"It's MUCH easier to clean non stick surfaces (1 minute after each use). ... Takes me 1 minute to clean my Cosori with a nylon brush and Dawn."
"Clean up is a snap all it takes is a little bit of your dish detergent I use Dawn and three tablespoons of baking soda made into a small little paste you cover the inside you cover the. Inside in the rack with it you wait 15 minutes rinse it well with warm water paper towel dry it and it's done."
"Bacon (easy to clean up afterward, bacon comes out perfect.) ... Bacons great because I don't have to clean a bunch of grease off the stove after. Tip: put a slice of bread on the bottom to absorb a lot of the great, that way its even easier to clean at the end."

"never deflates"
"Also pitched it on bare rock using rocks to hold the stakes on a decently breezy night and it was pretty bombproof."

"The cats are finally not terrified of it ... I can set it to quiet mode where it is barely audible ... Even quiet mode picks everything up just fine."
"I have that unit and absolutely love it for its cooling power to noise output."
"Die midea hat aber einen Inverter und der ist viel leiser als der herkömmliche Kompressor in Monoblock Geräten. ... während du neben der midea schlafen kannst"

"For us in our room, we have a Leviot cool and warm mist humidifier that automatically adjust to the air…10/10."
"My little tanks work great and are very effective ... Mine got up to 50% humidity within a few hours."
"It’s super quiet with an adjustable knob for humidity levels."

"I have the Bluetooth/app enabled one in my daughter’s room so that I can set a humidity level and run it on auto. ... And if needed I can shut it off or turn it on in her room without going in at night."
"I like having the option to set the times it runs and the target humidity level"
"I only like the HP02 since it has app control. Anything after HP02 they don’t let you control the heat with the app which sucks"

"My small Levoit basically does nothing to change the whole home humidity."
"I bought a Levoit LV600HH (a hybrid ultrasonic/evaporative, apparently) a couple years ago and found that it didn't change the humidity of the room much at all"
"Lately at night the humidity in my bedroom is 20-25% with my Levoit humidifier next to my bed."

"Unfortunately did not install mine until after the Amazon return window ended and I had collapsed the box. I had emails with them back and forth about the smell, assuming that it was covered under the warranty. They were not very helpful. In fact they were very dismissive and told me to get someone to clean it (almost as expensive as the air conditioner) or clean it myself (which I believe would void the warranty) so I used the wick trick to drain water from the a/c and purchased an extended warranty. ... I don't understand why they would have created an AC that didn't drain. ... My brother has two of them, one of which is full of mold"
"it got full of mold in 6 months ... I tried to remove the casing to clean the mold but it’s just in a really inaccessible spot deep in the cold air vent."
"No mold in tricky spots (yet anyway)"

"A note of caution: ultrasonic humidifiers like this atomize *everything* in the water, including any bacteria and minerals. The droplets are microscopic (in the nanometer(!) range), and so can penetrate deep into your lungs. If you're using an ultrasonic mister, you should be using distilled water, or, ideally, deionized. They recommend washing it every few days too. (Most of the parts can go in the dishwasher.) And don't leave water in the mister reservoir when you're not using it. ... As an example of how they can vaporize (bad) stuff other than water, when I first filled the Levoit mister, I poured in water from a gallon jug of distilled water that I had, but I forgot that I had added table salt to the water for flushing out my sinuses. The water was as salty as seawater, and the mist it made created a white fog in the room that left a white deposit on tables and the stereo and everyplace where it landed. Breathing sodium chloride probably isn't too bad for you, but if you are seeing "white dust" after adding hard water, you are probably breathing calcium sulfate deep into your lungs, and that is probably not good at all. RTFM and follow the instructions! ... Bacteria and minerals, both, and the microscopic droplets carry both deep into your lungs."
"The carepod doesn’t have a filter need, but it requires distilled water, and I cannot stand the idea of buying water and using over 1 gallon of it per day. ... We returned the carepod. It was too expensive for me to comfortably use tap water and our cheaper humidifier from before either of these two left white dust everywhere when we used tap water."
"However, the distilled water that I'm using in my Levoit mister requires is $2.50 a gallon, and I use about a gallon a day, so the Vicks is cheaper (to say nothing of the inconvenience of hauling about 50 pounds of distilled water home from the grocery store every week). ... I'm putting distilled water in this ultrasonic mister now, and at about a gallon a day, the cost kind of adds up, and more importantly, having to buy and haul in multiple 20-pound plastic jugs to feed the thing every week is kind of a pain."

"Yeah, I have 6L Levoit and it's a pain in the ass to clean. I do it once a week."
"its filter was always damp and would get moldy if I didn’t replace it fast enough"

"Our Levoit was a headache the whole time between frequent cleaning"
Next-Ad3196 1.0I just bought this [expensive humidifier](https://a.co/d/ebxf3yx) for the house but for right now I’m keeping it by my orchids. It tells me the humidity in the house and I have all the capabilities to control the mist strength and how high I want the humidity etc. There’s also a plant feature which tells you what the ideal humidity for your plants need to be. I have a preschooler and with back to school and cold and flu season on the horizon I justified this purchase.
nxlinc 1.0I have a Levoit OasisMist 4.5L humidifier next to my bed. I got an open box deal on Amazon for like $40. It's hard to keep a whole living space humid, so I focus on the bedroom. I also recommend using distilled water since the tap water here has so many minerals. I bought a 1gal water distiller on Amazon to make my own.
Paul_Deemer 1.0I have both the Levoit OasisMist 450S which is 4.5 liters and the Levoit Oasismist 600S which is 6 liters. I use distilled water in them and clean them every both every Sunday. They are always clean looking because I use distilled water. When cleaning I remove all the little parts and soak them in a White Vinegar solution of 1 part white vinegar to 1 part water for about 30 min. I also swish the mixture around in the tank and then I pour it out and let everything dry. Then fill it back up with Distilled Water and good to go for another week. You could probably get by doing it every two weeks because with distilled you don't have a bunch of minerals depositing in the bottom of the humidifier which makes it orange and nasty and yes hard to clean.
bean_martin 0.4Legit OasisMist works excellently.
hartofalyon 0.4Had a few LEVOIT OasisMist that worked pretty well. The warm mist feature is nice, but had to constantly get distilled water to avoid white mineral dust covering everything as it's ultrasonic. This year, just picked up LEVOIT Sprout as it's evaporative so can use tap water. Most evaporative models I've researched have mold problems, specifically in the unserviceable fan assembly as their designs have the fan after the wick, pulling moist air through. Sprout's design has the fan *before* the wick so it *pushes* the moist air out instead. So far so good.
PEM_0528 0.2We have a cool mist humidifier in our daughter’s room. It definitely makes a difference. My recommendation, get one you can clean easily and that you can use essential oils in. The brand we have for her is Levoit, can be bought on amazon. We previously had the Fridababy one and it was a pain to clean so I wouldn’t recommend that one. For us in our room, we have a Leviot cool and warm mist humidifier that automatically adjust to the air…10/10. We only use purified water in our humidifiers.

even_spite_0809 0.1I have a Levoit top fill humidifier. It’s super quiet with an adjustable knob for humidity levels. I used the filtered water on my fridge (personal preference) but think it would be fairly easy to clean periodically if tap water was used.
Individual-Class-578 0.1Been using a Levoit for about 2 years now and it's solid, just don't slack on the weekly cleaning or you'll regret it lol. The top-fill design is clutch when you're lazy about refills
k3nzer 0.1I’ve tried multiple and I feel like no matter what they get moldy🥲 best I’ve found is the Vicks 3-in-1, it serves us well when emptied and dried daily, and fully cleaned every few uses. Frida baby 3 in 1 immediately got moldy, as did our levoit top fill. But the ultimate winner is a whole home humidifier. We splurged($1000 for install and humidifier) because we have number 2 coming in August and I despise the upkeep of room humidifiers.
nojustnoperightonout 0.1I just ordered a levoit brand one, having had other levoit ones that last a long time. The difference in the new is it is top fill, and has a big opening, and made specifically for easy cleaning. I will also make it a point to never put tape water in it, distilled only. I used to use the additives that supposedly make it not gunk up, but in the Midwest/Ohio valley area, our water has a lot of dissolved minerals (limestone especially) and is very "green" with lots of living organisms too small to be seen, even when treated.
