1. Eliminate Clutter

Cast a critical eye on household clutter, and pare down your stuff. Clutter blocks airflow and prevents your HVAC system from circulating air. Furniture and draperies that block supply grilles cause condensation. All this moisture creates microclimates in your home that welcome and feed mold growth.

So throw out things you don’t love or don’t use. Push furniture away from vents and grilles to keep air circulating. On humid, still days, run a couple of fans to keep air moving.
