Simple activities like breathing, cooking, taking a shower can significantly elevate the moisture levels in our RV which are always small and enclosed. This moisture level is called humidity. It is the amount of water vapor present in the air. Due to the relatively small sizes of our cabins and the myriad of activities that go on in them daily, the water vapor level is always very high and due to the variation in the temperature of the outside environment these water vapor condenses and form water droplets. This water droplets form on windows, doors, tables and on other spots in the cabin causing unpleasant smell and making molds and mildews find such very humid and wet places as safe havens. This starts to cause damage on our utilities, create an unhealthy and discomforting environment, filling the cabin with even stinky and musty smells, especially when your RV toilet is not working well. If not corrected, permanent damage might eventually result, leading to a gross stench and very likely visits from close by pests like termites.
Opening windows and doors to let air out, sleeping with open vents, wiping the wetness off the walls of your home can help with this, but this soon become very inapplicable in extremely cold conditions. Is the inside of your RV a damp disaster full of mold and mildew? One sure way to establish comfort and restore the pristine nature of your motorhome is in the use of Dehumidifiers.
What is a RV dehumidifier and how does it work?
A dehumidifier is a device that reduces the water vapor level of your RV. It is an electronic device that pulls out water from the air while not changing its temperature. Moist air enters the device, the moisture is extracted and collected, and then dry air is expelled to out. When left to run for a period of time, the surrounding will become dry. This totally eliminates the issues of wet walls and windows, insects or any form of moisture damage that might have developed over time. The greater benefit of all is the smell of natural freshness that will be replete in your motorhome giving you the confidence that you are dwelling and travelling in a clean and healthy space.
There are two types of dehumidifiers:
- The desiccant dehumidifier and
- The refrigerant model dehumidifier.
If your cabin is very small or you discovered a localized humidity problem in one corner of your cabin, then the rechargeable dehumidifier is a good choice. It is also the best to use in closed spaces such as in closets. They make less noise than the refrigerant model, are lighter in construction, and operates at temperature levels that are as low as 33 degrees Fahrenheit.
For larger application the refrigerant model is used. They are however very heavy to move, make a lot of noise, have more mechanical parts and do not work very well at temperatures lower than 40 degrees Fahrenheit.\
What should you look out for when scouting for a dehumidifier?
When searching for a new humidifier or for a replacement, strict attention should be paid to the following:
- Extraction Rate: Usually quoted by the manufacturer. It tells the rate at which moist air is extracted from the environment, dried and expelled. Its however very hard to compare extraction rate between two dehumidifiers because manufacturers usually use different rates based on the temperature and relative humidity.
- Power Consumption: This is an important factor to consider since most times on camping we do not have as much power as we have in our homes. The humidifier no matter how efficient it potent to be should not have a diminishing bite on our power supply while camping or in our motorhome.
- Noise Level: The desiccant (or rechargeable) model has less noise level compared to the refrigerator model. But much attention is normally not placed on this as the noise level of both models are unobtrusive.
- Portability: This depends on how often you want to move your dehumidifier around and also the scale of dehumidification you want. The portable ones are always handy and easy to move from place to place.
Additional features such as:
A Humidistat- to measure the humidity level of your RV.
Timer-which enables you set the unit to function for a given number of hours in a day after which it automatically turns off.
Adjustable louvers – which gives great flexibility in redirecting the airflow of the vents. And
Laundry setting-This mode if available makes drying faster.
