Best Dehumidifier for Basement Reviews & Buying Guide of 2016

Do you have a basement in your home? Well, that cool and damp unpleasant smell is actually mold and mildew caused by too much moisture in the air. If you can detect a pungent odor, you probably need an effective dehumidifier. Take action. The growth of mold can be extremely damaging for your home and your health. Buy the best dehumidifier, say goodbye to excess moisture and safely reduce the humidity to proper levels.

Once the humidity level is below 50%, the space will seem fresher. At last, you can put your stored possessions and paperwork in the basement without having to worry about mildew. Along with the musty smell, there are other common warning signs for humidity. Look for condensation on the floors and walls. Be watchful for any physical presence of mold. When mold spores become airborne, this can impact negatively on your respiratory system and trigger asthma attacks or allergic reactions.

The dampness from excessive moisture can cause the foundation and walls to rot. This leads to structural damage and the risk of health problems.

We will help find the right dehumidifier for your basement. Get rid of excess humidity once and for all. You need the right equipment for the job.

So, let’s first explore the basics.

Find out what you should know before buying a dehumidifier…

How does it work?

A dehumidifier helps to remove moisture from any space and makes the air drier. The moisture in the air is sucked into a grill as the electric fan draws the air through the evaporator and turns it back into liquid. This liquid is then collected in the water tray.

The remaining air is then sucked through the heater to warm up the space.

What’s Inside a Dehumidifier?

Dehumidifiers are pretty standard in their build. Their parts are basic:

  • Fan
  • Water tank
  • Compressor
  • Coils

Some models include an added air filter as well.

Harmful effects of Humidity

A humid environment is the ideal place for microscopic organisms and bacteria to grow.

Mold and mildew spores thrive in humid conditions. They can then become highly toxic when they enter your body.

Dust mites can also be a serious issue if you suffer from allergies and asthma.

Bottom line: bacteria absolutely love humid spaces. Being exposed to mold growth can cause you to get sick more often and result in general poor health.

Popular Symptoms of Allergies

  • Stuffy nose
  • Itchy, watery eyes
  • Skin rashes
  • Difficulty breathing

You may notice an unusual smell coming from the clothes, purses or shoes in your closet. When a kitchen or bathroom has little to no ventilation, the humidity will raise and cause bacteria to develop quickly.

Benefits of a Dehumidifier

We can see humidity in the steam coming from a hot shower, a sauna or even outside on a foggy day.

Indoor humidity leads to many health risk and problems in the home. It’s wise to safely lower the levels with a dehumidifier. Don’t take a chance when it comes to your wellbeing.

Humidity can affect electric equipment like the TV or computer. It can also create mold in living spaces. This is harmful to your health as it can lead to respiratory diseases.

Another benefit of a dehumidifier is in reducing dust without the hassle of cleaning so much.

Creating dry hair also helps with the air conditioner. The AC won’t need to work as hard at removing moisture and cooling the air. With the dehumidifier, your air conditioner only has to create cool air.

What Features Does a Basement Dehumidifier Require?

It is important for a dehumidifier to be able to work in lower temperature environments. Basements are usually cooler than the rest of the areas in the house while covering a large amount of floor space.

Dehumidifiers for the basement must be capable of extracting 100% of the moisture in spaces of at least 2,000 square feet.

Here are some important features we should consider…


The dehumidifier must have appropriate removal capability along with the right coverage for the size of your basement. The bigger the area, the better is it to have a larger capacity dehumidifier.

Water Collecting Tray

Since the dehumidifier is working to control moisture, it is important to know where that water will go. Consider the capacity of the product as well as its volume.

If you do not want to spend lots of time emptying the tray, it’s essential to choose a model built to keep this annoying task to a minimum.

If you plan to pop your device in the basement, a hose connection will direct the vapored water straight to the drain without needing a tray. If your home does not have a drain, a simple pump will be sufficient to send the water to the sink or any drains through the window.

Auto Defrost

This is used to prevent the coils from freezing while allowing the dehumidifier to continue removing moisture.

Low temperature Operation

Dehumidifiers with low temperatures are ideal in cool climates as they will continue to draw moisture out.

Humidistat/Built-In Hygrometer

This allows you to set the precise humidity level you require.

Continuous Drain Option

This will ensure that the dehumidifier will continue to remove excessive moisture without the stress of repeatedly emptying water buckets.

Automatic Restart

This feature is useful when it comes to a power outage. Your dehumidifier will restart as soon as the power is restored.

Automatic Shut-Off

For dehumidifiers that don’t offer a draining option, make sure it has an auto shut-off. This will help to prevent overflowing.

If the water tray gets full, the machine will automatically shut off to protect the machine and reduce the risk of water overload.


A timer is ideal and can come in very handy if you tend to forget that your dehumidifier is on. It will also lessen your electricity bill as the rates are lower at certain times of the day. You can run your unit during these periods to save money.

The device will easily turn back on after a power outage. It will also switch itself off when you are out. This is another great money saving feature since the longer the machine runs, the more energy this device uses.

User-Friendly Settings

Search for models with wheels to enable easy maneuverability. Also look out for products with easy-to-read settings and dials.

Dehumidifiers with digital settings are generally simple to read and understand.

What to Look For In Particular

Think about exactly how and where you will use your dehumidifier.

Make sure to study user reviews that highlight performance, ease-of-use, warranties, and other key information.

Knowing the size of the space and the amount of moisture you want to remove is important. This will determine what type of dehumidifier is the best fit for your needs.

For large floor coverage, you will need a high-capacity dehumidifier that will remove at least 70 pints of water vapor in a day. Make sure not to purchase anything smaller as it will prove false economy.

Check the manufacturers’ list to get a proper estimate of the minimum and maximum footage the model can manage.

Why Use a Dehumidifier?

Whether you have a basement that needs the humidity levels regulating or live in a sticky climate, a dehumidifier will help keep excessive moisture in check.

When a home is too damp, it is prone to produce fungus, mold and mildew. This can cause harmful effects present on the walls, furniture and even clothing.

Extreme amounts of humidity can also create a home for viruses and harmful bacteria that can gravely affect your health.

You should aim for a low humidity level of 30% and nothing higher than 50%.

Dehumidifiers are available in all sizes so you can choose the right one for your home.

Types of Dehumidifier

There are two main categories of dehumidifier, desiccant and refrigerant.


The structure of this type includes:

  • Rotor
  • Process fan
  • Reactivation fan
  • Honeycomb matrix

How does it work?

The process begins with damp air being led to the machine by a process fan. This air is then whisked directly to a honeycomb matrix.

There, the rotors will absorb the moisture as the dry air is released. The rotor contains desiccant materials in the form of silica gel. When damp air passes through, moisture is sucked out through a network of microscopic intertwined pores.

The reactivation stage makes the absorption force weaker so the moisture is able to escape from the desiccant materials.


The structure of this type includes:

  • Fan
  • Water collecting tray or pipe
  • Cold evaporator coils
  • Warm condensing coils

How does it work?

The kind of technology works by condensing the humidity to help get rid of all the moisture in the space.

Damp air will be sucked by the fan and lead the air toward the cold evaporator coil for cooling. This makes the moisture turn into liquid water that is collected and removed either manually or through a drain.

The air will then proceed to the warm condensing. This heats it up before being released.

Desiccant vs Refrigerant


The refrigerant coil weighs more as it includes heavier parts. Due to the weight, manufacturers usually include wheels for easy mobility with refrigerant models.


Because of its smaller size, many assume that desiccant dehumidifiers are cheaper to run than those with refrigerant coils. In fact, the refrigerant runs on less energy.


Desiccant dehumidifiers are a fair bit quieter than refrigerants. Refrigerants use compressors to get rid of moisture from the air so kick out more noise.


The refrigerant coil is able to remove a large amount of water vapor each day. In areas with high amounts of moisture, this type works best.

Temperature Operation

The refrigerant coil dehumidifier uses cold air to evaporate moisture. The desiccant variety uses the porous form of granular silica to get rid of humidity without any unwanted heat.

How much does a dehumidifier cost to use?

Typically, the usual power consumption is about 150 to 800 watts. Dry air is cheaper to heat which means this tool can be a real help saving energy.

Dehumidifiers don’t just warm the hair but also capture the moisture and remove any dampness from cold air. You can save even more by purchasing a dehumidifier with a built-in laundry function mode. This will produce warm dry air when positioned properly.

What is a Pint?

A dehumidifier uses the pint for sizing. Pint is a volume unit that is used in both UK and US measurement systems. It was 1/8 of a gallon though the US pint is 20% smaller than a pint in the UK.

UK: 1 pint = 568 ml

US: 1 liquid pint = 473 ml and 1 dry pint = 551 ml

What size do you need for your home?

Both weight and height are important considerations. Think as well about the amount of water removal needed each day. The more water you need to get rid of, the larger capacity dehumidifier you will need.

If the space is not always damp, choose a smaller capacity dehumidifier.

Where to put the dehumidifier?

Choose the area where the most humid and damp conditions occur. This can be the kitchen, bathroom, basement, or in a hallway.

Make sure not to run the dehumidifier in the room you are in (or sleeping in).

Can I leave the dehumidifier on all day?

Many manufacturers say this is fine although exercise caution. There is always some risk with any electrical appliance.

However, a commercial grade dehumidifier is an exception since it is built to run constantly without burning out.

Factors to Consider

Add 10 pints if you live in a high humid climate.

If there are many people living in your home or your house contains many windows and doors, add another 5 pints.

If the area has a wash and dryer, add 5 pints

Refer to the Appliance Manufacturers guideline to determine the size that is most appropriate for your home.

Here is a useful way to determine how many pints your space needs, depending on size.

Under 30 Pints: This is acceptable for rooms of up to 1500 square feet. These models are perfect for smaller basements or 1000 square feet spaces with high humidity.

40-50 Pints: This size is used for areas up to 2000 square feet as well as spaces that suffer from damp all the time.

60-70 Pints: This is the advised capacity for spaces larger than 2000 square feet.

Follow these simple, important steps and you can choose the dehumidifier that is right for your home.


When it comes to humidity, feeling overly sweaty and uncomfortable is the least of your worries…

A moldy stench, crooked floors and peeling wall paint are all signs that you should definitely buy a dehumidifier before it’s too late.

As with anything in life, prevention is better than cure. Investing in a dehumidifier is very worthwhile. You cannot put a price on your health.
