That is a pretty good read to optimize temperature for your home, however I find controlling humidity more troublesome during winter months. I live in Sweden and even with a humidifier rated for my apartment size doesn't make much of a dent against dryness.
I had the same issue for years in the Midwestern US. I wasted a lot of money on the little 1 galon warm and cold mist humidifiers.
You need the type that uses multiple paper wicks (they look like air filters). I have one that uses 4 of these and has 2 big fans. It can burn through 4 gallons a day. It's not quiet but it does work.
And as a bonus you can use tap water without having to worry about limescale (it'll stay in the paper wicks which are replaceable anyway)
Wow, I didn't know humidifiers existed. All my life I've only ever used dehumidifiers, which take water from the air and into their tanks, which you have to replace every once in a while. Having to refill a humidifier with water every few days sounds like a huge hassle. It's probably more humid where I live because I live in a state on the east coast of the US.
