What Owners Report:

• “It took a few days to raise the humidity in an extremely dry room, but once comfortable levels were reached, this machine kept them in the range by adjusting power levels or pausing completely. I love how I can control and monitor it with the app. This humidifier has settings to completely dial-in your humidity preference, either with cool or warm mist. I get a phone notification when it is time to refill it. I always use distilled water or water from my Culligan pitcher with Zero Water filter. I have not experienced any white dust, but suspect you will get some if using regular unfiltered tap water. It is quiet and puts out a plume of mist 4 to 5 feet high. It is easily cleaned, though I haven't had to since I only use filtered or distilled water.” — CSM (Amazon)
• “Love this mist humidifier. Have had it almost a month now and has performed perfectly. We primarily use it in the cool mist mode but the warm mist works great as well with several temperature settings. Keeps our sunroom humidity perfect ,with the set and go percentage, for us and plants during our low humidity season. Easy to use and clean. So quiet you don’t know it’s running except for the mist coming out from the top. Had a concern it might make the floor wet around the humidifier but the mist is so fine it dissipates easily into the air and the floor has not had any moisture. Couldn’t be more satisfied with this purchase. We are planning to replace our other wick type humidifier with this one asap.” — Michael Hensley (Amazon)
• “I’m here to tell you to Get IT! It’s worth every penny. My previous humidifier was basic from Walmart. Just fill it with water and turn knob on high or low and honestly it was okay but this one blew me away!! The app is super helpful in every way. It tells you how many hours you have used it and when you should give it a cleaning. It hold twice the amount of water as my old one. The best part is you can set how much humidity you want. We set ours at 50% and once it reaches 50% it shuts off and waits until it drops below 50 to come back on. There is a tiny slot near the cord for essential oil pad to be placed if you’d like a nice aroma in with yours as well. If the light on the screen bothers you at night you can also shut the lights off in app. 10 out of 10 recommend getting this humidifier. Also, the app send you straight to the website to purchase filter replacements for your product.” — Josie Morrow (Amazon)

What Owners Report:

• “2.5L is good size and good value. Water fills up all the way to the top of tank and runs for approx 24 hrs on one fill. Fits on counter without taking up too much space. Good mist. Enough humidity for small apt. Whisper quiet, and no lights when running, so perfect for a large bedroom. When cleaning, there is a small plastic piece under bottom on tank that unclips, making cleaning fairly easy. Very pleased with this purchase.” — MPTrevino (Amazon)
• “I bought this humidifier for my baby’s room and it has been working great. It’s very quiet, which is perfect for nighttime because it doesn’t disturb the baby’s sleep. The cool mist works really well and helps keep the room comfortable, especially when the air gets dry. One thing I really like is the top fill design. It makes it super easy to refill and clean compared to other humidifiers I’ve used. The tank lasts a long time too, so I don’t have to refill it constantly. Overall it feels well made, easy to use, and perfect for a nursery. I’m really happy with this purchase and would definitely recommend it to other parents.” — Daniel (Amazon)

What Owners Report:

• “So far this humidifier is working great, it's quiet and is keeping my bedroom humidity at about the level I have set it. This has really made an improvement on my quality of sleep, less dry nose or skin and no more nose bleeds when I wake up because my sinuses were too dry before the humidifier. Cleaning is a bit of a challenge because there is a potential for losing one small part that comes off very easy and on it's own, and because of the tank size, but I like the size of the tank because there are less frequent refills.” — Martin Vazquez (Amazon)
• “This is by far the best humidifier I have owned. Its large capacity is impressive and after a couple of days it brought the humidity level up significantly. Starting at 29% it climbed to 40 plus and is hovering around 50%. I use it in a large basement (about 1400 sq ft) to protect my wooden musical instruments and model ships. It shuts down when the preset is reached. I can run it for 24 hrs without having to refill it. The design and functionality are impressive. The best part is I can use tap water and although there is some white dust, it is less than my other humidifier created; AND, probably due to the UV light and filter cartridge, THERE HAS BEEN NO PINK SLIME whatsoever after about a month of constant use!!! I highly recommend this humidifier.” — TED T. (Amazon)
• “This humidifier was a game changer. No more nasty filters to deal with. And it actually raised the humidity in my home to a safe and comfortable one. My house is very dry here in New England during the winter. It is unhealthy to have humidity so low. I knew my small units weren't working so I purchased this to handle the first floor in a 1700+ sf home. I only use distilled water so I'm not getting any deposits on floor or furniture. The air is clean and breathable. Maintains humidity 35% and up. I do go through a lot of water but that's the price I need to pay to keep my home and family healthy. Great light in reservoir so I know when to refill. Easy to fill. Very quiet unit. I have had this running daily all winter. No leakage! This is a powerhouse of humidifiers. A++++” — Tell It Like It Is (Amazon)

What Owners Report:

• “Very happy with this purchase! I use it nightly to help prevent congestion & cough. It uses about 1/2 gal nightly if set on “auto” and the second output setting. I like that you can use cool and hot vapor. I also like that you can control the unit with the VeSync app on your phone. Being able to direct the vapor in two directions is definitely a plus! I haven’t run into any negatives. It’s very easy to clean, but I’m using distilled water always. This seems to lessen the need for daily cleaning. I rinse and dry it about once a week.” — Dean in SC (Amazon)
• “Best humidifier I've ever had and I've had a lot. I like that it is easy to clean, easy to fill, is quiet, has a warm mist option and large capacity. I have learned to use distilled or purified water in any humidifier to prevent mineral build-up (or mineral dust from cold vapor humidifiers).” — Niphty (Amazon)
• “We purchased this humidifier for our cat who suffers from congestion and possibly allergies. Our vet recommended trying this humidifier to see if this would give her any relief. The jury is out on that, but we do enjoy it and makes our room feel very nice!” — Mom on the Job (Amazon)

What Owners Report:

• “As cool mist humidifiers go, this one is easy to clean and operate. One part is a little difficult to remove for cleaning and I have been able to manage. Distilled water is recommended, and you need at least three cups of white vinegar to clean it every three days. I elected not to download the app and have been pleased that the machine works fine without it. The Levoit does a good job moistening the air in my bedroom and it is extremely quiet. Sleep mode shuts down all those annoying LEDs! My only issue with the humidifier is that because the touchpad buttons are flat and don't "give" when you push them, and there are no haptics associated with them, if the unit is in sleep mode (no lights, operating according to humidity level in the room), there is no way to tell if you've successsfully turned it off. I found myself blindly pushing buttons more than once.” — Wendy Ohio (Amazon)
• “I love that I can start using my humidifier right out of the box. No difficult setup or making sure parts are placed properly. I just plugged in, filled with water, and started it. I downloaded the app, vesync, and quickly created an account. I was easily able to sync the device to my wifi and connect to the app by pressing one button. From the app, I can control the settings such as desired humidity levels. When I set to a specific humidity level, the device auto shuts off at 5% above and auto turns on at 5% below. If you're looking for an affordable, easy to setup, and precise humidifier with a large water capacity, this is my recommended product!” — Rachel McCall (Amazon)
• “This has been a great humidifier. I have had this for over a year now and I am pleased with how well it works and has held up over time. This unit has a really big tank for water storage which I really enjoy. I like that I don’t have to refill the water each time that I use it. So that is a bonus. It has adjustable settings, a night time mode where you can shut the control panel lights off while you sleep and it also has a neat nightlight option which is really handy. Overall very pleased with this humidifier compared to others I have purchased and used in the past.” — Cassie (Amazon)
