  1. Rhlala

    When I first took this out of the box it kind of felt flimsy but I quickly changed my mind when I filled it with water and turned it on. When we run a humidifier in our bed room we always still need to run a fan for the white noise white reduced the humidity being put out but this machine is both the fan and humidity all in one. Plus you can drop essential oils in the top! So easy to clean and holds a lot of water. Other machines specify you have to use special distilled water but this uses plain tap water! So awesome I love it!! [This review was collected as part of a promotion.]

    Mainstays 1 Gallon Cool Mist Humidifier, in black, is aesthetically pleasing.

    The look is very modern and chic. Fits nicely in my room. There are 3 settings, 1 for low, 2 for Medium and 3 for High. On High expect to refill the filtered water at least twice in one day. Yes, it is best to use filtered water with this humidifier.

    There is a fan atop the humidifier and located upon it’s vent, is a small square that has its on lid/vent. Gently lift one of its 4 corners and add your oil, it’s like having an aromatherapy and humidifier in one. I added a room fragrance oil to mine and noticed that it keeps the odor out of the room. The fragrance didn’t fill the room, but it certainly removed the room odor.

    There is a warning light, that is to shine red when the water is low. Which is a nice feature. I can’t say how bright it is, due to I usually turning the humidifier off, when I notice the water becoming dangerously low.

    It does what it says. I notice the room’s air doesn’t feel stagnant or dry.

    Yes, I’d recommend this. [This review was collected as part of a promotion.]

    Easy to use and assemble this humidifier is the perfect size to put in any room to help clear the air and make it easier to breathe. I use this in my own room as well as the kids when they have a cold and stuffy nose. It holds 1 gallon of water and can add oils to the fan part if you’re oils like for a great calming good smelling room. It’s not loud and easy to move around. Has three settings from low-high. Rechargeable filter as well. (Recommended after 30 days of continuous use) [This review was collected as part of a promotion.]

    We have been experiencing cold weather since Fall has arrived. The Mainstays Cool Mist Humidifier helps add moisture in my home. So the air isn’t as dry as it has been in the past. I put it in the hallway of my home and the cool mist reaches the bedrooms. My family has been sleeping so much better throughout the night. There are so many benefits to owning this humidifier. The moist air makes my home feel warmer and more comfortable on the nights I have to use heat. I don’t have to turn it up as high, so I’m able to save on the electric bill. I never knew the advantages of using a humidifier. Now that I know, I don’t think I can live without it. [This review was collected as part of a promotion.]

    This cool mist humidifier is lightweight and portable. Since its that time of year to burn the furnace it gets dry and stuffy in the house. This humidifier has three different settings so you can adjust how much moisture you want in the air. I like the low water indicator so you know when to add more. It holds a full gallon of water.. Its fairly quite but can still hear the fan running. The design is sleek and modern. All in all its not a bad humidifier. Easy start up and seems to be helping me breathe better and not feel so stuffy. [This review was collected as part of a promotion.]

    I simply like this new humidifier, it’s lightweight and easy to use. Simply fill the container with normal tap water, and turn on it. It has three settings from low to high. The best part of this humidifier is that it has a small compartment for essential oil for a soothing and relaxing sleep. The water container holds a good amount of water and good enough for the entire night. On the whole very reasonable but good quality humidifier. The filter needs to change, it’s replaceable.

    This cool mist one gallon humidifier model is very basic, and easy to use. I simply remove the water tank reservoir fill with water, reattach to the unit and select one of three speeds by turning the knob switch located on top of the unit. There is a indicator light that will light up red when the water level becomes low. This humidifier has a aroma adding feature, there is a very small aroma tray located in the middle of the grated area, that you access by lifting the cover off and add essential oil to it, replace cover. Even while running on the highest speed setting the sound it emits is not overly loud, I have been running it at night in my bedroom on the lowest speed and the sound is barely noticeable. I have noticed since I have been using nightly my bedroom no longer has that stuffy feeling to it. The lightweight plastic design makes moving from one area to another effortless, but you have to be cautious while moving making sure you are supporting it by placing your hands underneath while carrying as the base comes unattached to the body fairly easily. Overall it may not have all the bells and whistles as other models, but I’m satisfied with the performance. [This review was collected as part of a promotion.]

    This Pelonis 1 Gallon Cool Mist Evaporative Humidifier is the perfect size for our bedroom. The quality of the plastic felt a little weak and it’s slightly difficult and awkward to move once it’s filled with water, but it has perfectly placed handles which are helpful. I also really like the filter placement and how easy it is to take apart and let the pieces air dry completely. Overall, I’m very happy with the product and the simple ability to adjust the amount of mist from 1, 2, or 3. I also really like the auto-shut off feature that activates if it runs too low on water.

    It is not high quality. The cover for oil broke a prong when I removed it. But surprisingly it work wells. It is quiet on the lowest setting. I have not needed to use the higher setting therefore I do not know if it is too loud. Maintains my bedroom at 50% humidity. My whole house humidifier keeps the house at 45% but I like that little extra while I sleep. I have not tried using any essential oil yet with it. It can go 2-3 nights on one tank of water.

    I saw this in my local Walmart for about $22 and thought it was a great deal. When I got it home and took it out of the box I soon discovered it is made with very low quality material and couldn’t get it assembled correctly because of that. I ended up returning it for that reason and am rating it a 1 star for that reason.
