I 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.

I 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.

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.

2 months ago

I bought a Canopy, without realizing how gamed the marketing is in this sector. It was essentially a paper filter tower dipped in a reservior of water with a computer fan drawing air through the filter. It worked, but the construction was dead simple for being over $200. And required a new filter every few weeks. And of course, it had a noticeable cooling effect. Then, I bought a Levoit with warm mist option. It had a design flaw where it was very easy to water log the boiler, which caused flooding. I then tried a Dreo and so far so good. It also has a heat option.

YES! We just bought a Levoit with both warm and cool air options. So we run a dehumidifier in the summer, and a humidifier in the winter. Plus a couple of air purifiers. So glad we switched to solar panels.

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.
