MOQ is 200 units per SKU with a 25-35-day lead time, FOB Shenzhen or EXW Longgang.
China Wanlin supplies the Aroma Humidifier with Flame Effect category as a direct manufacturer, not as a trading intermediary. The unit described below is one configuration out of 24 combinations (8 chassis x 3 SKU builds) that share a common misting family, a common oil path and a common documentation set, so a distributor can build a coherent shelf from one source rather than stitching together unrelated suppliers. Every unit referenced on this page corresponds to a specific bill of materials held on file, so the figures below can be reproduced or independently verified at sample stage.
The scent path is the part that separates this range from a humidifier with a few drops poured into the tank. The oil sits in its own tray or pad above the water line, on seals rated for citrus and resin blends, so the disc, the tank and the gasket never contact the oil. That is what keeps a scented unit serviceable for years rather than seasons, and it is the first thing we ask a buyer to check on a competitor sample.

Why Buyers Are Sourcing This Category Now
Three things move this category in Israel: heated or cooled air that dries a room faster than people expect, a home fragrance habit that has moved from candles to appliances, and a cleaning task that decides whether the product is still in use by March. Market entry cost keeps falling because small-batch first orders are viable: a distributor can test a range without committing to full container quantities on unproven models.
Returns in the Aroma Humidifier with Flame Effect category cluster around three causes: mineral dust on hard water, a scent that is stronger than the room wants, and a tray that cannot be cleaned. All three are answered at quotation stage rather than after arrival. This is why the table above states figures by model rather than by marketing tier: a buyer comparing two SKUs needs the noise on the sleep step, the run time per fill and the oil handling side by side, because those three predict both satisfaction and return rates better than any other set.
Wanlin serves Israel through three programmes that suit different balance sheets. New partners start with sample evaluation then a mixed trial order. Established distributors move to scheduled container shipments with locked pricing windows. Brand owners run private-label programmes with their own artwork and manuals. In all three cases the factory documentation, including the certificates and oil declarations listed further down this page, references the specific model code on the order rather than a generic family certificate, which is the most common cause of customs delay in this category. The WL-AH07F (PLUS) packs 24 units to a carton, carries 18 months of warranty cover and a 25-35-day stated lead time, and draws 3.1 W on the high step.
Engineering Notes - Misting, Oil Path and Water Quality
Three numbers decide whether this category works in a room, and only one of them appears on most specification sheets. The first is millilitres per hour, quoted for both steps so a buyer can divide it into the tank capacity and know how long a fill lasts before ordering a single unit. The second is hours per fill, which is the number that decides whether a unit needs filling every night or every second night - and therefore whether it survives its first season in a household.
The third is the oil side, and it is the one nobody quotes. Scent is consumed at a rate, not by a setting, and across this range that rate sits between roughly 0.22 and 0.35 mL per hour depending on the step and the disc. Divide the tray capacity by that rate and a buyer knows how many nights a fill of oil lasts, which is the figure that decides whether the product is a pleasure or a chore. Ours is published per model and per step.
Every production batch is sampled for four things before release: mist output against the declared figure by weighed run, the decibel reading at one metre on both steps, oil tray seal integrity after a 72 hour soak in a citrus blend, and dry-run shut-off function on an empty tank. For this configuration that means 27.6 mL per hour at 22.1 dB, holding 15.2 hours per fill and 14.3 hours of scent across a 21 sq m (223 sq ft) room.
Featured Deployment and Field Case Records
Three deployment records from the Aroma Humidifier with Flame Effect programme, each with the conditions that shaped it. Site detail is kept because it is the part that transfers: the water, the ceiling, the rota and the complaint are what decide whether a unit stays in service, and none of them appear on a specification sheet.
Case Study 1: Nairobi, Kenya
Deployment: A four-bedroom house in a gated compound, highland climate, dry season from June
Timing: Two dry seasons from June 2024
Nairobi's dry season is mild by any standard, and a buyer there does not need a large tank - what they need is a unit that runs quietly through the night on a small tank, because the water supply is intermittent and a large tank is a burden to fill. A 400 mL chassis with a night schedule is what went in, and the repeat order eighteen months later was for the same model in three more houses in the compound.
Case Study 2: Lucerne, Switzerland
Deployment: A lakeside hotel with 48 rooms, closed for six weeks each November for maintenance
Timing: Two seasons from May 2025
What decided this order was the shutdown. A programme that needs to be drained, dried and stored for six weeks and then set up again by a caretaker is a programme that gets abandoned in the second winter, so the specification included a written storage routine and a dry-out before the closure. It sounds trivial; it is the difference between a hotel reordering in year three and one that quietly stops. The hotel reordered in October 2026 with the same model code.
Case Study 3: Kowloon, Hong Kong, China
Deployment: A 280 sq ft flat on the 19th floor of a 1960s block, air conditioning for eight months of the year
Timing: One year from July 2025
Space is the whole specification in a flat this size: the unit had to fit on a bedside shelf next to a phone charger and be filled at a bathroom sink, not carried to a kitchen. A 250 mL chassis with a screw base went in, and the buyer's second order six months later was for four friends in the same block. The pattern in dense cities is that the form factor decides the sale and the capacity decides whether the customer comes back.
The pattern across all three is that the deciding factor was never peak output. It was whether the tank lasted a full shift, whether the oil could be refilled inside the round, and whether anyone complained about the smell or the dust. Those are the questions we ask before quoting. The WL-AH07F (PLUS) packs 24 units to a carton, carries 18 months of warranty cover and a 25-35-day stated lead time, and draws 3.1 W on the high step.
Application Scenarios Across Bedrooms, Offices and Hospitality
Four placement patterns cover most of the enquiries we see for this category. The useful observation is that each one is answered by configuration and placement rather than by buying a larger unit, which is the default reflex and usually the wrong one.
| Scenario | Room or site | What the site needs | What the unit does |
| SC03-WORKDESK | A single workstation with a laptop, a phone and a shared air supply | Moisture at the desk, and no smell a neighbour can object to | A compact chassis on the low step, placed upwind of the face rather than beside the keyboard, with the scent step left off in shared space. |
| SC09-HALL | Open-plan lobbies with a ceiling well above a residential one | Output sized against volume, with a target rather than a step | A large-tank chassis holds a measured target and stops when the room arrives, which is the only way a tall space is controlled rather than merely filled. |
| SC05-TREATMENT | Rooms booked back to back, where the scent has to leave before the next client | A scent that clears between appointments rather than building up | Scent and mist run on separate timers, so the room can be scented for a session and cleared with plain mist before the next client arrives. |
| SC01-BEDTIME | Master bedrooms where the scent is part of the wind-down routine | A scent that fades before the sleeper notices it, and a tank that lasts the night | A scheduled step-down holds output low overnight, the light goes fully dark, and the tray runs out of oil around the time the sleeper does. |
Two of these four are decided before the unit is switched on: whether the tank lasts the interval the site can actually service, and whether the scent level is one the room will accept. For this configuration that means 27.6 mL per hour at 22.1 dB, holding 15.2 hours per fill and 14.3 hours of scent across a 21 sq m (223 sq ft) room.
What a Factory-Direct Programme Changes for the Buyer
Three costs dominate ownership of this product and only one of them is on the invoice. The first is the appliance. The second is the consumable - cartridges, pads, replacement discs and, on many programmes, the oil itself - which is where the repeat revenue sits for every distributor we work with and which should be planned as a line item rather than bought occasionally. The third is staff time, because a tank that cannot be cleaned quickly is a tank that does not get cleaned.
A factory programme attacks all three. Consumables ship in the same container as the appliances, which is the cheapest way to buy them. Cleaning intervals are published rather than left to guesswork, and the tank geometry is chosen so the published interval is actually achievable by one person on a round.
What we do not offer is the lowest unit price in the market. A cheaper unit in this category usually buys a narrower tank neck, a disc of unspecified origin, seals that swell on contact with citrus oil and no spares path, and every one of those shows up later as a cost somewhere else. For this configuration that means 27.6 mL per hour at 22.1 dB, holding 15.2 hours per fill and 14.3 hours of scent across a 21 sq m (223 sq ft) room.
Certification, Oil Documentation and Market Access
Compliance in this category splits into three burdens that buyers often treat as one. The first is electrical and appliance safety: the CE technical file, an EMC test report and the IEC 60335-1 household appliance safety report, which is the set that gets a unit onto a shelf in Europe. The second applies only where a cell is fitted: a UN38.3 test report with an IEC 62133 cell report and an MSDS, which is the set that gets a unit onto a vessel.
The third is the oil, and it is the one that catches importers out. Where we ship oil with the unit we provide an IFRA-aligned statement of conformity, an allergen declaration listing the 26 declarable substances where they are present, an MSDS per blend and a flash point figure. That last number decides how the consignment is classified for transport: a blend below 60 C ships as a UN1266 Class 3 flammable liquid with the corresponding documentation and packaging, and a buyer who discovers this at the booking desk discovers it too late.
RoHS and REACH declarations cover the appliance materials, and because the oil contacts specific parts we also issue a material declaration for the tray, the seal and the pad rather than for the unit as a whole. Where a market needs a local approval, we issue against PSE, KC or RCM at the same time as the CE work rather than after it, because the test evidence largely overlaps. On the WL-AH07F (PLUS) the figures worth carrying into the next order are the 420 mL tank, the 14.3 hours of scent per oil fill, and the 22.1 dB reading on the sleep step.
Unit Economics, Consumables and Order Sizing
Three numbers decide whether this line works for a distributor, and the first one is not the unit price. Freight is the variable most buyers undercount: at 0.131 cubic metres per master carton of 24 units, a 20 ft container takes about 162 cartons, or roughly 3,888 units, and a 40 ft container about 357 cartons, or roughly 8,568 units. Those are volume figures before palletisation and loading losses, so a buyer should treat them as an upper bound.
The second number is the consumable. A misting disc is a wearing part with a service life measured in months of continuous use rather than years, and hard water shortens it considerably. Pads and cartridges sit on top of that, and where the programme ships oil, the oil is the fastest-moving line of the three. We suggest one spare disc per twenty units, one cartridge per unit where the water is hard, and a pad set per unit per year, and all of them ride in the same container as the appliances.
The third is the cost of a return. In this category returns split roughly evenly between mineral dust and a scent the room did not want, and both are prevented at specification stage rather than by a better returns process. For this configuration that means 27.6 mL per hour at 22.1 dB, holding 15.2 hours per fill and 14.3 hours of scent across a 21 sq m (223 sq ft) room.
Buyer Questions Answered
What order size does Wanlin accept for a first aroma humidifier shipment?
200 units per SKU on standard builds, 300 where a custom colour or private-label packaging is involved, and several models may share one container provided each SKU clears its own minimum. For a buyer testing the category for the first time, a mixed container is the lower-risk route and is the one we recommend over a single-SKU container on an unproven model.
Is the scent too strong for a bedroom, and can it be switched off?
Scent is the most common cause of a unit being unplugged, so this range treats it as a setting rather than a feature. WL-AH07F offers three intensity steps, and the light can run with the scent switched off, and the tray can be left empty entirely, which is what most nurseries, shared offices and clinical rooms specify. A bedroom on the low step sits well under anything a neighbour would notice, and the light, flame, volcano and rain-cloud light programmes plus seven fixed colours, switches fully off.
Will an ultrasonic aroma humidifier put mineral dust on dark furniture?
On hard water, yes, unless the build deals with it. The disc atomises the water and everything dissolved in it, and the minerals settle as a white film. For WL-AH07F-PLUS the answer built into the specification is cartridge optional, drops into the filler neck. Where a buyer wants the question removed entirely, running on distilled water removes it without any cartridge.
What documentation comes with an aroma humidifier shipment for customs?
CE technical file, RoHS and REACH declarations, an EMC report and the IEC 60335-1 appliance safety report as standard, plus UN38.3, IEC 62133 and MSDS on any build carrying a cell, and FCC for the digitally controlled models going to North America. Where oil ships with the unit: an IFRA statement of conformity, an allergen declaration, an MSDS per blend and the flash point figure that decides transport classification. Every document names WL-AH07F rather than a family, which is what a customs officer checks.
Is private label available across the aroma humidifier range?
Across the whole range, including housing colour, logo, retail artwork, manual language, the accessory kit and the gift-box configuration. Most of it works inside existing tooling, so it does not add engineering time. What it does add is a decision about consumables, and we raise that early because the cartridge and pad choices affect the return rate more than any artwork decision does.
What is the cleaning routine, and how much staff time does it take?
Five to seven days in continuous use, or three to four where a scent runs daily, with a dry-out before any period of storage. The routine takes under two minutes on this chassis because the tank opening is wide enough for a hand and a brush, which is deliberate. A narrow-neck tank takes longer, gets cleaned less often, and eventually gets replaced - which is the real cost of a cheap moulding. Where a Israel supply is hard the interval shortens rather than lengthens, and we would rather say that at quotation stage than have a buyer discover it from a complaint.
What happens if a unit fails inside the warranty period?
18 months on WL-AH07F against manufacturing defect. In practice most failures outside the warranty period are a worn disc, a scaled cartridge or a seal that has met the wrong oil rather than a faulty appliance, which is why we stock all three as separate lines and ship them with the units. A distributor who can supply the part keeps the customer.
What is the timeline from sample approval to a shipped container?
From approved sample to a shipped container, 25-35 days for first production plus the freight booking step, which is longer on battery builds because of the cell documentation and on any order carrying oil because of the transport classification. Sampling itself is 5 to 7 working days on an existing specification. We put the production figure on the proforma invoice so it is a commitment rather than an estimate.
Who This Programme Suits
The programme suits any buyer who has to answer for the product after it is sold, which in practice means everyone except the pure spot trader. A distributor carrying a range needs to know which chassis to put in front of which customer, and the answer is usually decided by water hardness, by who refills the tank, and by how much scent the room will accept.
Hospitality buyers need a fill interval that fits a housekeeping round. Clinical and childcare buyers need a material declaration for every oil contact part and a light that can be turned fully off. Retail and fragrance buyers need a tray they can demonstrate in front of a customer in under a minute. Facilities buyers need one unit per occupied room rather than one per floor, and they need the reasoning written down so it survives staff turnover.
What all of them have in common is that they are specifying against a room and a routine rather than against a specification sheet, which is why we ask about the site before we quote the unit. For this configuration that means 27.6 mL per hour at 22.1 dB, holding 15.2 hours per fill and 14.3 hours of scent across a 21 sq m (223 sq ft) room.
How a First Order Is Structured
First orders go wrong in two predictable places, and both are administrative. The first is documentation raised against the wrong model code, which stops a container at the destination for a reason that has nothing to do with the product. The second is a packing list decided after production begins, which forces either a second shipment or a compromise on the spares - and, in this category, a compromise on the oil.
The sequence that avoids both is short. Agree the specification, the destination list and the oil list; evaluate a sample on that specification; confirm the packing list including consumables; then release production against a stated lead time written on the proforma invoice.
For a buyer new to the category we also suggest a mixed container across two or three SKUs rather than a single-SKU container, because the sell-through data from one mixed shipment is worth more than any forecast either side can produce in advance. For this configuration that means 27.6 mL per hour at 22.1 dB, holding 15.2 hours per fill and 14.3 hours of scent across a 21 sq m (223 sq ft) room.
Next Step for Import Buyers
Two things decide whether this product works, and neither is on the box: whether the tank lasts the interval the site can actually service, and whether the scent level is one the room will accept. Get those two right and the rest of the specification rarely matters.
Everything else on this page exists to make those two decisions possible before money moves - the figures by model rather than by marketing tier, the measurement conditions stated next to the decibel, the oil rate stated per hour, and the honest statement of where the answer depends on the room.
Enquiries are welcome from anyone supplying this category at volume, whether as an importer, a distributor, a brand owner, a fragrance or gift company, a facilities or hospitality group, or a cross-border seller. Samples and the full documentation set are available on request. The WL-AH07F (PLUS) packs 24 units to a carton, carries 18 months of warranty cover and a 25-35-day stated lead time, and draws 3.1 W on the high step.
