@Keith THose AirCare look to be good machines. I’m looking at perhaps getting the bigger whole house one. We bought one of the new AC Infinity ones for our bedroom. We got the little T3 and it works great!, as long as you have pure, RO water to fill it with. Then there aren’t any ‘white powder’ issues. That comes from running city water through the ultrasonic ones. Here is the link, https://acinfinity.com/humidifiers/
I love how it works, hate having to add water 3 times a day (on high). It holds 4.5 liters and will go 10 hours on high, full mist, but is only good for a single room. House RH is about 33-35%. It will keep the bedroom at 40-45% with the door open and I have it set to shut off at 45% RH.
If I go for the whole house AirCare, it holds 6 gallons, https://www.amazon.com/AIRCARE-831000-Space-Saver-Evaporative-Humidifier/dp/B00WAC9VKQ?ref_=ast_sto_dp
That’s way more water than I want to try to get from our RO system, so I would need to replace the wick regularly, as the city water here is extreemly hard and calcified.
Here is my best tip, get it from Amazon, so if you don’t like it, it an EZ return.
