LEVOITHumidifiers for Bedroom Home, Smart Warm and Cool Mist Air Humidifier for Large Room, Auto Customized Humidity, Fast Symptom Relief, Easy Top Fill, Essential Oil, Quiet, OasisMist4.5L, White

I recently bought the Levoit OasisMist 450S Smart Humidifier, and it has honestly changed our lives—especially for my daughter. She used to get sick often during the winter with constant coughing and congestion at night. Since using this humidifier, she’s not feeling nearly as sick anymore, and her nighttime congestion has improved dramatically. It even helps reduce her cough and cold symptoms within just one night. I was blown away by how fast it worked.What I Love:• Warm & Cool Mist: We mostly use the warm mist at night, and it’s been amazing for clearing up stuffy noses. The cool mist is great during the day or in warmer weather.• Smart Controls: I use the VeSync app to control everything from my phone. I can check humidity levels, set timers, or just adjust the mist level without getting up.• Auto Mode: This is one of my favorite features—it senses the room’s humidity and adjusts automatically, so I don’t have to think about it.• Large Tank & Top Fill: The 4.5L tank lasts through the night and then some. Top-filling is super convenient, and it’s easy to clean.• Quiet Operation: It runs silently, so it doesn’t disturb my daughter’s sleep at all.• Aromatherapy Option: I add a couple of drops of lavender oil at bedtime, and it helps create a calm, spa-like vibe in her room. We use the aroma box regularly, and when my daughter is sick, I put Vicks drops on aroma pad and place it near the nozzle. It works like a charm to open up her airways and ease her breathing overnight.Final Thoughts:If your kids struggle with winter colds, coughs, or nighttime stuffiness, I highly recommend this humidifier. It made a noticeable difference after just one night, and it’s now part of our daily routine. Levoit really nailed it with the OasisMist 450S—worth every penny!

I ABSOLUTELY and without a doubt love this "Smart" Humidifier. It was not easy to put together the first time and you might have to go online and find a video or pdf user manual to help. Otherwise, well worth the money. Levoit is the way to go. QUIET. When it feels dry in my room I say, "Alexa, turn on humidifier". It measures the amount of humidity in your room and will automatically shut off when it reaches a certain level of moisture in the air. I love love love that it has a Sleep Mode. I suggest using distilled water in the tank. No need to fill up the tank; half way will do.

When I first started using a humidifier, I relied on those cheap models that barely produced any mist. I never knew the actual humidity level in my room and just went with whatever it could manage. Despite using one, I still woke up with a dry nose, sore throat, or cough. When I saw the price of this humidifier, I hesitated, but I ultimately decided it was worth investing in a high-quality product rather than another ineffective, budget option.I’m so glad I did. While the extra features like Alexa integration are nice, the real standout is how well this unit works. Our home, an older house with poor insulation, typically sits at around 20% humidity due to East Coast weather in winter. This humidifier can raise that to 55% within an hour and has even reached 70%, which is impressive given how easily air escapes from our home.If you’re considering this humidifier, I highly recommend it. However, if you have hard water like we do (we’re on well water rather than city water), using distilled water would be ideal if your budget allows. The unit reminds you to clean it more often than necessary, but ignoring the notifications for too long can lead to calcium and mineral buildup, which affects performance. Additionally, if you use well water, you’ll notice a fine dust settling on surfaces—this is just mineral residue. If that bothers you, distilled water is the way to go. Otherwise, if you don’t mind the minor buildup, well water works just fine.

PROS:* Nice large size. I poured in a whole gallon of distilled water and there was still room left in the reservoir.* The water reservoir comes out completely for cleaning and has a handle for easy carrying.* The controls are simple, including both cool and warm mist options, a timer, a sleep function, and several options for rate.* The smart app is convenient if you want to control multiple units in various parts of the house, and there is a scheduling feature.* There are two adjustable nozzles.* Nice, quiet operation.CONS:* I chose this model pver some others for its built-in hygrometer, but it’s highly inaccurate. I tested it against three other hygrometers, moving them every 15 minutes for an hour. All three read 35–36%, while this unit showed 59%. Even without these visual comparisons, the air didn’t feel even close to as humid as the reading suggested.* Since I have other hygrometers, the built-in one doesn't need to be precise. However, without it, the app is useful only as a remote control. The app tracks humidity over time, but its reports are meaningless without accurate readings from the machine.* There is a little side door with a pad for essential oils, but I'm not sure much, if any, of the EOs get into the mist. I couldn't smell them at all.

Great product. It’s so helpful to connect to the app and check water levels and stats on your phone! Easy to clean. No complaints.

I love this one! I have purchased a few in the past, this one is my favorite. I now have two of them! I love the top loading water feature. It's simple, take the lid off, fill with distilled water and put the lid back on. You can even turn the lights off on it for a restful nights sleep. It's quiet and works very good. Warm or cold humidity...it's great!
