4 Points You Need To Know:What Does A Dehumidifier Do


More or less, you may suffer from the problems caused by high humidity, stains in the wall, mold on the furniture made of woods, damage to your electronic devices, and even the harmful effect to your body.
There are many reasons for high humidity in your house or office, such as weather, the location of your house or office, bad air circulation, and so on. That's why it's difficult to avoid the high humidity for good.
But we are able to avoid the harmful effects caused by high humidity.
We have written an article about a humidifier, sharing some knowledge about the risk of low humidity. In this article, we will share some content about high humidity, and what does a dehumidifier do to solve all the problems high humidity leads to. Finally, we will show you how to choose a dehumidifier that is suitable for your own condition.

1. What Is A Dehumidifier?

Before getting into the topic " what does a dehumidifier do", it's necessary for us to have some basic knowledge about dehumidifiers

A dehumidifier is an electrical appliance that can reduce and maintains the level of humidity in the air. People always use it for health or comfort reasons. 

By extracting water from the air, the machine can efficiently eliminate musty odor and prevent the growth of mildew. The device can be applied in many different conditions, including house, office, shopping mall.

Dehumidifiers are generally divided into condensing dehumidifiers and rotary dehumidifiers. We generally use condensing dehumidifiers at home. 

With the help of compressor refrigeration, condensing dehumidifiers condense the vapor in the air into water, reducing air humidity to achieve the dehumidification effect.

2. What Does A Dehumidifier Do?

(1).Dampen the breeding of bacteria and viruses

Bacteria and viruses can have good breeding in the environment with high humidity. Studies have shown that: bacterial and viruses thrive in the air of over 60% relative humidity. Living or working in such an environment can easily make you suffer from some illness, especially respiratory infections

What's more, the pollutants in the air can stay longer because of humid air before setting to the surface. So when you're in a humid office with people sneezing and coughing all around you, those nasty germs can linger and multiply. And you are more likely to inhale them.

Allergy sufferers need to be more careful in the humid environment, which leads to higher levels of dust mites and fungus. These are the worst culprits for allergy sufferers.

It's well-known that molds and fungi can easily aggravate respiratory illnesses such as Asthma. Even One without allergies or asthma can have allergic reactions to fungi. Most of these microorganisms multiply on a crazy scale in environments where the relative humidity breakthrough 75%.

Even if you can't see them, they may be in bathrooms, kitchens, carpets and furniture, and ceiling tiles in offices. They may even be growing in your air conditioning ducts.

These are the first benefits a dehumidifier can provide. A dehumidifier can help in damping the breeding of bacteria and viruses, solving problems at their source.

(2).Avoid deadly effects of high humidity

No matter indoor or outside, too much humidity combined with high temperatures can cause the overheat of our bodies, which will be dangerous to us.

Have you ever wonder why hot and humid air is more uncomfortable than hot and dry air? Mostly because humidity will impede your body to regulate body temperature.

If you stay in an environment with too much humidity, your body temperature can not help to rise.
When temperatures get too hot, the defense mechanisms of your body will work to keep your internal temperature steady. These include:sweating, increased respiration, altered blood circulation.

Among these three methods, Sweating is an important and common one.

Sweating cools the body when the moisture evaporates from the skin. However, when the air is already saturated with water vapor (as it is when humidity levels rise to 70 percent and higher). Sweating can't make the moisture from the skin evaporate. So instead of cooling down, you just feel hotter and stickier.

At that point, the body is forced to resort to other means to cool off increased respiration and altered blood circulation. That's why you can find that you breathe in an increasingly rapid way as you get hotter. Your heart will pump more blood to your extremities. That means that the blood to your internal organs and your brain will be less. That's why you will feel dizzy and foggy. 

Finally, if your body in such a condition for a long time, you may get heat exhaustion or heat stroke, which can be fatal.

(3)Problems to the living environment

Some daily life products, such as carpets and wood products, can release chemicals such as formaldehyde into the air. This is called "off-gassing".

When there is too much humidity in the air, the concentration of these harmful chemicals rises due to the reaction of the chemicals with water vapor. 

Even low levels of exposure to these chemicals can cause irritation of the skin, eyes, and throat as well as respiratory symptoms.

(4)Solve Health problems caused by high humidity

Respiratory allergies: Researches has confirmed that the air with high humidity is conducive to the reproduction and spread of some bacteria and germs. Humid environments are most likely to produce mold. Inhaling mold into the lungs can easily cause pneumonia or pulmonary fungal disease. 

Mold and its metabolites enter the body through various channels, triggering allergic bronchitis, bronchial asthma, hay fever, dermatitis, etc., or making the original allergic diseases recur.

Cardiovascular and cerebrovascular diseases: The large changes in the weather such as air pressure, temperature, and air humidity during the rainy season can easily lead to disorders of the body's plant nerve function, vasoconstriction, obstruction of blood flow, increased blood pressure, increased myocardial oxygen consumption and increased heart load, thus triggering myocardial infarction, stroke, and other cardiovascular and cerebrovascular diseases.

(1) Area

First of all, according to the area we want to use a dehumidifier, we can estimate the corresponding dehumidification amount

In general, you can estimate the amount of dehumidification in 0.6 per square meter per day. And the detailed parameters also have reference to the use of the area.

Of course, also relative to the actual situation of the specific use of space, such as the pattern of space, the degree of openness, the intensity of sun exposure, ventilation, the number of people, and so on. 

For example, if the intensive space is connected with other places, or you want to use the device in a space with strong sunlight, a large cooling capacity of a dehumidifier would be more appropriate.

(2). Location

Different use of the site determines the size of the water tank. space for the use of a Domestic dehumidifier is generally the bedroom, living room, kitchen, and bathroom.

The bathroom is very convenient for drainage. Nowadays, the hose will be provided for free when you buy a dehumidifier. In the kitchen, you can put the dehumidifier on the countertop for drainage.

But the bedroom and living room do not have any place for water drainage. If you choose bedroom and living room as main space for using, you have better choose a dehumidifier with a large-capacity tank. So the dehumidifiers can work for a long time.


The difference between the dehumidifier compressor and humidity sensor module causes the price difference.

If the budget is not a big problem for you, we advise you to choose a good compressor and humidity sensor module. Which have long durability and better ability in humidity control.

(4). Other Features

Other than the main function, some dehumidifiers will have additional features, such as negative ions, ozone, dust removal, etc., 

We should choose a dehumidifier in the guidance of our demand rather than the desire to have a dehumidifier with as many as functions it can.

If you are sensitive to noise and want to use it in the bedroom, it would be appropriate for you to buy an ultra-quiet dehumidifier. If you are sensitive to the air, you can choose a dehumidifier with a negative ion function or dust removal function.

In a word, what you want to buy should be based on your demand.

4. Maintenance of dehumidifiers

(1).Review your owner's Manual

All of the information you need to know about the dehumidifier you buy will be included in the Manual. So before using the machine, it would be better for you to review the owner's manual.

(2). Replace the air filter regularly

Most dehumidifiers have an air filter to remove impurities, providing clean and healthy dehumidified air. It's unavoidable that particles will be collected in the filter. A filter congested by impurities will impede the flow of the air. In such conditions, the dehumidifier works harder, increasing the cost of energy. That's why we advise you to replace your dehumidifier's air filter according to the time frame provided by the owner's manual, maintaining optimal performance.

(3).Clean the water container Frequently

Emptying your dehumidifier's water tank is not enough. We advise you to clean the water tank with soap or some kind of cleaner. Just consider that otherwise, the water tank will be a breeding ground for mold and bacterial, you can understand the necessity.

(4) .Don't Short-Cycle the Compressor

Turn your dehumidifier off after at least 10 minutes you turn on it. Such doing can allow the pressure in the system to equalize and avoid damage to the compressor. Turning the dehumidifier off and on quickly can lead to overheating and even the circuit-breaker of your machine.
