  1. Celi –

    I’ve had it for about a month now and So far it is working great!!

  2. DonDon7 –

    It’s great for a small room. I love that it last for 30 hours.

  3. TOOL8T –

    Thought this would be a bare minimum humidifier but it works better than expected! Water storage is more than i thought and the blue night light is nice to have right before bed

  4. Bal77 –

    This is a great item. I love the slick design and works good in closed room. Been using it for a few days now cuz of my sinus and it helps alot. It is not that loud and dont take up much space so I would advise n e 1 with sinus to get 1

    A few months ago, I purchased a larger humidifier for my bedroom that is from this particular brand at Costco and I loved it so much that I decided to buy the smaller one on here for my kids. So far I am very happy with my purchase. This the quietest humidifier we have ever owned and we have owned several brands over the years. It also doesn’t seem to grow as much mold as previous ones have due to the type of material it is made with, so there is no smells or pink mold at the base. I have purchased the decalcification filters from Pure Guardian’s site as I live in an area with hard water and I have noticed that helps a lot with white dust. This particular model has a nice light that my kids love. My only complaint is I wish it had more settings to control the output. This model only has 3 settings and you adjust by pushing the main button. Overall recommend this brand of humidifier.

  6. Vidoe –

    Excellent product. Works well and love that you can add your aroma oil!

  7. Merdan –

    I can breathe in my room much better than i could before.

  8. joeysmom –

    This barely holds enough water for 4-5 hrs of humidiying. Hard to clean, and the vapor spout was sometimey, Someitnes it had a great stream of mositure and someitmes not.

  9. Radman –

    Great humidifier for the bedroom. Easy to use and works great

  10. Water –

    This machine is easy to use, very quite, and makes the room cooler

  11. Alexg –

    Does the job well, if you have it on level 2 or 3 you’ll have to refill it daily.

  12. XiJingPong –

    this thing is the best of its class.
    Works great.
    I wish I had this thing years ago.
    I’ve already bought two of this thing and might even buy another.
    Grate product for people

  13. Kiddo –

    This is a nice little humidifier if you have a small room. Instructions are very clear and easy to use.

  14. ALF2017 –

    It is a nice humidifier, but I wish I had purchased a larger capacity one.

  15. FrequentUser20 –

    Pros: It’s a lovely shape with blue night light and lasts for over 8hrs.
    Cons: The water tank doesn’t seal completely so it took a while to get used to the loud gurgling sound of the bubbles escaping into the main chamber. It’s tricky to fill because of the unusual shape and bulky size of the main tank. You have to clean it diligently to get rid of the pink fuzz that accumulates in all the nooks and crannies. The oil tray is always wet and it’s not clear how the oil dissipates into the main chamber so stopped using it.

  16. Lisa –

    Really helped with my congestive nose. Also was a good edition to helping my room glow at night.

  17. Mamamato –

    It’s quite basic. It lacks the option to change the amount of vapor for when the air is drier. It hasn’t been doing much for my bedroom (11×15), but it may work better for my daughter’s smaller room. You might need to put this right beside your head on a nightstand to notice the difference.
    There is an essential oil dish at the bottom. It works very well. Not as strong as a more robust essential oil diffuser, but enough to notice the difference.
    This is a bit of a hassle to clean for the design of the inner tube, but it’s very easy to fill. You will need a bottlebrush set to clean this properly. The Honeywell (Model:HWM845B) cleans a lot easier.
    I never use the nightlight, but it is nice if you need it.

  18. Sharong –

    Great product the only issue is cleaning the inside. Price wise affordable.

  19. Moomoo –

    Very quiet and efficient. Easy to fill. The blue light can serve as a night light.

  20. prphtess –

    Each fill lasts a long time, satisfied with multiple output options.

  21. Unknown –

    I really like this humidifier which also can be used as diffuser

  22. Snax –

    I got this for a friend who has a small space, She loves it and only has to fill it up once a day. Totally recommend. Actually should have gotten one for myself and might for my bedroom,

  23. Amazing –

    Very OK humidifier. Very complicated to fill it up as the bottle is too tall and you can’t actually fill everything (you need a deep sink for that). Overall does the trick if you are looking for just mist!

  24. Novos206 –

    These work extremely well, especially where I am located where it is super cold during the winter and dries out the air. They will run for 24-hours but only on the low setting.

  25. NONE1 –

    Excellent humidifier. Silent and efficient. Works easy. Easy to refill. Pocket for flavory oils.

  26. Havenn –

    Perfect size and capacity to use in the guest room.

  27. Oleg –

    Good product, but not worth the money. Many features still need to be worked out.

  28. Jlaw –

    I love this humidifier. It’s very easy to use and clean and it helps me on my seasonal allergies. I recommend this product.

  29. RickyE –

    Excellent product no issues easy to use,great quality

  30. Sinner –

    I like, although to small and water is gone quickly. I don’t use as often due to water issue.

  31. Awesome –

    First time to use a humidifier and it work really good ,love the light.

  32. HappyTVbuyer –

    I use this in my office and it works great! I talk on the phone a lot for my job, so the extra moisture in the air helps prevent sore throats.

  33. Laurie –

    This is my second puregaurdian cool mist humodifier. My first one i bought many years ago and it still.works well. I just needed a bigger one. It fills easily. Has a big on button and a sepperate button for the night light. It is very quiet. On low it does last over 24 hours for sure. I fill ot about the same time every night and it always still has some water left. It also has a oil pad on the side if you want tonuse essential oils with it as well.

  34. DBad92 –

    This is a great product. It works well even though it is smaller than the one I had before. It’s simple to use and I enjoy the soothing blue light it gives off. You can leave the light off if you choose.

  35. Betty1979 –

    Wouldn’t recommend this humidifier except for being inexpensive. Difficult to fill, mist doesn’t spread evenly, and larger than expected.

  36. mike –

    Great, product. I really love it and it works great.

  37. Paulad –

    I have not even had this for one month and the power button literally fell inside when I pressed it just now. I cannot even get it out. I am so tired of spending my hard earned money on things that break right away. Ridiculous.

  38. Pasha –

    Since I bought it I only turn it off for a water refill so it works 24/7. I like the design and options which it gives for the price. The only thing I’d change – a button light – too bright. I’ll probably put a sticker on it cause it stands on a bed ide table now and it’s too bright at night

  39. Ruby –

    Very good humidifier and has three settings. Although, the water does run out quickly and you have to refill it often.

  40. Ronron –

    Very quiet,very cool humidifier and easy to use.I recommend this product

  41. Bluell –

    Love it. Completely quiet, I sleep with the unit about 20 inches from my head and only hear an occasional gurgle. On the high setting the tank empties in about 8 hours. Easy to fill. Only complaint is how bright the light is on the power button. Have to cover it with cardboard at bed time.

  42. Luv2dance –

    I’ve been using this for a year and this winter was a lot less dry in my room

  43. SGDC –

    Great choice for a room humidifier. Really quiet and it only needs to be filled once a day if used on the lowest speed.

  44. Techguy –

    While it works for a long time, it doesn’t seem to make a noticeable difference in humidity until quite a while of use. I used a hydrometer to gauge. Humidity went from 30% to 40% but took hours.

  45. TheFirstJosh –

    Worked pretty good for the price but would t try again

  46. KeishaD –

    Smaller than expected but it does the job very well. Refill is a chore because of the size. I totally misread .5 gallon for 5 gallons… lol

  47. Pojesama –

    Pro: Easy to fill & use. Con: Refilling at least once daily.

  48. ReviewNut –

    I like this humidifier because it works fast, has 3 settings, and holds close to a gallon of water. My wife and I used this for maybe 2-3 days and realized we do not really like the glowing blue light around the button, as we like to keep our room pitch black dark. Otherwise, its great! It is just not for us.

  49. shopper –

    it is very big in size. it does not take as much water as i thought. it does what its supposed to do, but a little too big for me. the water caraf could be larger

  50. AlwaysHappyatBestBuy –

    This humidifier is as easy as putting water in it and turning it on! It also comes with an oil diffuser and it has a night light! Perfect for children and adults alike! I will be purchasing another one for my sons bedroom!
