Dehumidification

If air movers are the accelerator on a drying job, dehumidifiers are the drain. Evaporation only continues while the surrounding air can accept more moisture, so without dehumidification the room air saturates and the drying stalls, with the added water condensing on whatever surface in the house happens to be coolest. That is how one wet room becomes several damp ones.

Two technologies do the job. Refrigerant machines pull room air over a cold coil, condense water out of it, and return warm dry air to the space. Low grain refrigerant units add a pre-cooling stage so they keep extracting water even after the air has become fairly dry, which matters because the last stage of drying is the slow one. Desiccant machines pass air over a moisture-adsorbing wheel instead, reaching lower humidity than refrigerant units and making them the tool for hardwood, plaster, masonry, and large commercial spaces.

Household air conditioning is not a substitute. It cools and incidentally dehumidifies, and in a South Florida summer it spends much of its capacity on outdoor air infiltrating every time a door opens. A dedicated dehumidifier removes far more water per day, discharges dry air back into the space, and can be metered so you know it is working.
