A large humidifier eliminates the chore of daily refills, but tank size alone does not make a unit practical to live with. In this LOMMOL JS01 humidifier review, we look closely at how its 9-liter (2.4-gallon) top-fill reservoir, automatic humidistat, four mist speeds, remote control, and 550 ft² rated coverage work together in everyday spaces. Its standout strengths are long runtime (30 to 60 hours depending on speed) and simple filter-free operation, while its tall 26.1-inch tower footprint and lack of Wi-Fi app controls are the main tradeoffs to weigh before buying.

What Is the LOMMOL JS01 Humidifier?
The LOMMOL JS01 is a floor-standing ultrasonic cool mist humidifier built for medium to large rooms up to 550 ft². While its footprint is a compact 7.4 inches square, its 26.1-inch height gives it a slender tower profile designed to sit on the floor rather than on a crowded nightstand.
Its centerpiece is the 9-liter (9,000 mL) water reservoir. That capacity supports up to 60 hours of operation on the lowest mist setting—or roughly 30 hours at the full 300 mL/h output—before needing a refill. You also get four mist speeds, an adjustable humidistat, and a 360° nozzle to aim the mist plume higher into the room.
Rather than relying on Wi-Fi pairing or smartphone apps, the JS01 keeps operation straightforward. Every setting is accessible directly on the front touch panel or from across the room using the included remote control.
Who Should Buy It?
Best For
- You want a high-capacity 9 L tank so you do not have to refill a small tabletop unit every single day.
- You need automatic humidity regulation and four mist speeds for a master bedroom, nursery, living room, or plant corner.
- You prefer physical touch controls, a handheld remote, top-fill convenience, and an aroma tray over smartphone apps.
Skip If
- You want Wi-Fi connectivity, mobile app scheduling, or Alexa/Google Assistant voice control.
- You need a short, compact humidifier that fits under low shelves or on a small bedside table.
- You specifically want a warm-mist or evaporative humidifier rather than an ultrasonic cool-mist unit.
Key Features of the LOMMOL JS01 Humidifier
9-Liter Top-Fill Tank
Holding 2.4 gallons of water, the reservoir is the JS01’s biggest practical advantage. Instead of detaching a heavy tank, flipping it upside down, and carrying it dripping from the sink, you simply remove the top cover and pour water directly in from a pitcher.
The tradeoff is vertical height. At 26.1 inches tall, it stands just over two feet high. That extra height actually helps disperse cool mist higher into the air before it settles, provided you place the base on a flat, water-resistant floor surface with open overhead clearance.
Four Mist Levels and 300 mL/h Maximum Output
The JS01 provides four selectable mist speeds topping out at 300 mL/h. Knowing the math helps you plan refills: at the maximum 300 mL/h rate, a full 9,000 mL tank will run continuously for about 30 hours. Dropping down to Level 1 or Level 2 extends runtime up to 60 hours.
At the top of the tower, a 360° rotatable nozzle lets you aim the mist plume into the center of the room and away from nearby walls, curtains, bedding, or wooden furniture.
Automatic Humidity Control
The built-in humidistat lets you dial in a target relative humidity (RH) between 40% and 90% in 5% increments. Once the onboard sensor detects that the room has reached your target, the humidifier pauses misting and automatically resumes when humidity drops below the threshold.
Before You Buy: Even though the humidistat can be set as high as 90% RH, indoor air quality guidelines from the U.S. EPA recommend keeping home humidity between 30% and 50% RH (and always below 60%). Setting indoor humidity above 60% can cause window condensation and promote mold or dust mites. For most bedrooms and living areas, a 40% to 50% target is ideal.
Noise Level and Bedroom Use
With a rated noise level below 35 dB, the ultrasonic nebulizer runs at a soft whisper comparable to a quiet library. There is no boiling element or loud mechanical fan, making it well suited for light sleepers and baby nurseries.
The unit also includes a soft night light. If you prefer a pitch-black bedroom, check the panel light controls before going to bed so you know how to dim or turn off the illumination.
Aroma Tray, Ceramic Filter, and Water Quality
The JS01 features a slide-out aromatherapy tray at the base. Adding a few drops of essential oil to the tray’s pad infuses the outgoing air with scent safely. Never pour essential oils directly into the 9-liter water tank, as concentrated oils can crack ABS plastic and damage the ultrasonic transducer.
Inside the water path, a built-in ceramic filter stone helps condition the water without requiring disposable wick filters. However, buyers should understand how ultrasonic humidifiers handle tap water: while the ceramic filter helps reduce scale inside the tank, dissolved calcium and magnesium in hard tap water can still be misted into the air and settle as fine “white dust” on dark furniture. Using distilled or demineralized water eliminates white dust and greatly reduces mineral scale buildup.
Remote and Touch Controls
You can adjust mist speed, target humidity, timer duration, and lighting either on the unit’s front touch panel or with the included handheld remote. Because tower humidifiers sit on the floor across the room, having a physical remote on your nightstand saves you from getting out of bed to tweak the output.
Keep in mind that the remote is line-of-sight rather than Wi-Fi based. If you want to monitor room humidity from work or trigger schedules via voice assistants, consider a smart-enabled alternative instead.
What to Expect in Everyday Use
For Overnight Bedroom Use
Sub-35 dB operation, a 9-liter tank, automatic shutoff when empty, and a bedside remote make the JS01 easy to live with overnight. Setting the humidistat to 45% or 50% RH on Mist Level 1 or 2 maintains comfortable air through the night without over-saturating the room or requiring daily morning refills.
For Larger Rooms
LOMMOL rates the JS01 for spaces up to 550 ft². In an enclosed bedroom or medium living room, 300 mL/h of output can raise humidity steadily. In open-concept layouts with high ceilings, open doorways, or active central heating, moisture disperses across a much larger air volume, so you will likely need Mist Level 3 or 4 to see a noticeable jump on your hygrometer.
For Plant Areas
Tropical houseplants such as monsteras, calatheas, and ferns thrive when relative humidity stays between 50% and 60% RH. The JS01’s 26.1-inch height and 360° nozzle allow cool mist to drift gently over a plant grouping. Always aim the nozzle into open air slightly away from foliage so water droplets do not pool directly on leaves or soil.
For Long-Term Daily Use
Skipping monthly replacement filter cartridges keeps ongoing ownership costs close to zero, and the 30-watt power draw uses very little electricity. Even so, a 60-hour tank capacity is not an excuse to let water sit stagnant for a week—emptying leftover water every couple of days keeps the mist fresh and hygienic.
Setup and Placement Tips for Better Results
- Place on a flat, water-resistant floor or low stand: Keep the tower level on tile, sealed flooring, or a waterproof mat so stray mist or refill drips cannot damage wood or carpet.
- Give the tower breathing room: Leave at least 12 to 18 inches of clearance from walls, curtains, bedding, and electronics.
- Aim the 360° nozzle toward open space: Direct the mist plume toward the center of the room where air circulation can evaporate it evenly.
- Set a realistic humidity target (40%–50% RH): Start at 45% RH on Mist Level 2 and let the automatic humidistat cycle the output as needed.
- Use distilled or filtered water if you have hard tap water: Distilled water prevents white mineral dust on furniture and keeps the ultrasonic transducer clean longer.
- Keep essential oils strictly in the aroma tray: Apply oils only to the dedicated aroma pad, never into the top-fill water reservoir.
Pro Tip: Built-in humidistats sit right next to the humidifier base, where the air is naturally more humid than the rest of the room. Place an inexpensive standalone hygrometer near your bed or sofa, and set the JS01’s target 5% higher if needed to match your across-the-room reading.
Cleaning and Maintenance
Even with a large 9-liter tank and a ceramic filter, regular water care is essential for any ultrasonic humidifier. Empty any standing water every two to three days, rinse the reservoir, and let surfaces dry if you plan to store the unit unused.
Unplug the humidifier before cleaning. Once a week (or every two weeks if using distilled water), descale the base chamber and water tank according to the user manual, using the included cleaning brush to gently loosen mineral deposits around the transducer and mist chute. Never scrape the ultrasonic disc with metal or abrasive tools.
Rinse the built-in ceramic filter periodically under clean running water to flush out trapped sediment. Keeping up with basic rinsing prevents musty odors and preserves full mist output over the life of the machine.
Pros and Cons
Pros
- Generous 9 L (2.4-gallon) top-fill reservoir cuts down on frequent refilling

Is It Worth the Price?
The LOMMOL JS01 delivers strong value if your top priorities are multi-day water capacity, automatic humidity control, top-fill convenience, and a physical remote. Instead of paying extra for Wi-Fi chips and cloud apps, your budget goes toward a larger 9-liter reservoir that handles bedrooms and living spaces with minimal babysitting.
Its filter-free ceramic design also saves money over time compared with evaporative humidifiers that require new wick filters every one to three months. As long as you commit to routine rinsing—and use distilled or filtered water if your tap water is hard—the ongoing cost of ownership stays very low.

Frequently Asked Questions
Can you use essential oils with the LOMMOL JS01?
Yes. The JS01 includes a dedicated pull-out aromatherapy tray. Add a few drops of essential oil only to the aroma pad inside that tray rather than pouring oils directly into the 9-liter water reservoir.
How large is the LOMMOL JS01 water tank and how long does it run?
The tank holds 9 liters (about 2.4 gallons or 9,000 mL). At the maximum 300 mL/h mist speed, a full tank runs continuously for about 30 hours; on the lowest mist setting or when cycling with the automatic humidistat, runtime extends up to 60 hours.
Is the LOMMOL JS01 suitable for a large room?
It is rated for spaces up to 550 ft². Real-world humidity gains depend on ceiling height, room layout, HVAC airflow, starting humidity, door position, and your chosen mist speed.
Does the LOMMOL JS01 need replacement filters or distilled water?
The JS01 uses a built-in ceramic filter that does not require routine disposable filter replacements. However, if you have hard tap water, using distilled or demineralized water is recommended to prevent ultrasonic “white dust” on furniture and minimize mineral scale inside the unit.
How much electricity does the LOMMOL JS01 use?
The humidifier is rated at 30 watts at 110 volts. Running it continuously for 8 hours overnight uses just 0.24 kWh of electricity (or 0.72 kWh over a full 24 hours), and even less when the automatic humidistat cycles the mist off.
How often should you clean the LOMMOL JS01?
Empty and rinse residual water every two to three days so water never sits stagnant, and perform a full tank and base cleaning once every one to two weeks following the manufacturer’s manual.
Who should skip the LOMMOL JS01?
Skip it if you specifically need warm mist, Wi-Fi smartphone app control, voice-assistant integration, or a small tabletop humidifier. Its 26.1-inch height is designed for floor placement with adequate overhead clearance.
The Bottom Line
The LOMMOL JS01 is a practical, well-rounded choice when you want a high-capacity 9-liter cool-mist humidifier with automatic humidity regulation, four mist speeds, whisper-quiet under-35 dB operation, and a remote control. Its main compromises are its 26.1-inch floor-tower height and lack of Wi-Fi smart controls—so if you have the floor clearance and prefer simple, filter-free operation with fewer refills, the JS01 is well worth considering.
