What Size Dehumidifier Do I Need?

Dehumidifiers take excess moisture and humidity to bring the level of moisture in the air to the normal level. People buy dehumidifiers, but most of the time, they fetch the wrong size of the dehumidifier and waste the money. Before investing in dehumidifiers, it is essential to check the size of the dehumidifier you need according to the room space, as it could be the basement, small rooms, etc.

Here is the guide to help you choose the dehumidifier that would work for the required space rather than taking a cumbersome machine to your house with no efficient results.

How Are Dehumidifiers Sized?

Dehumidifiers are sized based on the moisture capacity they can suck in from room or space. And in terms of dehumidifier, there are a certain amount of pints that a dehumidifier can remove from the air in the total time period of 24 hours. The pints per day or PPD will help you choose the right dehumidifier for yourself.

Another factor that is important while buying the dehumidifier is the square footage of the dehumidifier and the area required. This way, you will get the right size of dehumidifier without any problems.


The Ideal Size of Dehumidifiers

As the dehumidifiers are based on the amounts of pints they can remove, the ideal size of the dehumidifiers come in the capacity of models that can remove the pints of 30, 50, and 70 within 24 hours. However, if you need a smaller dehumidifier, the least you can get is 20 pints, and the most you can get is the model with a capacity of 100 pints a day.

Here is the size chart of dehumidifiers that would help you get an ideal dehumidifier size for the required space.

Conditions 300 – 500 Sq.Ft. 700 – 1,000 Sq.Ft. 1,500 – 2,500 Sq.Ft.

Dehumidifiers for the large Space More Than 2500 Square Ft.

Whole House dehumidifier

Some people buy dehumidifiers only for one specific room. But if you want to move your dehumidifier from one room to another, then it is recommended to measure the largest area and buy a dehumidifier according to that.

However, if you are looking for a dehumidifier that can work in several rooms when needed, the Whole-House Dehumidifier would be the best option for you. Whole-house dehumidifiers might not be portable, but they work with excellence and benefit long-run usage.

The whole-house dehumidifiers are ducted to the systems of Heating, Ventilation, and Air conditioning in your house, and they dehumidify the air before it starts to enter the house.

Whole-house dehumidifiers can work best for up to 3000 square feet or even more than that. Another plus point of these dehumidifiers is that they help increase the AC cooling as it becomes easier for Air conditioners to dry the cool air.


Dehumidifiers for the Small Space Ranging From 100 To 250 Square Feet

Needless to say, it would be difficult to adjust dehumidifiers of 70 pints in a small room. Therefore, it is better to buy the Mini Dehumidifier. Mini dehumidifiers can work within the space of 100 to 300 max. square feet.

The usage of the Mini dehumidifiers is for the small rooms, babies’ rooms, and nurseries. An important factor to consider for the mini dehumidifiers is that they do not have large reservoirs, and hence there is the option of auto-shutoff. The auto-shutoff function works when the reservoirs fill up to the maxim limit.


Desiccant Dehumidifiers

Desiccant Dehumidifiers working principle

If you live in an environment where the temperature is relatively colder, then you might have heard not to buy the dehumidifier. The reason is that refrigerant dehumidifiers can stop working in colder environments as the coils can start to freeze.

To rescue this problem, desiccant dehumidifiers step in. The working of the desiccant dehumidifier is described as it is positioned with the rotor filler sheets made of desiccant material. Desiccant dehumidifier absorbs the air, and the moisture passes through the rotor – the place where humidity gets absorbed.

They do not have a compressor, and they do not produce noise. They are highly efficient in working.


10-20 Pint Dehumidifier

10-20 pint dehumidifier models are best for the smaller spaces that range from 500 square feet to 1000 square feet. You will have no problem placing them, and their usage will be smooth and work efficiently for such spaces.


30-pint Dehumidifier

If the space is moderately damped, then a 30-pint dehumidifier would work perfectly fine. 30-pint dehumidifiers are suitable for 1000 square feet to 3000 square feet.


50-70 Pint Dehumidifiers

If you notice a high ratio of moisture or humidity in your room, you will need a large dehumidifier with a high amount of pints to remove the access of water from the air. For a space with an area ranging from 1000 square feet to 2500 square feet, the 70 pints dehumidifier would be ideal. Whereas, for the areas smaller than 1000 square feet, 50 pints or even 30 pints dehumidifier would be the most suitable option.

They can be noisy, but they will helo you give healthy air with no excess moisture or humidity.


Conclusion

Dehumidifiers should be chosen according to the area and required amount of moisture. You can measure the percentage of humidity in the area to have the correct amount before purchasing and making a decision. Besides that, measure the area of your room correctly to avoid the wrong purchase in the pints of dehumidifiers. This guide to choosing a dehumidifier will help you make the right decision by your needs.
