Why Do You Need Dehumidifier?

In spring and summer, most people complain about discomfort caused by increased levels of humidity. For some, it may because of the weather outside. Or moisture coming from stovetop cooking and drying laundry inside the house.

What is Humidity?

Why should you give a moment’s thought about indoor air quality?

Humidity is one of the most common issues discussed when we talk about the quality of air inside your house. It is defined as the number of water molecules present in the air. That’s why we say, air contains water.

Indoor Humidity Matters

The amount of water vapor in air changes when the temperature changes. Warm air holds more water than cool air. That’s why we often complain about the high humidity in summer. When the air is totally saturated, we say the relative humidity is 100%.

As such it cannot hold more air. In such conditions, it is likely to rain outside. But indoors, it presents a whole set of problems. First, it makes it hard for the body to lose water through sweating. Second, it makes the air feel musty and stuffy.

High indoor humidity causes structural problems. You will notice mold growing on walls, cupboards, wall units, etc. 

You may see wet stains on walls and ceilings or even rotting wood. Excessive humidity poses a health risk to your household. According to Environmental Health Perspectives (EHP), relative humidity of above 50% increases the survival of airborne infectious bacteria and viruses.

The high relative humidity is not good for computers and electronics. It can cause rusty components and short circuits. Lastly, excessive indoor humidity overburdens your AC. When there’s too much moisture in the air, your air conditioner has to work extra hard to achieve the ideal environment inside your home.

Ideally, you should aim for a relative humidity of around 30-50%. If this range is difficult to achieve, then it’s important to invest in a good dehumidifier.

How do they work?

Dehumidifiers regulate the amount of moisture in the air. They pull the gaseous water into their system and then convert it into liquid water. There are two ways a dehumidifier can achieve this.

Refrigerant Dehumidifiers

A refrigerant dehumidifier has five major components to regulate humidity.

Fan- it draws water vapor from the room into the dehumidifier

Fan Compressor- It expands and compresses the refrigerant in the process of cooling the dehumidifier’s coils.

Cooling coils – They contain the refrigerant. The coils are cooler than the air. The condense the water vapor and convert them into water droplets. They work using the principle that cool air cannot hold as much water vapor as warm air.

Reheater- As the water vapor is condensed, heat is generated. The reheater captures the heat and releases it into the dehumidified air before it is restored to the room.

Reservoir- The water droplets collect into the reservoir. It is a container or a drip pan that needs to be emptied from time to time. If you constantly forget, you can connect the dehumidifier directly to a drain.

Desiccant Dehumidifiers

These dehumidifiers do not use condensation to remove excess moisture from the air. They use a chemical (the desiccant) to adsorb/absorb moisture from the air.

There are different types of desiccant dehumidifiers. They range from disposable ones like the silica gel that comes in a new pair of shoes. To consumer and commercial-grade desiccant dehumidifiers.

A consumer-grade desiccant adsorbs moisture. It can also release it back into the air when it’s heated. This type of dehumidifier consists of a large rotating drum. The drum removes moisture from the air as the air is drawn into the system.

It also consists of a condenser to turn the water vapor into liquid water. A heater reheats the air and a blower exhausts the air back into the room.

Factors to Consider when Buying a Basement Dehumidifier

By now, you’ve already seen the tell-tale signs of a basement in need of a dehumidifier. Here’s what to consider before you pick a model.

Drying Capacity

Consider the level of humidity in your basement. You can know this by measuring the basement’s humidity using a room humidity monitor. The amount of moisture a dehumidifier can pull is measured in pints per 24 hours of continuous use.

The drying capacity goes hand in hand with the dehumidifier’s size. After you know the basement’s moisture levels, next is its size in square feet.

That is why dehumidifiers come with a sizing chart. It allows you to match the dehumidifier to your room size. Some models can remove as much as 140 pints of water a day in 60% relative humidity and 80 degrees temperature.

In basements, the sizing chart may not be a straightforward method of knowing the ideal model to pick. This is because the chart does not consider the height of the basement. If you are dealing with a large space with ample airflow, you may not need an ultra-big dehumidifier.

This is because the airflow is good and the dehumidifier’s work becomes easier. It is better to go with a higher capacity model than your area size recommendations.

Here’s a brief chart showcasing the drying capacity of dehumidifiers.

Standard conditions are where the temperature is 80 degrees Fahrenheit and relative humidity is 60%. A large-capacity model in such conditions is rated for 50-75 pints per day. Medium capacity is rated for 45-50 pints per day. While a small capacity machine has a drying capacity of 45 pints per day or less.


Your machine consumes energy to regulate humidity. The energy performance is the drying capacity of a dehumidifier in an hour versus the amount of energy it consumes to remove that much water. 

Look for dehumidifiers with the Energy Star label.

Water Capacity

How much water can a dehumidifier store in its drain container?

Some models come with small tubs that need changing every few hours. Others have a self-draining feature where you can connect a hose to an outside drain. 

This way, you will never need to empty a drain container. Some double as air conditioners. In this case, the dehumidifier has an evaporation feature. It removes the water instead of connecting to a drain pipe.

Machines that have the latter convenience are more expensive than those that need emptying.

Noise Level

When looking at indoor comfort, noise is something you don’t want to deal with in a dehumidifier. You’ll want to look at dehumidifiers that do not give off too much noise. You can test the noise level at the store or read reviews when buying online.

Indoor Temperature and Range

Basements tend to be colder in winter. 

And dehumidifiers are affected by indoor temperature. Most dehumidifiers give off air at 30% relative humidity. When the temperature is at 70 degrees or higher, a dehumidifier can reduce moisture to 35-40% relative humidity.

As the temperature drops, the dehumidifier will not be working as hard as it should. Most of them only work in temperatures above 65F. Otherwise, water freezes on the condenser coils.

If you plan on using a dehumidifier in winter, it’s better to pick a low-temperature model. This type of unit can work in temperatures as low as 41F. If you pick a regular dehumidifier, it will only work when the temperature is optimal.

Features to look for in a Dehumidifier

Automated Controls

Automated controls are desirable in a dehumidifier. They monitor and set the relative humidity levels. An auto humidistat can sense the humidity level around the dehumidifier. It automatically shuts off the machine once the ideal humidity level is achieved. This feature helps to save energy.

A built-in hygrometer is another nice feature. It measures the relative humidity and lets you see the number on the display.

Direct Drain

Dehumidifiers automatically shut off once the drain container fills up. It means the unit will not be operational for the hours you are not available to empty it. instead, opt for a direct drain that feeds water outside through gravity. This way, it can always be operational even when you are not around.

Internal pump

It automatically pumps water down so that you don’t have to place the unit in a high place.

Defrost Feature

As we said, dehumidifiers are designed to work above 65 degrees Fahrenheit. An auto defrost feature prevents the coils from freezing. Remember that ice can damage the coils and cut their lifespan.

Filter Indicator

It tells you when it’s time to wash the filters. Cleaning the filter is part of maintaining the dehumidifier. This way, it can work in good condition for a long time. Go for washable filters. They spare you the expenses from constant replacements.


The dehumidifier resumes operation from its previous setting after a power outage. Or after auto shuts off when the tank is full.

What kind of dehumidifiers are there?

Dehumidifiers are identified by the way they work and by their size.

Refrigerator-Style Dehumidifiers

This is the most common type of dehumidifier used in homes. It takes in the humid air, removes the moisture from the air by cooling it, and releases the air back into the room. This type of dehumidifier is a top seller as it has proved effective.

Well, until you try to use it when it is extremely cold. The unit relies on condensers to cool the air. If the air extremely cold, the cooling coils freeze. Thus, they are only ideal in a typical environment where the air is warm.

Desiccant Dehumidifiers

This type of dehumidifier does not depend on a refrigerant to cool the air. The air is simply passed over a desiccant chemical which absorbs the moisture. That’s why it is capable of working in subzero temperatures.

Desiccant dehumidifiers range in size from small packets to large commercial-grade models.

Whole House Dehumidifiers

You may pick a small dehumidifier for the basement. But if you are dealing with moisture all-around your home, it’s time you picked a whole-house dehumidifier. These dehumidifiers are not plug-and-play. They require professional installation.

They connect to the existing ductwork of your home or that of the air conditioning system. 

Portable Dehumidifiers

These are the most common dehumidifiers for medium-sized rooms. They don’t need professional installation. You just plug it in and it’s ready to do the job.

Portable dehumidifiers are quite affordable. The only thing you need to do is wash the filters and have a reliable way of draining the water it collects. And, remember to match its drying capacity to your needs.

Mini Dehumidifiers

For small spaces, you are better off with a mini dehumidifier. We are talking closets, bedrooms, nurseries, and cramped spaces. These models are inexpensive. They are capable of dehumidifying the spaces they are designed for. But because of their size, don’t expect much if you are dealing with excessive humidity.


Q1. What exactly does a dehumidifier do?

Ans: This is a simple appliance designed to remove excess moisture from indoor air. It, in turn, makes that space comfortable and healthy for its occupants.

Q2. Where does the water collected go?

Ans: When a dehumidifier condenses water vapor into droplets, the liquid collects into a plastic tank. The container needs to be emptied or directed into a drain.

Q3. How do I choose the appropriate dehumidifier for my moisture problem?

Ans: Dehumidifiers are rated with their drying capacity and the area they can cover. You can use the chart we outlined above to identify your moisture problem. After that, you can match it to the right size dehumidifier.

Q4. Where should I place my dehumidifier?

Ans: The placement of a dehumidifier depends on lots of stuff. But the best position is in the center of the room. At the center, it can draw air and at the same time have access to utilities. As you do this, ensure that all the windows and doors are closed.

Dehumidifiers with a horizontal air discharge need at least 12 inches of space around it. But if it has a top discharge, you can go ahead and put it against a wall.

Q5. Are there other ways to reduce moisture in my home?

Ans: Reducing moisture is based on the typical cause of the moisture problem.

If water collects outside of the basement wall, you may have inadequate grading. As such, you will have to backfill the area with soil. Make sure the earth slopes away from the foundation wall. It is recommended to do this at an inch per foot for a minimum of six feet.

In other cases, your basement may lack a subsurface drainage system or the system doesn’t work. You may also have missing gutters or the window wells are not properly designed.

Overall, you are looking to remove internal moisture sources like clothes drying. And, fixing exterior moisture sources like surface water, downspouts, and gutters.

Dehumidifiers are not a permanent solution if the cause of the problem is not corrected.


The best dehumidifier for basement should be optimized for your needs. It should work effectively to remove excess moisture. And also prevent damage to the room and its contents. That’s why we’ve picked only the top-performing units capable of the job.

Remember that basements have higher humidity levels than other rooms in a home. Our top picks cover modest to extreme needs. They can remove 30 to 70 pints of moisture per day. You’ll also find models that can work in low temperatures like the Frigidaire FFAD7033R1.

We are hopeful that one of these brands will meet your dehumidifying needs.
