Dehumidifiers are really necessary when you live in a place with high humidity and moisture. Where you can smell the wet odor and you can feel like there is a lot of water in the air around you, that’s when problems occurred. It might be a place with the lack of sunlight or somewhere that’s raining too much.
A dehumidifier will help you to maintain a low level of humidity in the air. Thus, it can protect your furniture, books, or the wall from moisture or worse conditions – mold.

It is important to choose the right Dehumidifier?
Yes, this is really important, I am not kidding. Choosing a Dehumidifier could be more complicated than you thought.
It is kinda like when you are playing a jigsaw puzzle.
If you choose something too big for a humble place, it will be a waste of both electric and efficiency.
Similarly, if you choose something too small for an enormous place, the device will have to run 200% of it’s best and quickly be exhausted.
So how do you know what to choose?
Steps of choosing Dehumidifiers
First of all, you will need to know how big is your place. You can calculate by yourself.
- If you are living in a room with 25 feet in length and 20 feet in width, that would be 500 square feet ( Sq. Ft. )
In case you are living somewhere isn’t using “Feet” but “Meters”, Google can help you to convert. Just type in square feet to m2.
Know about sizes and conditions
When it comes to sizing dehumidifiers or humidifiers, we would consider it with pints.
Yes, we have specific numbers for specific sizes like how tall and how long, but simply pints will do it. Sizes ( or pints ) might make you confused sometimes because there are too many of it. I have been there my friend.
When will I pick 12 pints or when will I need to pick a 20 pints machine? Is it good to buy a 30 pints machine for 500 square feet place?
It’s OK, I’m here to help you with this!
Those are only relative numbers. Let’s get into details. We will split the E.C. into 4 types and 5 convention dimensions.
Four types of Environment Conditions
- Moderately Damp: when the weather is getting humid, you could notice the bad odor and feel a little damp in the air.
- Very Damp: in this condition, you could smell the bad odor and recognize the damp spot with or without a rainy day.
- Wet: bad smell plus water beading on the walls, the floors, and moisture could come in realizing.
- Very wet: damp smell all the time and clear wet signs on your walls.
- 500 Sq. Ft.
- 800~1,000 Sq. Ft.
- 1,400~1,600 Sq. Ft.
- 2,000 Sq. Ft.
- 2,500 Sq. Ft.
Here is a table for you to refer to.
When choosing a dehumidifier you will have to consider both of these, the conditions and dimensions of your place. That will optimize the device’s efficiency, and also your expenses.
What Dehumidifier do you need?
By acknowledged measurements and conditions, you have had all of what you need to choose the right device by yourself. I will do some examples below here.
Presume you are living in a 500 Sq. Ft. place and you can vaguely recognize the damp spot and smell the bad odor, what will you choose? 12 pints Dehumidifier, correct!
Since your place is not too big and very damp, choosing something with more capacity like 25 pints would be a waste and more importantly, it might hurt your beloved wallet.
OK! A second case, what if you are living somewhere with 800 Sq. Ft. with the smell of wet clothes and you can spot water on the walls or the floors. What will you choose here?
You will need to choose something between 500 Sq. Ft. and 1,000 Sq. Ft. here, something between 16 to 20 pints, what it would be?
You can choose the 20 pints here if you are hesitating. Why is this? Isn’t 16 or 17 pints sounds a little more appropriate? Here is the secret.
Choose something a little stronger
I may have said above that if you choose something with more capacity than you need, it might be a waste in many ways. Don’t get me wrong, this is still right with a mere little difference.
For example, when you only need something about 12 pints, but eventually you bought a 24 pints machine. Double the capacity, that is wasted!
But when you need something about 22 or 23 at it’s best, you can choose something with a little higher capacity, a 26 pints Dehumidifier if you can afford it. I will give out 2 reasons for you to understand why this is better.
Firstly, it will make sure your problem with humidity will be solved completely because of the outstanding performance.
Secondly, and this is critical, it will help your device to run more “comfortably”. In other words, it can make sure your device would never have to reach its maximum limit.
Like when you are doing something which you don’t need to use all of your resources to resolve it, right? You will have time to let your brain relax thus saving more energy.
Refrigerant for hotter and Desiccant for cooler
After have known all about dimensions, environment conditions, now you are being able to choose a size by yourself.
However, you need to know a few more things, which are two basic types of Dehumidifiers: Refrigerant and Desiccant.
So what are the differences between these two?
If you are living somewhere continuously getting hot or humid, the Refrigerant type would be more suitable since it works better when the temperature is higher than 65 °F (18 °C).
This type of Dehumidifier works the same way as an air conditioner, using a fan to draw moisture from the air through a coil, warms it and then releases it back to the room.
Problems will occur if the temperature drops below that threshold, in which you may find the coils getting iced and preventing the whole thing from functioning decently. This type of machine also produces noise while they are running.
Desiccant type is basically the opposite to the Refrigerant. It will function more efficiently while the temperature falls below 65 °F (18 °C).
And its operation will be quieter compared to the counterpart.
Miniature and Whole-house Dehumidifier
That is all the basic information you need to know about Dehumidifier sizes. So now, what will you choose when your place is more than 2,500 Sq. Ft, or let’s say 3,000 Sq. Ft?
If you want only one machine to cover all your house, we got it.
Only one Whole-house Dehumidifier in the basement will help you to reduce humidity in all of your rooms. That will help you save more money later despite the fact it is more expensive in the beginning.
Besides industrial sizes Dehumidifier listed above, Miniature or Portable Dehumidifier is what you need for a small place only. Like your own room ( about 210 Sq. Ft. – 20 square meters ), etc.
The miniature type is much more convenient, saving you more space since it is only approximate to a shoe. It is ultimately portable, which means you can hold it with only one hand and carry it around your home or use it for different rooms.
So let’s conclude what we have learned here.
First of all, the steps of choosing a Dehumidifier:
- Measuring your dimensions.
- Figuring out your place’s condition.
- Using that information to decide what size would fit your place best ( remember the trick – choose something a little stronger ).
After that, consider whether you need a Refrigerant type of Dehumidifier ( for hot places ) or Desiccant one ( for those cooler ).
In other cases, you can:
Buy a Whole-house Dehumidifier if you only want one to cover all your house and save money in the long run.
Choose a Miniature Dehumidifier in case you need something handy, something can save you space, or something for your private room only.
