This is the best humidifier I have owned. Winters are very cold and dry where I live, and this humidifier has made such a difference - the output is fantastic. The top filling tank makes refilling easy, and I appreciate the easy to read display. Using distilled water (my tap water has a very high mineral content) eliminates any white dust issues, and makes it easy to clean. When I had a problem with the unit, customer service helped me promptly and went above and beyond to make sure I was satisfied. I would highly recommend this unit to make dry seasons more comfortable at home.
