With a generous tank capacity of 6 liters, it can run for up to 60 hours on a single fill, making it a practical choice for continuous use without frequent refills. The 360° rotating nozzle helps distribute moisture evenly, which is great for bedrooms, offices, and even plant care. Its three mist settings allow users to customize the humidity level according to their needs, which is particularly beneficial if you're sensitive to humidity changes.

In terms of safety, it incorporates an anti-dry burn feature that shuts off the humidifier if the water level gets too low, providing peace of mind for users. The top-fill design simplifies the refilling process, ensuring you won’t struggle with awkward angles when adding water. However, there are some drawbacks to consider. While the noise level is generally quiet, some users might find it slightly louder than expected during operation. Additionally, while the essential oil diffuser is a thoughtful addition for those who enjoy aromatherapy, it requires some maintenance, including cleaning the atomizing sheet with a soft brush, which might be a hassle for some.

It also includes a feature for essential oil diffusion, enhancing the room's ambiance with pleasant scents.

It’s important to note that while the smart features are beneficial, they may be a bit overwhelming for users who aren't as familiar with technology. Additionally, the cleaning process requires some handwashing, which might be less convenient for some.
