DampRid vs. Dehumidifier: Battle of the Humidity Busters for Your RV

Maintaining the right humidity levels inside your RV is crucial for comfort and preventing moisture-related issues like mold and mildew. When it comes to reducing humidity, two popular options are DampRid and dehumidifiers. In this article, we will compare DampRid and dehumidifiers to help you choose the best solution for keeping humidity in check inside your RV.

Understanding Humidity Control

Before diving into the comparison, it’s essential to understand the basics of humidity control in an RV:

  1. Relative Humidity (RH): RH is the percentage of moisture in the air compared to the maximum amount it can hold at a given temperature. Ideal indoor RH for an RV is typically around 30-50% to prevent moisture-related issues.
  2. Causes of High Humidity: RVs can experience high humidity due to cooking, showering, and even breathing. In colder weather, condensation can occur on windows and surfaces.
  3. Consequences of High Humidity: Excess humidity can lead to mold growth, musty odors, and damage to wood and upholstery.

DampRid: The Moisture Absorber

DampRid is a moisture-absorbing product designed to pull excess humidity from the air. It comes in various forms, including hanging bags, tubs, and refillable containers. Here are some key points about DampRid:

  • Passive Solution: DampRid operates passively, meaning it doesn’t require electricity. It’s a silent and energy-efficient option.
  • Placement: You place DampRid containers in areas prone to high humidity, like closets, bathrooms, or cabinets.
  • Maintenance: DampRid needs periodic replacement or refilling as it absorbs moisture. The frequency depends on the humidity level in your RV.
  • Effectiveness: DampRid is effective at reducing humidity in small, confined spaces. It’s an affordable and low-maintenance solution.

Dehumidifier: The Active Moisture Fighter

A dehumidifier is an active appliance designed to remove excess moisture from the air. It operates by drawing in moist air, cooling it to condense the moisture, and then expelling dry air. Here are some key points about dehumidifiers:

  • Active Operation: Dehumidifiers require electricity to operate. They have a fan and compressor to actively remove moisture from the air.
  • Coverage: Dehumidifiers are effective at controlling humidity in larger areas, making them suitable for RVs with multiple rooms or open floor plans.
  • Continuous Operation: Dehumidifiers can run continuously, automatically maintaining the desired humidity level.
  • Maintenance: Dehumidifiers require periodic cleaning and filter replacement. Some units have a drainage hose for continuous drainage.

Comparing DampRid and Dehumidifiers

Let’s compare DampRid and dehumidifiers based on key factors:

  1. Cost: DampRid is typically more affordable upfront, while dehumidifiers have a higher initial cost.
  2. Coverage: Dehumidifiers can cover larger areas effectively, making them suitable for bigger RVs or for comprehensive humidity control.
  3. Efficiency: Dehumidifiers actively remove moisture and can maintain specific humidity levels, while DampRid is passive and depends on the environment.
  4. Maintenance: DampRid requires periodic replacement or refilling, while dehumidifiers need filter changes and occasional cleaning.
  5. Electricity: DampRid does not require electricity, making it energy-efficient. Dehumidifiers consume electricity, which may be a concern if you have limited power sources.
  6. Portability: DampRid containers are easy to move around, while dehumidifiers can be bulkier and less portable.


The choice between DampRid and a dehumidifier for reducing humidity in your RV depends on your specific needs and preferences. DampRid is a cost-effective, passive solution suitable for smaller spaces and those with limited power sources. Dehumidifiers, on the other hand, offer active, precise humidity control and are ideal for larger RVs or those with more extensive humidity issues.

Consider the size of your RV, your budget, and your humidity control requirements when making your decision. Whichever option you choose, maintaining the right humidity levels in your RV is essential for comfort and the longevity of your mobile home.
