TL;DR - The Mistairhome WL-QH01S (PLUS) holds 420 mL and mists 46 mL per hour or 22.2 mL per hour, which is 9.1 hours and 18.9 hours per fill; it covers 12 sq m (130 sq ft) at a 2.6 m ceiling and measures 25.8 dB on the high step and 23.1 dB on the sleep step; it draws 2.6 W and runs from USB-C 5V/1A, runs from a laptop port or a phone charger; no internal cell on this build; it weighs 393 g and measures 10.4 x 10.4 x 18.6 cm, and ships documented to CE / RoHS / FCC standards for import into Czech Republic. MOQ is 200 units per SKU with a 25-35-day lead time, FOB Shenzhen or EXW Longgang.
China Wanlin supplies the Quiet Humidifier for Bedroom 26dB with Near Silent Operation 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 tank and seal line 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.

Shipping configuration: Plus build, + hard carry case + wick and cartridge starter set + gift box + funnel. Master carton holds 36 units. Stated lead time is 25-35 days from order confirmation and deposit. Misting discs, wicks and cartridges are repeat line items and are ordered separately from the appliance.
Three things move this category in Czech Republic: heated or cooled air that dries a room faster than people expect, buildings sealed tightly enough that nothing replaces the moisture, 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.
Distributors handling Quiet Humidifier for Bedroom 26dB with Near Silent Operation lines consistently find that the repeat revenue sits in the consumable, in cartridges and wicks and replacement discs, rather than in the appliance. 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 water handling side by side, because those three predict both satisfaction and return rates better than any other set.
Wanlin serves Czech Republic 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 battery files 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-QH01S (PLUS) packs 36 units to a carton, carries a 12 months warranty and a 25-35 days stated lead time, and draws 2.6 W on the high step.
Three engineering decisions separate this platform from the commodity end of the category. The first is how quiet is stated. A decibel figure without a distance, a room and a step is not a specification, so we publish the conditions next to the number: measured at one metre in a semi-anechoic corner, and quoted separately for the high step and the sleep step. The sleep-step figure is the one that belongs in a tender document, because it is the step an occupant actually leaves the unit on all night.
The second is where the noise comes from, because that decides how far it can be pushed down. Three sources remain once the fan is removed: the disc drive frequency, the turbulence at the outlet, and the structure-borne path into whatever the unit stands on. The first is handled by driving the disc below its resonant peak, the second by a low-turbulence outlet grille, and the third by a floating silicone isolator - which is why a unit reads measurably louder on a hollow bedside table than on a carpet, and why we quote the distance rather than letting a buyer assume.
The third is the trade that nobody states. Quieter costs output: a disc driven below resonance moves less water, and a restricted outlet moves less air. Rather than hide that, we publish both steps and let the buyer decide which one the room needs. On the WL-QH01S (PLUS) the figures worth carrying into the next order are the 420 mL tank, the 18.9 hours per fill on the low step, and the 23.1 dB reading on the sleep step.
Three deployment records from the Quiet Humidifier for Bedroom 26dB with Near Silent Operation 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.
Deployment: A care home with 96 rooms and a night shift of four staff
Timing: One year from June 2025
Night staff decide whether an appliance survives in a care home, because they are the ones who refill it. A unit that needs filling twice a night becomes a unit that is quietly left switched off. The large-tank chassis holds a night plus a working day on the low step, which is the whole reason the care home bought it, and the level window readable from standing height was mentioned twice in their feedback.
Deployment: An electronics retailer expanding its home-appliance aisle
Timing: One year from April 2025
Retail in Japan asks for documentation in Japanese and packaging that matches the shelf, so the first order was as much about print as about product. We supplied Japanese manuals and artwork with the PSE documentation issued against the model code on the order. The range was extended to a second chassis after the first quarter's sell-through.
Deployment: A regional distributor covering the Aegean coast
Timing: Two seasons from October 2024
The distributor sells into both pharmacy and hotel channels and needed two different documentation sets from the same shipment. Certificates issued per model code made that possible without a second test round, and the distributor now orders in a single annual container rather than seasonally.
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 unit could be cleaned inside the time a round allows, and whether anyone complained about the noise or the dust. Those are the questions we ask before quoting. The WL-QH01S (PLUS) packs 36 units to a carton, carries a 12 months warranty and a 25-35 days stated lead time, and draws 2.6 W on the high step.
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 |
| SC09-TANKRUN | Rooms with nobody responsible for refilling, and buildings on a weekly maintenance round | Refilling decides whether an appliance survives in a managed building more than performance does. | A large tank holding a night plus a working day on the low step, with a humidistat so the unit runs only when the room actually needs it. |
| SC10-LARGESPACE | Open-plan rooms, studios and lobbies with ceilings well above 2.6 m | A floor-area figure quietly assumes a standard ceiling, and a heritage or lobby space rarely has one. | Sizing against the room volume instead, and where the space opens to the outside, closed-loop control holding a target rather than a fixed mist step. |
| SC01-NURSERY | Night feeds and settled sleep in a room shared with an infant | Nothing should wake a sleeping infant, and no lamp should be on when the room is dark. | The sleep step holds output low all night while the chassis stays under the ambient level of a quiet bedroom, and the night light can be switched off entirely rather than merely dimmed. |
| SC02-BEDSIDE | A nightstand beside an adult bed in a heated room | A unit that has to be refilled at two in the morning stops being used inside a week. | A tank sized for a night plus part of the following day on the low step, with a level window that can be read from standing height before the light goes out. |
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 cleaning task fits the round. For this configuration that means 22.2 mL per hour at 23.1 dB, holding 18.9 hours per fill across a 12 sq m (130 sq ft) room.
The practical advantage of a factory programme is flexibility in how the first order is shaped, not the unit price. A mixed container across three SKUs lets a distributor test a range without committing to full container quantities on unproven models, which is the single biggest risk reduction available to a new importer and one that intermediaries rarely offer because it complicates their own purchasing.
The second advantage is lead-time honesty. A stated lead time of 15 to 35 days measured from order confirmation and deposit, written on the proforma invoice rather than left open, is worth more to a buyer planning a season than a faster number that slips. Battery shipments add a documentation step at booking, which we handle but which needs a few extra days on the freight side, and we say so before the order rather than after.
The third is continuity. Tooling, mouldings and the documentation set stay the same across seasons, so a distributor who lists a model code this year can relist it next year without a new test round. On the WL-QH01S (PLUS) the figures worth carrying into the next order are the 420 mL tank, the 18.9 hours per fill on the low step, and the 23.1 dB reading on the sleep step.
Four documentation errors account for most of the customs delay we are asked to fix, and all four are avoidable at quotation stage. The first is a certificate naming a family rather than the model code on the invoice. The second is a battery build shipped without UN38.3 and MSDS. The third is a manual in the wrong language for the destination. The fourth is a plug that does not match the destination.
None of those are engineering problems. They are paperwork problems, and they are the reason we ask three questions before quoting: which markets, which languages on the manual and the artwork, and whether any unit in the order carries a cell. Answering those three costs a buyer five minutes and removes the majority of the delay risk.
What we will not do is back-date a certificate or issue one against a model we did not build. A buyer who needs that is a buyer whose shipment will be stopped eventually, and the cost of the test is always smaller than the cost of the container sitting at the port. The WL-QH01S (PLUS) packs 36 units to a carton, carries a 12 months warranty and a 25-35 days stated lead time, and draws 2.6 W on the high step.
The economics of this line are an annuity, not a one-off sale, and buyers who plan it that way outperform the ones who do not. The appliance is the entry; the cartridge, the wick and the replacement disc are the repeat, and in the pharmacy and hospitality channels the consumable revenue overtakes the appliance revenue within the first year.
Freight is the part that needs doing carefully. At 0.092 cubic metres per carton of 36 units, a 40 ft container carries roughly 18,216 units by volume, and a 20 ft about 8,280. Those are upper bounds before pallet and loading losses, and the honest planning figure is a little below them.
What we suggest to a first-time buyer is deliberately unglamorous: a mixed trial order across two or three SKUs, spares at one disc per twenty units, a stated lead time of 25-35 days written on the proforma invoice, and a re-order point set by sell-through rather than by calendar. On the WL-QH01S (PLUS) the figures worth carrying into the next order are the 420 mL tank, the 18.9 hours per fill on the low step, and the 23.1 dB reading on the sleep step.
What is the minimum order quantity for a first quiet humidifier order?
MOQ is 200 units per SKU for standard builds and 300 units for custom colour or private-label packaging. Mixed-container orders combining several models are accepted as long as each individual SKU clears its own minimum. The specification table on this page shows the exact build we ship for WL-QH01S-PLUS.
How is the noise figure measured, and what does it mean in a bedroom?
We measure at one metre in a semi-anechoic corner and quote the step, so the two published figures for WL-QH01S are 25.8 dB on the high step and 23.1 dB on the sleep step. The sleep-step figure is the one to compare, because it is the step a bedroom unit is left on all night. A buyer can repeat the measurement in a quiet room with a phone application and will get within a decibel or two.
Does this humidifier leave white mineral dust on furniture?
It depends on the water and on the misting method, and it is the single largest cause of returns in this category. An ultrasonic disc throws everything dissolved in the water into the air, so on a hard supply it leaves a fine white mineral film on dark surfaces within days. Two answers exist: a demineralisation cartridge in the tank, which is a consumable with a real working life, or an evaporative build where the minerals stay in the wick. This unit is specified as cartridge optional, recommended wherever the supply is hard.
Which compliance files ship with a quiet humidifier order?
The standard file set is the CE technical file, RoHS and REACH declarations, an EMC test report, the IEC 60335-1 household appliance safety report, and for battery builds a UN38.3 test report with an IEC 62133 cell report and MSDS. For North America we add FCC documentation for the digitally controlled models. Certificates are issued against WL-QH01S, the model code on the order, rather than against a generic family.
Can we sell these under our own brand, with our own packaging?
Yes. Private label covers housing colour, logo placement, retail artwork, manual language and the accessory kit, and most of it sits inside existing tooling for this range, so customisation does not mean re-engineering. The decision we ask buyers to make early is which consumables travel with the appliance, because a unit sold without a cartridge into a hard-water market generates complaints that no artwork will fix.
How often does the unit need cleaning, and what does that involve?
Every five to seven days in continuous use, with a full dry-out if the unit will stand unused. That interval is why we specify a wide tank opening on this chassis: a tank a hand cannot reach into is a tank that never gets cleaned properly. Biofilm in standing water is the underlying reason, and it is not a defect, it is what water at room temperature does.
What warranty and spares support do you provide?
12 months against manufacturing defect on WL-QH01S. Misting discs, wicks, cartridges, seals and cells are stocked as separate line items and can ride in the same container as the units, which is the cheapest way to buy them. We suggest one spare disc per twenty units and one cartridge per unit where the water is hard.
How long does sampling and first production take?
Samples ship in 5 to 7 working days from an existing specification, or 15 to 20 days if a custom colour is required. First production runs in 25-35 days depending on SKU and quantity, measured from order confirmation and deposit, with the exact figure stated on the proforma invoice rather than left open. Battery shipments add a documentation step at booking.
Five kinds of partner buy this programme, and they want different things from it. Importers want container economics and documentation they can hand to a broker without rewriting. Regional distributors want a range coherent enough to explain on one page, and a spares line they can actually stock.
Brand owners want the artwork and the manuals right and the chassis underneath unchanged, which is the easiest request we handle because most of it sits inside existing tooling. Pharmacy and home-care groups want the consumable, because the repeat revenue is there rather than in the appliance. Cross-border sellers want prep: barcodes, multilingual manuals and packaging that survives a fulfilment centre.
Export traders sit across all five, and the thing they ask for most often is a specification sheet they can forward without editing, because their customer will ask about noise, run time and water before asking about price. On the WL-QH01S (PLUS) the figures worth carrying into the next order are the 420 mL tank, the 18.9 hours per fill on the low step, and the 23.1 dB reading on the sleep step.
The cleanest first orders we see share one habit: the buyer declares the destination list at quotation stage. Certificates, manuals and plugs all follow from it, and raising them once as a package costs far less than raising them market by market as each order lands.
After that the sequence is ordinary. Sample evaluation first, on the actual specification rather than a similar one, with the buyer measuring mist output by a weighed run, run time per fill at the low step, and noise at one metre in a quiet room. Then the proforma invoice, which carries the stated lead time and the packing list rather than leaving them open. Then production, then booking.
The one step buyers skip and regret is the spares decision. Adding a spare disc per twenty units and a cartridge per unit where the water is hard costs almost nothing on a first container and prevents the top-up shipment that otherwise arrives in the middle of the season. On the WL-QH01S (PLUS) the figures worth carrying into the next order are the 420 mL tank, the 18.9 hours per fill on the low step, and the 23.1 dB reading on the sleep step.
The right way to evaluate this unit is to order a sample on this specification and measure it: mist output by a weighed run, run time per fill at the low step, and noise at one metre in a quiet room on both steps. All three are reproducible, and a buyer who runs them will know more in an afternoon than any datasheet can convey.
We publish figures that can be checked, we state the ceiling height behind the coverage number, and we say plainly where the honest answer depends on the room or the water. That is a narrower claim than some competitors make, and it is the one we can stand behind at sample stage.
Export enquiries are welcome from distributors, brand owners, pharmacy and home-care groups, hospitality operators, cross-border sellers and export traders. Samples, specification sheets and the certification and battery files are available on request. For this configuration that means 22.2 mL per hour at 23.1 dB, holding 18.9 hours per fill across a 12 sq m (130 sq ft) room.
