PRODUCT DETAILS
Higher output, larger capacity and automatic humidity feedback.
EH40PB is positioned as a higher-capacity electric heated room humidifier for buyers that need more output than compact personal units. Its core story is built around measurable humidification, automatic humidity control, maintenance functions and clearly separated safety features.
750 / 300 mL/h Dual Output
High mode delivers 750 mL/h while low mode delivers 300 mL/h, both with the supplied ±20% tolerance. This gives sourcing teams two clearly defined performance levels in one 4L humidifier platform.
Automatic Humidification Mode
Automatic humidity control adds a more intelligent operating layer for buyers searching for an automatic humidifier or humidifier with humidity control.
Ambient Humidity Display
EH40PB includes humidity sensing and display, giving users direct environmental feedback. Exact display range or LO/HI thresholds should be added only if the control specification confirms them.
Sleep Mode
A dedicated sleep mode is included for household use. The page does not claim a specific noise level or separate output because neither value was supplied in the engineering specification.
1–9 Hour Timer
Timed on/off operation supports planned use and naturally addresses buyer search intent for a humidifier with timer without keyword repetition.
Magnetic Power Connection
The magnetic connection is a visible physical differentiator that should be supported by a close-up image and technical connector information in the final B2B product page.

Safety Design
Protection against low water, tipping, overcurrent and overheating.
The page presents specific safety functions rather than broad claims such as “completely safe” or medical-grade protection.
Designed to protect or stop operation when water becomes insufficient.
Helps reduce spill risk when the appliance is tilted.
Provides protection against abnormal electrical-current conditions.
Supports thermal protection alongside the specified PCB and surface-temperature limits.
During operation, tilting approximately 35–55° in the most unfavorable direction should cut power and stop the unit.

FAQ
Answers procurement teams usually need before sampling.
What type of humidifier is EH40PB?
EH40PB is a 4L electric-heated warm mist humidifier with high and low humidification levels, automatic humidification mode, humidity display and sleep mode.
What is the humidification output of EH40PB?
High mode is specified at 750 mL/h and low mode at 300 mL/h, with a supplied tolerance of +20% / -20%. These values should remain consistent across quotations, datasheets and online product content.
Does EH40PB have automatic humidity control?
Yes. The supplied function list includes automatic humidification, humidity sensing and humidity display. Exact target setpoints or switching logic should be added only after the firmware specification is confirmed.
What is the humidity sensor accuracy?
The source specification states “±10RH”. This page presents it as ±10% RH for readability, but engineering should confirm the unit, test condition and tolerance definition before publication.
How long can the 4L humidifier operate continuously?
The specified continuous operating range is approximately 5 to 12 hours. Actual runtime varies with operating mode, fill level, ambient conditions and production tolerance.
Does EH40PB have a sleep mode?
Yes. Sleep mode is included in the supplied function list. The page does not claim a dedicated sleep-mode output or a specific noise level because those values were not supplied.
Can EH40PB be positioned as a humidifier for bedroom use?
Its timer, sleep mode, child lock and automatic humidity functions can support bedroom-oriented product lines. Final positioning should still match the buyer’s intended room conditions, safety documentation and market requirements.
What does the mute function do?
A mute function is included in the supplied control list. Exact button tones or alerts affected should match the final user manual. The page does not claim “ultra-quiet” operation because no verified dB value was provided.
What is the acid cleaning function?
EH40PB includes an acid cleaning / descaling maintenance function. Approved cleaning agent, concentration, cycle and procedure should be stated only after they are confirmed in the instruction manual.
What safety functions are included?
The supplied specification includes low-water protection, tip-over spill protection, overcurrent protection, over-temperature protection and tip-over shutoff. At approximately 35–55° tilt in the most unfavorable direction, the machine should cut power and stop operation.
Does EH40PB use a magnetic power connector?
Yes. The supplied configuration uses a magnetic power connection. The final landing page should include a real close-up image and applicable electrical-safety documentation for the connector.
Can EH40PB be developed for OEM or ODM projects?
OEM/ODM feasibility can be reviewed according to project requirements, including color, logo, packaging, instruction manuals, humidity-control logic, electrical configuration and target-market compliance.
Are you an air humidifier supplier for B2B buyers?
E-come supports B2B humidifier development and manufacturing projects. Buyers can provide their target market, voltage requirements, annual forecast, certification needs and packaging specification for project evaluation.
