While I love living in an area where it is hot for the majority of the year, the truth is that the humidity can be a bit overwhelming at times. Outdoors it can be quite oppressive, so I head indoors to get away from it only to find that it is just as humid inside as it was outdoors. It is a tale I am sure that many of you can tell. Even if you don’t live in climate where it gets particularly humid, the so called dry heat, that does not meant the humidity cannot still build up in your home. Moisture can get into the air in a variety of ways, making it humid and difficult to enjoy the sanctity of your house.

However, it is not one that cannot be resolved.

It is the kind of smart decision that any home owner or renter should make, even if you are looking for a cheap humidifier as your option.

Why Should You Trust Us?

There is no doubt that you have read hundreds of reviews on virtually any product or service which assure you that they are the authority you can trust? You probably look at that wondering, “Really? What makes them so trustworthy?”

That is a good question and one we would not blame you for asking in relation to this review as well. You want to know that the information you are receiving is trustworthy, and we want you to have that piece of mind. So here is what you should know about us.

Trusting the review of any product or service on the internet can be a difficult one to say the least. You want to be sure that you can trust the authoritative, unbiased opinion of the reviews you are reading.

First off, we are not paid by any company or organization that designs, creates, or sells these humidifiers. While you may find links to the products, that is for convenience only and is not an endorsement because they paid us to endorse it.

Secondly, we have done extensive research to complete this review. We didn’t just want to find the best 30 pint humidifier. Our researchers have evaluated all of the top products, examining not only how efficiently they worked, but finding what is the top rated 30 pint dehumidifier and how well they will work in different conditions in a home. The result has been an evaluation that will help you to know what is the best 30 pint dehumidifier that is also a cheap dehumidifier without operating like it is cheap.

How to Determine the Right Dehumidifier Capacity

Dehumidifier capacity refers to the amount of moisture that a dehumidifier is capable of removing from the air in a room. It is determined by room size and humidity levels.

Let’s say I have a 500 sq. ft. (46.45 sq. m) room with moderate dampness. My dehumidifier must have a capacity of 10 pints (4.73 L) of water per day. For rooms that are larger than 500 square meters, I will simply add 4 pints (1.89 L) for each additional 500 sq. ft. of space. For example, a 1500 sq. ft. (139.35 sq. m) room would require a dehumidifier that can eliminates 18 pints of water per day.

However, for extremely damp conditions and very wet humidity conditions, different capacities apply. I would need a dehumidifier with capacity of 12 pints (5.67 L) for a 500 sq. ft. room that is very damp. The capacity should increase by 5 pints for each additional 500 sq. ft. of space.

For very wet humidity conditions, I would need a 16 pint dehumidifier for 500 sq. ft. of space. For bigger rooms, just add 6 pints (2.83 L) for each additional 500 sq. ft. room space.

Now that you know what is the right pint capacity of the dehumidifier you are going to purchase, you can consider having a look on our reviews of other dehumidifiers depending on your requirements. In this article, we will be only reviewing top five 30 pint dehumidifiers:

What is my recommended ACH & CFM?

ACH, or Air Changes per Hour tells you how many times the air enters and exits the room through your dehumidifier in an hour. It tells you how many times the room fills up with air in the span of one hour. ACH is important in deciding how much airflow is needed in order to dehumidify a room.

An extremely wet room would have puddles or standing water inside, and requires an ACH of 6. A wet room with humidity level of 80-90% will show signs of mildew, mold, and wet spots. The recommended ACH for this is 5.

If your room is very damp, has a humidity level of 70-80% with visible damp spots and mildew smell, you need an ACH of 4.

Lastly, if your room smells musty and feels damp in humid weather and has a humidity level of 60-70%, you need an ACH of 3 for such rooms.

Now, how do you compute the CFM (Cubic Feet per Minute) needed to dehumidify the room? To do this, first multiply the cubic square footage of the room (l x w x h) by the ACH value. Divide that number by 60(minutes) and you come up with the recommended CFM.

What Is a 30 Pint Dehumidifier?

You may be sold on the idea of reducing the humidity in your home, but aren’t exactly sure what a 30 pint dehumidifier exactly is. This is nothing more than a device that absorbs 30 pints of water at a time before it is full and needs to be emptied. Depending upon the area that it has to cover, these humidifiers may require that you empty them once or twice a day or as infrequently as once or twice a week. It just depends upon where you live and how much space it needs to dehumidify.

What makes a 30 pint room dehumidifier option better than the standard 50 pint option is that it is portable. This makes it more lightweight, allowing you to move it if necessary or to simply put it aside if it not needed. Most come with wheels, making the process of moving it a whole lot easier.

Because of its smaller reservoir, this becomes the ideal appliance as a small room dehumidifier or one that works best in an area that does not have an excessive amount of humidity. While they have the power and efficiency to work in any space, you must understand that if you are asking them to take on a heavier load, which will mean that you will have to empty the reservoir more often because they do not have a direct drain like the larger options do. Again, this is not a problem if you are willing to do so.

How to Find the Best 30 Pint Dehumidifier for You?

Before discussing the top rated 30 pint dehumidifiers, it is important for you to have some idea of what makes a great room dehumidifier for you to buy. As you have seen, the size of the room you are intending to use it in plays a significant role in your selection. If the humidity level is extremely high, you may find that it has problems handling the heavy amount of moisture, and the process may not work as well. However, if you are looking for a small room dehumidifier then these are the perfect options, because they can handle even a heavy load.

It is also important to keep in mind the inside temperature when making your decision on the best cheap dehumidifier for you. Many of the small dehumidifiers that you will find in this class of appliances have minimal ability in terms of controlling the temperature of the room. They simply rely on your normal air conditioner or the air temperature that is in the room already, meaning that it may not get much cooler in the room even when using the dehumidifier. This is important because if you are placing the dehumidifier in the much cooler room, like a garage or basement, when it is much cooler then the coils may actually freeze up and the appliance will not work.

Things to Consider When Choosing a 30 Pint Dehumidifier

If you are going to find the best dehumidifier for yourself, there are certain things you want to take into consideration that can help you find a cheap dehumidifier that is also one you can depend upon. Here are some things you want to consider when making your selection.

Ensuring that you get the most value for your buck is an important part of any purchase, and this is why you want to get as many features that enhance the use of the purchase as possible.

Easy to Use Controls

we live in an extremely technological society, but the controls to that appliance aren’t always easy to use. This can be true of your dehumidifier as well. There are those that are easy to use, including allowing you to set the level of humidity you wish to achieve in a room. Some may think that removing all humidity is a good thing, but the truth is that moisture in the air can be good.

Too much dryness can lead to nose bleeds and irritated skin, so keeping moisture in the air is beneficial. Finding an easy to use small dehumidifier that allows you to set the percentage of moisture should be something that you consider.

Automatic Restart

This is an important feature in a dehumidifier because you may have a situation where the power goes out in your home, allowing moisture to build up quickly. When this happens many dehumidifiers that you find will simply shut off and not come back on once the power is restored. This can allow your home to become humid quickly, so finding an appliance that automatically comes back on when the power is restored is a great feature you may want to consider.

Frost sensors

we mentioned in this article that you may place your appliance in an area where it can be quite cold. This can cause the coils to become frozen so that the dehumidifier will not work. This may not be the only problem however. You may have freezing in the reservoir or the drainage hoses which can cause damage or at least stoppage.

There are dehumidifiers that have sensors that inform you if an issue like this arises. If you are going to use your appliance in an area where frost could occur, this may be something you want to make sure you consider when making your decision.
