Yup. Pretty much the same. There is almost nothing to be done about sealing windows and whatnot (they are actually sealed very, very well but the point is I cannot modify the building).
There is a second transitory factor I did not mention.
If your residence has had low humidity for months and months and maybe years and years, all the drywall and furniture are themselves desiccated. And as they’re exposed to more humid air, they will try to absorb that moisture to reach equilibrium. Same is true for wooden flooring, cabinets, clothing, etc. Anything not made of stone or plastic is absorbtive and will pull newly induced humidity out of the air and into themselves.
With the result that you’ll be pouring gallons of water into them all until they reach your desired more humid equilibrium. You might need X/gallons per day of humidifying capacity to get to your target value any time this year, but once arriving there, be able to maintain that target value on maybe 80% of X gallons per day.
The tighter your envelope, the larger the relative contribution of one-time re-humidifying your contents. With a leaky envelope, you’re mostly actually trying to re-humidify the outdoors. Which task is so immense as to be immovable.
I have both an AC that functions as a dehumidifier, and also a device that removes moisture and releases heat in doing so. Just as there are a variety of types of humidifiers, there are a variety of types of dehumidifiers.
