Our Verdict
The Honeywell HUL520 is a compact ultrasonic humidifier with a small footprint and a lower price. This unit has a simple dial with continuous mist output. We like that it is very easy to clean, has a large tank opening, a handle for carrying, and can be cleaned with few special tools. This product has a smaller capacity than most competitors, but it will last overnight on high volume and the frequent refilling will help you keep your eye on potential mold or mineral deposits. The HUL is louder than most of the ultrasonic competition but is still relatively silent at high levels. While this unit wouldn't be a good choice for larger spaces and it requires daily refilling, it can get the job done for a friendly price most families can afford.

Performance Comparison

Ease of Cleaning
The HUL520 is one of the most accessible options to clean. This unit has a tank with a wide opening that most hands will fit in. The container is small enough to reach all sides to wipe clean without the need for a special tool. You will need a bottle brush or thinner washcloth to clean the mist tube, but the length is short, so any brush should be able to do the job.
Cleaning the smaller parts of the Honeywell likely requires a smaller straw-type brush or toothbrush.

The base is also easy to keep clean, with only one spot that requires extra attention.
The Honeywell isn't as effective at creating mist as some of the competition, but if you use it in a smaller space or close to your baby's bed, it should be adequate.

Effectiveness
This smaller Honeywell is not the most effective option in the competition for mist creations. This lower mist creation may or may not be a concern depending on your goals and the size of the space you want to humidify.
This Honeywell starts out strong with a similar output to the competition, but over time the other products increase the ambient humidity more than the HUL. At the one-hour mark, about half of the competitors had produced more moisture than the HUL520.
The dust accumulation for the Honeywell during testing is more than most of the competition and could be a good argument for using distilled or boiled water if you have hard tap water.

This unit also seems to create more white dust while operating than the competition and you might want to consider using boiled or bottled water.
The Honeywell is one of the loudest in the group, but it is still quieter than an evaporative style humidifier and is unlikely to keep anyone awake.

Noise
This Honeywell is one of the loudest ultrasonic units in the review. With a decibel reading of 45 dB, it isn't loud and isn't unlikely to keep anyone awake.
The Honeywell is easy to use with a single dial for mist level output. However, it lacks features that could make using a humidifier easier like timer and humidity level settings.

Ease of Use
This Honeywell has a continuous mist dial to control output levels that is easy to use. However, it is not programmable and lacks features that could potentially make life with a humidifier easier. This unit has continuous settings and a simple “plug and play” design. The tank has a handle for carrying, and it can sit in the sink without help for filling.
The tank opening is large, which makes it easy to fill even in a bathroom sink (above left). The tank is easy to open and fits on the base without a problem. The base is small, making this a good option if space is limited. While the tank is small, it will hold enough water to create mist all night even on the highest setting. It also has a handle on the back of the vessel, making it easier to carry and place and the base (above right).
