We have a Levoit one that can be controlled by an app. Totally not necessary but it’s really nice to have. Since it’s winter, I now use it nightly for my six month old since he started getting a split bloody lip after naps. I had really bad anxiety that was brought on by his four month sleep regression so I was thankful that past me spent the money on one that we can program. https://a.co/d/0brhzvkp

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.

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.
