A quote from the forum: QUOTE" We have a NewAir portable ac. We only have one AC and it was very loud. There’s a new accessory you can buy to quiet it down and enhance performance but it’s a bit expensive in my opinion we made one ourselves. There are some YouTube video about it that might help. There’s also a great write up here." ENDQUOTE.
