The Levoit humidifier is equipped with a Bluetooth and WiFi connection allowing you to easily control the settings from a Smart device. It is also voice control enabled, so you can connect it to your Alexa or Google Assistant for hands-free adjustments.
This humidifier has a top-fill design on its detachable 6-litre tank, making it easy to fill without accidental spills. Impressively, its large water tank can produce mist for up to 60 hours on the lowest of its three mist settings.
The Levoit humidifier also features a sleep mode with a dimmable night light that can be turned completely off if you prefer a more undisturbed sleep environment. A built-in pad for diffusing essential or fragrance oils allows you to add aromatherapy scents to your room as well.
Keep in mind that this humidifier could have a less accurate automatic humidity sensor so you may be better served by controlling it manually. It can also be a bit noisy and is not the easiest to clean.
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.
All in all, this five-in-one humidifier, oil diffuser, and mood light makes a great option if are looking to boost your relaxation and wellbeing as well as improving your home’s humidity levels.
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.

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 reliable ultrasonic humidifier, take a look at this premium model by Pro Breeze.

However, as you need to turn it upside down to fill, be prepared to experience some dripping water while filling and replacing it.
Aside from the lack of an in-built timer, this unit has all of the features that you would expect and need from a high-quality humidifier, including an essential oil tray, an auto shut-off function, and an optimised ion exchange filter. You may or may not find the light function useful; however, if you are looking for a humidifier for your bedroom, be aware that the light cannot be turned off and the glow may keep you awake at night.

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 of 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.

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-around choice.

With this humidifier, you also get a quiet sleep mode that turns off the screen, a timer, remote control, and automatic shutoff functions. A convenient carry handle and a diffuser compartment are also built into the machine.
Unfortunately, this option has a less effective aroma diffuser and has harder-to-clean crevices. Additionally, the humidity sensors may fluctuate somewhat, making them less reliable.
If you’re looking for an air humidifier, check out the Tenswall Wood Grain Humidifier.
Its 500 ml reservoir is a practical size, ensuring that you regularly change the water, without requiring you to refill too frequently. It also benefits from a choice of intermittent or continuous mist modes. This means that it can last much longer on one refill than other sized models while giving you a degree of control over the amount of mist released. Unfortunately, this model does not have fully variable mist control.
Other drawbacks include the fairly short cable length and that it can be a little noisy. However, it is still an excellent product. Complete with a seven colour LED light and oil diffusing capability, this humidifier also makes a soothing relaxation aid. We think its unique form and curved styling is sure to complement any room in your house.
Furthermore, the built-in timer is a great additional feature that is often lacking in other models, while the auto shut-off ensures that your humidifier won’t get damaged if it runs out of water.

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.

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 Top-Fill 6L.
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 offers utmost convenience with its WiFi connectivity and voice control features.
Whisper-quiet and with an outstanding runtime of up to 60 hours, this model is perfect for use overnight. Moreover, the built-in essential oils tray allows you to create a beautifully relaxing atmosphere to unwind. And, the night light can be switched off so as not to disturb your sleep.
Want to set it and forget it? The Levoit Top-Fill humidifier 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 free VeSync app on your phone to adjust the output. Or, you can try its voice control feature via Alexa and Google Assistant.
With all these features and an attractive, contemporary design, we’re sure you’ll agree that the Levoit Top-Fill is a worthy winner of the title ‘best humidifier in the UK’!
