This humidifier is really good! The only improvements I would suggest would be that I was a bit surprised at how low down the maximum water line was for the size of the machine itself. I wish there was an option to just use it as a purifier. All in all the set up was quite easy as was filling it and measuring the salt. The water runs out a bit fast IMO for the size of the machine so I would have probably preferred a purifier. It's a great looking device and does make the air feel cleaner.
