LEVOIT OasisMist Smart Cool and Warm Mist Humidifiers for Bedroom Large Room Home, Auto Customized Humidity, Ultrasonic Top Fill Oil Diffuser for Baby and Plants, Quiet, 4.5L, White

Does it’s job but a bit of a pain to clean. I run it almost constantly during fall and winter. Needs a deep vinegar cleaning almost weekly even when using purified water. Otherwise no complaints.

With the dry winter air in the bedroom overnight, my cats chronic rhinitis was flaring up -- he sometimes sneezes 8 or 10 times in a row and his eyes look sore. I set this up on a bedside table -- it is so quiet -- and it runs all night on a gallon of distilled water (cool mist). In one week, his congestion has improved, few sneezes and little eye discharge. He sleeps on the side of the bed where the mist descends. Also, he can be a picky eater: stuffy nose, impaired smelling ability, loss of appetite. His appetite has improved. Happier cat for sure. UPDATE: 2 months later. I switched to Brita-filtered water without any problem so far, because buying 7 or more gallons of distilled water per week is too costly. Use distilled white vinegar to rinse and wipe out tank and base once per week. ALSO, this is not top-loading. You do not bring the water to the humidifier. Instead, you remove the tank, flip it over onto a flat surface, remove (and replace) a large cap, pour in water, flip it back over, and set it back on the base. This is easy for me to do, but a gallon of water is heavy and any person with arm/hand strength issues may have a hard time. STILL, my cat and I are free of the usual winter allergy-noses and the machine works very well, shutting itself off when the desired humidity is reached.

This is the best one by far. I have severe allergies and this has helped immensely with them especially at night when i go to sleep.

My biggest thing is noise level and I have to say this thing is super quiet. Like the large water container that is easy to remove and clean. Over all I am impressed with this buy.

Ill start of with it IS VERY quiet. You DO get a slight boiling sound on warm mist, but its not bothersome. That being said, lets move on. Received it at 7pm, had it running by 7:30pm. BY 6 AM the water level was low. It would probably have lasted until 7:30 or 8am, giving it around 12 hours (cool mist) run time on high before needing a refill. Now it was on high all night (cool mist), which brings me to my only REAL complaint. You cant preset the level for automatic. Its either 60% or nothing. Has a big beautiful number on the front to display the humidity in close proximity, but you cant set it to a specific level to turn off at. It LOOKS like you can use your phone with an app to set it, but NO. About the only thing the app does if this is all you have is collect a bunch of info IT DOESNT NEED to do the job. It will show you the humidity level on your phone, but if youre anywhere in the room the display is quite large and easily to read, making the app nothing more than another way to get spam. (oh that tasty spam) IF you could PRESET the output % for automatic, this would be a solid 5 star, as it puts out a nice stream of mist, and is VERY quiet. And honestly, it would probably only add a few pennies to the cost to do this... OPERATION: 3 mist levels and 3 heat levels can be set. Putting it in night mode >appears< to turn off the warm mist (removing the boiling sound), along with the display. Even on low mist level it puts out a fair amount, and high you almost have a fog machine, making it great for larger areas like the living room. It has an auto setting, but as stated before it will only maintain the humidity at 60% Overall, it works quite well, and is quiet enough that youll barely notice it running even in a very quiet room (even on warm mist). Good value, but would be a PERFECT value if you could set the level!!
