The LIANXIANG SC-D2303 is a 7L floor standing cool mist humidifier built for medium to large rooms. It tops up without lifting the tank, runs for a full day on one fill at low output, and keeps humidity between 45–95% automatically — with UV sterilization, a sleep mode, and touch or remote control. Whether you need steadier comfort in a bedroom, less dry air in a living room, or reliable humidity for a nursery or office, this 7L unit is a straightforward, factory-direct choice.
Key Features of the SC-D2303 7L Humidifier
Top-fill design. The 7.0L tank fills from the top — no lifting, no spilling, no unplugging. Refilling a 7L humidifier takes about a minute, and the wide opening makes the tank easy to wipe clean (which matters more than most buyers expect).
7.0L capacity with a 300 ml/h mist output. At the minimum mist level, one fill can theoretically last more than 20 hours (7.0L ÷ 0.3L/h); real run time depends on the mist level you select and the room’s temperature and humidity.
UV sterilization. The water path includes UV treatment, which helps keep the mist clean between cleanings.
Automatic humidity control. Set a target between 45–95% RH and the humidifier maintains it — it switches the mist on and off so the room stays in your comfort band instead of over-humidifying. The display shows current room temperature and humidity in real time.
Sleep mode. A dedicated sleep function dims the display and runs quietly, so the unit suits bedrooms and nurseries.
Two control modes. Touch panel plus a remote control, adjustable mist level, and a 1–12 hour timer — set it to run through the night and switch off before you leave.

Where to Use a 7L Floor Standing Humidifier
- Bedrooms — quiet sleep mode and an auto shut-off timer make it a set-and-forget solution for dry winter nights.
- Living rooms & open areas — a 7L tank means fewer refills than compact desktop units; the floor-standing height spreads mist higher into the air.
- Nurseries & kids’ rooms — top-fill design and touch/remote control keep operation simple; place the unit out of reach and set 45–60% RH.
- Offices & studios — protects wood furniture, instruments, and plants from over-dry air, and keeps occupants comfortable through heating season.
Keeping indoor relative humidity in the 30–50% range is the guidance commonly cited by health and building organizations (EPA); in practice many homes run warmer and drier in winter, and a humidistat-controlled unit like this one lets you pick the level that feels right for your space.
7L vs 10L vs 13L — How to Choose the Right Capacity
LIANXIANG makes a full line of floor-standing cool mist humidifiers, so the honest question is which size fits your room.
| Model | Tank | Best for |
|---|---|---|
| H-590 | 6L | Small bedrooms, single rooms |
| SC-D2303 (this unit) | 7L | Bedrooms to medium living spaces; top-fill convenience |
| SC-D2102 / SC-D2103 | 10–11L | Large living rooms, open-plan areas |
| SC-D2301 (child lock) | 13L | Large spaces or homes with small children |
Rule of thumb: choose the smallest tank that covers your room size — a larger tank only adds value if the mist output actually serves the space. The 7L model suits typical bedrooms and medium rooms; if you are humidifying a large open living area, step up to the 10L or 11L models. If child safety is your priority, the 13L SC-D2301 includes a child lock. Need commercial-scale output for a warehouse, greenhouse or shop? See our commercial humidifier range.
Maintenance & Cleaning
A clean humidifier is what keeps the air clean. Top-fill tanks make the weekly routine short: empty any remaining water, wipe the tank and base, and descale monthly with white vinegar or a citric solution. Follow the step-by-step routine in our guide — How to Clean a Humidifier — which covers every type and the exact weekly/monthly schedule.
