Seconding this one. I find it very easy to fill and clean (relatively, there are still some crannies). On high, it can last 12 or so hours and works wonders for me in the winter.

been running a levoit classic 300s for about a year now and it's solid. integrates well with ha and the tank size means i'm not constantly refilling it. avoid the xiaomi ones unless you enjoy fighting with connectivity issues every other week.

A whole home humidor is the best investment.  We have a Levoit cool mist in addition to whole home. I think it’s the 300S

We love our Levoit.  Using distilled water helps

You should use a cool mist humidifier for baby. We have a levoit and like to a lot. It has an auto shut off feature which is nice.  If the air is too dry in the whole house you may want to consider a whole home humidifier

You should use a cool mist humidifier. We have a Levoit that works well. But we use it in addition to our whole house humidifier we recently had installed. The whole home humidifier was an investment but worth it

Thanks for the response, but I just bought the Levoit classic 300S off Amazon. I tried using the spreadsheet that was on the sub, but it was too difficult on the phone. Hopefully this one wil be good enough.

I’ve had my [Levoit Classic 300S](https://www.reddit.com/user/Royeth_Ones/comments/1of6v47/best_humidifiers_ive_actually_found_worth_buying/) for over a year now, 6 L tank, runs for \~60 hours, Alexa control, super quiet, and it’s been rock solid. I refill it weekly, descale monthly.

For small to medium spaces, [Leviot 300s](https://us.vesync.com/product-detail/levoit-classic-300s-smart-humidifier-17) is nice. Very quiet, doesnt cause leakage etc. Havent had any issues with mold. It is ultrasonic, and starts up very quick. i swith between tap water and distilled water. The white residue will be there if you use tap water in the evaporative ones.

Levoit 300s. Own one for a couple years now and works great. Mostly use distilled water, but would occasionally use tap water too. App features are nice too for timed runs etc. No need for cleanup or any residue/mold buildups

My water is classified as "hard". I have a nice humidifier I always use distilled water in. I stumbled on some levoit 300?s a few years ago for next to nothing and decided to just run tap water since I had replacements. I'm always surprised when I take it apart for it's annual cleaning how clean it is.
