I was highly, highly impressed with this humidifier. It was the best humidifier I have had to date and I have had a lot over the years. The big tank is amazing and helped it last well through the night and beyond. Most humidifiers I have had in the past I have had to refill every single night but not this one. I liked that you could adjust the spray level to and have it blow more or less depending on your needs. I had a really bad cough for over a week and this helped the air quality be better with the wildfires too that we were experiencing. It really helped me get better sleep and I liked that you could turn on a blue light too for ambiance.
