The basement carpet had that stubborn musty smell no matter how often I vacuumed. I finally tackled it by ripping up a corner, finding the moisture source from a slow pipe leak, drying everything thoroughly, and applying an enzyme cleaner. A dehumidifier running daily made the biggest difference. Now the room actually smells fresh instead of like an old cellar.
