There are a few considerations to keep in mind. While the humidifier effectively raises humidity levels quickly, it may require regular cleaning and filter replacements to maintain optimal performance over time. Some users might find the cleaning process a bit tedious, though it’s necessary for longevity. Additionally, while it covers a decent area, those looking to use it in very large rooms might need to consider a more powerful option.
