    Best gift

    Gift for my daughter. She said it was simple to set up and really helped clear her dry nose and throat symptoms which were caused by lack of humidity in her bedroom.

    Money well spent

    Bought it to pop in our sunroom for all the plants and to see if helped my cat's breathing. Used the app to set humidity then left it alone. Several weeks later both plants and cat are happier. Only had to refill reservoir twice. Well worth the cost of purchase

    Breville smart mist

    Really good humidifier. The app works well. It shows when the humidity levels become too high or low. Looks stylish with the different light colours. It's not a big unit which is good to save space.

At a glance

The Breville Smart Mist Glow Connect is a mid-range ultrasonic cool mist humidifier designed for small to large rooms up to 40 m². It suits households wanting quieter operation, app control and easy top-fill refills, plus an aromatherapy tray and mood light. Its main limitation is that it focuses on humidifying rather than offering premium air purification or larger-capacity coverage for very big spaces.

What it’s great for

  • Bedroom comfort
  • Nursery use
  • Home office humidification
  • Dry air relief
  • Connected home control

Where it works best

  • Bedroom
  • Nursery
  • Home office
  • Living room
  • Small to large indoor rooms up to 40 m²

Who it’s for

  • Families
  • Parents
  • Allergy-conscious households
  • Remote workers
  • Everyday home users

Things to consider

It is best for humidification rather than all-in-one air treatment, so shoppers wanting air purification, larger-than-40 m² coverage or a bigger water tank may prefer a more premium or specialist model.

Room size suitability

Up to 40 m²

Allergy relief score

8/10 - adds moisture to dry air and is certified and approved by Sensitive Choice and the National Asthma Council AU, though essential oils or additives are not included in that approval.

Ease of use rating

9/10 - top-fill design, adjustable mist levels, real-time humidity display and app control make it easy to live with.

Aromatherapy compatibility

Yes - includes an aromatherapy tray; use of essential oils, fragrances or additives is not Sensitive Choice approved.

Noise level vs category

8/10 - ultrasonic cool mist technology is quieter than traditional evaporators or steam vapourisers.

Key benefits

  • 4 L top-fill tank: Makes refilling simpler and less messy for everyday use.
  • Ultrasonic cool mist technology: Delivers a fine cool mist and is suitable for use around babies.
  • Seven adjustable mist levels: Lets you tailor moisture output to different rooms and comfort preferences.
  • Room coverage up to 40 m²: Suitable for bedrooms, home offices and many living spaces.
  • Real-time humidity indicator: Helps you see current humidity conditions at a glance.
  • App control: Lets you monitor and control the humidifier on the go.
  • SensAir System: Supports set-and-forget humidity management for easier day-to-day operation.
  • Mood light and aromatherapy tray: Adds ambience and allows optional fragrance use.

Q: Is the Breville Smart Mist Glow Connect suitable for use overnight in a bedroom or nursery?

A: Yes. It uses cool mist ultrasonic technology, which is quieter than steam-style units and avoids hot vapour, making it a practical option for bedrooms and around babies. Sleep mode also dims the control panel lights for less disturbance overnight.

Q: Can essential oils be used with the Breville Smart Mist Glow Connect?

A: Yes. This model includes a dedicated aromatherapy tray for essential oils, so oils are not added directly to the 4L water tank. Breville notes that use with oils, fragrances or additives is not covered by the Sensitive Choice approval for the humidifier.

Q: What can the Breville Home Connect app do on this humidifier?

A: The app lets you control the humidifier remotely and adjust humidity settings without being beside the unit. That is useful for changing mist output before bed or while away from the room, rather than relying only on the on-unit controls.

Q: How well does the Breville Smart Mist Glow Connect suit larger rooms or open-plan spaces?

A: It is designed for rooms up to 40m2, so it suits most bedrooms, living rooms and home offices within that size. In larger or very open areas, humidity may spread less evenly, so it works best when placed in the room where moisture is most needed.

Q: Why choose this Breville cool mist humidifier instead of a warm mist model?

A: A cool mist ultrasonic model is the better fit if lower operating noise and no hot steam matter most. This Breville is also suitable around babies, but it will not provide the heated vapour some buyers specifically want from a warm mist unit in winter.
