I received this humidifier as a gift and have been really impressed with it. It’s easy to use and does a great job of adding moisture to the air, especially during dry nights.

Breville humidifier review
Does the job as expected. It is super easy to use and the buttons are very intuitive. The plastic lid at the top could be a little more secure as it seems to come off easily, but if you don't move the unit around much it's not an issue

Good humidifier
Overall I am quite satisfied with this. It does the job as expected. The water tank feels a little small. A larger one would reduce the number of times I have to refill

Good product with many features
This product is packed with features, like baby mode and a sleep timer. It’s also small and sleek. And the best part? I don’t have to refill the water tank often because it has a huge capacity. Overall, it’s a great product with many features. I highly recommend it!

At a glance
The Breville The Smart Mist Humidifier is a versatile humidifier for bedrooms, nurseries and medium-sized living areas up to 40 m2. Its strengths are the 5 L tank, cool or warm mist options, seven mist levels and automatic Sensair adjustment for easier day-to-day use. A fair limitation is that it is focused on humidity control rather than premium smart-connect or specialist air-purifying features.

Where it works best

- Everyday home users
Things to consider
It offers flexible mist control and automatic humidity adjustment, but it does not stand out as a premium smart-home or specialist purification model based on the provided specifications.
Room size suitability
Up to 40 m2 - a good fit for bedrooms, nurseries and medium-sized living areas
Allergy relief score
7/10 - added moisture and a water purifier cartridge may help improve comfort in dry rooms, but it is not a dedicated air purifier
Ease of use rating
8/10 - seven mist levels, pre-set modes and automatic Sensair adjustment make everyday operation straightforward
Aromatherapy compatibility
Not specified for essential oils; best used as a humidifier unless the product manual states otherwise
Noise level vs category
Average to quiet for category - suitable for bedrooms and nurseries based on intended room use
Key benefits
- Cool or Warm Mist: Lets you choose the mist type that feels more comfortable across seasons and room conditions.
- 40 m2 Room Coverage: Well suited to bedrooms, nurseries and medium-sized living spaces without needing a larger console unit.
- 5 L Water Tank: Reduces how often you need to refill compared with smaller-capacity humidifiers.
- Seven Mist Levels: Gives you more precise control over humidity output for sleep, daytime use or changing weather.
- Pre-set Modes: Makes it easier to match operation to different routines or comfort preferences.
- Sensair System: Monitors conditions and adjusts mist output automatically to help maintain comfortable humidity with less manual tweaking.
- Water Purifier Cartridge: Helps keep the mist cleaner for everyday home use.
- 260 mL/h Evaporation Rate: Delivers a measurable moisture output suited to regular use in rooms up to 40 m2.
Q: What room size suits the Breville Smart Mist Humidifier best?
A: Breville The Smart Mist Humidifier is designed for rooms up to 40m2. That suits a bedroom, nursery or medium living area, but a larger open-plan space can feel less even because the mist has more air volume to cover.
Q: How often will the water tank need refilling?
A: Breville The Smart Mist Humidifier has a 5 litre tank, so it is built to go longer between refills than compact bedside units. Refill frequency still changes with the mist level, room conditions and whether you run cool or warm mist.
Q: Does the Sensair system adjust humidity automatically or manually?
A: Yes. Breville The Smart Mist Humidifier uses the Sensair system to monitor room conditions and adjust mist output automatically. If you prefer direct control, it also gives you seven mist levels and pre-set modes.
Q: Can I add essential oils to this humidifier?
A: No. Breville The Smart Mist Humidifier is not described as an essential-oil diffuser, so oils should only be used if the instructions specifically allow them. Oils can leave residue in a water-only humidifier and may damage internal parts.
Q: Is warm mist better for a nursery or bedroom?
A: It depends on the room and routine. This model offers both cool and warm mist, so cool mist is the simpler everyday choice for a nursery, while warm mist can suit cooler weather if you want less of a cool feel near the unit.
Q: Will it fit on a bedside table or shelf?
A: Yes, in many cases. Breville The Smart Mist Humidifier measures 353mm high, 230mm wide and 184mm deep, so its footprint suits many bedside tables or shelves. It still needs a stable, flat surface with space for the mist outlet.
