If you are looking for an ultrasonic warm and cool mist humidifier, then take a look at this futuristic-looking Levoit LV600HH diffuser. Able to cover rooms up to 70m2, you can be sure that this humidifier will easily manage large, open-plan homes. Its whisper-quiet operation is perfect for overnight use and for light sleepers, too.
For rapid humidification, use the warm mist setting. This will also ensure that the water is heated to kill off any bacteria present. It’s ideal if you or anyone in your family is particularly susceptible to infection or illness.
Thanks to its dual 360-degree rotating nozzles, you can direct the mist away from your furnishings and walls. Additionally, this model has a large six-litre capacity and can generate an impressive maximum mist output of 500ml per hour – with up to 36-hours runtime!
Also, this ultrasonic humidifier has a smart auto mode for convenience. You can simply select your desired humidity level and leave the machine to regulate itself for optimum comfort. If you often struggle to unwind, the built-in essential oil aroma box helps to create the perfect environment for relaxation.
Complete with an LED display, remote control, and touch buttons – this unit is easy to use. However, the manual could do with an update. The screen can be turned off at night, too. But, the remote needs to be used within a few metres of the unit to work correctly. We also would have liked the tank to be a little less tricky to refill, though it becomes much easier with practice.
All in all, if you are looking for a smart humidifier that looks as good as it works, we think this model makes an excellent all-round choice.
With its whisper quiet-operation and generous 2.8-litre capacity, this Aennon Cool Mist Humidifier is an ideal model for creating a soothing environment. Certified to have passed the ETL Safety standards for children, this unit makes an excellent option for baby and kids room.
With a runtime of over 20 hours on its lowest setting, this humidifier is a great choice if you are looking for a model to leave switched on for long periods of time. This is especially valid as this unit does not feature a timer function. It does, however, have an auto shut-off, so you won’t have to worry about leaving it on in your absence and having water level running too low.
Other features include a whisper-quiet operation, making it suitable for use in any room of your house, as well as a built-in aroma diffuser for use with essential oils. Combined with its seven-colour changing night light, this humidifier is also perfect for creating a calm ambience in which you can unwind and destress.
On the downside, the provided instructions are not very clear. What’s more, as it’s difficult to get your hand right inside to the bottom of the tank, it can be a little tricky to clean it out thoroughly. However, on the whole, this is a good-sized humidifier that is suitable for the majority of homes where you need to keep the humidity level boosted over long periods.
If you are looking for a high capacity humidifier, then make sure you take a look at this model by PureMate.
Its stylish cube design features a generous 5-litre reservoir that can last for up to 20 hours of continuous use, saving you the inconvenience of frequent refillings. This makes this model a good choice if your home has large rooms with very low humidity levels. The second main advantage of this popular humidifier is that it can produce both warm and cool mist, making it a warm and cool mist humidifier in one, saving you space and money.
Featuring an essential oil tray, you can use the PureMate to diffuse aromatherapy oils to promote relaxation and well being. Therefore, if you are looking for a humidifier for your bedroom, this ultra-quiet model makes an excellent choice. It also features a Night mode, to ensure that it will not wake you or emit any light, ideal for your bedside cabinet. You can adjust the mist flow rate and this unit also has a long-life filter and air ioniser for healthier, cleaner air.
Unfortunately, this model does not feature a timer, so it is less suited to homes that only require a slight boost to their humidity levels. It is also fairly bulky and rather heavy when full, but that is to be expected with its extra-large capacity.
On the whole, this is a stylish, well-made humidifier that really stands out with its warm and cool mist settings and long-life filter. If you are looking for a discreet, high capacity model then we think this makes a great choice.
If dry air is ruining your sleep, then you should definitely consider purchasing this model by VicTsing, our best humidifier for bedroom pick.
While it only has a small 150ml water tank capacity, it is compact and whisper-quiet with an operating noise level of just 20 dB. This makes it a great addition to your bedside table where other larger, noisier units may disturb your sleep or take up too much space. Thanks to its subtle, calming mood light function, you can set it to one of 14 light modes to make your bedroom extra relaxing.
While this unit is perfect for beside your bed, it is not great for very dry homes or very large rooms as it will only run for a few hours. This unit’s main drawback is that the top does not fit securely to the base, so you have to be very careful where you place it. One small knock and water will go everywhere, which isn’t ideal if you have pets or kids. However, it does benefit from a built-in timer, auto shut-off, and oil diffusing functions, putting it on a par with many of the larger, more expensive models on the market.
Overall, if you are looking for the best humidifier for your bedroom to gently boost a low humidity level with whisper-quiet operation, we think this stylish wood grain effect model is the one to go for.
This ultrasonic humidifier by Asakuki can also be used as a soothing mood light and aromatherapy oil diffuser.
Thanks to its clever design, you can use the light setting independently of the mist settings, increasing this unit’s versatility. You can even adjust the brightness, as well as selecting a fixed light colour or opting for all seven colours to cycle for optimum ambience. With its 500 ml capacity, this air humidifier has a large enough tank to last you through the night and its waterless auto shut-off means you won’t have to worry about leaving it running. Although, if you’re a light sleeper, you may not want to have it right next to your bedside, as it tends to make a light trickling noise that may disturb your shut-eye.
Aside from its light and aromatherapy functions, one of this unit’s main highlights is its integrated timer. This is ideal if you want to improve your home’s humidity without risking excessive moisture, enabling you to set your humidifier to run for a set duration when you may not be around to turn it off. While it is easy to use once you have the hang of it, you may initially struggle due to the poor instructions and the top can be fiddly to remove when you need to refill.

This model can run continuously for up to 40 hours without needing to refill, or you can opt to set the timer for a certain duration as required. Should it run dry, it’ll automatically cut off. The four-layer filtration system ensures cleaner and healthier air, which is a welcome feature if you suffer from allergies.
Bear in mind that the filters in this model will need regular cleaning, once to twice per week. Also, the power cord is a little short, so you may have to compromise on placement. However, the main drawback of this particular unit is its relative humidity sensor that’s not as reliable as some more expensive models.
All in all, this ultrasonic humidifier is still a great choice for improving your home’s humidity levels, as well as promoting wellbeing and relaxation.

Humidifier Buying Guide
Which Humidifier is Best Warm or Cool?
While cool mist, ultrasonic humidifiers are the most common choice, both warm mist and cool mist models have their own set of advantages and disadvantages.
Both types will work wonders at reducing troublesome dry air by bringing moisture up to comfortable levels. Which one is best for you depends upon your preferences and where you are planning to use it.
To help you to decide which model is best for your home, here’s a summary of the main benefits of each type of humidifier.
Warm Mist Humidifiers
Warm mist humidifiers will boil the water and then disperse it as a fine warm mist. This has the added advantage of killing off any bacteria that could be present in the water. This feature makes them a little more hygienic than their cool mist counterparts, especially if you don’t sanitise yours as regularly as recommended.
While warm mist humidifiers are recommended for small spaces, they are generally less effective than cool mist ones in larger rooms. They also cost more to run and can be dangerous if you have pets or small children as they can cause burns if knocked or pulled down.
Cool Mist Humidifiers
Cool mist humidifiers release a steady stream of cool mist into the air, often by using ultrasound to ‘shake’ the water into smaller droplets. The mist created is room temperature, so while it isn’t warm, it’s also not a cold mist.
As ultrasonic humidifiers do not heat the water first, they are cheaper to run as they use less electricity. They are also recommended for use in homes with kids or pets as they do not present a risk of burns if they are accidentally knocked over. On the other hand, cool mist humidifiers can cool a room down slightly which may or may not be a desired additional effect.
If you are uncertain which type is best for your needs, you could opt for a model that has both cool and warm mist modes. These hybrid models enable you to select either mode to suit both the room and your individual needs. For example, many people find that running a cool mist humidifier in summer helps to cool down their rooms, while in the winter months, they prefer the soothing sensation of warm mist to ease stuffy noses.
Whichever type of humidifier you choose, both types will combat dry air and increase your humidity levels as effectively as the other. Therefore, your main considerations should relate to safety, room size and personal preference when making your choice.
Which Humidifier is Best for Winter?
When you’re choosing a humidifier to combat dry air in your home during winter, it really comes down to a matter of personal preference.
Having taken into account the benefits of both warm mist and cool mist models, during the winter, you may prefer to opt for a warm mist one. Warm mist humidifiers are slightly more hygienic as they boil the water first, thus killing any potential bacteria and mould. Also, as cool mist models are associated with refreshing, cool air, you may prefer the soothing sensation of warm mist during wintertime. However, with the heating on and your home’s air all dried out, a cool-mist model can also be equally desirable over the winter months.
When making up your mind, you should focus on the main advantages of each model and ensure that it has an adequate capacity for your home and anticipated usage. In short, both types are suitable for use in winter, so make your choice based upon your home and the features that will be most useful to you. If you’re planning to use your humidifier at night time, then opt for a whisper-quiet model or one that features a special “sleep” mode. For relaxing winter evenings, select a humidifier with an oil diffuser tray to create a cosy fragrance or choose one with a colour changing mood light for extra relaxation.
In general, cool mist, ultrasonic humidifiers are the most popular type thanks to their low cost, safety around toddlers and better suitability for larger rooms. If you are struggling to decide which type of humidifier to choose for winter and you’ve never tried one before, we recommend opting for one of the cool mist models from our humidifier review selection. All are reasonably priced and offer good value for money, as well as being perfectly suited to use in both winter and summer alike.
How to Humidify a Room for Babies
If you have a baby or are expecting, you’ve probably heard about the advantages of placing a humidifier in their room. With their delicate skin and tiny noses, humidifiers can help your baby to breathe and sleep better as well as preventing their skin from drying out. Eliminating dry air by increasing humidity levels in your child’s room can also help them to recover quicker from lingering colds while helping to keep future respiratory infections at bay.
In order to correctly humidify your baby’s room, you will first need to find a suitable place to locate your humidifier. Note that due to the increased risks associated with babies and toddlers, you should only use an ultrasonic cool mist humidifier in any child’s room. Not only will you need a stable, out of reach location, but it will also need to be close to a plug socket and in an area that allows the moist air to spread through the entire room. Do not localise the mist towards your baby or their bedding.
With your ultrasonic cool mist humidifier set up, you will need to fill it up with demineralised water. While you could use normal tap water, using demineralised water ensures that there is no chance of any minerals being dispersed into the air in water droplets which could then irritate your child’s skin or tiny nasal passages.
Always keep an eye on the humidity levels in your baby’s room and adjust your humidifier as necessary. An atmosphere that contains too much moisture is as bad, or even worse, as one that is too dry; so if you see any signs of damp you should take action immediately. Using a hygrometer is the best way to get an accurate humidity reading of your baby’s room.
It is generally advised to clean out your humidifier every week to stop a build-up of bacteria in the water tank. However, given the sensitivity of young children and babies, we recommend daily cleaning to ensure that your humidifier is 100% sanitised and free from germs.
Picking the best humidifier for your home can be tricky, especially if you have no experience with these kinds of appliances. If you’re still on the fence after reading our humidifier reviews, we recommend opting for our Editor’s Choice – the Levoit Humidifier LV600HH.
This device is packed with winning features. Not only does it have a generous six-litre capacity that can easily manage the largest of rooms, but it also has dual cool and warm mist. Plus, it’s equipped with 360-degree nozzles to ensure rapid and effective results.
Whisper-quiet and with an outstanding runtime of up to 36-hours, this model is perfect for use overnight. You can even use it as a baby humidifier. Moreover, the built-in essential oils tray allows you to create a beautifully relaxing atmosphere to unwind. And, the handy LED display can be switched off so as not to disturb your sleep.
Want to set-it and forget-it? The Levoit Humidifier LV600HH offers an impressive smart auto mode that does the hard work for you. Choose your preferred humidity level and get on with your day in comfort. If you feel like changing the settings, simply use the handy remote control to adjust the output.
