None of us view our homes as places where danger lurks, especially when it comes to our well-being and health. Unfortunately, things aren’t usually as perfect as they seem, especially when people don’t take proper precautionary measures. A problem that even the most luxurious of homes can be confronted with is the appearance of mold and mildew. These pesky guests appear in conditions of high humidity, the excess moisture in the air favoring their growth.
What this amazing household appliance does is it removes the moisture from the air until it reaches normal, healthy levels. In every room of the house, the perfect humidity that must be kept for the health of the inhabitants to be protected is between 30 and 50 percent. Anything higher than this causes a chain of bad reactions, even the construction of the house and the electronics being severely damaged. Therefore, in order to keep the problems that accompany high humidity levels at bay, you must use a great performing model.
They come in different types based on the technology they use. The most popular one is the refrigerant type that absorbs the air, sends it through a cooling chamber that turns the water vapors into liquid, then releases dry air back into the room. These units are easy to use and deliver the highest performance in removing excess air moisture. The second type is the desiccant that uses a desiccant agent like silica gel to absorb and retain moisture from the air. This type is the second most popular, with a satisfying performance in dealing with high levels of moisture. The third and least common type is the ventilating that simply pushes dry air into the room through a vent in order to increase air circulation. This is the simplest type and the least effective as well.
The refrigerant type uses basically process as the refrigerator does, cooling a metal plate that the moisture from the air condenses on. This type of unit features a fan that draws the air in the room through the device and over the plate, the moisture condensing on it and dripping into the reservoir or water tank. Generally, these dehumidification devices enter the standby mode when a normal humidity level indoors is met, reactivating when it is required again. They are the most effective when used in rooms that have normal temperatures, not being great choices for those who want to place them in cooler areas like the basement. The reason why they’re not recommended in these situations is that ice forms on the coils, drastically lowering the performance of these appliances.
Desiccant units absorb the excess moisture from the air with the help of a wheel that consists largely of desiccant material that turns slowly through the stream of air. While the rotation cycle takes place, a part of the wheel passes through a stream of warm air, reactivating the desiccant through driving off the moisture. The condensed water is then collected in the water tank or reservoir, or it’s automatically drained via a tube if you go with this option. The perk of going with a desiccant model is the fact that it can operate at lower temperatures when compared to refrigerant units, thus being a good choice even for the basement.
Whole house ventilation units are widely considered as being the most effective when it comes to clearing the excess moisture in damp, moldy areas, eliminating condensation. They are generally cheaper to run when compared to plug-in units, and they produce such a low noise that you’re very likely to forget that you have installed them. They work by pushing the air from the location where they’re installed down into the house through a grill that is mounted usually in the hallway, new air constantly arriving in all the rooms.
A humid air is usually harder to inhale because of the water vapors that make it feel very heavy. Also, air humidity is very dangerous for the safety of your lungs because it can be the cause of various breathing illnesses like asthma, allergies, or bronchitis. Therefore, if you can’t breathe well, if your sleep is disrupted by coughing, or if you struggle with allergies and you are not aware of the cause, it might be the air humidity.
An increased level of air humidity is also related to how hot your home feels, especially during the hot season. Usually, a moist air tends to feel a degree or two hotter than it really is, which might make you want to turn on the AC more often. If the temperature doesn’t drop even though you cool your house, it might be the air humidity.
Without a doubt, mold and mildew are the clearest signs that you need to lower air humidity. Mold spores travel by the water vapors in the air and they are often very hard to get rid of as they are constantly favored by air moisture. In case you have done your best in ridding your home of mold but it still manages to reappear, it might be the air humidity.
In some occasions, the water vapors in the air are cooled and turned into condense that can be seen on windows. This problem can be encountered in the kitchen or in the bathroom and tends to happen more often in the cold season when the differences in temperature are higher. If you get condense on the windows all the time despite the fact you eliminate steam sources, it might be the air humidity.
By cleaning the appliance regularly, you prevent great damage from being done to it as build-up can easily develop in a dehumidifier. There are two parts of the appliance that must be cleaned on a regular basis, more precisely the water collection tank and the air intake and exhaust grills. To clean the water collection tank, you must use a disinfectant or soapy warm water. This procedure needs to be performed once per month at least as mold and mildew can build up quickly into the tank. The air intake and the exhaust grills must be cleaned once per season with a vacuum that has a brush attached to it, thus getting rid of dust and debris that build up and that create blockages.
As we have already said, there’s little maintenance work to do with this household appliance. What you need to do is to replace the filter of the appliance as often as instructed in the user manual that it comes with. The air filter that the unit comes with has the role to clear dust and allergens from the air, so it will inevitably become a danger if it’s not replaced, destroying the air’s quality instead of improving it. Also, make sure that you avoid turning it off and on too quickly as this may cause the unit to overheat. What you should do is to let it cool for 10 minutes before you turn it back on, thus allowing the pressure to be equalized.
First and foremost, these products are mandatory to have around because they prevent the appearance of mold and mildew. Seeing how they decrease the levels of moisture, both mold and mildew thriving in conditions of excess moisture, they create an incompatible growth environment for them. This is especially important when it comes to spaces that tend to have big problems with humidity like basements, for example. Therefore, with the simple addition of the device in this area of your home, you won’t have to worry that you might be confronted with mold and mildew.
Dust mites are more common than we’d like to admit, and they present a great danger for those who suffer from allergies, being triggers for many people. No matter how clean you think your home is, dust mites are surely inhabiting it, lurking in the carpets, mattresses, and upholstery. To get rid of these microscopic pests that cause unpleasant side effect to those who are allergy sufferers, you have to lower air moisture. The reason why this device is a great choice for combating dust mites is that it removes the moisture that they thrive in. Therefore, due to the fact that the environment won’t be humid and prolific for the dust mite population anymore, it will be severely reduced.
If you are faced with an unpleasant musty smell in certain areas of your home, you will notice that no matter how much you clean it, the odor still won’t go away. The reason why this happens is that the smell actually accompanies mold and mildew. Therefore, the only way to actually get rid of it is to clean the area affected by mold and mildew with a mixture made from vinegar and water and do everything in your power to prevent them from appearing ever again. Of course, for this to happen, you need to place a dehumidifier that can handle the job in that specific area that usually has problems with high humidity.
The electronics and tools that lay around our homes are huge investments that we care for and that we have to protect them to last for as long as possible. Unfortunately, this won’t be possible in a humid environment, electronics and tools eventually getting corroded if they’re not kept in the best of conditions. But with the help of a device that reduces air humidity, this won’t be an issue of worry for you because these items are going to be kept in perfect humidity conditions.
If you don’t own a drying machine and the weather outside doesn’t allow you to hang dry the clothes that you have washed, you will inevitably have to put them indoors to dry them. But the problem is that a humid environment doesn’t favor this process, prolonging it more than it’s needed. Therefore, you have to place an air de-moisturizer in the laundry room or wherever you hang dry your clothes. Also, the appliance should be present in the room where you dry the clothes because excess moisture will appear immediately as they start to dry, favoring the appearance of mold.
It might not make any sense at first, but this product can actually help lower energy costs. Yes, you will have an additional appliance that runs whenever it’s needed in order to reduce humidity levels, but it will actually help when it comes to the electric bills because it is going to help the air conditioner be more efficient. When the air is humid and hot, the air conditioner will have to operate more intensely in order to remove moisture and cool the environment. On the other hand, if this device already handles removing the moisture, the air conditioner will only focus on cooling the room.
For this step, you can either use a hygrometer or you can determine the humidity levels on your own by analyzing the rooms in your home. If you have a hygrometer, use the device to find out the percentage of humidity in every room of your house. In places where the humidity exceeds 50 percent, it’s clear that you need some help. In case you don’t have a hygrometer at your disposal, pay attention to certain details to figure out what levels of humidity you are confronted with. If the room contains small puddles of water, humidity is between 90 and 100 percent in it. If there is mold or mildew in the area, and the air feels and smells wet, the levels are between 80 and 90 percent. If the air simply feels damp and you recognize the smell of mold and mildew, the levels are between 70 and 80 percent. If the humidity levels are between 60 and 70 percent, the air in the room will smell a tad musty and it will feel slightly damp.
In case the humidity levels are between 90 and 100 percent, you need to make 6 air changes per hour. If it’s between 80 and 90 percent, you need to make 5 air changes per hour. If the levels are between 70 and 80 percent, it’s required to make 4 air changes per hour. Last but not least, if humidity levels are between 60 and 70 percent, 3 air changes per hour are necessary to get rid of the excess moisture.
If you don’t already know what is the size of the room where you’re dealing with excess moisture, you can determine it on your own with a simple calculation. First, you need a tape measure that you will use to measure the length and width of the room. Afterward, you simply have to multiply the values of the length and the width to figure out the square footage of this area.
To determine the air flow that you need the device to feature in order to dehumidify the room, you first have to determine the cubic feet in the room. To figure out the cubic feet, simply measure the height of the room, and multiply that value by the square feet. Now that you know how many cubic feet are in it, multiply them by the number of air changes per hour. Next, divide that value by 60 to obtain the amount of air flow.
Last but not least, before proceeding to buy a certain model, you have to figure out the pints of moisture that have to be extracted from the room on a daily basis. For humidity levels between 60 and 70 percent, you need one that can extract 10 pints of moisture within 500 square feet. For every additional 500 square feet, add 4 more pints. If the levels are between 70 and 80 percent, go with a model that can extract 12 pints of moisture daily from a 500 square feet area. For every extra 500 square feet, don’t forget to add another 5 pints. If the humidity is between 80 and 90 percent, go with one that collects 14 pints within 500 square feet, adding another 6 pints for every extra 500 square feet. If the area has humidity levels between 90 and 100, choose a model that collects 16 pints over a 24-hour period within 500 square feet, adding 7 pints for every additional 500 square feet.
First of all, you have to make sure that the model you lay your eyes on is capable of effectively handling the moisture levels of the room that you want to place it in. Therefore, your first worry will be to match the size of the product to the humidity levels. What we recommend you do and what we view as being the best choice is for you to go with a model that has a generous dehumidification capacity of 70 pints per day. This is the ideal capacity because it shows that it will be able to effectively remove moisture no matter how humid the environment is.
One of the features that influence the efficiency is the humidistat that enables it to detect the air humidity and adjust its operating according to the ambient requirements. A model that displays the actual humidity level and lets you select the level which you aim to reach will deliver a better performance at a lower running cost. This guarantees that it will work until it reaches the desired and optimal humidity level.
All products of this kind feature a collection reservoir where the moisture that they remove from the air is stored. When the reservoir is filled, it generally shuts off until the reservoir will be emptied in order to continue to operate. For some, this is extremely bothersome because they are confronted with dangerously humid spaces from where it will gather a lot of moisture fast, meaning that they have to waste a lot of time emptying the reservoirs. This is the reason why the continuous drain option is of a great importance, taking this worry off of the user’s mind. What this option represents is the possibility for a hose to be attached to a drain spot, allowing the moisture that is gathered to be released directly and continuously.
The timer feature is more important than you can imagine with these devices, allowing the user to establish in advance for how long the unit should operate. Generally, for the top of the line models, the timer can be set to a maximum of 24 hours. By going with a model that has this important feature, you don’t need to worry that it will operate for more than it’s actually needed, lowering the costs on the electric bill by doing this.
Energy efficiency is worth taking into consideration when purchasing a device that runs on electricity because it prevents high costs on the electric bill. For the model that you choose to be energy efficient and its operation to not cost you too much money, make sure that it comes with the Energy Star certification. As you have probably already noticed from our comparison table of the best performing models out there, they all come with the Energy Star certification.

First of all, we made it mandatory for all of the top quality models that we have reviewed and ranked to have the impressive dehumidification capacity of 70 pints over a 24-hour period of time. This way no matter how humid is the area where you will use any of them, these products will be able to effectively and efficiently lower the moisture.
The relative humidity range is another important rating criteria that we took into consideration because it shows the level of humidity that can be set to maintain. Our top pick, the Frigidaire FFAD7033R1, boasts an impressive relative humidity range of 35%-85%, meaning that it allows the user to set the humidity desired for the room it’s placed in anywhere between these levels.
Knowing that the air flow is one of the most important stats, we have made sure to rank the models in our top according to this aspect as well. Of course, we couldn’t overlook the impressive 280 cubic feet per minute air flow of the SPT SD-72PE model, a dehumidifier that is guaranteed to dehumidify the area it’s placed in fast and without encountering any problems.
The dehumidification area shows how many square feet that the model is designed to perform at its highest in. The bigger the area, the better especially for those who need to dehumidify large spaces like basements. The models on our list that score the highest from this point of view are the Whynter RPD-711DWP and the Keystone KSTAD70B, both of them being capable of handling a large dehumidification area of 4500 square feet.
A humidistat is an electronic tool that allows the user to set the desired level of humidity for the area where it is placed. As expected, all of the models on our list boast this feature, being mandatory for a top performing unit to have it. This tool makes using the product easy and accurate, ensuring that the user’s preferences are respected.
Another feature that we took into consideration when rating the top tier models on the market is the automatic shut-off capability. This feature basically shows its capability to automatically shut off when the reservoir is full to ensure complete safety. For those who don’t want to opt for continuous drainage, it’s more than mandatory for the model they go with to come with this feature. Of course, all of our choices come with it, so you can rest assured that safety won’t be an issue when using them.
Unfortunately, power outages occasionally happen, rendering all of the electric devices and appliances useless until the power comes back on. When power outages do occur, it’s important for the product that you are using to restart automatically when the power is restored in order to continue and dehumidify even if you’re not there to turn it on again. This feature is one of the rating criteria that we used, the impressive Whynter RPD-711DWP, our choice as the second best model on the market, having it.
Another important feature that we used to rate and rank the top of the line models on the market is the automatic defrosting capability. The compressors are automatically turned off when needed in order to prevent the coils from freezing, thus protecting the appliances and ensuring that they will run smoothly for a long time.
