Ideal Basement Humidity In Summer

Ideal Basement Humidity in Summer

The ideal basement humidity level in summer is between 30% and 50%. Humidity levels below 30% can cause dry air, which can irritate skin, eyes, and throats. Humidity levels above 50% can promote mold growth and cause condensation on walls and ceilings.

Maintaining the ideal basement humidity level in summer can be a challenge, as the air outside is often humid and the air inside your basement is often cool and dry. However, there are a few things you can do to keep your basement humidity levels in check:

Run a dehumidifier. A dehumidifier removes moisture from the air, which can help to lower humidity levels in your basement. Choose a dehumidifier that is sized for the square footage of your basement.
Use an air conditioner. An air conditioner can help to cool and dehumidify the air in your basement. Set the air conditioner to a temperature that is comfortable for you, and make sure to keep the doors and windows closed when the air conditioner is running.
Ventilate your basement. Opening windows and doors can help to ventilate your basement and remove humid air. However, avoid ventilating your basement when the outdoor air is humid.
Seal air leaks. Air leaks can allow humid air to enter your basement. Seal any cracks or gaps around windows, doors, and pipes with caulk or weatherstripping.
Use a moisture barrier. A moisture barrier can help to prevent moisture from entering your basement through the walls or floor. Install a moisture barrier on the walls and floor of your basement.

By following these tips, you can help to maintain the ideal basement humidity level in summer and prevent problems caused by high humidity.
