Why Are Whole-House Dehumidifiers Necessary? 

Maybe you notice your windows getting foggy or a musty scent in the air. If either of these things are happening, you might have problems with humidity that isn’t properly controlled. It’s not simply rising temperatures to pay attention to, but the moisture levels in your home. Humidity can cause your home to end up with a slew of issues. It can cause parts of your home to break down and deteriorate. 

Nobody likes that sticky feeling you get from excess humidity. But did you know that humidity causes health risks? It’s true. It’s not just about feeling uncomfortable, but also impacting those with respiratory issues, asthma, and induce muscle cramps, flair allergies, and mite populations increase when the humidity isn’t controlled. Let’s not even get started on the sleep issues it can cause. Here’s another thing worth noting. Due to high humidity in the air, infections spread faster than in normal conditions. That’s not all, due to high humidity levels, sweat coming out the body can’t evaporate properly. This causes the body to excrete more water and become dehydrated. As you can see, there are a lot of issues you may not have associated with humidity.

Thankfully, whole house dehumidifiers can alleviate your problems, and here is how:

Mold Prevention

Mold is a type of fungus that causes natural materials to decompose through biodegradation. Large quantities mold causes health risks. When you have too much moisture in the air, it encourages mold growth. The way to combat that is with a dehumidifier. This helps stop mold because it pulls the excess moisture from the area before it can grow.

Side note: If someone in your family suffers from asthma attacks frequently, then you need to install a dehumidifier in your home. 

Improves Indoor Air Quality 

One of the most thorough and comprehensive studies to be carried out looked at the effects of humidity on humans. This analysis revealed that the on the Sterling-Scofield diagram, viruses and bacteria had preferences for low and high humidity. Most fungi prefer humidity level to be above 80% RH. In the case of airborne microbes, the midrange humidity is the least favorable.

So, in order to minimize risk to human health by biological contaminants, the optimal humidity range is between 40-60% RH. Modern dehumidifiers help maintain the humidity level in that range.

Helps Eliminates Dust Mites

Dehumidifiers not only control the humidity levels, they also keeps the humidity at a healthy level. One added benefit is that it can also eliminate dust mites from the air. Dust mites are a big cause of allergies and asthma.

They thrive in humid, warm environments. By eliminating the excess humidity, you eliminate a favorite environment for them, which makes your home less susceptible. You’ll be able to significantly reduce the number of dust mites by controlling humidity levels in your home.

Protects The Structural Integrity Of Your Home

Humidity can destroy the structural integrity of your home. The presence of a high level of moisture can cause wood to warp, crack, or split, especially from prolonged periods.

Then, mold starts to grow and attaches itself to metal on places like beds frames, doors and hinges, or other places that can rust. This slow deterioration can go unnoticed before it’s too late. The simple act of adding a dehumidifier to your home can prevent this damaging effect.

Let alone, you end up with a fresher and healthier environment.

Helps You Feel Comfortable

Due to the presence of moisture, the temperature we feel is higher than the actual temperature of our environment. The humidity makes our skin feel tacky and our bodies uncomfortable, even when we’re not exerting ourselves.

What’s the first thing most people do? They lower the temperature on their air conditioner. But, while we’re trying to cool the house down, we’re using more energy than we need to. The solution? Dehumidifying the home helps lower the amount of moisture in the air and makes us more comfortable. We end up feeling better and being more energy-efficient—a double win.

Do I Need A Whole House Dehumidifier If I Have Central Air?

Unless the central air is specifically built to work as a dehumidifier, it won’t be effective in humidity control. The main job of central air is to maintain the temperature of the environment. It takes the air in, passes it through an evaporator and condenser, which in turn reduces the air temperature.In the presence of the humidity, the space feels hotter than it actual is. This makes  the air conditioner need to run longer, just to cool everything down. Unfortunately, It has to work harder to compensate for the humidity.

How Does A Whole House Dehumidifier Work?

Whole-house dehumidifiers are usually installed to operate in conjunction with the house’s central heating and cooling system. The inlet pipe of dehumidifiers connects to the return ductwork. This draws the air in, cools it to below the dew point, then liquefies the moisture in the air turning it into water droplets. These drops of water fall into a pan, then drain.

Dry air on the other hand passes through the warm coil. This increases the air temperature. This air with the desired temperature and humidity level is then sent out to the rooms in your home. Pretty cool, right?

With a home dehumidifier, there’s a moisture sensor that continuously observes the humidity level in the air. Whenever an increase in the humidity is detected, it automatically turns on the dehumidifier.

What Factors Should You Consider When Purchasing A Whole House Dehumidifier?

To select whether to buy a whole-house dehumidifier or portable dehumidifier is right for you, an HVAC specialist can assess the needs of your environment, family, and home.It’s important to consider the number of rooms, size of the house, and humidity level. If there is only one room or area which needs humidity control, then, of course, a portable dehumidifier is the best choice considering that the area is not much larger. However, for effective humidity control in an entire house with multiple rooms, it is always recommended to install a whole-house dehumidifier for easier use. 

Finally, the operation of a whole house dehumidifier differs based on how it is installed and can be the governing factor between the performances of two similar whole house dehumidifier.

What's The Best Dehumidifier? Ventilating Versus Non-Ventilating Installation

In a non-ventilating configuration, air from a room is taken in, passed through dehumidifiers to extract the moisture from the air, and then that same air is sent back to the rooms.

On the other hand, the ventilating configuration keeps replacing the air from the rooms with fresh air from outside. It takes the fresh air from outside, filters it, extracts the moisture, then sends it to the rooms. This creates consistent circulation.

A ventilating configuration has an advantage over non-ventilating as it provides the building with ventilated air. Clean and dry air is consistently cycled in and out of the house, which gives, many benefits including avoiding mold growth. Adding new fresh air and removing existing air helps eliminate moisture produced inside, smoke, cooking odors, and other indoor pollutants. Good ventilation saves from allergies and asthma.

Can You Tell Me About Portable Dehumidifiers ?

The initial purchase of a portable dehumidifier is less expensive as compared to the whole house dehumidifiers.It does not require any professional installation to start using it. You buy it, place it in the place you want it to you, and plug it in for immediate use.As it is lightweight and size and needs no prior installation for use, you can easily take it to any place or area.They come with digital controls to control their operations easily.


  • It can only be used only in one room or area at a time. Therefore, if you have more rooms in use at a time, you need to buy multiple units.
  • There is a bucket to collect the water coming from the condensation of moisture in the air. You need to empty this bucket from time to time.
  • These units are noisier as these are placed in the rooms you live in.
  • Most portable dehumidifiers do not disclose a CFM rating, which is a very important part of the dehumidification equation. Smaller dehumidifiers with low CFM ratings will not be able to cycle enough air through the unit to adequately affect the humidity levels in larger areas.
  • Portable dehumidifiers have a shorter lifetime as compared to the whole house dehumidifiers and usually, shorter warranties are offered for such units.
