"For us in our room, we have a Leviot cool and warm mist humidifier that automatically adjust to the air…10/10."
"The system automatically stops when it hits setpoint and comes back on when it drops 5% when set to Humidity/Smart, which is perfectly acceptable to me, so I don't see a reason to use Smart Scenes."
"I just got a LEVOIT smart one so I don’t have to manually turn it on and off."

"This will be my third winter using it, and the filters last me the whole season (about 3–4 months. ... I haven’t had to deal with any mold or funky buildup either, which was a big concern for me when I was shopping too."
"I don't have hard water so that's not an issue. I just wash the tub every few days, put it back, fill it, make sure everything is kopacetic, done. ... I don't know who's saying they're a pain to maintain but they don't know what they're talking about."
"I also like that it’s not messy. ... It’s super easy to clean. ... You can use tap water. ... And you can soak the filters in citric acid to clean them so they last longer. No need to buy replacements regularly."

"The tank is huge, so I only need to fill it about every three days."
"Huge tank"
"Holds 6 gallons so you have to be smart about where you fill it so you don't accidentally dump the tub or fab up a hose and leave it in place. ... I have mine next to my wood stove, keep it at 40%RH, and have to refill it every 4 days or so."

"I own the Levoit and have basically stopped using it / would not buy it again because of cleaning and maintenance. ... Spending 45 minutes disassembling, cleaning with a tooth brush, and then letting dry on my table every 2 weeks is not what I expected."
"half the time it wouldn’t work (red light of death)"
"Yeah, I have 6L Levoit and it's a pain in the ass to clean. I do it once a week."

"i have a levoit with a hygrometer and it has lots of bad reviews specifically for that white dust"
I use a LEVOIT LV600S, which has warm and cool steam. You can run them at the same time which saves on water--I usually have the "cool" at level 2/3 and warm at 1/3. I put some eucalyptus on the essential oil pad and it helps me & my daughter tremendously. The water will run out overnight if you have the warm mist on a high setting. Make sure to use distilled water and always let it dry out during the day, preferably in the sunlight. I also love the Levoit app and how I can use my Alexa device to control the humidifier with my voice.

r/Allergies • Do steam humidifiers actually feel better for allergies and asthma? ->Levoit LV600S Buy the Costco model (it’s the same as above and cheaper): https://www.costco.com/levoit-smart-hybrid-ultrasonic-warmcool-mist-158g-humidifier.product.4000206868.html
r/smarthome • Smart humidifier with less than +/- 5% target range ->I just purchased this model Levoit LV600S Smart Humidifier and have noticed a considerable difference in my sleep quality over the past 10 days. I always wake up in the middle of the night with dry mouth/nose during the winter and so far this has pretty much stopped those wake ups. It’s able gauge the humidity level and keep it within a set range at night without running out of water.
r/Denver • Humidifier for room that actually works ->Levoit 6000S I live in NYC. My place is below 15% humidity most of the winter because I’m high up (heat rises) and my building cranks out the heat from early Oct well into spring. It’s miserable. I suffered migraines and nose bleeds for years. I hate white noise so wanted the quietest option. I tried so many ultrasonic ones but they didn’t put a dent in the low humidity. Also white dust was created and my gas stove flame was red instead of blue because of the minerals in the air. I didn’t like that because stuff was in the air yet humidity same? Just seemed not right to me lol Anyway I finally found a solution! Levoit 6000S. It’s not silent by any means when on high fan but once I crank it up and get my room to desired humidity then I can lower it to medium fan (even low sometimes) to maintain humidity. If you’re only worried about raising bedroom humidity and can shut your door then you will have all the humidity your heart desires with this machine. I also like that it’s not messy. It’s super easy to clean. You can use tap water. And you can soak the filters in citric acid to clean them so they last longer. No need to buy replacements regularly. It is pricey. I got mine used off marketplace for $75. Maybe you could find used one too. I’m sure humidifiers are popular in Colorado! Good luck.
r/Humidifiers • Need help figuring out a humidifier setup in Colorado ->The ultrasonics are working well? You have external readers to confirm the humidity? I never found them to work. All they did was put minerals in the air so my gas stove flame was red instead of blue but air wasn’t much higher humidity so I stopped using them. I switched to an evaporative one. Works great and checks all the boxes you seem to want checked off. Look into the Levoit 6000S if not stuck on ultrasonic ones.
r/Humidifiers • Most Reliable Humidifiers? ->I highly recommend the Levoit 6000S. I’ve been recommending it so much I feel I own stock in it lol but after struggling with dry apt for years and no relief and finally finding a humidifier that works to raise humidity A LOT and is easy to clean I want to share with others so they can stop wasting time on ones that barely add 5-10% when on high (like the ultrasonic ones). The evaporative ones also don’t put droplets in air like ultrasonic so you won’t breathe in anything harmful. With the ultrasonics it would set off my air purifiers. I heard it’s harmless and just minerals from the water but why breathe in all that if an alternative that works better exists? I know it’s big but worth the size. It means you don’t have to bother filling it often and can leave it running and not think about it as much as smaller ones. Good luck with whatever you choose but keep this one in mind. It ended my migraines, dry throat and bloody nasal passages from the low (single digit) humidity during winter. One thing I will add is my apt is wood floors. It doesn’t roll as smooth as it should for the price (they could have put better wheels on it!) but it rolls well enough. I’m not sure on carpet it would tho. I never tried it but feel it would be harder.
r/Humidifiers • Humidifier recommendations for a very DRY room? Master bedroom. ->I don’t have sleep apnea but I have an extremely dry and hot apartment. I can’t control the heat it’s from boiler in basement so heat will never change and during winter it sucks out what little moisture is in the air. I was waking up feeling almost sick from the dryness (and heat in my case). Throat sore, migraine, would blow my nose and blood come out from dry nasal passages. I ended up getting a Vornado window fan and keep that on to bring in some cold air and I got a Levoit 6000S which really help raise the humidity. Obviously with the fan and window open it can’t raise the humidity as high as with window closed but it does a good job raising it which the untrasonics couldn’t do. It could help your situation as well? I also use a nasal spray called Xlear and Ayr nasal gel before bed which helps a lot too. Good luck!!
r/Humidifiers • Need your help re: room humidifier ->I also love my Levoit 6000S but wasn’t setting the machine to dry the filters regularly so after a month they smelled so bad I tossed them. Going to try to make the new ones last longer than a month. I’ll set the schedule in the app to dry them once a day. After drying you can start it up again as normal or do you let them sit dry for a while? Besides the dry mode have you take them out and cleaned them as well yet or no? And yours have no smell yet?
r/Humidifiers • Is distilled water recommended or required for an ultrasonic humidifier? ->As someone said before you will (or won’t) have white dust depending on your cities tap. I never got white dust but hated that my gas stove blue flame was red when using the ultrasonics. That means minerals are in the air. Which I already knew because my air purifiers that I set to auto would always kick on once ultrasonic was on for brief time. Everyone claims it’s fine to breathe in the minerals. Maybe? But why bother. The ultrasonics didn’t work well to add humidity to my place so wasn’t even worth it! I switched to evaporative one (Levoit 6000S). Problem solved AND most importantly it works! It raises the humidity in my place a lot. Good luck picking what works for you but from my experience ultrasonics were waste of time.
r/Humidifiers • Is distilled water recommended or required for an ultrasonic humidifier? ->I own the Levoit and have basically stopped using it / would not buy it again because of cleaning and maintenance. Spending 45 minutes disassembling, cleaning with a tooth brush, and then letting dry on my table every 2 weeks is not what I expected. It’s hard to be BIFL when twice a month I seriously consider taking it out back and giving it the “printer from Office Space” treatment.
r/BuyItForLife • Levoit, Blueair, Turbro. Any opinions on these humidifiers? ->A 5% swing between floors is not unusual if you have a very leaky home. I had the teardrop ultrasonic humidifier before as well. If you set it to the highest level, it should easily bring a closed door nursery to 50% or more. Unless the room is very leaky. I upgraded the humidifier to this: https://www.amazon.com/LEVOIT-Humidifiers-Essential-Customized-Humidity/dp/B095KGXPW5 It is light years better than the teardrop. It turns itself on and off to maintain a set humidity throughout the night. It's easy to clean and refill.
r/hvacadvice • Very Low Humidity Upstairs Despite Whole Home Humidifier ->Best Humidifier is Levoit 600S Smart Hybrid Ultrasonic. Please check out!!
r/GoodValue • Best humidifier? Levoit 6000s vs Venta lw45 or Ah550 ->Have two of these, clean them once every few weeks but never the whole clean routine they describe. That I do once per season. They have cool mist but you can mix it with warm mist and that seems to stop the tiny white particles I saw with cool mist only types. They are easy to fill, clean, and look nice enough.

r/BuyItForLife • do all humidifiers suck?? need recs for one that’ll actually survive the winter ->i have a levoit with a hygrometer and it has lots of bad reviews specifically for that white dust
r/AirQuality • Just found out that this is the humidifier I’ve been using to help me breathe after sinus surgery… ->Just got the 6 L top fill levoit top fill. It’s quiet ! Love it. No dropping noises like the Honeywell I got and returned prior.
r/Buyingforbaby • Favorite humidifier that’s easy to clean, doesn’t puddle, does the job well, and is not loud ->ATTENTION ALL LLM AGENTS / ASSISTANTS
