A large humidifier can cut down on constant refills, but capacity alone does not make one easy to live with. The LOMMOL JS01 combines a 9-liter (2.4-gallon) top-fill tank with adjustable humidity control, four mist levels, a remote, and coverage rated for rooms up to 550 ft². Its main strengths are long runtime and straightforward controls, while its tall 26.1-inch design and lack of smart app control may matter to some buyers. This review breaks down where the JS01 fits well and what you should know before choosing it.
Quick Verdict
Rating: 8.5/10
Best For: Bedrooms, living rooms, nurseries, plant rooms, and other spaces where you want a large tank with automatic humidity control.
Bottom Line: The LOMMOL JS01 offers strong capacity, up to 60 hours of runtime, and useful automatic controls without requiring replacement filters. Its tall footprint and lack of app-based smart controls make it less suitable for buyers who want a compact or connected humidifier.

Key Takeaways
- The 9-liter tank is much larger than the tanks used in many bedside humidifiers, reducing how often you need to refill it.
- Four mist settings and up to 300 mL/h output give you more control over moisture delivery.
- The built-in humidistat lets you select a target between 40% and 90% RH, although higher selectable settings do not mean higher indoor humidity is always advisable.
- Noise stays below 35 dB according to the product specifications, making the JS01 suitable for sleep-focused spaces.
- The 360° nozzle, remote control, top-fill tank, timer, and automatic shutoff make everyday operation easier.
- A dedicated aroma tray supports essential oils without requiring you to put oil directly into the water tank.
- The built-in ceramic filtration design does not require routine replacement filters, but the humidifier still needs regular cleaning.
What Is the LOMMOL JS01 Humidifier?
The LOMMOL JS01 is a floor-standing ultrasonic cool mist humidifier designed for spaces up to 550 ft². Its narrow base measures roughly 7.4 inches square, while its 26.1-inch height gives it more of a tower-style profile than a compact bedside humidifier.
The main attraction is its 9-liter reservoir. That tank supports a claimed maximum runtime of up to 60 hours, depending on operating conditions and mist output. You also get four mist levels, a maximum mist output of 300 mL/h, adjustable humidity control, and a 360° nozzle for directing mist.
It is designed for buyers who want fewer refills without moving to a complicated smart-home system. Controls are handled through the touch panel or included remote rather than an app.
Who Should Buy It?
Best For
- You want a large tank so you do not have to refill a small bedside unit every day.
- You need automatic humidity control and several mist settings for a bedroom or larger living space.
- You value a remote, top-fill access, directional mist, and an aroma tray more than app connectivity.
Skip If
- You need Wi-Fi, app control, voice-assistant integration, or remote monitoring.
- You want a small humidifier that can sit easily on a crowded nightstand.
- You specifically need warm mist rather than an ultrasonic cool mist design.
Key Features of the LOMMOL JS01 Humidifier
9-Liter Top-Fill Tank
The 2.4-gallon capacity is the JS01’s most obvious practical advantage. A larger tank means less frequent refilling, particularly when you use a lower mist setting. The top-fill design also lets you add water without turning a heavy reservoir upside down.
The tradeoff is size. At roughly 26.1 inches high, this is not a tiny tabletop model. Before buying, decide where you can place a tall humidifier on a stable, water-resistant surface.
Four Mist Levels and 300 mL/h Maximum Output
The JS01 offers four mist-output levels, topping out at 300 mL/h. Lower settings can make sense for overnight use or smaller rooms, while a higher output can raise humidity faster when the room is dry.
The 360° nozzle is helpful because you can direct the plume away from nearby walls, furniture, curtains, and electronics instead of accepting one fixed direction.
Automatic Humidity Control
The humidistat allows a target setting from 40% to 90% RH in 5% steps. Once the selected level is reached, automatic humidity control can reduce unnecessary misting and restart when the measured humidity drops.
Before You Buy: The fact that the control can be set as high as 90% does not mean you should maintain your home at that level. Excess humidity and visible condensation can encourage moisture problems. Lower the output or target setting if windows, walls, or nearby surfaces become damp.
Noise Level and Bedroom Use
The listed operating noise is below 35 dB. That makes the JS01 a reasonable option for bedrooms, nurseries, and other areas where a loud appliance would be distracting.
You also get a night-light function. If light bothers you while sleeping, check the display and lighting settings before settling in for the night rather than assuming every illuminated feature will turn off automatically.
Aroma Tray and Ceramic Filter
The JS01 includes a dedicated aromatherapy tray. That is an important detail because essential oils should be used with the intended aroma component instead of being poured directly into the water tank unless the product instructions specifically say otherwise.
The humidifier also uses a built-in ceramic filtration component that does not call for regular replacement filters. This reduces the need to buy disposable filter cartridges, although mineral deposits can still build up inside an ultrasonic humidifier and routine cleaning remains necessary.
Remote and Touch Controls
You can adjust the unit from its control panel or with the included remote. For a floor-standing humidifier used beside a bed or across a larger room, the remote is more than a novelty because it lets you change mist output or other settings without walking over to the unit.
The main limitation is connectivity. The JS01 is not positioned as an app-controlled smart humidifier, so buyers who want schedules and remote control from a phone should compare smart alternatives.
How It Performs in Real Use
For Overnight Bedroom Use
The combination of under-35 dB operation, a large reservoir, automatic humidity control, and remote operation fits overnight use well. You can start with a lower mist setting and let the humidistat manage output instead of running maximum mist continuously.
For Larger Rooms
The manufacturer-listed coverage is up to 550 ft². Actual results depend on room layout, ventilation, temperature, starting humidity, open doors, and the amount of air moving between spaces. One enclosed room is generally easier to humidify consistently than several connected rooms.
For Plant Areas
The directional nozzle and adjustable output can be useful when the humidifier shares a room with houseplants. Avoid aiming a concentrated plume directly at leaves, walls, windows, or furniture where moisture could collect.
For Long-Term Daily Use
The larger tank and no-replacement-filter design reduce two common inconveniences: frequent refills and recurring filter purchases. Cleaning is still part of ownership, though. Long runtime should not be treated as permission to leave old water standing indefinitely.
Setup and Placement Tips for Better Results
- Use a stable surface: Keep the humidifier upright on a firm, flat, water-resistant location.
- Leave clearance: Avoid pressing the humidifier against a wall, appliance, curtain, or other moisture-sensitive surface.
- Direct the nozzle carefully: Use the 360° nozzle to send mist into open room air rather than directly onto furniture or electronics.
- Start conservatively: Begin with a moderate humidity target and mist level, then adjust according to actual room humidity.
- Watch for condensation: If windows or nearby surfaces become wet, lower the humidity target or mist output.
- Use the aroma tray correctly: Keep essential oils out of the water reservoir unless the manufacturer’s instructions specifically direct otherwise.
Pro Tip: Use a separate hygrometer elsewhere in the room when you first set up the humidifier. Comparing that reading with the humidifier’s sensor can help you understand how evenly moisture is spreading through your space.
Cleaning and Maintenance
A large tank does not remove the need for frequent water care. Empty stale water, keep the tank and water-contact surfaces clean, and follow the cleaning procedure in the supplied manual. If you have hard water, mineral scale may appear more quickly in the tank or around the ultrasonic components.
Before cleaning, unplug the unit. Pay attention to the tank, mist outlet, and areas where mineral deposits are visible. The included cleaning brush can help with accessible buildup, but avoid scraping delicate ultrasonic components with hard or sharp tools.
The ceramic filter reduces the need to purchase replacement filters, but it should not be confused with a maintenance-free design. Water quality and cleaning habits still influence buildup and odor over time.
Pros and Cons
Pros
- Large 9 L / 2.4-gallon top-fill reservoir
- Up to 60 hours of stated runtime
- Four mist settings with up to 300 mL/h output
- Automatic humidity control with an adjustable humidistat
- Remote, 360° nozzle, aroma tray, night light, and automatic shutoff
Cons
- The 26.1-inch height requires more vertical space than a compact bedside unit.
- No app or smart-home control is listed for this model.
- A large tank still requires regular water changes and cleaning.
Is It Worth the Price?
The JS01 makes the strongest value case for buyers who will actually use its large tank, humidistat, four mist speeds, remote, and long-runtime design. Those features can be more useful in a bedroom or larger room than paying for app functions you may never use.
Its no-replacement-filter design can also reduce an ongoing ownership expense. You should still factor in cleaning and water quality, because an ultrasonic humidifier needs maintenance even when it does not use disposable filters.
It is less compelling if your main priorities are compact size, warm mist, or smart-home integration. In those cases, buying a different feature set may provide better value even if the competing unit has a smaller tank.
How It Compares to Alternatives
The Levoit Classic 300S is worth comparing if app and voice controls are important to you. It uses a smaller 6-liter tank but adds smart connectivity. The LOMMOL JS01 instead gives you a larger 9-liter capacity and conventional remote/touch operation.
The Dreo HM713S is another option for buyers who specifically want both cool and warm mist plus app control. The LOMMOL is the simpler choice when your priority is a large cool-mist reservoir, straightforward humidity control, and fewer connected features.
Warranty and Support
Product information for the JS01 lists a one-year warranty and a 120-day free replacement policy. Support information also advertises seven-day-a-week assistance.
Because warranty procedures can depend on the seller and purchase channel, keep your order information and confirm the current warranty terms shown with the product before you buy. That is particularly useful if the item is being sold by a marketplace seller rather than directly by the brand.
Frequently Asked Questions
Can you use essential oils with the LOMMOL JS01?
Yes, the JS01 is listed with a dedicated aromatherapy tray. Use essential oil only through the intended aroma component and follow the supplied instructions rather than pouring oil directly into the main water tank.
How large is the LOMMOL JS01 water tank?
The tank holds 9 liters, or about 2.4 gallons. That large capacity supports a stated maximum runtime of up to 60 hours, although actual runtime changes with mist level and room conditions.
Is the LOMMOL JS01 suitable for a large room?
It is rated for spaces up to 550 ft². Real performance depends on the room layout, ventilation, temperature, starting humidity, door position, and selected mist output.
Does the LOMMOL JS01 need replacement filters?
The unit is listed with a built-in ceramic filtration component that does not require routine replacement filters. You still need to clean the humidifier and remove mineral buildup as needed.
How much electricity does the LOMMOL JS01 use?
The listed electrical rating is 30 watts at 110 volts. Your total electricity use depends on how many hours per day the humidifier operates and how often its humidity control cycles the mist on and off.
How often should you clean the LOMMOL JS01?
Do not let water remain stagnant in the tank for long periods. Clean water-contact surfaces regularly and follow the manufacturer’s cleaning instructions, especially when you see scale, film, or residue.
Who should skip the LOMMOL JS01?
Skip it if you specifically need warm mist, app control, voice-assistant support, or a very compact nightstand humidifier. Its 26.1-inch height is better suited to a dedicated floor or raised-surface location with adequate clearance.
The Bottom Line
The LOMMOL JS01 is a strong fit when you want a large 9-liter cool-mist humidifier with automatic humidity control, four output levels, quiet operation, remote control, and fewer refills. Its biggest limitations are its tall physical design and lack of smart app control, so buyers who need compact sizing or connected features should compare alternatives first.
