Dehumidifier

Investing in the best crawl space dehumidifiers is one of the keys to preserving your home or property’s structural integrity. Keep in mind that the crawl spaces aren’t designed to be wet since they are still considered to be a habitable portion of your space, which is directly above the base flood elevation. 

Even if your area is not prone to flooding, humidity can still be a source of the problem in your crawl space. If you can control the rampant moisture, negative effects can ensue, such as wood rot and insulation damage. These things can be a factor of expensive and unwarranted repairs. 

The following dehumidifiers can help you prevent the birthing of these problems. I suggest that you check them out right away.

Why Water And Moisture Exist In Crawl Spaces?

Apparently, there are multiple reasons why water breaches the crawl space. Here are some of them.

• Bulk water – Bulk water refers to the standing water present in your crawl space. If you see an inch or more of water, it is time that you find drainage and leak issues. There’s a good chance that the bulk water is due to the ground’s incorrect sloping outside of your house. 

• Moisture evaporation – If you are living in areas where the ground is moist or full of water, it is a given that your crawl space will probably get wet. At some point, you think that the soil outside is dry. However, that’s the case because the water is already in your crawl space.

It is important that you install a hygrometer in the crawl space to determine if you have moisture evaporation problems that you need to deal with. 

• Vents in the crawl space – Gone are the days where vents are the ideal solution for removing crawl space humidity. If it is damp outside, then the air that gets inside the crawl space will be damp, too. Furthermore, hot conditions can cause a spike in the indoor humidity of your home. It could go as high as 75% relative humidity. 

The Importance Of Having The Proper Humidity Levels In Your Crawl Space

The right humidity in your crawl space is essential for your health. After all, it prevents the growth of mildew and molds, which can cause allergies and other illnesses. Furthermore, controlled humidity discourages the insulation in the crawl space from getting damaged. 

Of course, you also don’t want the structure of the area to get compromised by humidity and water. Wooden components can easily rot and warp if they have prolonged exposure to these elements. 

It is essential that you can identify the cause of the humidity. In this way, you can install the proper measures that could counter it. 

However, high levels of humidity require the service of dehumidifiers. It is your long-term solution to the adverse effects of humidity in your house and properties. 

How To Choose The Best Crawl Space Dehumidifiers

Here are the essential factors that you need to consider when choosing a dehumidifier for your crawl space.

Floor size And Dampness

You have to ascertain first the floor size of your crawl space. You see, dehumidifiers are the most effective if you place them in an area that is within their coverage. For instance, you can’t expect that a dehumidifier can remove moisture in a 3000-square-feet space if it is only designed for 2000-square-feet floor sizes.

Furthermore, you also need to measure the humidity of the crawl space. Specifically, it would really be best if you know the exact moisture levels in the area. In this way, you will be able to configure the dehumidifier properly. 

You can refer to the table below for added guidance:

Condition	Floor Size	Moisture Removal Capacity Of The Dehumidifier
Moderately Damp (60% to 90% Room Humidity)	20000 square feet	166 pints per day
	10000 square feet	86 pints per day
	5000 square feet	46 pints per day
	2500 square feet	26 pints per day
Extremely Damp (80% to 100% Room Humidity)	20000 square feet	289 pints per day
	10000 square feet	149 pints per day
	5000 square feet	79 pints per day
	2500 square feet	44 pints per day

Why Humidity Is A Problem In RVs?

RVs should be comfortable spaces. Unlike other vehicles, you can actually live in an RV. Hence, many outdoor enthusiasts and survivalists often use their RVs as long-term residences. Some even converted them as homes. 

Either way, you have to guarantee that your RV is livable. It should be as comfortable as your house. And to do that, you have to ensure that its internal humidity is properly regulated. You see, when humidity exceeds 60%, the ambient air feels damp and muggy. And despite being damp, the temperature feels hot.

Well, the reason for this is that high humidity prevents sweat from evaporating. It causes you to sweat, but the latter doesn’t evaporate, which makes things extremely uncomfortable. 

Humidity can also make your RV smelly. The odor becomes musty, especially if molds start to grow inside your vehicle. Overall, prolonged humidity can cause damages to the furniture and paint of your RV. If you don’t want to deal with expensive repairs, you have to control the relative humidity of your space. 

How To Choose The Best RV Dehumidifiers

Dehumidifiers are an effective option in combating high levels of humidity. It is a worthy and must-have investment in RVs, campers, and trailers. They are the ones that ensure that the internal moisture remains cool and dry. 

Size of the RV

However, not all dehumidifiers are suited for RV use. For instance, we have to indicate the size of these dehumidifiers to the size of your RV. 

Class A RV has a length of 33 feet. Meanwhile, Class B units are 20 feet long, and Class C motorhomes are around 28 feet. Their average width is approximately 8.5 feet, with an average height of up to 14 feet. Taking these things into account, we can say that whole-house and commercial dehumidifiers might be overkill for motorhomes and RVs. 

Of course, you are still free to get these large dehumidifiers in your RV if you wish so. But if you mind the power consumption that these devices have, you can guarantee that they aren’t the most energy-efficient option out there. 

In fact, the following table emphasizes that it is not always ideal for getting large dehumidifiers for your RV. Even the portable ones can already deal with the moisture problems that are lingering in the vehicle. 

Noise

I also have to indicate that noise is an unwelcome guest in any RV. Unless you made your RV a party platform, it should always remain as silent and cozy as possible. In this way, the residents will experience a noiseless environment. 

You also have to remember that these RVs have closed spaces. Hence, it is easier for the noise to get amplified. If you get a noisy dehumidifier, you’ll eventually have to deal with cacophonous disturbances every day. 

That’s not something you want, right? 

Water Tank Capacity

Since our preference is a portable and compact dehumidifier, it is understandable that their tanks don’t have a vast capacity. But at the same time, we don’t want it to get full after an hour or two. That’s not practical. It would eventually mean that you have to drain it frequently. It could disturb your sleep or any period of rest. 

You should always opt for dehumidifiers to have a decent tank capacity. It’s a needed aspect that completes the ideal ergonomics that every dehumidifier should have. 

Conclusion

The best RV dehumidifiers are crucial appliances for motorhomes, campers, and trailers. You have to expect that humidity may become an issue eventually in the vehicle. These devices ensure that you wouldn’t have to deal with the problem extensively. 

In the long run, it would preserve the structural integrity and convenience of your RV.

How To Choose The Best Whole House Dehumidifiers

Some of us have extensive dehumidification needs. And it’s something that has to be addressed promptly. 

Surely enough, high humidity levels are unhealthy to our bodies and the structural integrity of homes and properties. Once you feel that the dampness in your room is shooting at an anomalous rate, it is time that you get a highly effective dehumidifier. 

Whole House Dehumidifier Vs. Portable Dehumidifiers

If your house is riddled with high levels of moisture, you have two options to take: get a single whole-house dehumidifier or purchase multiple compact dehumidifiers. 

Now, the question here is this: which of them provides the most optimal result?

For me, it has to be these whole-house units. Of course, I am not saying that these portable dehumidifiers are bad and inefficient. However, their function shines best when the humidity problem is enclosed in a single small space. But if the problem persists in various parts of your home, then buying several small dehumidifiers is not the most cost- and energy-efficient move.

Whole-house dehumidifiers are designed to encompass large spaces, regardless of how many rooms are present. If they are placed in a central part of your home, they can effectively lower the humidity of your space. 

Whole-house dehumidifiers also reduce the cost of dehumidification for spacious floor sizes. If you pick those units that have Energy Star certification, you’ll be able to dehumidify your property without compromising your power bill.

Now, let’s discuss the factors that you need to check before buying a whole-house dehumidifier. 

Floor Size

In choosing a dehumidifier, it is important that you can ascertain the overall size of your home. Don’t get a dehumidifier that cannot cover the overall dimension of your properties. Otherwise, you’ll just be wasting your money. 

For extensive dehumidification needs and restoration projects, you might need to get a commercial dehumidifier already. These machines have the right specifications to absorb water at a very responsive rate. They can also run continuously and perform in the most rigorous conditions out there. 

You can refer to the table below so that you’ll have a clear picture of how moisture levels and floor sizes should influence your choice of dehumidifier:

Size Of Your Space
	300 Square Feet	500 Square Feet	800 Square Feet	1200 Square Feet
Conditions	Dehumidifier Capacity
Slightly Damp(50% to 60%)	20 pints	25 – 30 pints	35-40 pints	50 pints
Moderately Damp(60% to 70%)	20 pints	25 – 30 pints	35-40 pints	50 pints
Very Damp(70% to 80%)	25 pints	30 pints	45 pints	55 pints
Extremely Damp(80% to 100%)	25 – 30 pints	35 – 40 pints	45 – 50 pints	60 pints

Drainage Option

Some dehumidifiers let you choose your preferred drainage option. You can either opt for automatic and manual draining. 

Automatic draining is pretty the most convenient choice. You simply attach a hose to its drain plug so that the dehumidifier ejects the water it collected continuously. It is useful for homes that have minimal time to attend to their appliances. 

You can also try manual draining if you want to clean the water tank from time to time. But since we are talking about whole-house dehumidifiers, you have to make sure that the water reservoir is big. You don’t want a shallow tank since it will necessitate you to empty it frequently. And that’s bothersome. 

Energy Efficiency

When choosing a dehumidifier, it is important that it is energy-efficient. Whole-house dehumidifiers, for instance, may consume a lot of electricity if you don’t check their operational mechanisms.

Now, it is quite difficult for non-technical people (like me) to understand the inner workings of an energy-efficient appliance. But one of the best ways to ascertain that such a pedigree exists in a dehumidifier is the Energy Star certification. 

Energy Star is an industrial standard that proves that particular systems, products, and services are not power-hungry. Devices that have these labels can guarantee that you can save power while using them. Therefore, a whole-house dehumidifier must have this proof. 

Conclusion

The best whole house humidifiers are useful utilities for various households and properties nowadays. When you are combating high levels of humidity, this particular machine is your only arsenal. Hence, don’t hesitate to invest in this particular item if you think that your area is quite damp already.

I hope you find this guide useful. If you have other inquiries, feel free to drop them in the comment section below.

How long do dehumidifiers last? 

If you intend to buy a dehumidifier, you should at least know the answer to this question. After all, you should never expect that these dehumidifiers will last for a lifetime. Even the most durable ones are not designed to last for a decade. 

Fortunately, you can always maximize its lifespan. In this way, you wouldn’t have to switch dehumidifiers every year. 

But really, how long is the lifespan of a dehumidifier? 

How Long Do Dehumidifiers Last?

A dehumidifier is a device designed to tackle humidity problems. Specifically, it works by absorbing air and extracting the excess moisture from it. It ensures that the relative humidity in a particular area is at 45% to 55%. 

There are different types of dehumidifiers out there. A refrigerant condenser, for instance, can absorb moisture and convert it to water droplets via a condenser. The water goes to a water tank, which you are going to drain manually or automatically. 

As a result, the air that goes out from the dehumidifier already contains the right level of moisture. 

The dehumidifier repeats this procedure until such time the humidity of particular floor space is already correct. Once this happens, the dehumidifier either shuts down by itself, or you need to switch it off manually. 

Because of the role that the dehumidifier fulfills, its lifespan only sits at 3 to 5 years only. In its later stages, you will notice that its performance has already been reduced. Frequent errors will arise, too. Even those that have durable build may not go beyond the said range. 

However, keep in mind that there are numerous factors that could influence the longevity of a dehumidifier. Let’s discuss them further below. 

Factors That Affects The Lifespan Of A Dehumidifier

Build And Construction

Of course, one could expect that those dehumidifiers that have been made by reputable manufacturers have a longer lifespan than their entry-level counterparts. But that should not surprise you, though. 

When you think of it, these high-quality dehumidifiers are expensive for a reason. Most of them have been engineered with extra-rugged components. They are using technologies, too, that prevent electrical and mechanical damages. 

Of course, other dehumidifiers, such as desiccants, have different mechanisms in absorbing moisture. Hence, their build is quite different from refrigerants. However, this doesn’t mean that they will last for a decade. Over time, the absorbents of desiccants gradually lose their capacity to collect humidity. 

Whether you have a refrigerant or desiccant dehumidifier, their default build does matter. It is something that you have to mind. When you opt for a cheap dehumidifier, you have to expect its flimsy construction. You can’t expect that they can last longer than those expensive dehumidifiers in the market. 

Frequency Of Usage

If you use an appliance constantly and non-stop, its quality degrades fast. It is a fact that applies to every device out there, especially to dehumidifiers. 

Now, your demand for the dehumidifier is different from others. It is different from your neighbor or me. That’s something that you have to take into account. If you have severe humidity problems, then you need to operate the dehumidifier constantly. At this point, you need a dehumidifier that can handle the exhaustiveness of your requirements. 

If you are living in an extremely humid environment, don’t get a weak dehumidifier. Instead, you should get robust units, such as whole-house or commercial dehumidifiers. They can manage non-stop runtime without compromising their overall durability. 

Meanwhile, those that have moderate or minimal humidity issues may not need to run their dehumidifiers all the time. By doing so, they are further preserving the lifespan of the machine, enabling it to operate whenever dehumidification is only needed.

How Long Does A Dehumidifier Have To Run?

It depends. There’s no fixed answer to this question. 

As I’ve emphasized, every one of us has different needs for moisture removal. Some of us only need these dehumidifiers on particular parts of the day. Others have no other choice but to operate their dehumidifiers regularly. 

Hence, you are the only one that can decide when it comes to this particular matter. 

I do recommend that you get a dehumidifier with a humidistat. The latter is a component that reads the external humidity; it works like a hygrometer. Dehumidifiers that have this component will be able to configure their operation automatically. 

For instance, if the humidity is high, these dehumidifiers will work to remove the excess moisture. Once the desired humidity level is achieved, then they will shut down right away. 

The benefit of this mechanism is that it saves your power bill. At the same time, it ensures that the dehumidifier is not overclocking itself. 

Proper Dehumidifier Maintenance

• Be moderate in use – It’s essential that your dehumidifier is only working to achieve safe moisture levels. If you are going to put the desired humidity level at a very low percentage, it will cause the machine to exhaust itself, leaving it susceptible to damages and lifespan reduction.

• Replace its filters – A dehumidifier has filters. You need to replace them regularly to ensure that the machine can work properly. Filters decrease the clogs that could deteriorate the performance of these dehumidifiers. Furthermore, they assist in ensuring that the ejected air is clean. 

• Don’t short-cycle the compressor – The term short-cycling refers to the sudden turning on and off the dehumidifier in just a small period. It is crucial that you wait at least ten minutes before you shut the device. In this way, the pressure inside the dehumidifier gets regulated, preventing unnecessary damages to the compressor. 

• Thaw the coils first – If you notice that the coils have ice on them, you have to defrost them first. Fortunately, some dehumidifiers can do this automatically. But if your dehumidifier doesn’t have this mechanism, you need to wait for the ice to melt first. 

Conclusion

Dehumidifiers don’t have an unlimited lifespan. Hence, it is crucial that you can take care of them to ensure that they can last for as long as they can. Learning the proper usage and maintenance can really make the difference here. 

I hope that you learned a lot from this guide. If you have other related inquiries, feel free to ask me in the comment section below.

How many dehumidifiers do I need in my house?

Surely enough, dehumidifiers are among the most useful home appliances these days. These devices function as moisture removers; they collect excess moisture in the air until such time the humidity levels stay at 45% to 55%. 

Of course, we all know the issues that could take place when the relative humidity shoots up in the scale. It can cause health issues and structural damages, and nobody wants these things to happen. 

While the importance of dehumidifiers has been established long, many are still curious as to its appropriate size and number. Well, I am going to discuss these matters as comprehensively as possible. 

How Many Dehumidifiers Do I Need In My House?

In reality, the answer to this question is quite subjective. 

You see, not all dehumidifiers are the same. Some can perform in exhaustive conditions, while others are designed for portable and compact use only. 

Now, there are various dehumidifiers out there that can handle spaces as large as 4,500 square feet even if they are alone. By investing in them, you will no longer need to buy multiple dehumidifiers. 

Hence, we can say that you only need one dehumidifier in your home, especially if you can get a unit that can do such a job with ease. 

But then again, it is your choice if you want to get multiple dehumidifiers. I have nothing against it.

However, before you hoard these dehumidifiers, you have to consider the following factors first. They are the ones that can help you make up your mind when it comes to the number of dehumidifiers that you need. 

Factors In Selecting Dehumidifiers In Your Home

Your Actual Needs

Let us say that you only live in an apartment with a small floor size. You are riddled with humidity problems, and you want to deal with them right away. Buying a dehumidifier is the soundest solution that you can take. 

The next thing that you have to decide would be the size of the dehumidifier. After all, the bigger the dehumidifier, the more moisture it can absorb. Coincidentally, the size of the dehumidifier also relates to the reach that it has. 

Hence, if your area is small, it is quite an overkill to get a whole-house dehumidifier. I mean, you do have this option, but it is too much. Keep in mind that these burly appliances have a significantly high power consumption than their portable counterparts. Investing in them would mean that you are ready to pay higher on your electricity bills.

This is the part where sizing becomes important. These dehumidifiers are tailored to accommodate a particular space. You can actually see it on their labels and manuals. If you are aware of your actual floor space, it is easier for you to get the right dehumidifier for you. 

Of course, this also helps you determine the number of dehumidifiers. If you are trying to dehumidify a small space, one portable dehumidifier might be enough. But for multiple rooms, you might need to get several units of compact dehumidifiers. 

But then again, let me emphasize that there are large units that can handle multi-room applications on their own. Even if you buy one of these whole-house or commercial dehumidifiers, they can accommodate your needs already. They are pretty useful if you have a large residence or living complex. 

Let’s Talk About Floor Size, Moisture Absorption, And Relative Humidity

It is not good to buy a dehumidifier without knowing the relationship between floor size, relative humidity, and moisture-capability of a dehumidifier. These three factors are quite connected; they can help you decide to type and number of dehumidifiers that you need. 

The bigger your area, the more powerful the dehumidifier that you need to buy. However, you also have to ascertain the relative humidity first. It will let you determine if you need a workhorse or not. A hygrometer will aid you in this particular matter. This device reads the relative humidity of a particular room. 

Some dehumidifiers are equipped with a humidistat. It works like hygrometers; it will read the relative humidity of your space and adjust the performance of the dehumidifier based on it. 

Again, if your area is big and has severe humidity problems, you might need multiple dehumidifiers running in place. Alternatively, you can get a single powerhouse that is capable of robust dehumidification. 

The table below will help you understand the connection between these three factors. Keep in mind that this table can also serve as your guide whenever choosing the best dehumidifier.

Size Of Your Space
	300 square feet	500 square feet	800 square feet	1200 square feet
Conditions	Dehumidifier Capacity
Slightly Damp (50% to 60%)	20 pints	25 – 30 pints	35 – 40 pints	50 pints
Moderately Damp (60% to 70%)	20 pints	25 – 30 pints	35 – 40 pints	50 pints
Very Damp (70% to 80%)	25 pints	30 pints	45 pints	55 pints
Extremely Damp (80% to 100%)	25 – 30 pints	35 – 40 pints	45 – 50 pints	60 pints

Energy Concerns

Of course, more appliances mean higher electricity bills. It is not a surprising thing, though. It is a trade that you need to accept once you decide to get multiple dehumidifiers in your home. 

If you are going to opt for this route, you have to make sure that each of your dehumidifiers has an Energy Star certification. This one indicates that the device has been constructed in a way that it will not consume excessive loads of electricity. 

Energy Star dehumidifiers can operate at a stable rate, too. They have ample protection built within them to ensure that they are not susceptible to overloading and other forms of mechanical damages. 

When it comes to large dehumidifiers, power consumption should not pose much of a concern, especially if they have the Energy Star certification. Even if you say that they provide extensive moisture-removal capabilities, this doesn’t indicate that they will double your power bill. Again, energy-efficiency should be a factor here.

Conclusion

It is important that you choose your dehumidifiers wisely. It is a pivotal aspect that ensures that you can have a reliable dehumidification tool for your home. 

You have the freedom to get multiple dehumidifiers for your home, especially if you think that one unit is not enough to dehumidify your house. As long as you can eliminate the moisture problems, this option should not be a problem. 

However, large dehumidifiers may come more applicable and practical for whole-house and extensive restoration projects. They alone can deal with much of the effects of high humidity.
