Scent is dosed by volume, so the fixed figure is 187.5 m³. Floor area is that volume divided by your ceiling height - double the height and the area halves. Open-plan rooms, atriums and stairwells count as one connected volume. Spaces with heavy fresh-air exchange or doors held open need de-rating; air-change data is confirmed per project, never estimated.

How coverage is derived: cubic volume divided by a 3.75 m ceiling height. 187.5 m³ therefore equals about 50 m² / 538 ft² of floor area at 3.75 m, or about 60 m² / 646 ft² at a 3.1 m ceiling. Oil consumption carries a ±1x tolerance because viscosity varies by oil - thicker oils atomize more slowly, thinner oils faster.

One option to choose: the nozzle head

This page covers the Glass and aluminium alloy shell only. Every unit on it shares the same 75 x 75 x 127 mm / 2.95 x 2.95 x 5.00 in body, the same 187.5 m³ / 6 621 ft³ output and the same 2000 mAh battery. Two things move the unit price: the order quantity, which sets the tier, and the nozzle head, which adds +$0.32 on top of it. Colour is free.

The 24xx manual covers key functions, the three atomization gears, timer cycling, memory behaviour, charging states and safe-use limits. Buyers reselling into retail may reprint it under their own brand as part of a private-label order.

Safe use extract

  • Do not invert or tilt a filled unit - oil will drain into the pump and cause permanent damage.
  • Operate between 10 °C and 50 °C / 50 °F and 122 °F.
  • Switch the unit off before changing oil.
  • For long storage, remove the nozzle and store it separately from the body.
  • Do not modify or disassemble - this voids warranty.

Bottle change and level setup in 5 steps

Source: WD Aroma 24xx user manual. Total time about 2 minutes, no tools.

  1. Switch the unit off. Press and hold the power button for 2 seconds until every light is out. Never change oil while the pump is running.
  2. Release the bottle from the base. Push the bottle up from the bottom of the body to release the nozzle assembly, then unscrew the bottle from the nozzle.
  3. Fill and refit. Fill with neat essential oil, screw the bottle back onto the nozzle, then align the mark on the bottle holder with the mark on the body.
  4. Select the atomization level. Short-press the power key to cycle 10 s / 170 s, 30 s / 150 s and 90 s / 110 s. The chosen level is stored in memory.
  5. Set the timer. Press the timer key to cycle 1H, 2H, 3H and always-on. Display units offer 1H, 2H, 3H and 6H instead.

Volume logo work across the order, printed sleeves and custom retail boxes are quoted separately.

Buyer questions

How much oil should I budget per month?

Budget from the level and the hours you actually run it, not from the bottle. A 20 ml / 0.68 fl oz bottle lasts about 70 h at level 1, 20 h at level 2 and 7 h at level 3. On an everyday 3-4 h cycle, one bottle covers roughly three weeks at level 1 or about a week at level 3, so most homes use 1-2 bottles a month per regularly scented room. The specification sheet carries a ±1x tolerance because viscosity varies by oil. To rotate scents, use the smaller 5 ml / 0.17 fl oz and 10 ml / 0.34 fl oz bottles instead of leaving one bottle half-used.

What is the real difference between the high heads A / B / C?

They are 3 cosmetic top profiles on one common thread, all at the same +$0.32. The venturi sits inside the head itself, but it is the same venturi in all three, so mist output, particle size and oil draw are identical. The high heads stand about 1 cm / 0.4 in taller than the flat nozzle, which keeps atomised oil from condensing where it is visible. Buy a spare head to re-style existing stock instead of opening a second SKU.

Why is coverage given in cubic metres, and how does that map to floor area?

Scent fills a room in three dimensions, so coverage is rated as a volume: 187.5 m³ / 6 621 ft³, not a floor area. The floor area it covers is that volume divided by the ceiling height, so the same unit scents a larger footprint in a low room and a smaller one in a tall room. At a 2.4 m / 8 ft ceiling it is about 78 m² / 841 ft², at 2.7 m / 9 ft about 69 m² / 747 ft², and at 3.75 m / 12.3 ft about 50 m² / 538 ft². Treat open-plan rooms, stairwells and mezzanines as one connected volume.

Which oil bottles fit, and can I use my own retail bottles?

An empty 20 ml / 0.68 fl oz glass bottle ships fitted to the nozzle. Below that it takes the standard 5 ml / 0.17 fl oz, 10 ml / 0.34 fl oz and 15 ml / 0.51 fl oz bottles. They all share the common 18 mm screw thread (18 mm neck diameter): unscrew the retail cap and screw the bottle straight onto the nozzle, no adapter needed, or decant into the fitted bottle. Thick carrier oils, resins and anything with wax will clog the venturi - stick to neat essential oil and oily synthetics.

How does the running cost compare with an ultrasonic diffuser?

An ultrasonic unit dilutes oil into water, so the scent throw per millilitre of oil is far lower and the tank needs cleaning. This platform sprays neat oil at 0.2-0.74 ml/h and puts no water into the room, which is why it can sit next to laptops and mirrors. The trade is oil cost: you spend less on labour and refills of water, more on oil per hour at level 3.

What happens if it gets knocked over?

Past 45 degrees the tilt sensor cuts the pump, and misting resumes within about 1 second once the unit is back upright. Stand it up promptly: if it is left upside down, oil can run back into the air pump and corrode it, so righting it within 3-5 minutes prevents backflow. The bottle threads onto the nozzle rather than sitting loose, so an ordinary knock does not empty oil onto the carpet. Damage caused by prolonged inversion or spilled oil is user damage and is not covered by the 1-year warranty.

Can I get this model with a digital display?

A display build exists on this platform at +$0. It replaces the always-on timer slot with a 6H position and shows battery state on the panel. It is not a picker option on this page - put "display" on your RFQ and we build that version.

How is 187.5 m³ measured, and what do I buy if it is not enough?

It is the room’s cubic volume - length × width × ceiling height - not its floor area. Divide 187.5 m³ by your ceiling height for the footprint, as set out in the coverage question above. If your space is larger than that, do not run a portable unit on level 3 around the clock; step up to a mains-powered commercial unit that can be ducted into the HVAC system. Browse the commercial fragrance diffuser range for HVAC-tied installations.

What are the lead time, warranty and pump service life?

Small quantities ship from ready stock; production runs under 500 units take about 15 days and orders over 1 000 units about 30 days, confirmed on your quotation. The unit carries a 1-year warranty. This year we upgraded the whole platform from the 320 pump to the model 370 air pump - quieter, with higher airflow and finer atomisation - rated 2 000 hours on the specification sheet. Certification on file is CE, FCC and RoHS.
