Says it effectively cools up to 700sf. I'd say that's accurate. Our house is wicked insulated, so we use it to cool the entire downstairs. It effectively removes humidity and leaves the downstairs comfortable. Cycles on and off too. Nice unit. Quiet, yet powerful. Love the different settings for when we just want the fan and not the air conditioning.

Love this item! Very hot summer, temp 90-100. Had a 10,000 and got this to replace. So quiet, seems like it's not working, but the house has stayed around 75, instead of the 85-95 with the other. Split-level home, using this in open living room/kitchen-aprox 500sqft, without an extra fan to move air!!!

I bought this for my 500 sf garage because I have my gym set up in there. It does a good job of keeping it cool when set at 75 or 76 degrees F. It's not extremely loud, less than the last window unit A/C I had (many years ago). I would give it 5 stars, but the exhaust piece that fits in the window isn't engineered as well as it could be for a good fit. I just used some tape. The little strip they give you doesn't do that much. Still, it was a good buy and has worked for about 1 month.

Luckily we only needed this portable ac unit for a week while we waited for a new ac unit for the house, but it worked perfectly. We used it in our master bedroom and vented it out the doggie door. The size was big for the room but least we were cool while sleeping.

Works well, does what it says. We've had it less than a month. Put it in sons room on 3rd floor that faces full sun all day, later over 100 degree heat index. Works great so far, I have a separate small temperature gauge on his dresser and he sleeps well and safely, not too hot for someone so young. Room is around 350 sq ft, 10 ft ceiling, three large windows.

It didn't get a 470sq ft room as cool as the air conditioner that I already had. My first air conditioner is 12000 BTU's.

I have this in the first floor of a huge 100 year old house with very little insulation. It cools most of the first floor

It worked beat at night but during the day it didn't work great unless you were directly in front of it.

Does not cool the room, Does not come with hose for condensation , or drip tray. Not worth it for the price

nice unit but for the money it should not have a constant fan.doe not cool 700sq feet even with a low ceiling
