The Skinny

The Honeywell HUL520 is a compact ultrasonic humidifier with a small footprint and an inexpensive price. This unit has a simple dial with continuous mist output settings. We like that this unit is very easy to clean, has a large tank opening and handle for carrying, and can be cleaned with few if any special tools. This product has a smaller capacity than most of the competition, but it will last overnight on high volume and the frequent refilling will help you keep your eye on potential mold growth 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 can't be used for days without refilling, it does get the job done for a very friendly price most families can afford.

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. The base is also easy to keep clean, with only one spot that requires extra attention.

The top of the HUL520 has a single mist output hole that is not adjustable. The entire unit needs to be moved to redirect the mist away from walls and other undesired locations.

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 stars 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.

Noise


This Honeywell is the second loudest ultrasonic unit in the review. The evaporative humidifier is the loudest with a decibel reading of 60.


With a decibel reading of 46 dB, only it isn't loud, and it is unlikely to keep anyone awake.

The Honeywell has a variable mist output dial that is easy to use but lacks programmable features.

Ease of Use


This Honeywell has a continuous mist dial to control output levels. However, it is not programmable and lacks features that could potentially make life with a humidifier easier, which impacted its ease of use score.


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 on the HUL520 has a large opening that is good for cleaning and makes filling it a snap.

The tank opening is large, which makes it easy to fill even in a bathroom sink. 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.
