I bought this 6000 BTU to replace the (5 yr old) non-functioning 8000 BTU LG portable AC for my bedroom. My room is a little smaller than the recommended square footage, but I have high ceilings (9') and this AC cools off the room pretty quickly. It's not quiet, so, if you're using it in a room w/a TV you should wear headphones. For me, it's fine and doubles as a white noise machine. It's easy to clean the filters too. There are a couple things that need improvement:Draining the water that accumulates is a pain. I can't just lift it up (it weighs 60-65 lbs) and let it drain in the tub. Rather, I have to use a low, flat receptacle to catch the water, which drains all over the floor anyway. I would also change the remote to one that lights up b/c it's difficult to see what you're adjusting in a dark room. Other than those two things, I'm happy with my purchase so far.
