    Before you buy an air humidifier

    Before you get all left-click-happy and press “Add to cart”, you should know that there are a few things you need to take into consideration first.

    From what we’ve learned, the three most important factors you need to look at are the following:

    • The size of the unit
    • The features offered
    • Your health

    When it comes to size and the rest of the features, we’ll cover that in a bit, so, let’s talk health.

    If you’re someone who suffers from allergies or asthma, you’ll want to be careful when using an air humidifier. You wouldn’t want to get rid of dust mites, but still suffer from a runny nose.

    You see, if don’t take proper care of it, some of these are known to release what’s called “white dust”. This white dust is actually minerals that come from the water used in the humidifier.

    Now, for most people, this won’t be an issue. But, if you’re allergic to dust or have asthma, this could potentially trigger an attack.

    What to look for when buying a humidifier

    As we’ve just mentioned, a big part of the purchase will be the features offered by the humidifier. So, let’s take a more detailed look at each one, shall we?

    Ultrasonic vs evaporative

    The two most common types of air humidifiers are ultrasonic and evaporative. So, what’s the difference between the two?

    Ultrasonic humidifiers use high-frequency vibrations to create a mist. This mist is then released into the air, where it does its job of adding moisture to the room.
    On the other hand, an evaporative humidifier works by drawing in dry air and passing it through a filter and a fan. The filter is soaked in water, which then evaporates and humidifies the air.
    Even though you might think the latter is more prone to mould, with wet filters and all that, it’s actually the opposite.

    Evaporative ones require frequent filter changes, which is why they aren’t prone to mould. However, neither are ultrasonic ones, if you make it a habit to give them a thorough scrub once a month.

    Cool mist vs warm mist

    When it comes to mist, you also have the choice of cool or warm. So, again, what’s the difference? Which should you go for – cool or warm mist humidifiers?

    Well, as you might’ve guessed, cool mist humidifiers release cool mist into the air, while warm mist humidifiers release warm mist. So, that’s one thing to keep in mind.
    The main difference between the two is in the internal workings of the humidifier. Cool mist humidifiers use a fan to blow air over a wick, which then evaporates the water and releases it into the air.

    On the other hand, a warm mist humidifier has a heating element that boils the water and releases steam into the air. Some may claim this makes the water vapor “healthier” as heat kills the bacteria, but we really wouldn’t worry about that one a lot.

    Also, the latter is a bit quieter, therefore, you might want one of these in your bedroom if you’re particularly sensitive to sound.

    Size & dimensions

    The next thing you’ll want to take into consideration is the size of the unit. You see, some humidifiers are meant for small rooms, while others are meant for larger rooms or even an entire house. To figure out what size you need, you’ll first need to know the square footage of the room you want to use it in. Once you have that number, you can consult a humidifier buying guide, which will tell you what size you need.

    As a general rule of thumb, you’ll want a humidifier that can cover at least 250 square feet. But, if you have a particularly large room, you might want to get one that can cover up to 600 or even 1000 square feet, at which point you’d probably go with a console humidifier with a sizeable water tank.

    Operating time

    Operating time, run time, whatever you want to call it, this is the amount of time the humidifier can run before it needs to be refilled. Now, this will depend on the size of the water tank. The larger the tank, the longer it will be able to run.

    Some models can run for up to 60 hours on a single fill, while others will only last for around 12.
    If you have a large room or want to use the humidifier for an extended period of time, you’ll want to go with one that has a larger water tank.

    On the other hand, if you only need it for a couple of hours at a time, you can get away with one that has a smaller tank, which is mostly what you’d use in a compact bedroom.

    Tank design

    The design of the water tank is also something you’ll want to take into consideration. You see, some models have a removable tank, while others have a fixed tank. The main advantage of a removable tank is that it’s easier to refill. You can just take it to the sink, fill it up, and put it back. Although, we would suggest using distilled water if you have the means for it.
    On the other hand, fixed tanks are a bit more difficult to refill, as you have to carefully pour the water into them without spilling.

    Another thing to keep in mind is that some models have a wide opening, while others have a smaller opening. The advantage of a wide opening is that it’s easier to clean, as you can reach inside with a cloth and give it a good wipe down, but that’s just nitpicking at this point.

    Convenient maintenance

    Ease of use and even easier maintenance, that’s what you want in a humidifier. We’re not saying that all humidifiers are difficult to maintain, but some definitely require more work than others. The bottom line is that you want a humidifier that’s easy to clean and doesn’t require too much work to keep it running smoothly. What would count as convenient maintenance? A removable tank, for example.

    Tips for buying and using a humidifier

    Whether you’re looking for a particular ultrasonic cool mist humidifier or you’re just browsing and waiting for something to catch your eye – we’ve got you covered.

    In this section, we’re going to tee up a few of the most important buying tips to keep in mind when shopping for an air humidifier.

    • Read the reviews – When it comes to making a purchase, reading reviews is always a good idea. It helps to get an idea of what other people are saying about a product before you buy it.
    • Buy from reputable brands – Not all humidifiers are created equal. There are some brands that are known for their quality products and others that, well, aren’t so much.
    • Know that price isn’t the be-all and end-all – Just because a humidifier is cheaper doesn’t mean it’s going to be a bad purchase. There are plenty of affordable options out there that are still of great quality.

    And, once you get your hands on the best humidifier, do the following:

    • Be sure to read the instructions manual – Every humidifier is different and it’s important to know how to use yours properly, therefore, read the manual.
    • Clean the humidifier regularly to prevent bacteria build-up – No one wants to breathe in bacteria-filled mist, so be sure to clean your humidifier on a regular basis.
    • Refill the water tank as needed to ensure optimal performance – Don’t let the water level get too low, as this can cause the humidifier to work less effectively, or potentially even break.

    The advantages of owning a humidifier

    It’s one thing to get your hands on a great new product, but it’s another to fully understand what that product is capable of. Therefore, we’re going to give you a quick rundown of all the advantages that come with owning an air humidifier.

    • Prevents respiratory problems – By adding moisture to the air, humidifiers can help prevent respiratory problems, such as bronchitis, sinusitis, and nosebleeds.
    • Eases congestion – If you suffer from allergies or a cold, a humidifier can help ease congestion by moistening the air and thinning out mucus.
    • Reduces snoring – If you or your partner snores, a humidifier can help by moistening the air and making it easier to breathe. This, in turn, will reduce snoring and help both of you sleep better.
    • Soothes dry skin and throats – The dry air that comes with winter can cause all sorts of problems, like dry skin and sore throats. By using a humidifier, you can add moisture to the air and help alleviate these problems.
    • Eases allergies and asthma symptoms – If you suffer from allergies or asthma, a humidifier can help by adding moisture to the air reducing symptoms of asthma or allergies. Just make sure you properly clean it, otherwise, you can end up on the other side of this coin.
    • Promotes better sleep – By making it easier to breathe and reducing snoring, humidifiers can help you sleep better. In turn, this will lead to more energy during the day and better overall health.

    There you go. If those aren’t enough for you, then we don’t know what is. The way we see it, these benefits are more than enough.

    FAQs about these best humidifier uk picks

    In the end, we thought we’d answer some of the most frequently asked questions about air humidifiers. Sounds good? Alright.

    You clean the humidifier by emptying the water tank and wiping down the interior with a clean, damp cloth. You should also descale the humidifier on a regular basis to prevent mineral buildup.

    You can, but we would advise against it. Distilled water is a much better option.

    Warm or cool mist, huh? Well, there really isn't a definitive answer to this question. It depends on your personal preferences.
    Some people find that cool mist humidifiers are more refreshing, while others find warm mist humidifiers to be more soothing. Ultimately, it's up to you to decide which one you prefer.

    Absolutely. Humidifiers can help to soothe sinus pain by adding moisture to the air and thinning out mucus.

    Not at all. In fact, many parents use humidifiers to help relieve their baby's congestion. However, we'd recommend sticking to the cool mist assortment.

    Yes, they do. As long as you keep them clean and free of mould and mineral buildup, most humidifiers can help to relieve the symptoms of asthma, congestion and allergies.
