024 Receipt & Warranty Included Used 2-3 times, but I received a large evaporative cooler from a friend, so I'm selling this. One anti-mold and antibacterial filter is installed in the unit and ready to use. The other is unused. There is some minor damage on the back of the instruction manual.
