    This humidifier works very well and does exactly what I needed. The quality is excellent, and it feels sturdy and well made. It is very easy to use and simple to set up. It runs quietly, which is perfect for nighttime and daily use. The mist output is good and helps keep the air comfortable, especially during dry weather. I also like the modern and clean design — it looks nice in the room. For the price, this is a great value. It performs well, is easy to maintain, and has been working reliably. I am very satisfied with this purchase and would definitely recommend it.

    This is the perfect midsize humidifier. It has smart settings that allow you to set the ideal humidity percentage. The sleek modern design makes it easier to stomach the size. It is tall allowing it to be placed in smaller spaces easier

    So far, it puts out a really great airflow. Large tank and covers a large area. However, I've had a couple days where the humidity just constantly showed 20%. And I could not get it to do a regular true reading.

    Our home is very dry in the winter, causing many different issues. I have purchased a couple other humidifier’s which didn’t work out. Although the Costway is actually too small for the area I’m trying to humidify I can tell a difference in the humidity and the issues are less. This humidifier is very easy to use and fill and runs for a few days until it needs filled. I plan to buy another unit to help humidify the area. I highly recommend the Costway humidifier.
