After researching more than I should have... I finally decided to purchase this humidifier for my office/plant room and I love it! I have had it since May 2020 and have had zero issues. It is easy to fill and will run for a few days for me at 55% (the range is 30 to 80 at increments of 5%) and putting out the minimum humidity (there are three levels - low/med/high). Keep in mind that everyone's house, or apartment, etc., is different so it may run differently for you. It auto runs, is very quiet, and will let you know when it runs out via a few beeps. I would highly recommend this to anyone who is looking for a bigger humidifier who either has plants or just wants it for personal use.
