Frequently Asked Questions (FAQ)

Should I run a dehumidifier in my RV?

What size dehumidifier do I need for my camper?

Keep in mind that the power requirements for your machine will greatly depend on the size. You might find that you need two machines depending on the size and humidity levels.

Unless you plan on running your machine on a regular basis, we recommend buying the biggest possible dehumidifier. This will give you a safety net for when the humidity gets out of hand.

For an efficient dehumidifier to work properly, it must be able to remove and circulate air throughout the room. So, you also need to evaluate the size of your room to determine whether or not it will work.

A general rule of thumb for a camper is to get the biggest machine you possibly can. Bigger machines are more efficient and can save you money in the long run.

What dehumidifier does Consumer Reports recommend?

Before you buy a dehumidifier, it’s a good idea to compare features. Consumer Reports tests dozens of dehumidifiers each year. We look for several features, such as efficiency, noise, and size. Our experts considered ease of use for a water tank with a removable bucket, a drain tube, and a filter. We also evaluated capacity and power costs.

Consumer Reports’ dehumidifier reviews look at the following features and more:

Ease of operation: Consumer Reports convenience features range from LED lights to filter indicators and defrost systems.

Capacity: How much moisture the dehumidifier can remove from the air.

Murphy says, “This is important because it affects how often you’ll have to empty the water bucket and how much water will be sitting in your basement.”

What are the top 10 dehumidifiers?

The best top-selling and most popular dehumidifier is the Eva-dry Renewable E-500 because of its unique features, portability, light weight and power consumption. It can be run through wall outlets (110-120 V) or batteries and it can be used for a wide range of purposes.
