Controlling High Humidity Inside your RV

Managing high humidity in an RV is crucial for maintaining a comfortable living environment and for preventing mold, mildew, and other moisture-related problems. Here are some strategies to manage and reduce humidity levels in your RV:

Ventilation

Roof Vents

Make sure to open roof vents, especially after cooking or taking a shower. If possible, install vent fans to help circulate air.

Windows

On cooler days, open windows to allow for cross-ventilation. This can help displace humid air with drier outside air.

Use a Dehumidifier

Invest in a quality dehumidifier suitable for the size of your RV. Empty its water tank regularly.

Air Conditioning

An air conditioner not only cools the air but also reduces its moisture content. Ensure your AC's filters are clean for optimal performance.

Cook Outside

Cooking can introduce a lot of moisture into the air. Whenever possible, consider cooking outside.

Limit Indoor Plants

Plants release moisture into the air. While a few indoor plants might not significantly raise humidity levels, having many could contribute to higher humidity.

Monitor Humidity Levels

Purchase a hygrometer to monitor indoor humidity levels. Ideally, keep the humidity below 60%.

Avoid Hanging Wet Clothes Inside

If you need to dry clothes, try to do it outside. Wet clothes release moisture into the air as they dry.

Improve Insulation

Ensure doors and windows are sealed properly to prevent humid outdoor air from seeping in. Check weather stripping and replace it if it's worn out.

Bathroom and Kitchen Fans

Always use exhaust fans when showering or cooking to vent out the moist air.

Moisture Absorbers

Consider placing moisture absorbers or desiccants, like silica gel or DampRid, in areas prone to dampness. These products absorb excess moisture from the air.

Avoid Propane Heaters

Propane heaters can release a lot of moisture when they burn. If you're using them for heat, ensure good ventilation.

Regular Maintenance

Check for leaks regularly. Water infiltration is a common cause of high humidity in RVs. Ensure all seals, windows, and roof areas are watertight.

Limit Shower Time

Long hot showers can significantly increase humidity. If you don’t have adequate ventilation in the bathroom, consider taking shorter showers or using campground facilities.

Park Wisely

When setting up camp, consider positioning your RV in areas with good sunlight and airflow. This can help reduce condensation and dampness around your RV.

Summary 

By implementing these strategies, you can significantly reduce humidity in your RV, ensuring a more comfortable environment and preventing potential moisture damage.
