Thanks for all the suggestions! I ended up going with a Honeywell HCM350B, hooked up to an Aeotec smart switch (probably overkill, but reliable). https://www.amazon.com/dp/B00FJTVHKO It's hard to compare the last 48 hours with the previous few days as the temperatures are wildly different (like 30 degrees F warmer), but it does make a huge difference in my 20 foot by 20 foot room. In the last week, the humidity range was between ~17% and ~27%. Since the humidifier it's been ~26% - 43%.

This is what I use currently and within your budget. Tap water safe and easiest cleaning I’ve found so far - not non existent but much easier than others. I also buy a generic filter every 30 days and replace it so be aware that’s an added cost . https://a.co/d/dWKQPhI That said I’m thinking of trying the Levoit 6000s 2.0 as I’m tired of filling up everyday and rotating the filter for two of them (one in each bedroom).

No. they all suck and it is frustrating. An ideal situation is to have a whole home humidifier and just have to keep ontop of one filter and cleaning but of course not everyone can do that (and those have their issue too). I'm also a busy working parent and just decided to try going without a humidifier this year and see how it goes. Try to see how they do. In the past, i've utilized the Honeywell HCM350 and run what parts i can through the dishwasher and clean the rest as best as i can as often as i can (prob every 2-3 weeks realistically). I keep eying the Levoit 6000s but i don't have a spacious place and don't have excess funds at the moment or the capacity to try something and deal with returning it, etc. all this to say, as a parent, you are not alone, it is super frustrating and i wish there was an easy to use humidifer for our little kiddos. I grew up with sinus issues and at this point in my life, i feel like i've tried so many humidifiers and am just tired of it.

I have a Honeywell HCM 350, which is great; you just have to commit to replacing the filters. It's the same model Bin Diving recommends: [https://bindiving.com/results/ew8KGfre](https://bindiving.com/results/ew8KGfre)

There are three fan speeds on mine, I don’t think it’s noisy, but I enjoy some white noise

Yes I could not live without one. I have several. Look at the Honeywell website, they make decent humidifiers. The HCM350W ia great.

I also live in WI. Do not buy any ultrasonic humidifier. What you need is a wicking humidifier like the honeywell HCM350. Easy to clean. Don't need distilled water

Been happy with our Honeywell evaporative humidifier. I’m not sure the model exactly as it’s older but the HCM350 seems to be at least very similar if not the same
