PSOS Dehumidifier/1000 Sq. Ft (Open Box)

Edit: Doesn't even handle humidity inside a 2x4x6 grow tent. Pathetic toy really. Its tank doesn't hold 120 oz, at best it holds 60. It's supposed to cover an area of 1000 sq ft, but it's been running all day (6 hours now) since this morning in my 130 sq ft home office and it has not made a dent on the humidity. It was at 63% this morning, and it's now at a whooping 62%. Don't know if got a defective unit but I feel scammed to be honest, more so considering I only started using it when the humidity went north of 60%, and by then I was already outside the return window. Do not waste your hard earned money in this. No, I'm not covering any of its sides, it has plenty of room to intake and exhaust air, and there's a tower fan circulating the air around the room as well. Also, the door remains closed, so something is clearly wrong with this unit, or I just got scammed. Didn't rate 0 stars because there is no option.
