What’s the difference between an RV dehumidifier and a regular (non-RV) dehumidifier?
An RV dehumidifier is the same appliance you use in your home — simply described, it pulls excessive moisture from the air. A dehumidifier works by drawing air into and over internal coils on which moisture condenses (changes from a gas to a liquid) and is collected in a tank.
A fan blows the remaining drier, cooler air back into the room.
The main difference you’ll find in RV dehumidifiers is the size, as few RVs are large enough to warrant a full-size unit.
Manufacturers make small dehumidifiers ideal for RV use, so you can find the perfect size to keep your RV comfortable.
Common Reasons You Need an RV Dehumidifier
- All RVs have relatively thin walls and inadequate insulation, which results in a lack of sufficient climate control. When the RV interior gets cool, but you’re parked in a humid region, the moisture levels in the air can condense and cause wet, drippy windows, walls, and ceilings.
- When you don’t open windows or run fans in the RV, just the occupants’ breathing can also cause condensation build-up.
- Running a propane heating system also adds a large amount of humidity to the RV.
- RVs are prone to quick mold and mildew growth, especially when camping in warm regions, so keeping humidity levels low can prevent issues.
- Showering in an RV is another reason moisture builds, as many bathroom exhaust fans are weak, and the entire space is cramped, so the shower is typically only a few feet from the living areas.
- Allergens, like dust mites, need at least 65-percent humidity to live, so keeping moisture levels under this number can alleviate irritation.
Common Benefits for Using an RV Dehumidifier
The main reason to use an RV dehumidifier is to stop having to continually wipe up the annoying condensation issue caused by camping in humid regions, running a propane heater, human breath that isn’t getting dispersed, or running showers.
If you leave high humidity inside an RV unchecked, mold will grow fast, and all the water will soak up into the furniture, walls, flooring, and ceiling. Musty smells will permeate the RV, and swelling or popping of walls or flooring can happen. Repairs to fix moisture damage is timely and expensive.
For people suffering from allergies, keeping mold, fungi, mites, and other irritants that thrive in humid conditions from taking over the RV will keep the air fresher and reduce sneezing or runny eyes and noses.
Lower humidity helps people with asthma breathe easier.
A relative humidity level between 30-50 percent is the most comfortable for humans. A dehumidifier lowers humidity to comfortable levels, so you don’t feel muggy or sticky inside the RV.
