But, it can be easily avoided if you use a dehumidifier and tackle the situation. Thus, we have already picked up some of the best crawl space dehumidifiers, which are listed below. But, there are a few things to remember before you pick a crawl space dehumidifier for your home:
Floor Area: All the crawl space dehumidifiers come with a floor area rating that basically tells you how much area is covered by the machine. Depending on the size of the crawl area under your house, you can choose between multiple options ideal for 300 sq. ft. to 8000 sq. ft. Pint Rating: The pint rating associated with the dehumidifiers tells you about how much moisture is being removed by the machine per day. While the entry-level options can remove around 10-50 pints per day, some powerful dehumidifiers are even capable of removing up to 70-200 pints per day easily. Tank Capacity: Most dehumidifiers either use a drain pipe, whereas some have their in-built tanks for storing the wastewater. Hence, if you don’t want to waste time emptying the tank frequently, you should look for an option that has a bigger tank capacity.
Apart from these few factors, there are a few more important things that you should check before buying a crawl space dehumidifier. If you are curious to know, then you should check out the detailed “Buying Guide” that is given below in this article. Now, let’s take a look at the list and help you find the best crawl space dehumidifier.

Buying Guide for the Best Crawl Space Dehumidifiers
Although we have already mentioned so many good dehumidifier options for crawl space in this article for you. If you are buying such a product for the first time, we suggest you go through this detailed buying guide once. This guide will help you know about all the important facts and aspects that an individual should check or consider before buying a new dehumidifier from the market. Hence, without wasting any more time, let’s discuss the considerable things right away.
1. Floor Area
The first thing that you should always check before buying a dehumidifier is the floor area supported by the machine. All the dehumidifiers come with a specific floor area rating like 1500sq.ft., 3000sq.ft., 4500sq.ft., etc. Hence, depending on the area of your house, you should pick the options that can effectively work for your house’s crawl space.
2. Pint Rating
The next thing that you should pay attention to is the Pint rating or the humidity removal rating of the dehumidifier. It is basically the count or measurement of water that a dehumidifier can remove from the air in a whole day. Depending on how worse the situation is, you should pick the dehumidifier for your home. If the environment is too humid, a dehumidifier capable of removing up to 70 pints per day or more is preferable. However, if you are looking for a dehumidifier for casually using indoors, the entry-level options having ratings around 10-50 pints are not a bad choice to pick.
3. Tank Capacity
Since the dehumidifiers take in air and do the job of extracting water from it, the water gets stored into the dehumidifier’s in-built tanks. In that case, once the tank gets full, most dehumidifiers stop working until you empty the tank and pour the water out from it. Well, if the dehumidifier has a small tank, it will fill up faster, and you will have to keep emptying it from time to time. That’s not feasible at all; that’s why you should pick the options that come with a fairly large tank capacity or should have a continuous drainage system so that you don’t have to worry about such things. Generally, the machines with tank capacity more than their humidity removal rating are a good option to pick as the tank won’t get full in an entire day of usage.
4. Controls
Controls and features offered by a dehumidifier are yet another important things to check. Most of the dehumidifiers that are suitable for indoor use come with plenty of controls like humidity control, which allows you to set the dehumidifier to do its job until a designated humidity level is not reached. Apart from that, other features that you can look for are Fan speed, Timer, Auto On/Off features, and more.
5. Fan Speed and Noise
Not all the brands out there mention the fan speed of their dehumidifiers, but it is still a considerable factor to check as it directly corresponds to the noise. It is obvious that a fan running at 150CFM will surely perform better than a 100CFM fan, but it is also true that it will make more noise as well. In case you want to keep the dehumidifier running all day and night, a noisy dehumidifier will not be a good choice to pick. Instead, look for quieter options that have below 40dB or 50dB noise ratings to have the best experience possible.
6. Temperature Limit
Dehumidifiers only work and condense water properly when the temperature conditions are favorable for them. That is why not all the dehumidifiers are the same, and some heavy-duty ones cost so much. All the dehumidifiers have their own operable temperature limits mentioned in the specifications generally. Hence, depending on the environment and climate in your region, you should pick a dehumidifier accordingly.
7. Warranty
In most cases, all the dehumidifier brands out there offer either a 1 year long or 2-year long warranty for their products. However, if you are planning to get a commercial dehumidifier for your home, some brands even offer up to 5-year warranty as well. However, it’s important to check what parts of the dehumidifier are covered under the warranty as some brands offer different warranty periods for different parts like condensers, coils, etc.
