Is 50 humidity high outside?
The higher the temperature, the more water vapor the air can hold. The ability of the air to hold water changes as the temperature goes up or down. A humidity level no higher than 50% is optimal as a general rule of thumb, but the best level depends on the temperature outside.
How do I keep mold from growing in my dehumidifier?
Can dehumidifiers cause mold?
A dehumidifier deposits this moisture into a water basket, where it collects. If not emptied regularly, the stagnant water can lead to mold forming on the inside of the collection basket.
Will dehumidifier dry out damp walls?
Dehumidifiers can help remove moisture from the air, which indirectly removes it from the walls, too. To speed up evaporation, remove molding and baseboards to prevent moisture from entering behind them. Store the molding in a dry, safe place to avoid damaging it.
