    Golden Review Award: 4 From Our UsersWe have this in the bedroom, so very pleased with how quiet this is. You can switch the night light on and off, which is useful. You can vary the settings to get a little bit of humidity, or a lot. We find halfway works best, with a few drops of water-soluble eucalyptus.

    I’m a keen tropical plant collector and have purchased a few humidifiers over the years. Keeping my rooms at certain humidity levels is important for me and this humidifier is the best I’ve bought yet. Easy to clean and maintains the required humidity levels. Access control away from home is great with the app. Highly recommended

    Having looked around for different humidifiers this one seemed to offer a good overall balance of price whilst being able to automatically maintain a set level of humidity.

    The unit looks good and has good capacity – I have it set to 70% and it is able to go at least two days without needing a refill. The noise levels are really low which helps as I’m a fussy sleeper. The app is also really good, so I can set it up and let it run remotely.

    It is super easy to refill and the coloured LED’s are a nice touch but I don’t use them.

    Build quality seems pretty good and it doesn’t drip water around the unit. If you are after something you can set up and leave to it’s own devices whilst being quiet – I’d recommend this.

    This is a great unit that has really helped my breathing at night. I had been given an asthma pump to use during the night when waking up struggling with my breathing but I have been using this now for two months and have noticed a drastic improvement.

    The device is bigger than expected but it is slimline so I am sure a spot can be found for it in everyone’s bedroom. It is easy enough to get running and I have tried this with both just water and also essential oils too but personally they made my breathing go so I stick to the water alone now.

    This looks really modern and stylish and it has colourful lights too but I do find it quite bright at night so I have to turn it away from me.

    Although pricey I still say it is well worth it for the results it gives because a sleep filled night is priceless to me.

    4.0 out of 5 stars Helps with breathing at night but light is brigh

    Helped me with a eustachian tube dysfunction by keeping a humid environment. Love the fact I can control it from my phone and set both cold and warm air in one product. Fairly compact for what it is and easy to set up. Looks quite nice as well when lit up with pleasing leds.

    Price-wise is about right for the quality. Can’t fault it does the job fine.

    This is a quiet and adaptable humidifier. Via the app it is very easy to use and provides helpful feedback. Most if all it is efficient and impressively quiet. Easy to recommend.

    Golden Review Award: 2 From Our UsersThis is very nice indeed, both in function and in style !

    Really quick and easy to setup… just fill with water, hit the button and away you go.

    Good constant stream of vapour with a lot of adjustability, both from the unit itself, and also via the app.

    Bonus is that this can also be controlled via alexa too, which makes this stand out from most others out there.

    You can also add some essential oils via the small pop out drawer on the side (don’t add oils to the water tank !)

    Very modern looking, and provides a very calming ambient light in the room if you desire.

    Decent size, so it will run for hours on end with no issues, but also compact enough to fit easily in any room.

    Would definitely recommend for quality, functionality, and style.

    5.0 out of 5 stars Easy to fill, simple to use, and works very well

    Golden Review Award: 2 From Our UsersThis is an absolute game changer, over the small units this totally distroys them. The unit is a good size and holds suitable amounts of water to keep your environment at the correct humidity level all day long, i found the ability to add fragrance to the system magical giving a clear distinctive smell to my room at all times. The added smart functionality tops it all off. I cannot and do not want to switch this off.

    This works as well as I’d hoped it would.
    It’s fairly quiet which is unlike the previous humidifiers I have encountered.

    The lighting effect is excellent and the app control is smooth too. Quite user friendly.

    This has come to be very beneficial whilst working from home – so much better than being stuck in an air-conditioned office all day, which I’ve heard is not conducive to good health.

    This little thing is brilliant!

    Levoit it a name we know well in our household, we have a couple of air purifiers that work really well and now we have this quite substantial humidifier.

    One of our children suffers with asthma and the clinic advised getting her into swimming, when she was younger, since in addition to the physical benefits the humid environment of swimming pools would help to mitigate the effects of her asthma; we did and she has benefited in so many ways. At home and particularly in winter months she likes to use a humidifier for similar reasons. This one she is thrilled with since it will do cool & warm mist and she can control it with her phone (like everything else).

    This one from Levoit brings the humidifier into the 21st Century and it’s from a brand we trust given our use of the other air management things they make.

    As summer is approaching, my home fitness room is a bit stuffy and warm, especially on a sunny day. I cant open the window to get fresh air when I do yoga as the outside noise from cars and passerbys will distract me. The problem has been solved by Levoit Humidifier.
    This is the first warm & cool humidifier I have used. I switch it on 5 minutes before I start the yoga practice. When I stand on the yoga mat, I can feel the difference straightaway. The air is fresh and cool. I also add a few drops of essential oils for a nice scent. The humidifier is slim and compact. Refilling water and emptying the tank are easy as the water tank has a handle to carry and a large opening. The large capacity of the water tank can hold 4.5 litre water so you do not have to add water frequently. It automatically stops misting when the room reaches the desired humidity level.
    I also use it in the bedroom during sleep to keep our nasal passages moist when the heater is on. The misting sound is also very comforting.
    A must-have all year round.

    I was waking up with very dry eyes and skin so I started to look at what could be causing this so first I bought myself a good temperature and humidity meter and my humidity was very low so looked at ways to resolve this and come across this I have been using for a couple of weeks and I can feel the difference in my eyes and skin I like that you can control it for the app and set the levels you want the humidity to be
    When i first started using it I had turned off the nightlights but the display was very bright but then I found that you can turn it off in the app I am a light sleeper and thought that it would keep me awake but it is so quiet you do get the occasional gargling sound
    The one thing my wife does not like is it is very big and takes up a lot of space and takes a bit of maintenance having to clean it out every day

    You can feel the difference immediately

    This humidifier comes in a retail cardboard box and inside you’ll find the humidifier, 3x filters, cleaning brush, quick start guide, and a user manual.

    The humidifier feels well built with a good solid construction. It is comprised of two main parts which is the base and the water tank. The water tank has a carry handle and can be lifted off the base and is easy to refill. The tank has a wood effect lid which is actually plastic, but the wood grain effect is really effective, and you wouldn’t know it’s plastic just from looking at it. There is a gloss black panel on the front which has the screen behind which shows the current humidity level. There are also some touch sensitive buttons below this which just require a light touch for the button to activate.

    In use, it is quite simple to use. You remove the lid off the top of the tank and lift off the tank with the fold away handle. Fill the tank and place it back into the base. When you’ve filled the tank, no water comes out of it and is all contained within the tank. As soon as you place it back onto the base, you can hear water trickling out from the tank to fill the base up. You then touch the power button on the front and the unit turns on. When the water is cold, there isn’t a lot of mist when you first turn it on. It takes 2-3 minutes for the mist to really kick up and does give out a decent amount of mist. There are two vents on the top cover which can be rotated so you can angle the mist that comes out of it so you can angle it away from electrical equipment or other things that wouldn’t like getting damp.

    I also like that this can be used with essential oils so will be replacing my old diffuser. You don’t put the drops in the water like traditional ones, you push on a drawer on the side, and it will pop out revealing a little tray with a sponge in. You place 8-10 drops of your favourite essential oil onto the sponge and close the drawer. This then mixes the aroma with the mist, and you get a subtle hint of your essential oil. The aroma release isn’t very strong, nowhere near as powerful as a diffuser. If you don’t mind a very light essence of the scent from the essential oil, then you’ll be fine with this.

    The app is easy to use as everything is nicely formatted and easy to find and adjust. I did have an issue connecting it to my network which is secured by WPA3. There are still a lot of products out there that don’t support WPA3, so I’m not surprised at all. I have a network assigned for using just the WPA security protocol for such devices, which this connected to with no issue.

    This is a very attractive humidifier with smart features which can be controlled through the app or even by Alexa with voice commands. It has a big capacity tank so doesn’t need refilling very often and it runs near silently so perfect for the bedroom at night. The included night light gives you purple, blue, green, white and off and gives a subtle illumination. The essential oil aroma isn’t strong though so it shouldn’t be the main reason you purchase this unit. I’m really impressed with this overall

    A very attractive humidifier with smart controls. Essential oil aroma isn't strong though...

The voice control feature is an added bonus, allowing me to control the humidifier with voice.

    Moreover, it is also incredibly quiet, making it perfect for use in a bedroom. I was also impressed with the rapid humidification it provides. After just a few minutes of use, I could feel the air in my bedroom becoming more comfortable and healthier.

    Additional information:

    If your home wifi is configured to use the latest WPA2/WPA3 security you may find that the app won’t let you add it to your network. I had to create a special wifi network which only supported WPA before it would let me connect the Oasis Mist to my network. Not the end of the world – but a little disappointing.

    This humidifier is nice and quiet when in use and could easily be used whilst sleeping.

    The tank is 4.5L which is large and can last for quite a while before needing to be refilled essential oils can also be added to the water to make a nice smell, the water is easy to see so you can tell when it needs refilling. I love the 7 different colours this has when being used it could be used as a night light too, but the lights can be turned off if you did not want to use them.

    Overall I am very happy with this and the room feels less dry.

    We have been heating our house with wood burners and our air is a lot drier than normal and found we were getting sore throats.

    Been using this at night in the bedroom and has improved the situation. Controlled by the app it can tell you when it’s empty although it’s pretty easy to just look at it and keep it topped up.

    It appears it does what it says it does! It does have some noise but unless your really sensitive you probably will get used to it and it becomes background whirr.

    Work for us.

    I got this for the dry season. Operation is fairly quiet and becomes white noise. It is a relatively large humidifier with capacity for up to 4.5L that can increase humidity even in larger rooms. It has an auto shut off function which is reassuring.

    It has the unique function of bring a smart house product. It uses an app for various features but there’s no way for me to test accuracy of humidity calculations. The appearance is modern, plastic to touch with a transparent water tank and a display screen. It takes a bit of space on the counter as it’s bigger than the photos suggest (check dimensions instead). It is helpful to relief symptoms of issues with sinuses or lung conditions.

    Fantastic and nice to have in your room.
    4.5L water tank is plenty big enough and can last upto 4 days. Can be voice controlled using VeSync app that download will be required.
    Lovely lights and very calming
    Was easy to set up and comes with user manuals if needed.
    Great oil diffuser
    I do recommend and worth the price

    Sometimes you can determine an items value almost instantly, however some things take a little longer to evaluate, that’s the case here and to be honest whilst i’ve utilised several dehumidifiers in the washing/drying room, i’ve never utilised an actual humidifier so wasn’t really sure if it would be beneficial or not.

    This item arrives boxed in a branded cardboard box which is suitable for gifting, this contains the actual humidifier, instruction booklet, cleaning brush and some replacement filters.

    This is a rather large device, which looks rather like a small tower pc from a distance, this isn’t a bad thing but whilst it makes for an aesthetically pleasing product and allows for some of it’s design features to be fully utilised, it also should be pointed out that you will need a suitable and available surface to place it.

    The humidifier has a 4.5 L water tank, which in the scope of humidifiers is pretty large, this is easy to refill without removal and you can view the remaining water level through it’s transparency, the device also utilises this transparency to utilise it’s included night lighting.

    The item has a wood effect cover which incorporates two dispensing nozzles, this can also be removed to facilitate filling the water tank with water, the device can dispense either warm mist or cool mist and dispensing is rather rapid with a detailed panel to depict the current humidity level.

    The item incorporates aroma pads for use with essential oils, it also includes a replaceable water filter within the device, both of these replaceable items are currently available from amazon in their respective packs at a sub 7 price point which represent great value.

    The item can be completely stripped down for cleaning, removal of the water tank, water filter, sponge, mist channel, noise silencer and aroma box is easily achieved and when you undertake such tasks it’s instantly apparent that a lot of effort has been placed into the design of this device.

    The device itself functions well, it takes very little time to dispense it’s fine mist particularly if utilising the warm mist setting, how much difference this makes to your household however will depend on your lifestyle choices, if you have heating on in a room for long periods then this item will make a huge difference to that room for example.

    There is a free app available namely VeSync that can control the current humidity, timer and lighting on this device and it has integrated voice control with Alexa support.

    This is an excellent device which whilst aesthetically pleasing, also functions well and provides some additional features which although not a requirement to the products functionality, are nevertheless welcome additions, the fact that the replaceable items are available to purchase directly from amazon and the implementation of easily removable components when cleaning makes this item difficult to fault.

    The only question lies not with the product, but your individual household and how much you need it?

    This is a fantastic humidifier. Very quiet and easy to clean. With the app it even notifies you when empty. It monitors the actual humidity and operates at multiple mist amounts. It can be controlled by the app to turn on and operate all functions. This is a 4.5 liters tank so it last 12 hours or more. I clean it each time I change the water. Has stopped dry nose and throat and dry skin. My husband was having nose bleeds but the moisture in the air has stopped them. Pleased with the product.

    This is an excellent humidifier. Used to increase a rooms humidity quite quickly.

    Love that you can choose your colour of night light and you can even add your favourite essential oil.

    Love how easy it is to add water.

    An all rounder very good humidifier.

    A humidifier is a must in every household nowadays. It improves air quality by hydrating the air. , I can feel that it is different from my previous air purifier as it can be used as a night lamp with different light colours to choose from and an aromatherapy diffuser.

    The device has a pretty big 4.5l capacity. In my opinion, one of the coolest features is that you can control the device via an app called VeSync. It also has a digital display which is very easy to use and read. I like that the device has cool and warm mist to choose from depending on your needs.

    After using it for a few days I can confirm that The air in my bedroom feels lighter and more refreshing, something like a breeze. It is pretty quiet. I have it near my bed, and while it emits a gentle hum in use, it’s neither loud enough nor whiny enough to be any problem at all. I happily leave it running overnight and it neither stops me from getting to sleep nor disturbs that sleep once I drop off. And I’m a very light sleeper.

    Overall, it is a brilliant device, not the cheapest but the quality is spot on.

    Great device, does the job

    This arrived in a simple cardboard box, it has the humidifier, instructions, warranty information, replacement filters and a small cleaning brush.
    This is a large humidifier but aesthetically it looks nice in the corner of the room. You can see the water level inside through a transparent plastic tank and it has a lid which although looks like wood is actually made of plastic which makes it easy to clean.

    I like that is has an automatic mode which will control the amount of moisture released which is great for leaving this on throughout the evening. The tank is large enough to keep this running all night, however if you do forget to turn it off it will automatically shut off once the water has been used. Refilling the tank is a breeze, it’s removable with a carry handle so you can just take the tank and fill that without having to unplug the whole machine.
    I also like that you can use essential oils with this, however be aware you do not put the oils in the water, they go on a sponge inside a compartment which is easy to access.

    For us the massive bonus of this product is the app function and the integration with Alexa, it allows us to control and monitor the device when not at home and also turn it on just before we return home.

    This is a more expensive humidifier but the smart technology functions justifies the extra cost.

    Really impressed with this product. It is also really quiet which is great.

    Golden Review Award: 22 From Our UsersI bought this due to having a bad head cold and cough. It’s much bigger than I thought using it for the first time last night I slept right through it really has helped its also very quiet. There are only 2 things I don’t like is that it is a bit big but the most I’m bit upset about is you can’t dim the light I can’t sleep with lights on and it’s a shame because the colour of the light us very soothing just a shame you can’t dim it slightly otherwise this is an event product would recommend
