If you’re someone who loves to go on adventures to the countryside or the mountains, you most probably spend the majority of your time within a recreational vehicle. This vehicle acts as your second home for the entire duration of your trip, and it is a place where you perform primary activities such as cooking, cleaning and bathing. All these activities may cause the accumulation of water vapour, mainly since they’re being undertaken in a small, restricted atmosphere. High levels of water vapour tends to generate a lot of discomfort to what was meant to be a cosy trailer, and also affects all soft furnishings found within your RV.

If you’re one, who suffers from allergies or asthma, having excessive humidity in your RV can lead to difficulty in breathing, as well as making life in your trailer unbearable and uncomfortable. Such a bad experience can ultimately reduce your vacation time. However, with a reliable RV dehumidifier around, such issues can be avoided.

Best RV Dehumidifier Buying Guide & FAQ

Things to Look for When Buying an RV Dehumidifier

In selecting the most suitable dehumidifier for your RV, some considerations must be made, to ensure that you purchase nothing but the best.

  • Capacity

The capacity of your dehumidifier is essential information that must be known before purchase. This only refers to the exact amount of water a dehumidifier can hold. If your unit is meant for long trips that may extend past one week, we advise that you buy a dehumidifier with a large water holding capacity. Alternatively, if your trip will be for a week or less, it’s more economical to opt for a dehumidifier with a smaller size.

  • Ease of Installation

Be sure to look out for units that don’t require extensive periods and effort for installation and setup. The smoother the configuration, the faster you can get it to start working.

  • Portability

A portable unit is one that can be moved around with ease. Look out for compact models so that storing them when they’re not needed is easy and quick. If you’re not one to go frequently camping during the year, your best dehumidifier option is one that is easily portable.

  • Controls

Concerning controls on a dehumidifier, you need to find models with user-friendly controls, especially if it is a digital unit. At most the controls must enable you to set your desired humidity level based on category or percentage. A user-friendly control gives users the power to adjust the operations of their dehumidifier.

  • Noise

The noise level of a dehumidifier is a major determining factor before a purchase is made. Check the specifications of various models to find out the amount of noise they produce once they’re in full operation. In order not to disrupt your quiet moments, such as sleeping hours, you can go in for dehumidifiers with minimal operating noise. Typical examples are those that use the Peltier whisper technology, a system that encourages quiet operations.

Benefits of Using an RV Dehumidifier

Here are a few benefits you will expect when using a dehumidifier;

  • Dehumidifier Reduces Humidity That Makes Air Feel Hotter Than It Is

Comfort remains the primary reason why people purchase dehumidifiers for their homes and RVs. A lot of moisture in the atmospheres, the air tends to feel warmer, making life uncomfortable. Our immediate reaction to this is to crank up our air conditioners such that they work harder to cool the space. Extended operations can affect these machines negatively and also affects our energy consumption and utility bills.

  • Dehumidifier Reduces Humid Air That Causes Mold Spores & Dust Mites

A moist environment is a healthy habitat for mould and dust mites. These pests are known to contaminate the air we breathe and can also cause that damp, musty smell we have all experienced one-way or the other.

  • Dehumidifier Reduces Damp Air Which Destroys the Integrity of Furnishings

High levels of humidity help in the development of fungi, mould and rot. These growths affect materials such as wood used for our cabinets, flooring and furnishing, reducing their durability and aesthetic.

  • Dehumidifier Improves Air Quality That is Significantly Diminishes as Relative Humidity Rises

For people with a low tolerance for light-weight allergens, the higher the relative humidity within a space, the higher the possibility of an allergic reaction being triggered. This is because moist air is home for dust, spores, dirt and many other allergens.

Types and Sizes of Dehumidifiers

There are four kinds of dehumidifiers:

  • Dehumidifying Ventilator

These units expel air with help from an exhaust fan. Often used in attics, basements and crawl spaces, this kind makes use of an exhaust fan and a sensor to extract moisture from the atmosphere.

  • Homemade Dehumidifier

There are many ways you can develop your dehumidifier, mostly for short-term use. Substances such as road salt, charcoal and de-icing salt can be used to reduce humidity levels in your home, and you only need to find them.

  • Heat Pump Dehumidifier

To remove moisture from the saturated atmosphere, the heat pump dehumidifier uses a heat pump, fan and heat exchange coils.

  • Chemical Absorbent Dehumidifier

Developed with help from hydrophilic materials such as silica gel, the chemical absorption dehumidifier, also referred to as a desiccant humidifier, is used to extract all types of moisture.

Maintaining Your Dehumidifier

Keep your unit clean by wiping down every two weeks, and using a soft cloth to wash the filter once every month. For storage, the dehumidifier must be kept in a well-ventilated space in an upright position.

Desiccant vs Refrigerant

Desiccants are units that contain materials which hold and absorb water. They operate by passing air through a rotor. The elements in the rotor extract the moisture from the sky and send it to the back of the room.

Refrigerant humidifiers, on the other hand, pull the warm, damp hair from a space, pass it over a cooling evaporator coil which reduces the air’s temperature to a level below its dewpoint.

As both are unique in their functions, preference is best set on what job needs to be performed.

Best RV Dehumidifier FAQ:

Q: How does a dehumidifier work?

Without changing the temperature of the enclosed space, a dehumidifier extracts the moisture in a room which creates dryness in the atmosphere, an excellent setting for the safety of the structure of your enclosure.

Q: Do dehumidifiers use a lot of energy?

Depending on the brand and model chose, dehumidifiers may or may not require a power source. The majority of those that do are designed to be energy efficient thus, helping you save both money and power.

Q: Would a dehumidifier add some heat into my RV?

Dehumidifiers are made to extract moisture from an enclosed space which in turn will reduce its relative humidity. Dehumidifiers that use a power source for operation will expel some amount of heat, but not enough to make users uncomfortable.

Q: What is a good humidity level?

The ideal indoor humidity level is 40-50% RH. This may reduce to 40%RH during the cold days of winter.

Q: What is the lowest temperature dehumidifiers can operate in?

There are dehumidifiers designed for low-temperature areas, and they operate at temperatures below 60 degrees. These can be used in spaces such as basements, which can be heated during the winter to prevent the freezing of the dehumidifiers coils.
