A dehumidifier is an important entity that saves your basement and households from a variety of diseases, therefore, purchasing a dehumidifier for the basement of your house requires a keen approach. Otherwise, you will end up buying a product which would not satisfy you completely. We hope that you will find this list of FAQs helpful and effective when you go shopping.
Features to consider while choosing a dehumidifier for basement
There are certain things that you must give a good look upon before going for the purchase of your basement's dehumidifier. It is advised to choose the idlest one after taking all your requirements into account. As per our approach, we found following points that you should check before buying a dehumidifier for household purposes.
One of the most important features that you should emphasize upon on your purchase is the area of the dehumidifier’s coverage. The reason behind this is that if you don't buy the right product according to the requirement, it will not be as effective as you want it to be. Suppose, you bought a dehumidifier which is suitable for an area of 2,200 square feet, such as the AlorAir Basement/Crawlspace Dehumidifier, for a basement of a total area making up to 3,000 square feet, the only thing that will happen is dissatisfaction. The same concept goes for choosing an overpowered dehumidifier, as it will consume much more electricity than any relevant product.
Dehumidification performance is the numerical variable used to define the amount of moisture a dehumidifier will reduce in a certain period of time. You should choose the idol model by checking if the product meets your requirement or not. Suppose your basement is sadly cursed with very high moisture level all the time, you should be going for a dehumidifier which can reduce a high amount of moisture in a day. So, if you have the same issue, you should go for the heavy machines such as the Ivation 70 Pint Energy Star Dehumidifier.
Another important aspect that you should check while purchasing a dehumidifier is an inbuilt pump. Pump serves as a great ally of your dehumidifier as it saves you from the trouble of running to the basement several times a day to drain the water. Not many dehumidifiers are in the market that offer an inbuilt pump setup. So, this is the part where AlorAir Basement/Crawlspace Dehumidifier again excels in our list of the best dehumidifiers for a basement.
Water tank capacity
If you are also a part of this era's hectic culture then choosing a dehumidifier with a large water tank capacity is quintessential. The purpose of this water tank is to store off the collected moisture of the basement's surrounding in the form of water. Some dehumidifiers come with small water tanks while some of them are huge, like the Tosot 50 Pint Dehumidifier, so you have to make the right decision as per your requirement. For those who have an outlet in the basement that they can use as the way to transfer the collected water in the drainage, you can go for both the small and the medium tank capacity dehumidifiers. But, in the opposite case where you do not have the liberty to use any outlet then you should choose a dehumidifier with large water tank capacity such as. This will save quite some time as you would not have to come running multiple times every day, all the way to your basement to drain the water bucket.
When you are in the market in search of a dehumidifier, you will find a large variety of products that will come with multiple settings options such as, working modes and collection speed. This is the time when the customers get into the dilemma. So, choose the product as per your needs. Normally, two or three settings are allowing you to choose the exact speed.
Continuous drain option
For those of you who want their dehumidifiers to work constantly all the time, it is better to choose one with the continuous drain option, such as the Tosot 50 Pint Dehumidifier or the AlorAir Basement/Crawlspace Dehumidifier. This feature allows a flow of water to leave the dehumidifier module on a constant basis. Such models come with a drainage hole on the bottom of their water tank. This is a great feature which is quite handy for those who have a drainage outlet available in the basement area.
Dimensions and weight
Whenever you buy any item for your household, product's dimensions and weight play a critical role in the purchase. In the case of dehumidifiers, this aspect becomes more important as you might use dehumidifiers in your basement as well as other places too. So, choosing one with better mobility might be a great asset for you. So, before the final purchase, you should check the dimensions and weights of the product and go as per your availability. For instance, if you’re searching for a very compact model to use in a small basement, go for the Gurin Thermo-Electric Dehumidifier.
One thing that might not affect you immediately but offers great significance in the long run is the warranty of the dehumidifier. Some people consider this as a deal breaker.
Dehumidifiers like AlorAir Basement/Crawlspace Dehumidifier might be a great pick if you are looking for the best dehumidifier with an extended warranty.
These days dehumidifiers come with a variety of inbuilt features which you should give an emphasis upon:
LED / LCD indicators: Some dehumidifiers come with an LCD display of all the functions and stats related to the product while some of them are represented in the form of LED indicators. LCD displays are more compact and easy to access as compared to LED indicators. LCD displays the stats which a user can read without any prevalent know-how. But, LED indicators offer information with a variety of blipping pattern. LED dehumidifiers are relatively cheap than those with LCD panels.
Defrost: Some of the dehumidifiers for basement come with an auto defrost module while others have regular defrost modules. The difference between the two should be judged according to your basement’s regular temperature. If your basement has a pretty low temperature, then you should go for a dehumidifier with auto defrost. But, if your basement is not that cool on a regular basis then even a manual defrost module enabled dehumidifier will work just fine.
Auto shut-off: Power consumption is the very first thing that comes to our mind when we go for the purchase of any electronic product. Dehumidifiers that come with an auto shut-off feature are very efficient as the user can set the base value of auto start and once the basement's humidity reaches to that level the machine will start automatically. So, it saves the energy that might have been wasted for using it at times when humidity is quite low. Also, this feature adds some peace of mind regarding possible leakage when you don’t use the continuous drainage option: the unit will shut down when the water tank is full.
Tips on how to keep your basement mold-free
Molds can cause serious health issues, including the black mold. Basements are the most neglected part of a household. Thus, the chances of moisture boosting up the creation of molds in the basement area are a real threat, both to health and your house. You can follow these tips to keep your basement mold-free:
- Monitoring the level of humidity in the basement area on a regular basis will help you to act on the situation before the mold formation starts.
- Try not to grow the plant indoors as they are very efficient in making the environment cool which is an excellent source of moisture formation.
- Stop storing wood or any similar type of thing in the basement.
- Reduce the congestion of the basement region and make sure that the water is directed away from your household.
- Use an effective dehumidifier which you should purchase as per the necessity.
- Try to drain the water reservoir bucket of your dehumidifier's tank to let the machine work regularly.
While placing a dehumidifier in a basement, you should keep in mind that you leave 12 inches of spaces on all the four sides of the machine. This is necessary because a constant airflow is required for the effective operation. Another important concept that you should know about the placement of a dehumidifier is that moisture level changes from room to room and even in different parts of the basement. So, instead of installing a dehumidifier in the area where the density of moisture is low, you should place it in the region where moisture density is at its peak.
People usually are attracted to the myth that running dehumidifiers on a higher or maximum speed makes the moisture removal process very fast. If you’re not in a hurry, and use your dehumidifier regularly, running it at a lower speed doesn’t mean it won’t cope with its job. Although, increasing the speed might make the process a little faster, and may come in handy if you, for instance, need to leave your house soon, but keep in mind that the energy consumption will increase that way, overall not making your energy bills any lower.
Most of the dehumidifiers on the market come with LCD or LED indicators. They indicate you about the stats related to humidity. For manual shutdowns, you should wait till the humidity level hits the 35% mark as it is safe and efficient to turn off the dehumidifier then.
Dehumidifiers come with a variety of features and modes, and here are the three that impressed us most of all.
Dehumidification performance is the crucial feature when it comes to the unit’s overall effectiveness evaluation. So, this makes the Tosot 50 Pint Dehumidifier the best dehumidifier for basement mold, in our opinion. It excels in almost every category as it has a coverage area of up to 3,000 square feet, the dehumidification performance of 50 pints a day and the water reservoir capacity of two gallons.
Water tank storage capacity plays a great role in the overall effectiveness, and thus, the AlorAir Basement/Crawlspace Dehumidifier is the second best-rated dehumidifier for the basement as it offers a spacious water tank of 16 ounces.
Whereas, the best ratio when it comes to dimensions and product’s effectiveness, Gurin Thermo-Electric Dehumidifier is the perfect fit for the title of the best portable dehumidifier for a small basement and is also our budget pick. It offers almost all the features that are required, and all of them are combined in a compact design.
