Why do we need a dehumidifier?
1. Excess humidity is a treat for potentially harmful microbial growth
Ever you heard something about the unhealthy places saying dark and dump? Moist places or excess humidity is heaven for microbes. It is all they need to grow. The best option is optimum humidity which suits best the human life. And to attain this, we need a dehumidifier.
Dust mites are in love with high humidity. And it is extremely unpleasant to think that how much dust mites can be around you in a place with high humidity. The earlier effects are runny nose, watery eyes, and sneezing and in severe cases, it can lead to Asthma.
Molds are the pet issue of high humidity. Adverse effects of molds on health include allergies, nasal stuffiness, eye irritation, cough, and skin irritation.
2. Low-indoor air quality:
Environmental protection agency (EPA) has listed the poor indoor air quality among the top health risks. And the important component of indoor air quality is humidity. Excess humidity makes the air more suitable for pathogens, and less suitable for humans. Many of the potentially harmful bacteria, viruses, fungi, and insects tend to grow in high humidity- higher than suitable for humans.
Poor indoor air quality has many adverse effects but respiratory infections are worst of them. It can cause allergies and infections in respiratory tracts.
People spend almost 90% of their time indoors, on average. And 65% of this they spend at home. This is extremely important the air we breathe in for a maximum of our life should be clean, fresh, and healthy.
What causes indoor air to be polluted?
Excess humidity is the key factor for low indoor air quality. Some of the factors are purely produced by excess humidity while it also magnifies the effect of almost all air pollutants, which make the indoor air worse.
Symptoms and effects of excess humidity/low indoor air quality
- Irritated eyes, nose, and throat
- Breathing issues Allergies
Increasing humidity level and health risks
The humidity level is increasing globally. Increasing urbanization and industrialization have affected the environment adversely. The environmental factors are becoming less balanced with every passing day. This has caused the need for dehumidifiers to cope with environmental issues.
Humidity can affect your health in more horrible ways than you can imagine, and you won’t even know that its higher humidity level which is affecting your health so badly. Severe allergies, sickness, dizziness, suffocation, respiratory infections, and much more. The regular headache, fatigue, and dizziness will definitely affect your performance for everything you do.
If you or your family members are lazy for nothing, always tired and irritated, the first thing you need to check is your indoor air quality. It might be the reason behind your kids not doing well at study or you are not going well at a job no matter how talented you are.
Depression is the worst thing about improper humidity. if you are feeling sad for nothing and depressed all the time, you are inhaling polluted and highly humid air. There is no need to tell you how bad is depression and how can it end your life within life. It affects your professional life, your family life, your social circle, and your love life (hmmm).
Damp spots are kind of sign of rejection that a place is not worthy to reside. As they say smoke is fire, likewise moist is mold. If you ignore it for long you can observe mold on walls and floor. And at this stage, it is not easy to get rid of it. Why would you wait for the situation to get worse? You are smart enough to take precautions. Aren’t you?
Your health is important
Disease triangle is a very famous term for biologists. It shows how a balanced environment can protect you from pathogens and diseases. And humidity is one of the most important environmental factors.
The environment is a barrier between pathogens and humans. Now it depends on you, that you take it on your side or you leave it for pathogens.
So, the need is clear. We need to get rid of excess humidity.

What should be your checklist when you are about to buy a dehumidifier.
I believe that you deserve the best but the important thing is that you must know what is best. I summarized everything for you, including the technical aspects, reviews, and suggestions. Now you yourself need to know how to make a better choice. Here is the key.
Know your need
The first thing you have to make clear is your need. Dehumidifiers are used at many and many places from the garage to office and form halls to boats. The dehumidifier best for RV cannot work efficiently for the whole home or big bedroom. There are different specifications for different needs. After you have decided on your requirement. Here are the options you should look for:
1. Dehumidifier size compatibility
it entirely depends on the area you need to cover and the environmental conditions.
Here is an approximate analysis of the interrelation between dehumidifier size (water removing capacity per day (pints) and the area that it can cover (square ft):
- Small size dehumidifiers (Best 30 pints dehumidifiers) are suitable for 1500 – 3000 square feet
- Medium size dehumidifiers (Best 50 pints dehumidifiers) are suitable for 3000 – 4500 square feet
- Large size dehumidifiers (Best 70 pints dehumidifiers) are suitable for 4500 – 6000 square feet and above
The moisture level must be considered.
2. Capacity to dehumidify per day
This is the most important thing to check about a dehumidifier. To check on the specified capacity to remove water per day can’t help in all situations. It depends on the conditions in which the dehumidifier is supposed to perform.
Moderately damp (55 t0 64% humidity) = 10 t0 29 pints dehumidifiers (depends on space you want to cover)
very damp (65 t0 79% humidity) = 30 to 49 pints dehumidifiers (depends on space you want to cover)
Wet conditions (80 t0 89% humidity) = 50 to 64 pints dehumidifiers (depends on space you want to cover)
Very wet conditions (90 t0 100% humidity) = 65 to 70 pints dehumidifiers (depends on space you want to cover)
For the area under 300 square Ft with 50 to 54% humidity mini dehumidifiers are best with 06 ounces to 9 pints water removing capacity per day.
3. Dispensing water
The ease of dispensing water matters a lot. Either it is a water tank or it is continuous drainage by hose, it must be easy either way. Now, I tell you what you should check for each of the drainage types.
A. Water tanks
This is an important feature that must not be missed. If you ignore it, it can result in frustration. A good dehumidifier is not supposed to require water dispensing over and over again. You don’t have to rush to empty the water tanks all the time. Capacity does matter to avoid all the mess. Must check the water tank capacity before you buy the one.
It should be compatible with the size of your dehumidifier and its capacity to remove water per day. As the large is a dehumidifier and as the more is its capacity to remove water per day, more should be the capacity of the water tank.
Some dehumidifier brands offer a hose for drainage. But most of the brands have water tanks and just include a point to drain the water through a hose, and the hose isn’t included in the package. But in any case, you should look for quality. Check if the point to attach a hose is durable and if the length of hose is sufficient or not (if the hose is included). you can choose this type of water dispensing if your place allows continuous drainage and you can manage to set a hose.
It is your choice, which option you feel easy for drainage.
4. Energy saving
Bills are a nightmare! Heavy bills sound horrible. So, make sure that your dehumidifier consumes less power. Energy efficiency is included in the product’s specifications of top dehumidifiers, you can check it there. Some brands have an energy star rating. They are proved to consume less power.
Power break isn’t an uncommon thing. It is a great trouble to fix your dehumidifier settings again and again whenever there is a power break. Auto-restart doesn’t make you do this irritating job. This feature enables dehumidifiers to continue previous settings. For dehumidifiers, it is an important feature. Dehumidifiers with this feature will start to work from where they left.
6. Auto shut off
Imagine if the water tanks are full and your dehumidifier doesn’t bother it and keeps on working. What a mess it is. Spills, splashes, and maintenance issues- all in one. Best dehumidifiers shut off automatically when the tanks are full. This feature shuts the device automatically when the water tank reaches its maximum capacity. So, you can dispense the water timely.
Low temperature can freeze the internal units especially when it is about refrigerative dehumidifiers. It is necessary to avoid this situation. This smart feature saves the working units from the effects of low temperature and freezing. Some places, like basements and garages, have low temperature, but high humidity. This feature enables the dehumidifier to work at low temperatures efficiently.
8. Area coverage
Top-rated dehumidifiers mention it in their specifications that how much area can be covered by the product. Choose the one according to your need wisely. Evaluate the area you want to cover and check the area coverage capacity of the dehumidifier.
9. Visible water level
Almost all good brands offer this feature. It must not be a riddle or mystery to know the water level. It is frustrating to check it on again and again for the water level by pulling out the water tank. There must be a visible water level that you can easily get to know when it is time to empty the water tanks, by just having a look at it.
Best dehumidifiers do have this feature. You don’t always have to rush for maintaining your dehumidifier. you don’t have to always think about it. There are many other pretty things to think about. Aren’t there? Dehumidifiers with this feature alert you when it is time to dispense the water or some other maintenance.
11. LED indicators
This is a smart feature for smart people. LED indicators are used to alert you and to inform you about the working status of the dehumidifier.
12. Air filters
Filters save you from allergens and dust. Dehumidification and purification work parallel for the best dehumidifier. Air filters do purify the air. Must check for the filters if your product is good about it or not.
13. Easy maintenance
To deal with your dehumidifier should be fun and must not be frustrating. It must be easy in every aspect. Whatever you are about to do with your dehumidifier, moving it, dispensing water, or cleaning the filter, it all should be as easy as you can imagine.
Noise is a pet issue of dehumidifiers and it is not any less than a nightmare. You don’t invest to get frustrated and irritated. Do you? There are some best dehumidifiers that are good at it. And you should just go to them.
It is the primary matter of concern almost about all electronic devices. You can’t go to buy electronic appliances over and over again. But how can you check reliability? Are you going to buy all dehumidifiers to check which of them will be long-lasting? Or you will trust the company’s claim about reliability? Do you know any company on the face of the earth which says our product is not reliable?
Here come us! You have an option to go through the reviews before you buy to check on the reliability. Our reviews about best dehumidifiers on based on research and experience. All products we mentioned are best for their reliability.
Issues and problems in electronic appliances are very common. You cannot evaluate the reason always. One time some parts are not working and at some other time, the whole device is a failure. Manufacturers should make sure to give a warranty for a reasonable duration so you can feel safe.
17. Portability (Includes space-wise portability)
It is an important feature as we may need to change the place of dehumidifier frequently. Dehumidifiers with wheels are easy to move and maintain. And if you are about to buy a mini dehumidifier, it must be compact and light in weight.
Without handles, it is not easy to maintain or move a dehumidifier. Handles make it easy for you to deal with your dehumidifier either for maintenance or for just changing its place.

It is quite fine. It makes no difference. You can use the same dehumidifiers for the apartment which are recommended for home, without a second thought.
8. What are the various types of dehumidifiers based on applications?
This simply depends on where a dehumidifier is supposed to be used. There are slight variations in the basic model, accordingly.
Basement dehumidifiers are used in the basement area and the main purposes besides dehumidification are to control odor. For certain reasons, they are supposed to have more pint capacity.
Whole-house dehumidifiers work differently. They mostly are connected to the HVAC system of the house. As they have to perform a lot, they are designed to require low maintenance and they are fully automated.
Industrial dehumidifiers are quite large and fully automated. They are designed to require very low maintenance.
RV/ BOAT/Bathroom/ kitchen dehumidifiers are mini in size. They are portable and their pint capacity is mostly not very much high.
9. What is cooling and dehumidification vs heating and dehumidification?
The cooling and dehumidification method includes two parallel processes working at the same time. The air hits the cooling surface, the air is cooled and moisture is removed simultaneously.
This method is one of the most widely used methods to perform dehumidification. Air conditioning appliances work on this principle.
Heating and dehumidification are opposite to cooling and dehumidification, as the name shows. This process works as air is heated and at the same time, water vapors are removed. The air passes through the chemicals which produce heat and absorb the moisture.
10. How can I compare the dehumidifiers?
I have discussed in detail what should be your priorities to buy a dehumidifier. Here I give you tips and a short key for a quick comparison.
Capacity to remove water per day
The quickest and simplest key to choose a dehumidifier is by checking on its capacity to remove water from the air per day. Water removal capacity can be measured in ounces, pints, or liters. It depends on the size of the dehumidifier you are looking for, the are you need to cover, and the humidity level.
It is a must check thing especially if you live in a basement or comparatively damp place, you need your dehumidifier to work 24/7. You have to check for the energy consumption efficiency, if it suits you or not.
10. What are all the benefits I can get by buying a dehumidifier

Industries and need of dehumidifiers
There is a significant industrial importance of dehumidifiers. There is a great number of industries where dehumidifiers are used at various levels; from the very first step to the packaging and storage of final products, to ensure the high quality.
For some industries, it is a must, no matter you care about quality or not. You simply can’t run your industry without dehumidifiers.
1. Product drying
To dry products is a crucial step in the whole process of manufacturing. Improper drying can cause major losses. The food industry, Leather industry, Pharmaceutical industry are some examples among many.
2. Production and processing
Dehumidifiers are used for production and processing in major industries. The automobile industry, healthcare department, food industry, printing, and glass industry do maintain their quality by using dehumidifiers.
The garment industry, fertilizer industry, food industry, and the pharmaceutical industry need to get rid of excess humidity while packaging their products.
Storage necessarily needs dry conditions, no matter it is domestic or commercial. Museums, libraries, shipping, and marine, power industry are some examples.
You must be very familiar with a precautionary statement on so many things you use, which is:
“Always store in a cool and dry place”
You have been reading this all your life on your food items and medicines. Hmmm?
How it can help various industries
1. Food processing industry
This is one of the largest industries and as food is a primary human need, it always will be a major industry.
There is a higher number of foods that are wasted during processing and a great number of difficulties industrialists and workers face in processing due to humidity.
Confectionery foods (Foods that contain sugars) face a great problem due to humidity. It affects the process on various levels. Sugar containing foods are hygroscopic in nature. When the moisture interferes with them, they become sticky with machinery and wrapping material.
It affects product quality too, which includes:
- Change in structure
- The products become grainy and the composition becomes uneven
- Degradation of coating material
- Change in flavor
These problems can be avoided by eliminating the excess humidity. All the steps of production require controlled humidity. In this particular case, even the final product requires the optimum humidity to maintain its structure and quality.
Bakery products face the worst results of fungal activity which is entirely humidity based. Even some hours of exposure to humidity will not leave the bakery products useable. To maintain the optimum humidity for bakery products is unavoidable.
Meat processing is a matter of primary health concern and it needs to be regulated. Humidity creates severe hygiene issues during meat processing. It leaves a bad odor too.
Fungal activity: Each of us is well aware of the link between humidity and the increasing growth of molds and mildews. Fungi is a major food pathogen. The waste of food due to fungal activity is very high.
A dehumidifier can solve these issues
A dehumidifier can solve the issues by maintaining the optimum humidity level during processing, packaging, and storage.
2. Agriculture and humidity
Agriculture is the backbone of the living world. Its importance needs no discussion. And the seed is a primary thing in the whole agricultural field.
I am a biologist and I know the importance of optimum humidity for seeds. Many diseases are seed-borne and annually we face a great loss of seeds as they get wasted. And the one major issue of this waste is humidity and moisture.
A Dehumidifier can help to save the seeds. Keeping an optimum humidity level for seed storage is the best way to deal with it.
3. Electronic Industry
Processing in the electronic industry needs proper environmental conditions. Data analysis shows that half of the product malfunctioning during processing is due to high humidity.
What does humidity do to electronics
- It adversely affects the capacitance of the capacitor
- Damages integrated circuit
- Higher humidity oxygenized CPU
- Interferes with the printed circuit board
- It lowers the working efficiency of quartz devices, liquid crystal devices, infrared and laser devices
A dehumidifier should be used to avoid the losses and to maintain the quality.
4. Chemical industry
Chemicals are extremely sensitive to moisture. I had been working in the lab for 5 years and I saw a number of expensive chemicals changing into granules from powder form. Sometimes it doesn’t remain useable. These bad situations can be avoided by using Dehumidifiers.
5. Pharmaceutical industry
This is the most important industry as it is related to human health. A little negligence can lead to massive losses and regrets. Because this is the hub for medicines and vaccines. This is the source of human health. Ideal standards must be followed in this industry. Environmental conditions have a great effect on medicine. Environmental factors can change the nature of medicine and degrade the active ingredients of the medicine.
You must have known this primary instruction about medicine “keep in a cool and dry place”. Humidity is a primary concern for medicines. Manufacturing and storage both need to be maintained at optimum humidity levels.
Some of the problems this industry can face with excess humidity are:
- Inaccurate results of lab tests
- Raw material deterioration
- Uneven and imbalanced distribution of components
A dehumidifier is a must for the pharmaceutical industry.
6. Paper industry
Paper is very sensitive to humidity. Lithography, flexography, screen printing, textile printing, currency, or any other secure press printing you are working on, the issue will be the same. This also affects the quality of ink on paper due to viscosity and fluidity. Excessive humidity also increases the drying time of ink. The quality can be maintained by maintaining the controlled humidity conditions by using a dehumidifier.
7. Glass industry
The glass needs to be processed very carefully as it is used in a variety of products. Very controlled conditions are required when gluing the glass sheets.
The various effects of humidity on glass manufacturing are:
- Low quality
- End product can’t be attained as required
- Bubbles of steam
- Inconsistent production
These problems can be reduced by controlled humidity levels. And controlled humidity can be attained by the dehumidifier.
8. Plastic industry
Plastics require low humidity in the process of manufacturing. There are many types of plastics which are hygroscopic in nature. They must be kept in low humidity to maintain quality. During the process, plastic injections and blow molding machines are supposed to be dried to work smoothly and for maximum output. The mold is chilled to a very low temperature and then components get the required shape. During this whole process, water vapors from the air can condense on the mold surface. This can result in:
A dehumidifier can deal with these problems by maintaining low humidity levels.
9. Tobacco industry
The tobacco industry is known to be a very sensitive industry regarding humidity.
Effects of humidity can be:
- Microbial growth
- Low quality
- Contamination by insects
A dehumidifier is a need for this industry to avoid losses due to the waste of raw material and low quality.
The growing market of dehumidifiers
The market stats of dehumidifiers are very interesting. Many business authorities are very concerned about it. For sure, a new emerging industry affects the whole market.
The dehumidifiers market segments are:
1. By type
- Refrigerant dehumidifier
- Desiccant dehumidifier
It involves condensation of water
It uses drying substance to absorb moisture
2. By application
Increasing moisture content has made it necessary to use a dehumidifier in industries to maintain quality. In many industries, it is a must while in others it improves quality and reduces losses.
The use of dehumidifiers is increasing at home for healthy and quality living and for comfort as well. The excess humidity at home is a giant problem for a sane human who cares for health and quality living.
Large dehumidifiers are used in commercial buildings. Shopping malls and other commercial buildings are supposed to give a healthy environment to their customers and workers.
This growing need and trend had made this industry a very interesting topic for the business market.
Another interesting fact about the dehumidifier market is its regional split. The market growth to date is not even around the globe. It will dramatically grow when it will hit those regions which are not in the line to date. The regional split is as follow:
a. North America
- The U.S.
- Rest of Europe (RoE)
c. Asia-Pacific (APAC)
- Rest of APAC (RoAPAC)
The reasons for increasing demands
Uncontrolled and unmanaged urbanization has changed the environment drastically. Moisture content in the air is increasing globally. Consequently, impurities, health risks, and suffocation are increasing too. These factors collectively have resulted in an increasing demand for dehumidifiers.
An increasing need for electricity
As the population and industry both are rapidly increasing, the need for power is its peak and increasing day by day. More electricity is required to meet the requirements, and more power plants are needed to establish. These power plants contain expensive equipment. And this equipment is needed to be prevented from corrosion. This includes turbines, boilers, power generators, and condensers. To protect this equipment, dehumidifiers are required necessarily. This is a major factor in the increasing demand for dehumidifiers.
Data analysis shows that the dehumidifier industry will grow by 2 to 5 times more in the coming 5 years. It already has dramatically increased in the last decade. And almost all previous reports from authentic resources, about its growth as an industry by the end of this decade, have been proved to be true.
Competition within the dehumidifier manufacturing industry
As demand has increased, competition has increased as well. Now the manufacturers are focusing on the innovations and pricing to beat their competitors.

New standards to define dehumidifier specifications
There are two certain features on which the specifications are defined
- Capacity to remove water per day (Pints)
- Energy efficiency
Capacity to remove water per day (Pints)
The testing standards for dehumidifiers have been changed since 03-June-2019. Before this date the testing was performed under the conditions: 80°F and 60% RH. But since the testing standards have been changed, now the testing conditions are changed to 65°F and 60% RH. It has changed the Pints/ day quality of all products. Because the same block of air, on a higher temperature, will have more moisture to be removed than at lower temperatures.
Before 03-June-2019, the standard for energy efficiency was the energy factor, but after that, the new energy factor is an integrated energy factor.
The energy factor was the measurement of the amount of humidity removed by dehumidifier per kWh of energy when the dehumidifier is actively working.
While the integrated energy factor depends on three components:
Integrated energy factor= removed water/ energy used+ energy used in standby and other low power modes.
Weather is unpredictable and it is changing continuously. To cope with these changes, first, we need to keep ourselves up to date with current statistics.
The instrument we use to measure humidity is a hygrometer. Humidity sensors measure both: condensation and evaporation.
Two types of humidity sensors are available:
1. Mechanical sensors which are cheaper. These are a little slow. Not as quick as digital sensors.
2. Digital sensors are a little expensive but quick.
How humidity affects other climatic factors being a factor itself
Humidity itself is a climatic factor but it has a strong impact on other factors too.
The cooling effect of humidity manages almost 70% of the average net radiative warming at the surface. There is latent energy in water vapors present in the air. During evaporation or transpiration, the latent heat in the vapors is removed. It causes a cooling effect on the surface of the earth.
Greenhouse gases are permeable to solar energy, and water vapor is the most abundant of all greenhouse gases. These gases capture the infrared energy which otherwise is not supposed to stay on earth as earth emits this energy upward. It is a major contributing factor in continuously rising temperatures.
