Manufactured in 2022. I purchased this but didn't use it because the humidity in my room was high. It has just been sitting in the room. I am selling it due to a move. I have only tested its operation by putting water in it. The filter is clean. Includes the main unit, instruction manual, and power adapter. No box.
