Best Basement Dehumidifier

Basements up and down the country can typically suffer from dampness, mildew and stale odours. All of these are caused simply by having too much moisture in the air and that is caused by a lack of thorough ventilation.

Basement dehumidifiers are simply the best solution available to remove damp mildew and prevent mould from growing. They typically cost around $200 for a 75 pint machine. These work by using some type of fan, which pulls in the surrounding air, and then makes that flow over two coils which are very cold.

This makes the moisture in the drawn in air turn to water. When that happens the water then drops down into a bucket. In the simplest of terms, the water or moisture in the air is removed, before being pushed back out again. It is a simple but quite clever process.

If you live in a cooler climate, then for your basement you should give serious consideration to a low temperature dehumidifier, as they ave the capability of continuing to draw moisture even at lower temperatures. There are many different features available on these dehumidifiers, and the guide we have produced below, takes you through those.

Let’s start though with a very good video from the Consumer Report’s Team.

Dehumidifier Brands

The leading brands in dehumidifiers such as Frigidaire, Danby, Delonghi and Soleus all have leading lines in basement dehumidifiers, so personally we would recommend that you stick with those. You may find other smaller brands out there, but the ones that we have mentioned above do produce good quality products.

Tips When Buying A Basement Dehumidifier

There are several important features to consider before you purchase a dehumidifier for your basement and we have highlighted these below. One of the most important considerations of all though is where will you actually be placing this? These are not quiet appliances and the noise can get to you after a while.

Within the home itself these can get very noisy. In a basement this might not be an issue, but just be aware that these can have a constantly loud enough sound to be REALLY irritating.

Automatic Shut Down

We would class this as a mandatory feature. This feature ensures that the machine will close down when the bucket is filled and will avoid a complete mess. Just picture what the scene could look like if you did not have this feature and let’s face it who wants or needs a flood.

Our advice is just not to buy a dehumidifier that does not have this feature. Most of the newer models do. Older models did not have this, so if you are changing those out, insist on this feature.

Energy Efficiency

If you are running any appliance then you want it to be as efficient as possible. Thankfully almost every dehumidifier has now been made to pretty exacting standards. They still cost money to run though, and the bottom line is, the more efficient the appliance, the less it costs to run.

Automatic Restart

Many homes suffer from power outages. Having this feature will ensure it restarts when the power comes back on. This is especially important if you have a dehumidifier in a holiday home. Some of the more advanced appliances will also remember your actual settings.

Built In Pump

Few dehumidifiers have a built in pump which we would recommend. If you decide against this then we would recommend a continuous gravity drainage rather then having to constantly remember to empty buckets. Make sure your dehumidifier has either a Patented pump like that you find in a Danby or the option of a garden hose attachment.

Low Temperature Feature

This is a must have feature if you live in a cooler climate. Low temperature dehumidifiers will still function at temperatures below 65 degrees. Below this appliances without this feature are prone to water freezing on the coils of the appliance and producing a build up of ice. Eventually this will stop the fans from working and burn out the motor. This is a common problem so make sure you have this feature if you live in a cool climate.

Auto Defrost Feature

Similar to the above the auto defrost feature will turn off the appliance’s compressor when the desired humidity level has been reached. This also prevents the coils from becoming covered in ice.


We hope that this guide has helped you to understand what to look for when it comes to buying a dehumidifier for your basement. The reality is that most basements in home, simply because of their location, attract a certain amount of dampness.

All you can really hope to do is to control that dampness. Take some preventative measures that will help reduce the moisture in the air. One great tip is to make sure that any down spouts and guttering is clear of debris and leaves. The purpose of those is to keep rain away from the walls of your home.

It is also a really great idea to apply some type of waterproof coating to the walls and floors of a basement. The more moisture you can keep out the better. What’s left in the basement, can then be quickly removed with a good quality dehumidifier.
