I live in Arizona and it's an extremely dry climate. This unit has great reviews so I decided to purchase it. I put it together last night and I couldn't believe how silent it was. I set it up near my bed and let it do its job. I woke up the next morning very refreshed and felt like I had one of the best night sleeps in a long time. I'm extremely satisfied so far! It's a wonderful product and I highly recommend. Go get it!
