This is my 2nd unit, I bought one last year for our bedroom and it's amazing!! So quiet first few time I had it one I actually had to walk up to it to see if it was still running, so impressed, I bought another one this year for our living/dining area. I didn't want to listen to a noisy A/C unit, this is definitely the way to go!!!  If I needed a 3rd unit, this is what I'd buy!
