LEVOIT Humidifiers 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

Excellent little humidifer. I don't use the app, so maybe that's not very good, but i don't have to use the app as it works great by itself. The tub on top is easy to remove, carry, fill, and reinsert without spilling a drop of water. The buttons are all easy and useful and the humidity indicator is very intuitive.The ONLY problem i could possibly have with this product is that the 'auto' feature, if you turn the humidifier off with it enabled, will spew mist for about a minute when turning it back on, even if humidity is higher than the max. The indicator said 80% and it still spewed mist after turning it on.It's also virtually silent, if it makes any noise it blends into the background and is perfect white noise to sleep.I am almost angry this company doesn't make dehumidifiers cause i'm sure they would be just as good.

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!

Levoit Humidifier ReviewI absolutely love my Levoit humidifier! From the moment I set it up, I found it incredibly easy to use, and the app integration is a game changer. Being able to control the humidifier directly from my phone adds a level of convenience that I didn't know I needed.The app provides real-time information on the humidity levels in my home, allowing me to make adjustments on the fly. This feature has been particularly helpful in maintaining a comfortable environment, especially during dry seasons.Overall, the Levoit humidifier has exceeded my expectations with its ease of use, smart technology, and effective performance. I highly recommend it to anyone looking to improve their indoor air quality!

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.

I struggled with sinus issues all of my life. At night I haven't been able to sleep due to congestion. I purchased this humidifier and have been breathing nightly with no problem. It's easy to clean, small, and powerful. I love that it's so quiet. I definitely recommend.

Why did you pick this product vs others?:So easy to clean! The app is great at setting a humidity level and reminding you when the device needs to be cleaned!

This works great. Does a great job humidifying a large size room. Stonger than expected. Very easy to fill with water. Very easy to clean. Extremely quiet. The app function is easy to use and a great addition. Warm and cold mist function are a great option.
