Rating : - Wonderful machine
We've had this model for about a year now. It's a high quality product. Even on the highest setting, it's still softer than our cool mist vaporizer on its low setting. The warranty is unbeatable. It's super easy to care for. The filter is very accessible. My husband has terrible sinus problems and this machine has been keeping him medication free since we purchased it. You can sign up for an automatic filter replacement program where the new filter is delivered automatically when it's time to change (every six months is recommended in order to maintain the 10 year warranty). It's costly, but worth it compared to the junk that you can buy in an average retail store. You can tell as soon as you open it that it's built to last.
