PRODUCT DETAILS
Three operating levels for stronger output and longer low-output runtime.
EH30UA’s main product distinction is the addition of a dedicated sleep level alongside high and low humidification. This gives distributors and private-label buyers a clearer three-step operating hierarchy without requiring unsupported “silent” or medical claims.
High / Low / Sleep Humidification
Three output levels provide approximately 460, 280 and 130 mL/h respectively, giving buyers a broader performance range within one heated room humidifier platform.
Dedicated Sleep Mode
Sleep mode reduces humidification output to approximately 130 mL/h and lowers the listed operating-power range. No noise-level claim is made because a verified dB specification was not supplied.
1–9 Hour Timer
Timed on/off control supports planned operation and naturally addresses search intent for a humidifier with timer without repeating the phrase throughout the page.
Approx. 5.5–20H Operation
The stated continuous operating range varies with the selected humidification mode, supporting both stronger output and extended lower-output use.
Child Lock Function
Child lock helps reduce unintended setting changes and adds a practical control layer for room and bedroom humidifier product lines.
Acid Cleaning / Descaling Function
A dedicated maintenance function is included. Cleaning agent, concentration, cycle and any sanitization wording should follow the final approved instruction manual.

Safety Design
Protection against low water, tipping and abnormal current.
Safety information is stated as concrete product behavior rather than broad “safe for family” marketing language.
Includes a three-minute warning sequence followed by display-off and shutdown behavior.
Designed to reduce spill risk if the appliance is tilted.

FAQ
Answers procurement teams usually need before sampling.
What type of humidifier is EH30UA?
EH30UA is a 120V electric-heated warm mist humidifier with high, low and sleep operating levels. The supplied technical tank capacity is 2.8L, even though the model is positioned in the 3L-class product family.
What are the three humidification outputs?
High mode is specified at 460 mL/h ±20%, low mode at 280 mL/h ±20%, and sleep mode at 130 mL/h ±20%. These values provide three clearly separated output levels for different use conditions.
Does EH30UA have a sleep mode?
Yes. EH30UA includes a dedicated sleep mode with approximately 130 mL/h output and a listed operating-power range of 120–180W. No “silent” or specific dB claim is made because a verified noise test was not supplied.
Is EH30UA suitable for bedroom humidifier product lines?
Its sleep mode, 1–9 hour timer, child lock and extended operating range can support a humidifier-for-bedroom product position where the buyer’s room-size, compliance and performance requirements are compatible with the supplied specifications.
How long can EH30UA operate continuously?
The specified continuous operating range is approximately 5.5 to 20 hours. Actual runtime varies with the selected mode, fill level, ambient conditions and production tolerance.
Does EH30UA have a timer?
Yes. The product includes 1–9 hour timed on/off control, supporting planned operation for room and bedroom humidifier programs.
How does the low-water protection behave?
When low water is detected, the supplied requirement states that the low-water indicator flashes for three minutes. The display then turns off and the product enters an off state.
What is the acid cleaning function?
EH30UA includes an acid cleaning / descaling maintenance function. The approved cleaning agent, concentration, operating sequence and cleaning frequency should follow the final instruction manual.
What safety functions are built into EH30UA?
The supplied function list includes low-water protection, tip-over spill protection, overcurrent protection and tip-over shutoff. When tilted approximately 35–55° in the most unfavorable direction, the machine should cut power and stop operation.
Is EH30UA a 3L humidifier?
EH30UA is positioned as a 3L-class model, but the technical specification supplied for this version lists the water tank capacity as 2.8L. For datasheets, quotations and compliance documents, use the verified 2.8L value unless engineering issues a revised specification.
Can EH30UA be developed for OEM or ODM projects?
OEM/ODM feasibility can be reviewed according to project requirements, including color, logo, packaging, instruction manuals, voltage configuration, technical documentation and target-market compliance.
Are you an air humidifier supplier for B2B customers?
