What You Should Know About these Devices

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.

Types of Dehumidification Devices

Although all dehumidifiers serve the same purpose, which is to extract the excess moisture in the room or area that they’re placed in, these devices come in different types. The three main types that you will encounter and that you need to learn about in order to make the right choice for you are refrigerant units, desiccant units, and whole house models. In the following, we will tell you everything you need to know about each type so that you will be better informed.

  • Refrigerant

  • 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

  • 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

  • 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.

Signs You have Excessive Moisture Issues

In many cases, people are dealing with excessive air humidity and they don’t notice it either because they are are not familiar with the signs or because they don’t know where to look. To make sure you never overlook this aspect, here are the most common signs that your indoor air is excessively humid.

  • You are Having Difficulties Breathing

  • 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.

  • Your Home Feels Too Hot

  • 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.

  • You are Struggling with Mold and Mildew

  • 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.

  • You Spot Condense on the Windows

  • 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.

Cleaning and Maintenance Advice

What you will be surely glad to hear is the fact that dehumidifiers don’t require much maintenance hustle. Therefore, you won’t lose a lot of time taking care of the appliance but rather have to spend a small amount of time once in a while to upkeep it. To find out how to properly clean the device and what maintenance work needs to be performed on it and when you should do it, read the following lines.

  • Cleaning Tips

  • 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.

  • Maintenance Tips

  • 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.

The Advantages of Using a Top of the Line Product

While you might be informed regarding the properties of these household appliances, being already aware of the fact that they help lower humidity levels, this doesn’t mean that you know everything about the advantages that they come with. To have a clearer image of how important it actually is to own a dehumidifying device, read this section of our article to find out what advantages the top of the line models on the market come with.

  • Prevent Mold and Mildew From Appearing

  • 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.

  • Reduce Dust Mite Population

  • 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.

  • Help Reduce Odors

  • 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.

  • Prevent the Corrosion of Electronics and Tools

  • 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.

  • Dry Clothing Faster

  • 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.

  • Lower Energy Costs

  • 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.

How to Figure out What is the Perfect Size

The most important step that you have to take when you decide that you need a dehumidifier is to figure out what size it should have to comply with your needs. Otherwise, you might have to deal with the consequences of buying a model that has a small overall size when compared to what you actually need, being impossible for it to effectively lower humidity levels. Therefore, don’t underestimate the need for a perfect sized unit, or you might be stuck with an underperforming model.

  • Determine the Humidity Levels

  • 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.

  • Calculate the Air Changes per Hour Required to Remove the Excess Moisture

  • 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.

  • Determine the Size of the Area Where it Will Be Placed

  • 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.

  • Determine the Air Flow Needed to Dehumidify the 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.

  • Calculate the Pints of Moisture That Need to Be Extracted on a Daily Basis

  • 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.

How to Choose the Best Model

No investment should be done without proper research, especially when it comes to household appliances of a great importance. If you want to settle for nothing but the best, make sure that you carefully read this section of our article to find out what you must look for to choose a great performing model.

  • Match the Size to the Moisture Levels

  • 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.

  • Pick a Model with a Humidistat

  • 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.

  • Look for the Continuous Drain Option

  • 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.

  • Choose a Model That Features a Timer

  • 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.

  • Take Energy Efficiency Into Consideration

  • 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.

Of course, all of our choices come with it, so you can rest assured that safety won’t be an issue when using them.

  • Automatic Restart

  • 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.

  • Automatic Defrosting

  • 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.

Frequently Asked Questions

?Does the dehumidification appliance release heat in the area it is placed in?
Yes, it does indeed release heat in the immediate environment – usually between 5 and 8 degrees Fahrenheit if the room is extremely small. Of course, how big of an impact the heat fluctuation has on the environment depends on the area’s size. Another factor which affects this outcome is the size and capacity of the dehumidifier itself, bigger models generating more heat as they operate.

?If I want an energy efficient appliance, how do I make sure the purchase I go with is the right one?
If you want to be 100% sure that the dehumidifying appliance you choose is indeed energy efficient, look for the Energy Star rating. This is an international designation which indicates the appliance has been deemed by experts to be energy efficient, thus consuming a lot less energy to run when compared to other products in its niche.

?What does the capacity of the appliance indicate?
The dehumidifying appliance’s capacity indicates the amount of moisture it is capable of removing from the air over a 24-hour period. Obviously, this is the rating you should focus on the most when making the purchase to ensure you will not spend your money on a dehumidifier that over or under performs.
