On the downside, this model does not feature a built-in timer, although thanks to the mist flow adjustability you have a good degree of control over how much moisture is released.

The Aennon Cool Mist Humidifier is our best value choice thanks to its great design and generous 2.8-litre capacity.
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.

Combined with its seven colour changing night light, this humidifier is also perfect for creating a calm ambiance in which you can unwind and destress.

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’re looking for a low-cost air humidifier, check out our budget pick: the Tenswall Wood Grain Humidifier.

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, for the price, it is still an excellent value for money.

Unlike opaque models, this ensures that you can see right through and verify the cleanliness of the tank, while the opening makes thorough cleaning much easier.

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.

One small knock and water will go everywhere, which isn’t ideal if you have pets or kids.

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.
Humidifiers are simple and effective appliances that can really make a world of difference to the health and comfort of yourself and your family, especially if you suffer from allergies or have young children.
If you’re still unsure which model to choose, we think the best humidifier UK is our editor’s choice – the Pro Breeze Ultrasonic Humidifier.
With its generous capacity and extra-long runtime, this model is one of the easiest to clean. Its detachable, transparent reservoir ensures that you won’t experience any unhygienic build-up, while the integrated ceramic filter ensures that any water impurities are removed before vaporisation.
Furthermore, the fully adjustable mist control allows you to finely tune the amount of moisture released into your room for optimum humidity levels to suit your needs and surroundings.
And if all these features weren’t great enough, you can also use it as a night light or essential oil diffuser to create a freshly-scented home that promotes relaxation and wellbeing.
