I can’t sing the praises of this device enough. It’s amazing. It is a must have. It is sooooo quiet and it makes the house smell super fresh. I was so excited to get this delivered and we love it. It gets rid of all the yucky smells in the house and the air is at a nice quality. I have been sleeping a lot better and not coughing at night with a dry throat. I can’t wait to see what other benefits we are going to get from it. Grab it!!! You’ll be happy.
