Basement Dehumidifier Buying Guide

This is a very good video from the Consumer Report's Team.

Basement Size

This is the easiest one to work out. It is simply the length of the basement measured in feet multiplied by the width of the basement also measured in feet. So for example if the basement was 32 feet long and 24 feet wide the square feet size would simply be 32 x 24 which is 768 square feet.

The reason this measurement is important is that most manufacturers will state on their dehumidifier what square feet size the unit is designed to handle. This measurement is simple to do and makes a very good starting point.

Amount of Water in the Air

Some basements will have dry air and in that case a dehumidifier will not be required. In fact in very dry basements, a humidifier may be required.

Some basements may be a little damp, moderately damp and others can be very damp. That matters as dehumidifiers have a tank capacity. This is where the moisture from the air is turned into water, and then held in a bucket inside the dehumidifier.

You can measure the humidity easily. This can be done with something as simple as a humidity gauge, or a humidity meter. These are called generally speaking hygrometers. These are not that expensive with an average cost of around $9-15.

We don't want to get over technical, but they measure what is called relative humidity. For your general health and comfort this humidity reading should sit anywhere between 40-50% on that scale. Anything greater than that means there is simply too much moisture (water) in the air in your home.

We would recommend the Habor Digital Hygrometer which is under $10, and gets great reviews online.

Air Temperature

The temperature in your basement is also very important, when it comes to buying the right dehumidifier. The temperature will depend on the weather, but also on the ventilation (or lack of ventilation) in your basement.

The main reason we include temperature as a measurement, is that refrigerant style dehumidifiers, may freeze up if the temperature in the basement drops below 59 degrees Fahrenheit. You can buy units with auto-freeze protection, but they are more expensive. However, the general point is that they will stop working if the coils inside the unit freeze over.

There are two types of dehumidifier:

  1. Desiccant
  2. Refrigerant

If you live in an area, where the basement temperature can get cold, then you are better to buy a desiccant type of dehumidifier, as they don't have coils and as such can not freeze.

In warmer climates, the refrigerant model is a better option as they are generally speaking more efficient.

How Do Basement Dehumidifiers Work?

These work by using a fan, which pulls in the surrounding air, and then makes that flow over 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.

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.

Energy Star Compliant is awarded to products and ensures that they contribute to making the best use of energy in terms of efficiency.

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.

Ventilator, Dehumidifier or Both?

If someone is gong to be sleeping or working in the basement, then a ventilating system working in conjunction with a dehumidifier is by far the best option. The ventilation in a basement really does depend on how it was constructed and built in the first place.

In any basement, ideally you want to have what is called natural ventilation. That is simply a method where air can flow in and out of a basement. This is as simple as something like two windows facing each other, and when opened they create a natural airflow.

If the airflow with a setup like this is too low, then a simple way to fix that is to install window fans. One should be set to draw the air in, and the other set to exhaust the old air.

Sometimes even those may not be enough. At that stage we would recommend getting expert advice to get a proper ventilation system installed.

Basements are often used to store paint, gas and other materials. Any humidity along with those smells would be unhealthy for anyone working or sleeping in a basement. Good ventilation is an absolute must, and a dehumidifier will work well with that to remove excess moisture.

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.
