Best Bathroom Dehumidifier

In this article we go over some of the reasons people use dehumidifiers in their bathrooms. Later on  we review several dehumidifiers and highlight some specific features that make them unique.

Trying to find a dehumidifier for your bathroom is a unique challenge. Space is generally a concern. Because of this you need a small dehumidifier but small dehumidifiers don’t have very large capacities. This means that you will need to empty it often. To solve this problem we searched available dehumidifiers to find the smallest one with an automatic pump to drain its water reservoir. Because of this unique feature it is the first dehumidifier we review in this article.

DeLonghi 45-pint Dehumidifier with Patented Pump

This is the single dehumidifier we review in this article that has a pump to automatically drain the water tank. You can also manually empty the tank if you do not wish to use the hose. As we stated earlier this is the smallest dehumidifier with a pump available today. It measures 15.3 in wide by 12.4 in deep and it is 24.3 in tall. Depending on how your bathroom is set up you may easily be able to fit this next to your toilet and have the hose drain into the shower. this would allow the dehumidifier to run continuously without having to worry about the tank filling up.

Best Small Bathroom Dehumidifier

Some people may try mounting their dehumidifiers on the wall or off of the ceiling. This can save valuable floor space that may not be available in the first place. While there are no dehumidifiers on the market today that will easily mount on the wall, there are several that we review here that would be suitable for placement on a small shelf on the wall.

PureGuardian Dehumidifier

The PureGuardian Dehumidifier is one of the smallest dehumidifiers on the market today. Its base measures 5.2 in by 8.1 in and it is 13.4 in tall per the manufacturer’s specifications. this means that it can easily fit on the back of a standard toilet tank or right on the sink and not take up very much space. Also because of its small size you might consider placing it on a shelf mounted to the wall. The one downside is that the tank is only 360 ml. This is about one and a half cups.

The PureGuardian Dehumidifier uses a Peltier cooler to remove condensation from the air. This is different from a dehumidifier that uses a compressor. The vast majority of dehumidifiers on the market use compressors to remove unwanted humidity from the air. The advantage to the Peltier cooler  is that it is very small. That is what gives this dehumidifier its small footprint. Peltier coolers are not commonly used however because they are not very efficient when compared to the compressors in regular dehumidifiers.

Other Small Dehumidifiers with Peltier Technology

Here is a short list of several other small dehumidifiers for your bathroom that use the same kind of Peltier cooler the PureGuardian uses.  we will only provide short descriptions here because they are more or less the same. They differ slightly in their dimensions and capacities. At the end of this list we have a convenient search bar to help you research any of these dehumidifiers.

hOme Small Dehumidifier

hOmeLabs makes a small dehumidifier rated for a 150 square foot room. The tank has a capacity of 16 ounces and the dehumidifier can remove up to 9 ouces of water from the air per day. It comes with an automatic shutoff feature and a six foot power cord. The outside dimensions are 6.5 inches by 5.3 inches by 8.5 inches.

Eva-Dry 1100 Petite Dehumidifier

Eva-Dry has several small dehummidifiers in their product lineup. They have some dessicant dehumidifiers that do not need batteries or a power cord. They work by absorbing water into a gell material that is later dried out using heat. If you are looking for a small dehumidifier for your bathroom, check out the 1100 or the Eva-Dry 2200 Electric Dehumidifier. The 1100 has an 8 ounce tank while the 2200 has a 20 ounce capacity. The 2200 is wider and taller so if space is your major concern you will want to consider the 1100 first. Conveniently, the numbers in Eva-Dry dehumidifiers stand for the cubic feet they are capable of treating.

Powilling 1500ML

This Powilling dehumidifier has a very large capacity for a Peltier type dehumidifier of just over 50 ounces. It is capable or removing 14 ounces of water from the air per day. It is definitely one of the more powerful small dehumidifiers you could use in your bathroom. it is bigger, measuring 13.7 inches by 9.4 by 7.4.

Best Crawl Space Dehumidifier with Pump

In this article we talk about the unique challenges you face when trying to use a dehumidifier in your crawl space. People generally use dehumidifiers in their crawl space for the same reasons they use them in their basement, removing mold or excess moisture. However, there are additional situations to consider when trying to dehumidify your crawl space.

When you use a dehumidifier in your basement it’s fairly simple. There is at least one drain in every homes basement period this drain can easily take care of the water coming out of the dehumidifier if you decide to use a hose. The other option would be just to walk down to your basement and empty the water collection pan whenever it needs it.

Crawl spaces on the other hand are not so easy to get to. It would be very inconvenient to get into your crawl space everyday or every other day to empty the water collection pan. Also crawl spaces don’t have drain so you cannot use the dehumidifier hose. There is a solution and it is to use a dehumidifier with a built in pump.

Dehumidifiers with built-in pumps

Dehumidifiers with pumps can push the water up word. This means that if you have an opening near the top of your crawl space you can put the hose out the opening and still expect the water to be pumped out. This is a unique feature that you must have in any dehumidifier you plan to use in your crawl space.

Essential features

Additionally, you would also want your dehumidifier to be able to treat a large area. Most crawl spaces go underneath the entire house. Luckily most manufacturers that make dehumidifiers with built-in pumps put them on their higher-capacity dehumidifiers. We directed our research into dehumidifiers using these two features, a built in pump and high capacity, to narrow the field.

Other Considerations

We also considered how well-known the manufacturer’s brand is and their reputation for quality. This let us to pick the Frigidaire 70 pint dehumidifier with pump as the best dehumidifier for your crawl space. In the next part of this article we review the other features that really made the Frigidaire dehumidifier stand out from its competitors.

We have included a search bar in the ad below to help you find relevant products based on the content of this page.


Washable Filter

One of the first things that caught our eye was the fact that the air filter is washable. This is not a HEPA filter like you might expect from an air purifier. it’s only function is to keep large particles of dust and debris out of the dehumidifier. Because of this you can easily wash it and use it over. It is possible to damage the filter, so Frigidaire does make replacements. One downside is that you cannot use the filter until it is dry. The manufacturer also advises against using something like an electric hair dryer to speed up this drying process. Because of this some people will order a second filter when they purchase their dehumidifier. This means you can continuously run your dehumidifier without waiting for the filter to dry.

Dehumidifier Pump

The maximum rise and distance that the dehumidifier pump will work is 5 meters according to Frigidaire. This translates to just over 16 feet. if you use a hose longer than this it is possible to damage the pump. One thing to remember is that the water inside the hose has wait. As long as the hose is on an upward angle this water is pushing back against pump. The pump is only so strong and cannot move the water further without risking damage.

The dehumidifier hose should have a diameter of 11/16 of an inch. This is not the same size as a traditional garden hose. Dehumidifier hoses are widely available and do come in lengths of up to 16 feet.

Best Crawl Space Dehumidifier with Pump

Based on our research of the top dehumidifiers on the market we concluded that the Frigidaire 70 pint dehumidifier with built-in pump is the best dehumidifier to use in a crawl space.

Dehumidifier vs Air Purifier for Mold

In this article we compare dehumidifiers and air purifiers and their effectiveness for dealing with mold. Both of these air treatment appliances have the capability to help solve a mold problem.

Mold produces spores that become airborne in order to spread.  These mold spores are everywhere, indoors and Outdoors. Some people have allergies to mold spores and may want to pay close attention to the mold spore count in their area.

In addition to problems with itching allergies and sneezing mold can also damage property. Mold can repair require expensive repair and remediation services. One of the most common places for mold form in home is on the windowsill. This is because excess moisture in the air will condense on cold Windows during winter months. Mold can also develop in the attic or basement where there is generally inadequate ventilation.

Since mold spores are airborne, they can be captured by an air filter.  Usually they remain here until the filter is either cleaned or replaced. However, if there is enough moisture in the air the mold can begin to reproduce on the air filter. In this situation the air purifier or ventilation system is actually spreading mold spores every time it turns on. Air purifiers are a great way to lower the number of mold spores in the air. They do need to be maintained regularly to ensure their effectiveness.

Humidity and Mold Growth

Mold needs humid air in order to spread and grow. If you can use a dehumidifier to keep humidity levels below 50% you will be taking a significant step toward preventing the spread and growth. Since regular things like cooking and using the shower increase the humidity inside a home, we recommend using a dehumidifier. A dehumidifier will control the humidity levels and consistently keep them below 50%.

The Centers for Disease Control and prevention recommend this level of 50% relative humidity in order to prevent mold growth. They also indicate that an air conditioner can help control humidity levels the same way a dehumidifier will. While this is true, dehumidifiers tend to be much more energy efficient than air conditioners. You can also use dehumidifiers in the winter when an air conditioner would not be practical.

If you need to clean mold off surfaces, the Centers for Disease Prevention and Control recommend a cleaning solution of no more than 1 cup of bleach mixed with 1 gallon of water. They have additional tips and warnings here.

Maintenance

Dehumidifiers, like air purifiers, also need regular maintenance. Their water catch bins must be emptied regularly if the dehumidifier is not routed directly to a drain. People often use dehumidifier hoses to accomplish this. The water collection bins must be cleaned to prevent mold growth inside. And dehumidifier hoses must be cleaned regularly to reduce the buildup of mineral deposits.

Both air purifiers and dehumidifiers will help reduce the spread of mold in your home. Both of these appliances require regular maintenance in order to function correctly. They will both help manage allergies to mold as well. We suggest using dehumidifiers and places where moisture is likely to collect. This could be in your basement or bathroom. Additionally you can use an air purifier where you spend the most time. This would most likely be your bedroom since you sleep there at night.

Dehumidifier vs Tumble Dryer

In this article we are going to compare a dehumidifier to a tumble dryer. If you are interested in the differences and similarities between these two appliances it is safe to say you want to use them to dry your clothes. Because of that, the main focus of this article will be the differences in energy consumption. It will be up to you to decide which is more practical and which is best for your situation. We are going to do the heavy lifting of figuring out which one is more energy efficient. Later on in the article we will bring up a few practical considerations when it comes to operating each of these appliances.

Energy Efficiency

One thing that is always important to look for when purchasing an appliance is energy star certification. This is an important thing to look for because of a number of reasons. First it shows that the manufacturer was confident enough in their product that they were willing to let a third party inspect and certified that product. Also since the energy star certification relates to how efficient the appliances you can be sure that relative to other products in the same class, this one should save you money on your energy bill.

An important thing to note is that this certification is important when comparing products of the same type.  an energy STAR certified dehumidifier is not the same as an energy STAR certified tumble dryer. Tumble dryers use anywhere from 1800 watts to 5000 watts in an hour.  A typical tumble dryer will use about 3000 watts in an hour. Dehumidifiers on the other hand generally use less than 300 watts an hour. A tumble dryer using 3000 watts an hour and a dehumidifier using 300 watts an hour can both be energy STAR certified. This certification means that an energy STAR certified dryer has been verified to meet certain efficiency standards. A tumble dryer that is not energy STAR certified could be more efficient than one that is certified. However, there is no verification by a third party to guarantee this.

Costs of Operation

Earlier in this article we said that a typical tumble dryer will use about 3000 watts of electricity in an hour. This is quite a bit of electricity compared to a dehumidifier that only uses about 300 watts in the same time frame.  This isn’t exactly a fair comparison though. A tumble dryer will have your clothes dried  in about an hour.  If you are using a dehumidifier to dry your clothes you can expect it to take more than an hour. So if we do the math here, we see that this dehumidifier could run for 10 hours straight before using the same amount of electricity as the tumble dryer. Take the 3,000 watts used by the dryer divided by the 300 watts the dehumidifier uses.  the result is 10 hours of run time for the dehumidifier compared to 1 hour of run time for the tumble dryer.

It is pretty safe to say that it will take her clothes less than 10 hours to dry even if you hung them on drying racks. The dehumidifier used near drying racks will shorten the time it takes to dry your clothes. Based on the calculations above we can confidently say that a dehumidifier is much more energy efficient when compared to using a tumble dryer for your clothes. Next up we show one of the less obvious ways a tumble dryer can increase your energy bill.

How does a tumble dryer work?

A tumble dryer works by pushing heated air past wet clothes. the heated air carries the moisture away and is vented outside your home. This is a very simple explanation but it will suit our needs for this discussion.

There is an intake port usually located on the back of all tumble dryers. This is where the dryer sucks air from your home into the appliance. Next the air is heated blown past the clothes and vented outside. The dryer is taking air from your home that is already heated or cooled to a comfortable temperature and pushing it outside. as this air leaves you home it is slowly replaced by air leaking in through the seals on your windows and doors. Anytime your tumble dryer is running it is continuously taking comfortable air out of your home and pushing it outside while overtime pulling outside air into your home.

Most tumble dryers require an exhaust vent capable of handling over 200 cubic feet of air per minute.  The manufacturer expects the dryer to pull at least 200 cubic feet of air per minute from your home and put it outside. If you multiply this by 60 minutes, we spoke about an hour of run time earlier, you come up with 18,000 cubic feet of air. This is an incredible amount of energy when compared to a dehumidifier.

Dehumidifiers do not have an external exhaust port that moves air from inside your home to the outdoors.  If you ever open a dryer in the winter time you will notice that it is very cold. Even when the dryer is not operating it is still leaking heat out of your home.

Other operation considerations

Sometimes when your dryer has finished its cycle of operations some of your clothes are still damp. Here you are faced with a choice of either hanging up your clothes on a drying rack or running the dryer again. Running the dryer for a second cycle uses huge amounts of energy compared to leaving the clothes on a dryer rack.  If you are drying your clothes with drying racks and dehumidifiers, you don’t need to worry about this kind of decision. The dehumidifier will run until the humidity levels in the surrounding air are where you want them.

It is important to either check that water collection bin of your dehumidifier often or 2 have the dehumidifier pour directly into a drain. If you forget to check the water collection bin the dehumidifier will automatically turn off. This could lengthen the amount of time until your clothes are dry.

Final thoughts on dehumidifier vs tumble dryer

All this being said a tumble dryer is very convenient it just isn’t efficient. When using the dryer you do not have to worry about hanging all your clothes on dryer racks. However some clothes are not safe for tumble dryers. They need to be hung up on a drying rack anyway. One option that might make the most sense is to use a dehumidifier with drying racks for smaller loads of laundry. You could save the tumble dryer for larger loads or those that have towels and other items that are difficult to dry. Hopefully we have presented enough information for your to make an informed choice when comparing a dehumidifier to a tumble dryer.

Best Dehumidifer for Gun Safe

It is very important to keep humidity out of your gun safe. If you live in a very humid environment this is a real challenge. Hunting season in colder climates can also exposure guns to humidity. When you come back in from the winter weather the ice cold metal components become saturated with condensation.

This is the same idea of a cold beverage on a summer day. The humidity naturally in the air comes into contact with something cold and condenses. It is pretty easy to wipe this water off the outside of your hunting rifle. But what about the trigger housing and lower receiver? There are a lot of small spaces that are difficult to reach with a cloth or Q-tip.

An easy way to solve this is keeping a desiccant dehumidifier in your gun safe. While you store your guns for the night the dehumidifier will do it’s work. The extra dry air inside the safe turbocharge the evaporation process. The extra water will be removed before it can do any damage or rust metal components.

We recommend the Eva-Dry Renewable E-333 Wireless Mini Dehumidifier to do the job of dehumidifying your gun safe for several reasons. First and foremost is affordability and the fact that you can recharge it without purchasing additional parts. It’s small size and cordless operation also make it a clear winner. Feel free to keep reading for a more in depth review below, or click through to Amazon to see this and other cordless desiccant dehumidifiers.


The presence of extra humidity in places such as safes, closets, bathrooms, under kitchen sinks, inside boats, in RVs and so on, can cause nightmares. This excessive humidity can be taken care of if you use the E-333 dehumidifier.

By using the “Eva-Dry Renewable E-333 Wireless Mini Dehumidifier”, you can save energy as it does not operate on either electric power or on a battery. Though it is not suitable for large areas, it is ideal for small places like bathrooms and closets where there are chances of growth of mildew and molds.

Mode of operation:

The E-333 dehumidifier does not need electric power or batteries but works on a technology that requires replaceable silica gel. The dehumidifier can quietly absorb all the moisture in an area efficiently for an area up to 333 cubic ft. The Silica gel color can be seen in a small window, to assess how much moisture that has been absorbed by crystals.

Note: The unit does not have any indicator that lights up, and only the color of the beads have to be checked regularly. Within two to four weeks, depending on the amount of moisture present, the color of the silica gel beads will change to green when they have absorbed moisture to their full capacity of 4 to 6 ounces. After this happens, the dehumidifier has to be kept in a well-ventilated location for 8 hours to 10 hours to allow the crystals to lose the moisture and revert to their orange color. They can now be used repeatedly and for up to 10 years.

Previously the color of the crystals used was blue which used to change to pink when they became wet. The model E-333 humidifier is effective for small spaces. Remember that the place beside an open window in a large room or an area outside the house is the best place for allowing the humidifier to release the moisture into the air.

No need to buy fresh beads or cleaning up after a spill!

There is no chance of water spilling out, even when the E-333 has absorbed moisture to its full capacity. It can retain all the moisture till the beads are renewed by allowing the absorbed moisture to evaporate. Thus, costly refills can be avoided and the dehumidifier with warranty coverage of 5 years can repeatedly be used for ten years.

Advantages of the E-333 dehumidifier are:

It is non-toxic
It can be renewed and used for ten years
Works silently
No danger to children and pets
No spills and no mess
Can work excellently for an area measuring 333 cft.
Breaking down the characteristics

How it performs

Best Dehumidifier for Basement Mold

It can be hard to treat mold in your basement. Since there is less air circulation and generally cooler temperatures, it makes a good opportunity for pockets of moisture to build up. Things like mold and other fungi can take hold in these moist areas. Keeping your basement dry is an important part of removing and keeping mold out of your basement. This is especially important if you have a finished basement and a bathroom or shower installed.

We go over a list of different features that make desiccant dehumidifiers the best ones to help remove mold from your basement. Further down the article we review some of the features for our top pick – EcoSeb DD122EA-SIMPLE Desiccant Dehumidifier.

Moisture can also leak in through the walls of your basement. If your home is situated at the bottom of a hill this is very common. Rainwater will soak into the hill and gradually flow down with gravity. As the water moves through the soil it will run into the side of your basement. Over time this water seeps through the walls.

Dehumidifiers that rely on compressors do not function very efficiently in colder environments like the basement. Compressor dehumidifiers have peak efficiency around 68 degrees F. If you need your dehumidifier to work well in the cold, look for one that is a desiccant dehumidifier. They will function all the way down to 34 degrees F.

Desiccant dehumidifiers use small wheels or discs with silica gel to remove moisture from the air. They continuously regenerate the silica gel with slightly heated air so that you do not need to replace the silica gel. Another advantage desiccant dehumidifiers have over compressor dehumidifiers is that they can run very quietly. They only use a fan, which does not make as much noise as a compressor will.

Compressor dehumidifiers use a compressor to cool down metal coils. This is the same idea as condensation on the outside of a glass of ice water. This condensed water from the air falls into the tank or gets drained by a hose. The problem with compressor humidifiers is that if the air is already cold, they will struggle to cool their coils enough to cause condensation. This is why we recommend using a desiccant dehumidifier to help remove mold from your basement. Water damage restoration professionals rely on commercial grade desiccant dehumidifiers for this same reason.

Below we review some of the functions and capabilities of the EcoSeb DD122EA-SIMPLE dehumidifier.

Operating Temperature Range

DD122EA-SIMPLE operating temperature range is 34 to 95 degrees F. Compressor based dehumidifiers have a peak efficiency of 68 degrees F. If you need the dehumidifier to work in a place with temperatures lower than that, the desiccant dehumidifier is the best choice. It is sufficient for most of the operations, and thus it makes the design one of the best suited for diverse applications.

Humidistat

Though there is no digital display for showing the readings of the humidistat, similar to what you get on a compressor based unit. But, the design comes with a built-in humidistat. You can buy a separate hygrometer unit, to measure the humidity in the room, else you can also reply on the dehumidifier set to do the work without any need to measure it.

The EcoSeb DD122EA-SIMPLE can be set to a relative humidity range of 40% to 80%. It is done by manually adjusting the knob and works fine.

Number of Fan Speeds

Usually, the compressor based units come with two fans setting, high and low. It helps in controlling the noise due to fan operation, higher the fan speed more will be noise, the choice is to the customer if they are ready to adjust their dehumidification needs in exchange for quite an operation. Though in case of EcoSeb DD122EA-SIMPLE one cannot directly regulate the fan speeds, the operation logic does use the feature of automatically adjusting the fan speed as per the operational needs.

Extra Modes

The unit EcoSeb DD122EA-SIMPLE has relatively simple control consisting of one adjustable dial knob and one selection adjustor switch.

Laundry mode

The unit is equipped with a continuous mode-called laundry mode, in which the unit will not shut off, irrespective of what the humidistat reads as the ambient air’s humidity level. The unit will shut only when the water collection bucket is full, that has the switch to turn off the dehumidifier unit.

The DD122EA-SIMPLE also has the provision of multiple auto modes of low, medium and high settings.

Economy/Turbo Modes

In DD122EA-SIMPLE you can set the unit to the economy or the turbo mode. This can be done by operating the switch on the control panel. The economy mode is for low power consumption, in which the low fan speed is used. In turbo mode, the dehumidification shall be achieved to the desired level faster due to higher fan speed, but you will have to face higher energy bills and more noise levels.

Energy Efficiency

As per the mode selected by the user, the DD122EA-SIMPLE consumes from 300 to 615 watts power. The power consumption in high, dry or the turbo mode can be as high as 615 watts. This comparable to the compressor based units, which consumes 300-400 watts with low capacity designs of 30 to 40 pint. The bigger units can consume power up to as high as 700-800 watts.

Moisture Removal

The DD122EA-SIMPLE units have many modes to achieve different humidity levels as low, medium and high. The same can also be obtained at various speeds by selecting the economy or the turbo modes.

Portability

DD122EA-SIMPLE is easily portable. This is one significant advantage compared to the compressor based units that are heavy as they consist of heavy parts like compressor, condenser and the evaporator. The desiccant design, similar to the DD122EA-SIMPLE, has lighter parts. The unit weighs only 13.2 pounds. The compressor-based unit of similar operation capacity will weigh as much as 30-50 pounds. If you have to move quite often, then DD122EA-SIMPLE is the best choice for you.

Warranty (Manufacturers)

The DD122EA-SIMPLE has two years manufacturer’s warranty. This is better than the compressor based units that come with one year warranty. Extra warranty of any covers typically only the compressor.

Value

The DD122EA-SIMPLE is one of the cheapest in the range. Its price comes somewhere between the cost of 30 to 50-pint compressor based designs. But, looking at the versatility of DD122EA-SIMPLE it is the best value for money.

Reliability

Due to its time-tested and rugged designs, with minimum electronics, the design of DD122EA-SIMPLE works fine for the long duration of operations.
