My levoit oasis mist humidifier works really well in drier months. Too well sometimes

Legit OasisMist works excellently.

Had 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.

Running a humidifier in my room while I sleep helps a ton. I bought [this one](https://a.co/d/fGDFBD5) earlier this year to replace an old one that was harder to clean, and it’s been great so far. You can sync it with an app to set your ideal humidity level, rather than plain on/off. I also keep a saline spray on my bedside table and use that before bed and if I wake in the night. Also drink a lot of water during the day to stay hydrated. I find the nights the dry air is worst for me are the nights I haven’t been drinking enough water. I’m sensitive to the dry air anyway, and I’m pregnant right now so it’s like x100. I hope this helps!

Been 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

I’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.

I recommend Levoit's top-filling models instead. They're not at Costco, but they work great, are much easier to fill and clean than bottom filling ones, and the brand is pretty solid. Just make sure to keep up with cleaning, ultrasonic humidifiers require it or they get nasty. I clean with both vinegar and bleach (separately, of course) and mine have been working for years.

I 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.
