Key differences
| Aspect | Honeywell 1.1-Gallon Cool Moisture Humidifier | Levoit 3L Smart Top-Fill Humidifier |
|---|---|---|
| Technology | Evaporative | Ultrasonic (implied by cool mist/smart features, not explicitly stated but standard for this form factor; however, strict rule says only use facts. Levoit data says 'Cool Mist' and 'Smart'. It does not state evaporative. I will write 'Smart / Ultrasonic-style' or just 'Cool Mist technology'. Better to stick to explicit: Levoit does not list evaporative. Honeywell does. Levoit has 'auto mode' via sensor. |
| Technology | Evaporative | Cool Mist (Smart) |
| Control Method | Manual | App |
| Tank Capacity | 1.1 Gallon | 3 Liters |
| Filter Requirement | Wicking filter | Not listed |
| Fill Design | Side fill | Top fill |
Which one should you choose?
Choose Honeywell 1.1-Gallon Cool Moisture Humidifier if
- You want evaporative technology that uses a wicking filter to capture minerals.

Verdict: The Honeywell is the better choice if you value evaporative filtration and UV water treatment for cleaner mist.

Honeywell vs Levoit Humidifier Showdown
Humidification technology
The Honeywell HCM350B uses evaporative technology, which relies on a wicking filter to absorb water and release it as cool mist. This method naturally filters minerals from the water, reducing white dust on surfaces. It also includes UV technology to help treat the water before it becomes mist. The Levoit LUH-D301S is a cool mist humidifier, but the data does not specify if it uses an evaporative filter or an ultrasonic mechanism. If it is ultrasonic, it may release minerals into the air. The Honeywell approach is generally better for avoiding mineral dust, while the Levoit method may produce a finer, cooler mist depending on its internal mechanism.
Smart control features
The Levoit LUH-D301S is a smart humidifier that connects to the VeSync app. You can adjust humidity levels, set schedules, and use an auto mode with a built-in humidistat from anywhere. It also allows you to add essential oils for fragrance. The Honeywell HCM350B has no mentioned app connectivity or smart sensors. It relies on manual operation and a large tank for overnight use. If you want remote control, scheduling, and precise humidity maintenance via a smartphone, the Levoit is the clear choice. The Honeywell is a traditional, non-connected device.
Tank capacity and runtime
The Honeywell features a 1.1-gallon tank, which provides up to 24 hours of runtime. This large capacity is ideal for overnight use in a bedroom without needing a refill. The Levoit has a 3-liter tank, which converts to approximately 0.79 gallons. While the Levoit tank is substantial, the Honeywell’s gallon-based capacity is larger. The Honeywell also states it can run all night, providing consistent moisture. The Levoit’s smaller tank may require more frequent refilling for long-term continuous use, though its top-fill design makes refilling easier. For pure volume, the Honeywell holds more water.
Fill design and maintenance
The Levoit LUH-D301S features a top-fill design with a large opening. This allows you to fill the tank without lifting or turning it over, making it easier to handle and clean. The Honeywell HCM350B has a self-standing tank that is easy to fill, but it does not specify a top-fill mechanism. All parts of the Honeywell that touch water are dishwasher safe, which simplifies cleaning. The Levoit’s design is more convenient for daily refilling, especially if the unit is placed in a tight spot. However, the Honeywell’s dishwasher-safe parts offer a different cleaning advantage.
Physical footprint and weight
The Honeywell HCM350B is larger and heavier, measuring 13 inches by 10.3 inches by 18.5 inches and weighing 9 pounds. It is designed for medium rooms. The Levoit LUH-D301S is more compact, measuring 7.09 inches by 7.09 inches by 11.8 inches and weighing only 3.09 pounds. The Levoit is significantly lighter and takes up less floor or table space. If you have limited space or need a portable unit, the Levoit is better. The Honeywell is bulkier but may offer more stability due to its weight.
Which humidifier matches your needs
You want easy filling and smart control
The Levoit LUH-D301S-WUS features a top-fill design, so you do not need to lift the heavy tank. Its 3-liter capacity supports longer operation. You can adjust settings via the Vesync app. The built-in humidistat maintains your target humidity level automatically without manual checks.
You prefer natural filtration and quiet operation
The Honeywell HCM350B uses evaporative technology with a wicking filter. This method captures minerals to reduce white dust. It also includes UV technology for cleaner mist. The fan-like sound is gentle for bedrooms. The 1.1-gallon tank runs for up to 24 hours on a single fill.
You need a compact unit for small spaces
The Levoit measures 7.09 by 7.09 by 11.8 inches and weighs only 3.09 pounds. This small footprint fits easily on nightstands or desks. The white color blends into most bedroom decor. Its smart features allow you to control it remotely via your phone.
