I live in Colorado and had the smaller one you linked but it emptied way too fast. I would have to refill it at least once a day. I use this one now and love it!

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

been using the levoit 300s for like 2 years now and it's been solid, easy to clean and works fine with tap water but you'll need to descale it more often

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.
