J308 Humidifier Series

Model J308

J308 is a humidifier-first unit: the tank and mist path are sized for continuous room humidification rather than short fragrance bursts, while keeping the quiet ultrasonic atomiser that the aroma range is built on.

Who It Is For

Home fragrance and wellness brands building a seasonal range
Hotel and spa groups specifying room and lobby scenting
Retail and e-commerce private-label buyers who need one platform in several finishes
Essential-oil brands adding a hardware line to an oil range

Problems It Solves

Mist output and noise vary between suppliers, so a range built from several factories does not feel like one range
Small-capacity units run dry and burn the atomiser plate without water-shortage protection
Colour and wood-grain finishes drift between production runs
Retail packaging cube drives freight cost more than the unit itself

Living room and lobby - The 400 ml, 24 V J-102 with water-shortage protection, sized for a room rather than a desk.

Retail and subscription boxes - The X mini family, where packed cube and unit cost decide whether the programme works.

How It Is Made

Manufacturing Process And Quality Control

Incoming inspection

Raw materials are tested for physical and chemical performance and supplier quality is recorded before anything reaches the line.

SMT and wave soldering

Control boards are populated on our SMT line and through-hole parts are wave soldered in house.

PCBA testing

100 percent PCBA testing before the board goes into an assembly.

Assembly

Assembly on dust-free automatic lines with a QC station at every process step.

Aging test

100 percent aging testing on finished assemblies before packing.

Packing and warehouse QA

Automatic packing, then a warehouse inspection of the packed goods before delivery.

Quality Control

IQC - Incoming Quality Control: Tests the physical and chemical performance of every raw material and records supplier quality. Materials that meet the standard go to the warehouse; those that do not are rejected.
IPQC - In-Process Quality Control: QC stations are set up at every process step on the line so that a defect is caught at the station that created it rather than at final assembly.
FQC - Final Quality Control: Finished goods are inspected to the AQL standard, or 100% inspected when the programme calls for it.
QA - Quality Assurance: Wear, tear and misuse testing, plus a warehouse inspection of the packed goods before delivery.

Certifications

Manufactured under an ISO 9001:2015 certified quality system. Product-level certification is arranged per programme and per destination market - tell us the markets and we will confirm what is held and what needs to be applied for.

Customisation

What Can Be Changed On This Model

Colour and finish	Moulded colour, wood grain, crack and solid finishes on the existing tool.
Logo and printing	Logo printing and key legends applied in the factory before packing.
Colour box artwork	Retail packaging printed to your artwork so goods land retail-ready.
Trim parts	Trim rings, light diffusers and small cosmetic parts changed at low tooling cost.
Main housing	New housing tooling where the silhouette itself has to carry the brand.
Carton configuration	Pieces per carton adjusted for the programme, with carton size and weight reconfirmed.

Use Guide

How It Is Used

Fill

Fill with clean water to the marked line. Do not exceed the stated capacity.

Add oil

Add a few drops of water-soluble essential oil to the water.

Run

Plug in and switch on. The unit is plug and play - there is no pairing step.

Timing

The 5 V models shut down automatically after four hours. The J-102 also carries water-shortage protection.

Clean

Empty and wipe the tank between oils so the previous fragrance does not carry over.
