"They work great without additives. ... I never use any in mine."
"It’s basically a humidifier that also ‘washes’ the air, it traps a lot of dust an fine particles, without the use of filters (which is nice, because replacing them sucks)."

I can't sing the praises of my [Venta](https://www.venta-air.com/en_us/product/lw45-comfort-plus-humidifier/) highly enough. I moved from a house with integrated humidity control to one without, and it was a constant struggle. I started off with multiple ultrasonics around the house: white mist everywhere, constant 'clean the gunk out' of the larger reservoired units, and still had trouble keeping the place above 25% humidity. I switched to evaporative because I didn't like the dust everywhere and replacing the wicks was marginally less disgusting, and significantly less work, but man it was noisy. And those wicks aren't inexpensive, and crust up fast. The house had gotten down to 12% humidity one year, and the baluster cracking right next to me sounded like a rifle shot. That was when I started looking for other alternatives while saving up for the integrated solution, and found the Venta. Evaporative humidification, no wicks to constantly change, hUge reservoir, and much less noisy (comparatively quiet even!). Additional bonus: due to how it pulls air through the water to humidify it, a certain amount of dust/particulate matter is removed into the bottom of the reservoir. They used to call these things "air washers", but that was a stretch. It's by no means any sort of 'air filter', but it's not *nothing*. I got the LW45 Comfort Plus model (automatic fan speed control based on target humidity setting), and plunked it down in the most central spot of my split level. In concert with the HVAC helping recirculate things, even though the unit is rated for 645 sq ft, it took the humidity from 12% to 20% in a couple of days, and by the end of the 2nd week we were up to 30%. My house has central heating, and this was during a Wisconsin single digit cold stretch. There's an every-couple-of-weeks additive that keeps things from growing in the water, and an 'end-of-season' final wash-out cleaner, but that's it from a maintenance perspective. I noticed the levels in the house were getting down to the mid 20s, so it's time to bring it back out and set it up, again. Oh! It's been working so well for us, we haven't bothered continuing to consider the integrated solution.
I use this one currently https://www.venta-air.jp/products/#originalconnect I was impressed of the chemicals you can buy with it, all the residue is left in the water and a simple rinse will be enough maintenance. The ones that steam the air for example, there will be a ton of calcium buildup in the meshes that wick up the water to be heated up and evaporated. I've tried many, the piezoelectric ones (those that op talks about) are the worst.
Venta branded humidifiers are great
I went through this exact same obsession last winter when my bedroom was hitting like 18% humidity, felt like I was living in the sahara desert. Ended up going with a Venta after reading through probably 50 forum posts and I'm pretty happy with it - thing's been running daily for about 8 months now with zero issues. The maintainence is actually pretty minimal despite what some people say, just rinse the discs every couple weeks and change the water regularly. Only downside is it's not the fastest at humidifying but for your size room it should handle it fine, plus it's whisper quiet which was huge for me since I'm a light sleeper. The build quality feels solid too, like it could run for years without breaking down
I have one. Haven’t needed service so no idea about the customer support. I’m not sure the Venta formula cost is cheap enough to offset the cost for physical wicks, but otherwise it’s fine.
Look up the venta humidifier. It spins a plastic cylinder of disks slowly and blows air over it. I got mine shipped from home depot but Amazon has them too. Get that and a bottle of steramine tablets. Put a half in once a month or two when you clean it. It won't get nasty, you don't need to replace any paper filters, it doesn't get mildew or messy gross like ultrasonic. And seems well built enough to actually be bifl.
This is discussed often on here. Add the Venta to your list. Expensive initially but no paper filters to replace and it's fully cleanable, unlike any of the mist humidifiers that build up gunk where you can't get at it, seals disintegrate etc. protip: look into stearamine tablets for the paper or venta humidifier. WIth a monthly or so cleaning, and a half to full tablet added each cleaning, I don't get Any slime buildup ever. Cheap too.
Get a Venta Humidifier, it's uses evaporation instead of the usual ultrasonic humidifier (which can be harmful). It's pricier but way easier to clean and maintain and last a long time.
I use a Venta and I’m happy with it. Yes it’s marketed as an air purifier, but I have a coway air purifier that I run all the time anyway.
I’ve had mine for five years and can attest. I rolled my eyes when my husband bought it, but that shit *works.*
Had mine for like 3 years now and honestly the customer service thing is real - took forever to get replacement discs and they were kinda rude about it. The humidifier itself works great but if you're the type who needs hand-holding when stuff breaks, maybe skip it. Your staticy cat will definitely appreciate any decent humidifier tho lol
