How aroma diffusers compare with alternatives

An ultrasonic aroma diffuser atomises fragrance oil into a cool mist at 15 to 40 ml/h, which covers a 20 to 40 m² room. Compared with passive reed diffusers and heat-based burners, the output is adjustable and the unit can be timed.

Key differences

• The ultrasonic unit differs from a reed diffuser in that output is metered: 15 to 40 ml/h can be dialled down for a 20 m² bedroom or up for a 40 m² open-plan space, while a reed diffuser releases at a fixed rate that cannot be adjusted after opening.
• Compared with a candle burner, there is no open flame and no soot, and the unit shuts the mist off automatically when the 100 to 500 ml tank empties.
• Unlike passive products, the mist path is a wear item: the ultrasonic disc and the aroma pad are the two parts that set service life, which is why the pad is removable and oil is kept clear of the plate.

How this compares with the wider market

Buyers who compare quotations across this category will see other suppliers quoting a single minimum order of about 1,200 pieces that applies to the whole range rather than per model, and an industry average lead time of about 32 days that assumes stock is already on the floor. The ranges above are the ones this factory will put in a written quotation, so the two sets of figures are not measuring the same thing.

Where the alternatives still win

Passive alternatives still win where no power point exists and no maintenance visit is possible: a reed diffuser has no disc to scale and no tank to clean, and a candle delivers a stronger top note in the first ten minutes than any ultrasonic unit.

Bottom line: For rooms of 20 to 40 m² with a power outlet and a need for adjustable, timed output, the ultrasonic diffuser is the option that can be specified; for corridors and hotel rooms without power, a reed diffuser remains the practical choice.
