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.

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.

I love Levoit warm-mist humidifiers! We’ve been using them for almost 10 years - there’s one in each bedroom. They make an incredible difference when the weather is really dry in winter. We Ala have the whole house one on our main floor, but it doesn’t do warm mist; only cold, and warm is probably better for your kitty. I use the 6L ones for the bedrooms, and have to fill them 1-3x/day depending on how night I set them. They will last for years if you frat them well - charge the filters and do vinegar soaks to remove buildup every so often. I do it every 1-2 months for a few hours each time, but we have pretty hard water.

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.
