It looks good especially with the blue glow and it is very easy to use. It can be infinitely varied to suit what you want. The only thing it doesn’t do is measure the humidity although to be fair none of them do. It would be a good idea to purchase a Hygrometer so you can set it to achieve a target humidity and take some of the guess work out of it.
Amazon Customer –
Good product overall except the pads for aromatherapy oils were missing.Have contacted supplier about this.Water tank is large so I don’t need to keep filling it so often.Very low noise level.
Linda Robinson –
Easy to set up and use . Portable throughout the house as required, if water compartment not filled.We changed from oil to gas heating and found the air very dry in the house, the humidifier really helped with this.
Geri –
I’m really glad I bought this – adding Olbas oil makes the air feel generally fresher and cleaner. The only thing I’d comment on is it’s not hugely easy to refill, but I would still purchase it again.
Jackie burton –
It works really well and does what it says it does
John J –
Very quiet, fiddly to fill but overall good value
L E POLTOCK –
Works very well, exactly as expected. Neat, easy to use, very quiet.
MJC –
Very efficient, lasts at least 2 days on minimum setting. I liked my previous humidifier but this one tops it, so happy purchaser!
Amazon Customer –
This humidifier is fantastic. It is quite large but don’t let that put you off. It’s not noisy at all so does not keep you awake at night. I cannot recommend this item enough. Don’t hesitate to buy it.

I have COPD and I was told to buy one because people said the very good

I bought this product because I fell ill with COVID-19 and at one point couldn’t breathe properly. It was very easy to put together and has a calming effect when in use (I leave it on overnight when I’m sleeping). I am very happy with this humidifier and have told my friends and family about it. I bought essential oils to use with it – once my sense of smell returns I’ll be sure to test that out, I’m sure I’ll love it!
gamegal –
Lightweight and easily portable, but mighty, this machine has already helped us breathe better! (We jokingly call it “Lil Steamy.”) It was so easy to set up and use, and easy to move from one room to the next (the instructions caution you to wait til it is empty to move it, but I have moved it with a tiny bit of water still in it and it was ok). It is quiet and really keeps the room air in good shape. And it did not cost a fortune! Top rating.
Gary C. –
Early days yet but first impressions. I bought the product because I read that if one was unlucky enough to contract COVID-19 then having a humidifier operating in the same room as the patient could be beneficial.We have not been ill (yet) but I’ve been running it in our bedroom at night because of the reported sleep benefits. It was very easy to set up and has a fairly large capacity reservoir so it will run for 4 or 5 nights without requiring a refill. It is also very quiet which makes it ideal for a bedroom. The ambient light can be operated independently of the humidifying function should it bother you.It operates exactly as described on the tin but are the reported benefits real?The honest answer is I don’t know yet – it is possible that the two people sharing the bed have not been snoring as much! And I feel that I have slept more soundly over the last few days.I will update this review in a few months time with a more considered opinion of the reported benefits.

Fab product,kicks out loads of cold steam,perfect for asthmatics
Mercy –
I had this terrible dry unproductive cough that couldn’t be treated with anything… not syrups, not lemon and ginger concoction, not hot steaming … nothing! Everything I use to sooth a bad cough failed this time . After several nights of sitting up and night and not being able to sleep because of this terribly irritating cough, the light bulb suddenly and finally lit in my head… I should try a humidifier! I immediately grabbed my phone opened the Amazon App and started searching. I eventually settled for this and I must tell you quite frankly , in the first 10 mins of use my cough literally disappeared! It was like magic.To convince myself that it was the humidifier at work, I switched it off and the cough started again. I switched it on and the cough stopped! I used it for about 10days before the cough disappeared completely and now I can sleep without it.It’s quite easy to use and if filled full can last for two nights.However the design is defective because it doesn’t give you room to wash the inner compartments so when you have limescale and other nasty stuff building up inside , you can’t get rid of the stain and that just gives it a messy appearance.NB- I didn’t get a remote control in my package . So you owe me that seller .

I bought this item to help with the air quality in my home where I believed I had symptoms of the covid19. I found that the night air seemed to be dry, (although no heating on) aggravating the sore and sinus. The humidifier did help. Making sleep a little more comfortable.I am looking forward to using the equipment in summer months and perhaps some aromatherapy too.
Mrs. E. Y. Walsh –
I got this for two reasons: one was for my cat who has upper respiratory problems and for myself because I have asthma and the central heating seems to aggravate it. It’s really really helpful. The cat and I are not so blocked in the nose and my breathing is better because I normally snore
and I listened to my pillow app and no snoring. Very happy
Zooney –
Pros:Very large so lasts many hours and can humidify a large spaceNot too noisyAdjustable level of humidityI haven’t had a mould problem that many other are complaining about- just make sure you rinse it properly after use and add clean water.Cons:So on first use I was PISSED. It was leaking water all over the place. Then I realised you have to remove the top to add more water in your bathroom or sink because water collects in the machine. So if you try doing that in your bedroom for example water will go everywhere. I think it is meant to be used like this which isn’t convenient. This is also extremely dangerous if water were to get onto the plug socket!Design wise I think its flawed- it would be so much easier to just add water from the top or something. Instead you have to lift the entire thing, turn the top upside down and put water into it. I am lazy so this is very inconvenient so many times I just can’t be bothered to use it.You also have to make sure it isn’t too close to any surfaces if you have it on the highest setting, because it will leave water on your items. Possibly even the plug socket! So have to make sure it is streaming in opposite direction.Hygiene wise you have to ensure that it is always clean otherwise I think it will just be spreading germs and bacteria all over the place. I also think that if there is viruses in the air surely it will help it spread?I bought it to help with my dry skin. I don’t think it has helped with that at all.Therefore I would give this item maybe a 6/10 overall.

I’m delighted with this humidifier. I have been using it for a week now. Since using it I haven’t been woken with my ‘tickley’ cough which I’ve had for over a year, and my mouth is nowhere near as dry as it usually was in the morning. There is the sound of the Waterfor a second at various times during the night but this has never bothered me. It is quite easy to fill. My husband helped me the first time with cleaning it as recommended but I’m sure I’ll be able to manage on my own. When you take the reservoir off to fill it, be careful as there is some water left in the tray.
Laura Hitchcock –
Really easy to use. Not so easy to fill up the tank to the top unless using a jug/funnel as you have to tip the tank to the water flow. I don’t find that the scent is that great. The noise helps me get to sleep and I find my nose isn’t so stuffy when I have it on.
Chris Houlihan –
Can stay going for the 40 hrs was quiet surprised . Great product
Mrs. L. Lawrence –
This is EXCELLENT! The large water tank means it keeps running through the night and some. It’s really quiet and easy to adjust the flow and direction of mist. The night light is handy if waking up during the night. Impressive piece of kit for the price, I’m actually thinking of buying another one for the living room.
LindaMac –
Does an excellent job of humidifying the central-heating dried air in a medium-sized room. Completely silent, apart from an occasional quiet gurgle as water goes from the tank into the base unit. I don’t use it in a bedroom, but it certainly wouldn’t keep anyone awake. It’s very adjustable, and on full power it works to re-humidify a dry room fairly quickly. The fact that it is cool mist makes it very safe to use around animals or small children.If, like me, you live in an old house with no double glazing, and it’s warm inside and cold outside, you will get some condensation on the windows, but it’s not really a pain to wipe up any that runs onto the wood. I suspect the condensation is less than would come from warm steam. The tank is a bit cumbersome to refill, but the machine runs for up to 40 hours on one fill, so it’s not as if it needs to be filled every few hours. Very pleased with it all round. I have some allergies and my dry eyes and stuffy nose have virtually disappeared using this.
Steven A. –
I ordered this product as I have been looking for a humidifier for a while now but most are really overpriced. This one was a great price and is worth more than what it’s being sold for! Extremely easy to use and fill up etc. I fill it up usually around 5pm and leave it on until the next morning and there’s usually still quarter of the tank left. Very quiet as well so doesn’t interfere with light sleepers like myself. Highly recommend!
Bev –
I bought this humidifier after seeing on the web that they help with dry sinus problems. I have had flu since I purchased it and cant yet say it helps with sinus issues but it has really helped with congestion caused by flu, especially overnight. I have already recommended to friends. It was a bit bigger than I thought it would be, but that will save me filling it up as often. The blue light switches off and the slight noise it makes is not intrusive.
Amy kane –
Reccomend this humidifier, I had a smaller one before but wanted a bigger one, when I wake up it is still half full, the reason I need it is because I suffer with dry skin, I can say it helps, the only negative thing I would say is you need to be careful because it can leak water if you move it, also if you leave the volume too high it can make the floor wet but other than that it is a good buy, decent quality and makes the air in the room nice and fresh
Amazon Customer –
I purchased this to help my husband who has various lung conditions. As he coughs during the night we thought this would help. It is helping already and I am pleased we made this purchase. I wish I could have found one at this price before.
D G Forbes –
I really love my humidifier, it’s easy to use and a single tank of water lasts for ages. I also bought essential oils which I insert into the aroma tray and it gives a wonderful lasting scent throughout the room.I will definitely purchase this item again and it can also be used in all rooms (apart from the bathroom!!)Thank you

R F –
I bought one of these and it worked OK until I refilled the tank, then it just stopped producing mist. I contacted PureMate and they immediately sent a replacement – Top marks for customer service!. The new one works well. There are more powerful humidifiers on the market, but this does the job.
Freya –
Bought this after wanting a humidifier for a long time. My partners mother actually bought before me which we borrowed when we caught a cold. Overnight we both felt amazing after a week of feeling crap and have since bought the exact same model.We feel like we slept better, our skin is more hydrated (Both moisturiser addicts but reduced use dramatically when waking up with more hydrated skin) and our hair is in better condition, and the house plants also seem to benefit!This product hold enough water for 2 nights (7-8hrs) on a moderate/high setting and almost a week on a lower setting, though would recommend changing the water regularly.The addition of the essential oil tray means we can add oils to suit our mood and fragrance the room (lavender lovely whilst sleeping, eucalyptus and tea tree when we were ill etc).Very easy to use, refill and clean – our previous unit had been left partially filled and Unused and had developed a few mildew-ey spots, but hot water, soap (and disinfectant just to be sure) and a dishbrush got rid and the unit looked brand new and functioned perfectly once again.The product is near silent except for an almost inaudible whirr and the occasional bubbling sound but this proves to be perfectly relaxing to drift off to sleep with. The cool blue LED looks great and can be turned off for nighttime.The vapour is cold as expected, but I will be cautious of keeping the room well ventilated in between uses.TL;DR love it, have recommended to others and will but again if this ever breaks down
susannah mcallister –
Great would really recommend this. I put it on in my bedroom and added a few drops of lavender oil in the diffuser tray just before going to bed and I had a great sleep.The price for this is a bargain and because it had a larger tank it doesn’t need filled as much as the other brands.The added light adds to it’s appeal.
Chali Atkinson –
The media could not be loaded.
As per my video I am really happy with this humidifier and would recommend it for any home. The noise level is really low and I am a light sleeper and have had no problem.
Peter Still –
Really pleased with this humidifier, which ticks several boxes in my requirement list, and then some. Nice large capacity water holder and easy to fill. Powerful mist producer the output of which, importantly, can be adjusted to suit via a handily located large dial on the front. (It would have been nice to have a similar fade up/down facility for the pleasing incorporated ‘blue light’, which functions via an on/off switch; a bit bright if you’re hoping to use it as a gentle snoozing background light for the bedroom, which I’m afraid it isn’t. I’ve had to shield the glare with a cushion propped up against it. However, the unit’s many plus points overwhelmingly outweigh this minor inconvenience.) Also crucial is its quietness: the noise level is virtually non-existent – a huge plus. And then, the icing on the cake: an easily accessed slot for adding your choice of essential oils as desired. Importantly, the oils do not mix directly into the water but, instead, the aroma is drawn up into the mist: the result is a pleasing constant background essence and is not overwhelming. All in all, I’d have no hesitation in recommending this excellent humidifier as a boon for any size room you may like to humidify.
mrs. frances williams –
Brilliant product. So easy to fill and lasts such a long time. After a really bad cold I always suffer with sinus problems, but after 2 days using this the difference is amazing. Not saying it has gone yet but getting there. So much better than taking tablets.
Felicia –
Works perfectly!
Anca –
Bought one for my daughter’s room and it’s doing a great job! Really quiet and the night light isn’t too bright either. I use mine with essential oils and I have to say it’s way better as the smell is subtle and helps to refresh the air. As another person said, it is on the large side, so it might be worth thinking about that when buying. I had a few issues with the first unit and had to contact the seller’s customer service and within a day my problem was solved. Very polite and helpful! Would definitely recommend!
Vikki Thomas –
Love this product, better than having a fan in the bedroom. It’s very quiet and the misting on your face as you sleep is cooling. Suffering with bad hayfever this year and this product helps me breathe in the night so I don’t wake up with a blocked nose and a dry mouth
Amazon Customer –
Reqlly good product
M.J. Blunden –
Cannot review scent as don’t use that. Just use as humidifier with clear water and it works extremely well aiding breathing. My husband suffers from sinus problems and I am asthmatic and although we have only used this for 2 nights we have found benefit already.
Franco –
This is a great mist humidifier. I got the 3,8L and it does the job. I have been suffering from nasal problems lately. With this on at night. I have been having a good sleep. I bought Essential Oils that they say is good for nasal problems. A few drops in the water before use.The Humidifier is very quiet, you won’t have a problem falling asleep.Delivered well before the estimated time.In the review, it says remote control. IT DOES NOT HAVE A REMOTE CONTROL
Shaq A –
I’ve had this for about a month now and I can’t believe I didn’t buy a humidifier earlier. Using it on max setting usually lasts a full 8-9 hour sleep and I feel like it does help with chapped lips when it’s cold.The noise is kind of like a minor hum which is peaceful to sleep to.One thing I wasn’t prepared for was the cleaning. I didn’t use it daily but it got a bit dirty inside. I followed the steps from other reviewers (diluted bleach) which did help but the actual plastic body of the humidifier was harder to clean – I eventually used a small old rag and then shook it like a cocktail. Helped remove any muck inside.All in all, great all round humidifier. Little hard to clean but I think most humidifiers would be
James Oneill –
Fill it up and it will last between 2 to 3 nights around 16 hours you get instant humidified air great for my sinus condition,its extremely quiet as well so it can be left on all night on the bedside cabinet.A built in blue led light can also be switched off at night
Mrs M. –
Bought this product for my son’s bedroom to help ease his asthma and allergies and have been very pleased with the results. The humidifier is very quiet when in use and has a large water tank. Easy to assemble and clean , simple operating instructions and a very competitive price for such a good quality product. Highly recommend!
Sara T. –
Everything is good. The only problem is the light.
Victoria Louise –
My daughter developed croup one week after her brother came home from hospital. At the end of my tether with sleep deprivation, I bought this. The first night it was on she slept through until 5.30am, having not slept for more than an hour for the previous 5 nights. The second night it was on she didn’t wake until 6.45am. It is not coincidence…would thoroughly recommend.
Lisa Wilson –
I’m very happy with the size, only need to refill every third day using it at half mist power. I also like the filter which can be easily cleaned with some vinegar. I’m not happy that it makes a dripping noise, like a leaking tap, but it’s not as bad as others I’ve tried and I was able to get used to my noise machine going up one level to cover the noise. Without the dripping it would be very quiet.
Charlene Wellington –
I love this humidifier, it is a really essential item during the hot summer months.
Margaret –
Extremely glad to have bought the product. My only downside is the filter is hard to take off at times
nidhi –
Excellent humidifier, does the job well. Barely any noise but the tank filling can be made a bit easier but it actually doesn’t affect the working of this humidifier.
lozzie –
This has worked wonders for both me and my partner. I was always waking early hrs coughing and my partner waking with a dry throat needing a drink of water. Since using this for just over a week, none of us have ailed anything from the first use, no more coughing and no more waking for a drink of water. The air feels alot fresher and cleaner. I’ve been using the eucalyptus oil in the drawer, i switch it on an hour before bed and when we walk in the room it instantly feels fresher and we switch it off in a morning. It’s probably on for about 9hrs. We’re having restful nights now as opposed to restless nights. I would definitely recommend especially now with the heating on for longer periods of time and with cold and germs going around.
