Wife relies heavily on the placebo effect with all kinds of different remedies whenever she gets sick. Humidifiers are one of them, and we've gone through several because they're wrong or they get yucky or the room got "sticky" or whatever - I don't pay attention or get involved typically, if she wants to spend $35 annually on humidifiers that she throws away after failing to understand how they work, that is not a problem I need to insert myself into.
I keep a humidifier in my office. I chose a thing after googling, it has an app, I set it to a level that is ideal for guitars (which is why I have the thing), I clean it a couple of times a month with vinegar, during the winter I'm constantly topping it off, I have a hygrometer on the other side of the room to verify the humidity. It's a whole thing, the mx is a pain in the ass but it works well and my office stays at 45-50% humidity.
Wife has a cold and bought a new humidifier. A 6 liter govee. Uh, ok dude, do you want me to set that up? We probably should've gotten a levoit so I could control it with the same app as the one in my office. "Oh I don't want to do anything that complicated, don't worry about it".
Woke up this morning to a literal cloud in the room, the sensor on the front of the thing is reading 83%. jtfc i just installed the app on my phone and put a password on it, set it to 50. trying to decide if i should tell her it uses invisible mist.
