One drawback is the absence of a built-in humidistat, which means there is no automatic regulation of humidity levels. Additionally, it is not recommended to add essential oils, which could be a limitation for those looking to enhance the room with fragrances. Despite these minor drawbacks, the LEVOIT Top Fill Humidifier has a user-friendly design, quiet operation, and effective humidification, making it a strong choice for parents looking to improve air quality in their child's room.

On the downside, some users have mentioned that the humidifier may require regular cleaning to prevent mold and buildup, which might be a hassle for busy parents. Additionally, while it has a filter, it’s important to note that it may need to be replaced periodically, which can add to the ongoing cost of maintenance. The unit is compact, but its rounded shape might make it less stable in households with curious toddlers.

Another positive feature is the auto shut-off function that ensures safety when the water level is low. This is especially important in homes with children.
