Keep relative humidity below 60% for a healthy home

Humidifiers are useful for reducing and preventing condensation, mould and bacteria growth. They are particularly useful in damp parts of the home like the bathroom.

You should try to keep relative humidity (RH) below 60% in order to prevent the growth of bacteria and mould. A dehumidifier will help you do this, and can also be useful for drying your washing.

Best Desiccant Dehumidifier

What’s the best desiccant dehumidifier available in the UK? After researching the market and comparing the options available, we believe it’s probably the EcoAir DD122FW-MK5. Read on to find out more about it.

EcoAir DD122FW-MK5

Desiccant dehumidifiers are a more modern approach to dehumidifying. Instead of using a cold plate like a compressor dehumidifier, they use an absorbent material that absorbs moisture from the air in a similar manner to a sponge. They then use a heater to remove the moisture from the desiccant material. This makes a desiccant dehumidifier far more efficient in colder temperatures. If you need to dehumidify a room that’s often below 15°C, then a desiccant dehumidifier is likely the way to go.

Our favourite desiccant dehumidifier is the EcoAir DD122FW-MK5 for its solid performance and excellent list of features. As with many desiccant dehumidifiers, it’s remarkably cheap to run, although its extraction rate leaves a little to be desired if you live in a larger home. But for cold basements or apartments, then it’s certainly a tempting option.

Specifications

Dimensions: 17.5 x 29 x 47.5 cm
Capacity: 2 Litres
Power: 580 Watts

Power and Features

The power from this product is certainly respectable. In low temperatures, this dehumidifier will out-class most compressor dehumidifiers. Because compressor dehumidifiers rely on a cold plate to remove moisture from the air, as the room gets colder, the dehumidifier must work harder. A desiccant dehumidifier like the EcoAir DD122FW-MK5 doesn’t have that problem, making it ideal for cold basements.

The features on this product are impressive. It features a germicidal filter, a humidistat with automatic performance tuning, a configurable timer, an anti-drip mechanism, tilt protection, and an automatic shutdown for when the 2L tank is filled. This product is extremely convenient to use

Summary

In cold temperatures, the performance of a desiccant dehumidifier is unbeatable. The EcoAir DD122FW-MK5 is a fine choice if you’re looking for a good balance between performance, features, and efficiency. EcoAir’s whole range of desiccant dehumidifiers are excellent, but we think that the DD122FW-MK5 is where the value for money is at.

 

Best Rechargeable Dehumidifier

After researching dozens of rechargeable dehumidifiers available in the UK, we’ve picked out the Pro Breeze Cordless Rechargeable Mini Dehumidifier as potentially the best rechargeable dehumidifier on the market in 2017. Read on for its key specs and to find out how it performs.

Pro Breeze Cordless Rechargeable Mini Dehumidifier

Small spaces such as closets, caravans, or boats can be tough to keep dry. Especially since there may not be somewhere where you can plug a dehumidifier in. That’s where the Pro Breeze Cordless Rechargeable Mini Dehumidifier comes in. This mini dehumidifier can be charged and then simply placed in a small area you want to keep dry.

Specifications

Dimensions: 18.6 x 15.4 x 5.2 cm
Weight: 581 g
Runtime: 2-4 weeks per charge

Power and Features

Unlike all of the other dehumidifiers on this list, it does not have a water tank. Instead, it uses absorbent crystals to pull moisture from the air. Then, when the device is recharged, it heats the crystals up and re-releases the moisture back into the atmosphere. This gives it a great runtime per charge. Unfortunately, this does mean that you’ll have to recharge it somewhere with good ventilation otherwise your moisture problem won’t improve.

This product is designed to be very convenient. If you find yourself dealing with excessive moisture in enclosed areas, it’s unlikely that you’ll be able to get power there easily. For keeping moisture out of your cupboards or wardrobes, this product is ideal. Because it’s rechargeable, you can even use it on the go—simply throw it into a gym bag and you won’t have to worry about mould growing inside.

Summary

The Pro Breeze Cordless Rechargeable Mini Dehumidifier is a highly effective moisture control solution for small enclosed spaces. There’s no need to worry about taking up an electrical socket or finding a way to run power to it. Simply recharge it every few weeks, and it’s good to go.

 

Most Energy-Efficient Dehumidifier

After researching and comparing the energy efficiency ratings of dozens of dehumidifiers, we’ve picked out the Meaco 12L Low Energy Dehumidifier as one of the most energy-efficient dehumidifiers currently on the market. Read on for our review and to see its key energy efficiency specs.

Meaco 12L Low Energy Dehumidifier

This is the second product from Meaco we’ve reviewed so far, and for good reason. Meaco’s Low Energy line of dehumidifiers are absolutely superb. There are three products in the range, rated on their manufacturer extraction rates: 12L per day, 20L per day, and 25L per day.

This is the least powerful of the three, but the reduction in power makes it extremely efficient to run in smaller homes or homes with only minor moisture issues.

Specifications

Dimensions: 24.8 x 48.5 x 32.5 cm
Capacity: 2.5 Litres
Airflow: 100m³/hour
Approx. Electricity Cost: 2.53p/hour based on 15.32p/kWh

Power and Features

As with all dehumidifiers, the manufacturer rated extraction rate is higher than the real-world performance. However, that doesn’t mean that the real-world performance is lacking. Of course, it’s not nearly as powerful as many other products on the market, but it makes up for it by being incredibly energy-efficient.

If you live in a small house or an apartment, then this product is likely to be more than sufficient in dealing with your moisture problems. Rated at 2.53p per hour to run, this dehumidifier is incredibly efficient. Since this product is only likely to be running for a few hours a day, the increase on your electricity bill should be negligible.

Summary

For energy-efficiency in a small home, we believe the Meaco Low Energy Dehumidifier is one of the best. The whole Meaco Low Energy line of dehumidifiers are an excellent choice for performance and power consumption, but if energy bills are your primary concern then it’s wise to choose the lower power option unless your moisture problems are more severe.

 

Quietest Dehumidifier

Are you looking for an effective dehumidifier that doesn’t make much noise? We’ve researched the quietest dehumidifiers on the market in the UK and believe the De’Longhi Compressor Free Compact Dehumidifier is one of the best quiet dehumidifiers you can get in 2017. Read on for more information about it.

De’Longhi Compressor Free Compact Dehumidifier

Dehumidifiers can be noisy. This is in part due to the compressor inside of a traditional compressor dehumidifier. De’Longhi have created a dehumidifier that uses a compressor-free design. Compressor-free dehumidifiers are nothing new, in fact most desiccant dehumidifiers lack compressors. However, for a 12L dehumidifier this product is remarkably quiet.

Specifications

Dimensions: 28.9 x 17 x 47 cm
Capacity: 2 Litres
Weight: 6 Kg
Noise Level: 34 dB

Power and Features

Finding the right balance between quiet and powerful can be tough. De’Longhi have created a dehumidifier that ditches the compressor, saving weight and making the whole unit far quieter.

The manufacturer promises whisper-quiet running at 34 dB, though real-world performance is likely to be louder, depending on the flooring it’s on. To put it into perspective, 34 dB is just slightly quieter than the sound of a running computer, so you should have no troubles sleeping in the same room as it.

Feature-wise, this dehumidifier is quite bare-bones. It has a timer, a filter, and multiple power settings. It doesn’t lack any critical features, but there are a number of features that would be nice to have. For instance, there’s no humidistat for automatically managing the humidity of a room.

Summary

The primary selling points of this product is the weight and the noise level. On both fronts, De’Longhi have certainly delivered. For a dehumidifier of its power, it’s both quiet and lightweight. If you’re looking for a dehumidifier that needs to be quiet and portable, then the De’Longhi Compressor Free Compact Dehumidifier might be the product for you.

 

Best Cheap Dehumidifier

After researching all of the inexpensive dehumidifiers currently on the market, we believe the Home Treats Portable Dehumidifier 12L is probably the best cheap dehumidifier you can get in the UK in 2017. Read on for a brief overview of what it can do and how it performs.

Home Treats Portable Dehumidifier 12L

Getting a good dehumidifier on a budget is tough. Of course, you could walk into the local store and pick up whatever they stock, but it’s unlikely you’ll leave with a good quality product. When dealing with a critical mould situation, it pays to spend a little extra and get a solid product. Home Treats have created a great quality dehumidifier that can be yours for under £100.

Of course, if you’re only after a dehumidifier for a small room, then definitely consider a mini dehumidifier as they’re far cheaper. The Pro Breeze 500ml Mini Dehumidifier is a great option. However, for dealing with more severe moisture problems, you can’t afford to go too cheap. The Home Treats 12L Portable Dehumidifier is a fine option if you need reliable performance on a budget.

Specifications

Dimensions: 54.4 x 34.4 x 22.8 cm
Capacity: 1.5 Litres
Weight: 11 Kg

Power and Features

For a budget option, Home Treats have really outdone themselves. This product comes with all of the features that are essential in a good dehumidifier. It features a humidity sensor, an air filter, a timer, auto shut-off, multiple fan speeds, and a nifty carry handle. For dealing with moderate dampness, it’s definitely sufficient.

Its power is certainly reasonable. But if you’re looking for a solution to a heavy moisture problem, then there are more powerful products available. For dealing with moderate moisture issues in a small house or apartment, you’re unlikely to have any issues. It pulls its weight and does it for considerably cheaper than many other dehumidifiers on the market.

Summary

If you’re after a no-frills solution to excessive humidity in a small apartment or house, then Home Treats have got the product for you. There are certainly cheaper products on the market, but going much cheaper will leave your choices to only mini dehumidifiers and low quality products.

Overall, the Home Treats Portable Dehumidifier is a solid dehumidifier if your budget simply can’t stretch to afford something with more features or more power.

 

Best Wall-Mounted Dehumidifier

After researching the market, we believe the EcoAir DCW10 Dehumidifier is probably the best wall-mounted dehumidifier in the UK in 2017. Read on to find out more about it.

EcoAir DCW10 Dehumidifier

When space is at a premium, putting a dehumidifier in a room will cost you valuable floor-space. For a more permanent and space-efficient installation, a wall-mounted dehumidifier is a great option. Once mounted to the wall, they work much the same as a free-standing dehumidifier and are a great choice for landlords as they’re far more difficult to accidentally break.

We recommend the EcoAir DCW10 Dehumidifier if you’re in the market for a wall-mounted dehumidifier. It’s quite powerful and comes with many useful features, including a splash-proof design for bathroom usage.

Specifications

Dimensions: 17.5 x 32.3 x 53 cm
Capacity: 2 Litres
Weight: 11 Kg
Power: 200W

Power and Features

The EcoAir DCW10 Dehumidifier is an impressive piece of kit. Whilst it’s far from the most powerful dehumidifier on the market, the features included make it a very good choice for rooms where space is at a premium. For instance, this dehumidifier is absolutely perfect for small bathrooms. It can be mounted to the wall, and it’s even IPX4 Rated splash-proof so you don’t have to worry about it getting damaged.

Included with the product is a splash-proof (IPX5) remote control that can be used to control the dehumidifier. This is ideal for when the unit is mounted somewhere out of reach. For instance, you could operate the remote control from in the bath, setting a timer to deal with the moisture from the bath so that you can simply walk out of your bathroom and leave the dehumidifier to do its thing. No need to return and manually turn it off

Another nifty feature of the product is the included charcoal filter that is used to deodorise a room whilst the dehumidifier is running, making it perfect for bathroom usage.

Summary

If you need a discreet, compact, wall-mountable solution to your moisture problems, then the EcoAir DCW10 is an excellent product. We think it’s a perfect fit for nearly any bathroom. Its splash-proof design is ideal for withstanding the rigour of bathroom life, and the charcoal filter is perfect for dealing with bathroom odours.

 

Best Large Dehumidifier

After researching the market, we believe the Meaco 20L Low Energy Dehumidifier is probably the best large dehumidifier in the UK in 2017. It’s also one of the best dehumidifiers with a humidistat. Read the review below to find out more about it.

Meaco 20L Low Energy Dehumidifier

Sometimes your moisture situation calls for the big guns. That’s when you need a large dehumidifier, preferably one that’s energy efficient as otherwise your electricity bill will cost a fortune. Luckily for you, Meaco have created a 20L energy-efficient dehumidifier that’s capable of dealing with the dehumidifying needs of an average-sized home.

Specifications

Dimensions: 38.5 x 59.5 x 29 cm
Capacity: 6 Litres
Airflow: 160m³/hour
Approx. Electricity Cost: 3.88p/hour based on 15.32p/kWh

Power and Features

When it comes to dehumidifying a whole home, you can’t afford to miss out on features. The Meaco 20L Low Energy Dehumidifier features a comprehensive list of features. The most important of which is the built-in humidistat to ensure that humidity is managed effectively without wasting power unnecessarily.

Speaking of power, this dehumidifier certainly delivers some. It’s not quite the most powerful dehumidifier on the market, but we think that this dehumidifier is in the power-to-cost sweet-spot. Finding the best large dehumidifier can be tough, but this product is certainly a strong contender.

The energy efficiency rating of this dehumidifier is also quite impressive. If you need the raw dehumidifying power that this dehumidifier is capable of, then the energy efficiency is a nice plus. However, there are less powerful models available that are more efficient.

Summary

Dealing with moisture throughout your home can be tough. It’s crucial that you pick a dehumidifier that will do the job quickly and efficiently. The Meaco 20L Low Energy Dehumidifier is a great product if you’re looking to keep your home free of mould. As far as large dehumidifiers with humidistats go, this product is an excellent choice.

 

Best Mini Dehumidifier

After researching the market, we believe the Pro Breeze 500ml Mini Dehumidifier is probably the best mini dehumidifier in the UK in 2017. Read on to find out more about it.

Pro Breeze 500ml Mini Dehumidifier

Excessive moisture in small areas can be difficult to deal with. A full-sized dehumidifier is too expensive to run just to keep a small kitchen damp-free. Finding the best small dehumidifier can be tough. That’s why we recommend the Pro Breeze 500ml Mini Dehumidifier. It’s a very compact dehumidifier that can easily deal with moisture in small rooms.

Specifications

Dimensions: 18 x 28 x 16 cm
Capacity: 500ml
Weight: 1.1 Kg

Power and Features

This dehumidifier is more than powerful enough to take care of moisture in small areas. It’s ideal for keeping mould out of a bedroom, caravan, wardrobe, or kitchen. It’ll suit your needs so long as the area is small. According to manufacturer specifications, it is capable of extracting 250ml a day, though in real-world conditions, that number is likely to be lower.

Due to its small size, it lacks any way to automatically dispose of collected moisture, so it has a 500ml tank that can be emptied. That tank should last 1-2 days before needing to be emptied. As such, this dehumidifier is fairly low-maintenance. It does lack a humidistat, so you will need to manually switch it on and off.

Summary

In short, the Pro Breeze 500ml Mini Dehumidifier is an excellent product. It’s extremely compact and more than capable enough to deal with your moisture problems. All-in-all, we think it’s one of the best mini dehumidifiers on the market.

 

Best Portable Dehumidifier

After researching the market, we believe the Inventor C2-12LBS Dehumidifier is probably the best portable dehumidifier in the UK in 2017. Read the review below to find out more about it.

Inventor C2-12LBS Dehumidifier

Dehumidifiers only work effectively in the room they are placed in. As such, choosing a portable design is imperative if you want a single dehumidifier to deal with moisture in many rooms of your house. The Inventor C2-12LBS Dehumidifier is a reasonably powerful dehumidifier with very convenient wheels on the bottom, allowing you to easily wheel this product between the rooms of your house.

Specifications

Dimensions: 30.8 x 24.7 x 45.6 cm
Capacity: 2 Litres
Weight: 11 Kg

Power and Features

Finding the right balance between portability and power can be tough. Thanks to the wheels on the base of this product, it can get away with being slightly heavier whilst still retaining easy mobility. It can be easily wheeled around your home to deal with high humidity rooms that a larger and less portable whole-home solution would struggle with.

Another excellent feature of this product is the “silent mode” which makes it perfect for use in a bedroom. Simply turn on the silent mode and the unit will continue dehumidifying throughout the night. The downside of this is that it is less effective in its silent mode, so it’s important that it does not get left in silent mode permanently.

For a portable dehumidifier, it is quite powerful. Its power is more than sufficient for dehumidifying small homes or apartments. If you leave the Inventor C2-12LBS in a central location in your home, it can prevent mould throughout the home. However, in cases of high moisture levels, you might want to consider a more powerful dehumidifier or getting a PIV unit installed.

Summary

For portability, the Inventor C2-12LBS is impressive. It offers solid performance and very simple portability. You might struggle a bit with stairs, but for wheeling between high-moisture rooms on the same floor, it’s a great choice. As a nifty bonus, its silent mode makes it a very good option for bedroom or night-time usage.

 

Best Whole House Moisture Treatment – PIV Unit

Dehumidifying a whole house is tough. Whilst it can be certainly accomplished using a traditional dehumidifier, like one of the many dehumidifiers reviewed in this post, a PIV (Positive Input Ventilation) unit might be a better solution.

What is a PIV Unit?

PIV units work by drawing the air from an attic, filtering it, and then pushing it through the rest of your home. In essence, this creates a continuous flow of air around the home that draws moisture up from fabrics and pushes it out of your home.

Advantages

PIV units are very effective at removing moisture from a home. By simply pushing damp air out of your home, there’s no need for the expensive process of removing moisture from the air. This makes PIV units impressively cheap to run.

In addition to being cheap and effective, they’re also extremely convenient. Once a PIV unit is fitted, it can be simply left to do its thing until it needs to be serviced. This means, once installed you may only need to touch it once a year to change the filter. By installing a PIV unit, you get a permanent boost to the air quality in your home, without the need to deal with emptying out water tanks or switching the thing on and off.

Disadvantages

Unfortunately, there are a number of disadvantages to PIV units. The primary being that it has a complex installation process. Unlike a dehumidifier, which simply needs to be plugged in, a PIV unit requires some level of DIY skill to install. It’s not overly complicated, and with minimal DIY experience you could probably manage it by following a few tutorials.

Another disadvantage is that their effectiveness is entirely reliant upon air quality in your attic. If you’ve got excessive moisture in your attic, or other stuff you don’t want blown throughout your property, then you’ll need to undertake a potentially expensive set of repairs to prepare your attic for installation.

Summary

As a whole house solution to moisture problems, a PIV unit is the way to go. It is capable of reducing moisture throughout an entire home far cheaper than a whole house dehumidifier unit. They are incredibly effective at reducing humidity and increasing air quality throughout a whole home.

For additional information on PIV units, check out FixMyRoof’s post on them, including a handy installation guide.

 

How to Choose a Dehumidifier

Dehumidifiers are used for different purposes, which is why there are several different kinds of dehumidifier available. Some are used strictly for removing the humid air from the house, others also act as air conditioners, others are designed for heath purposes, and others combine several of these functions.

When you’re looking to purchase a new dehumidifier, you need to make sure you’re buying one that fits your needs and budget, and is well made and high quality. You want something that is neither too cheap nor overpriced.

Dehumidifiers can be very efficient at removing humidity, but you want one that will keep humidity at the right level rather than removing all of the humidity from your home.

Here are some of the key things to consider when choosing a dehumidifier.

Speed

If you want fast results, you should look for a dehumidifier that starts working quickly and can remove a large amount of water from the air each hour.

Compressor or desiccant?

If you’re looking to use a dehumidifier at higher temperatures and higher humidity levels, you’ll need a refrigerant or compressor dehumidifier. It will be a better choice for a home because it draws in the bad air over a filter and then passes it over cold coils. The water will then condense on the coils and drip into the water tank.

If you are going to have this type, or any type of dehumidifier switched on for a long time, make sure to purchase one with a large water tank, so it will collect a lot of water.

Next, there’s the desiccant dehumidifier, which is designed to work more effectively in colder temperatures, such as a garage or a conservatory. These dehumidifiers absorb material and extract water from the air, and then the material is heated so the moisture will drip into the water condenser.

Desiccant dehumidifiers are very efficient in cold temperatures and work fast to condense the water and heat the material. However, these dehumidifiers typically use more energy, which isn’t good for your electric bill even if it is good for your home. They consume more energy because of the way the material is heated, which is an extra step.

Size

When you’re deciding which dehumidifier to pick, remember to consider size too. Dehumidifiers usually have a capacity ranging from 0.5 litres to 20 litres. A small room will only require a smaller capacity, but the larger the room, the higher the capacity you should pick—it will mean you can keep it on for longer periods of time.

It’s important not to confuse the water tank capacity with the amount of moisture a dehumidifier can extract from the air each hour or each day. You should look at both of these statistics to make sure you’re getting a dehumidifier with decent extraction capabilities and a good water tank size. You should be sceptical of the figure given for the amount of water a dehumidifier can extract per hour or per day, as dehumidifiers often perform worse in practice.

Extra features and functions

Some models have a frost watch option, which is helpful, because it has the ability to prevent the water from freezing on cold coils when the water is pulled from the air.

Some use humidistat options, which monitor the moisture in the air so it can turn itself on and off to maintain the humidity level you’ve selected. This option is perfect for everyone because it will not pull too much water from the air, which will have a reverse effect. And, you don’t have to monitor the dehumidifier all day and make sure it’s not pulling too much water, because who can actually tell.

Make sure to look for dehumidifiers with wheels, too, because they can be moved easily. Some dehumidifiers are very heavy and bulky, so if you purchase one on wheels, you’ll be able to move them around, which will allow you to dehumidify multiple rooms throughout your home or office.

Price and running costs

Dehumidifier prices are based on lots of factors including features, capacity, power and brand name. In order to save money, only buy a dehumidifier with the features you need rather than going overboard and getting a dehumidifier that is more powerful or advanced than you need.

You can also save money by going for a less established brand, but you need to be more careful as their products may be less reliable.

Dehumidifier FAQs

Dehumidifiers are appliances that remove excess moisture, otherwise known as humidity, from the air inside a home. There are many benefits to using a dehumidifier, ranging from improved health conditions to helping with the preservation of hardwood floors, walls, and other structural components that are sensitive to moisture.

Is a dehumidifier right for your home? Here are some common questions that you might want to consider:

Do dehumidifiers actually work?

Dehumidifiers are quite effective at removing excess humidity. In order to separate the moisture from the air, the machine draws in the warm, moist air using a fan. Then, the air passes over pipes through which a coolant circulates continuously in order to bring down the temperature.

As the air cools, the liquid water separates from the air and drips into a collection receptacle. Then the air is then reheated to the desired temperature and recirculated into the home.

What are the health benefits of using a dehumidifier?

Excess moisture in the air can cause a range of health issues, specifically those that affect the respiratory system. Think about going outside on a hot, humid summer day—your breathing probably feels constricted and uncomfortable. This goes for just about anyone in high humidity, but people who are especially young, elderly, or have breathing conditions such as asthma or COPD are especially affected.

Installing a dehumidifier can help improve the breathing conditions in the home when humidity is high. Additionally, excess moisture in the home can lead to the accumulation of allergens such as dust, mold, and mildew. Using a dehumidifier will help make the environment less suitable for allergens to grow and affect your health.

What are the household benefits of using a dehumidifier?

Humidity can cause wood to absorb moisture, resulting in swelling. Over time, this can affect the integrity of important structural components of a home, such as hardwood floors. Using a dehumidifier can help maintain an appropriate level of dryness in the home to preserve such materials.

As stated earlier, mold and mildew grow in humid environments, which can also result in unpleasant odors in your home. These can be avoided by removing excess moisture with a dehumidifier.

Additionally, if you have ever noticed fog accumulating on your windows, this is a sign that you may have excess moisture in the air. Using a dehumidifier can help reduce this annoying problem and save you some time that would otherwise be spent cleaning windows.

Another household benefit you’ll notice by using a dehumidifier is that your air conditioner will be more efficient (if you have one). By reducing the amount of moisture in the air, your air conditioner will do less work bringing the temperature down to a comfortable level in warmer seasons.

Do dehumidifiers cool the air?

The short answer is no, a dehumidifier will not cool your home. However, keep in mind that much of the discomfort that comes from the summer heat is due to the high humidity level. By reducing the amount moisture in the air, a dehumidifier will make the home feel more comfortable in the summer regardless of the temperature, which will ultimately reduce the amount of work your air conditioner will have to do.

Is it expensive to buy and maintain a dehumidifier?

The initial cost of a dehumidifier will depend on your specific needs. Dehumidifiers for small spaces such as wardrobes and small bathrooms can cost less than £50. More powerful dehumidifiers for small rooms will cost £50-£100. Units for larger spaces such as cellars will cost over a hundred pounds. Dehumidifiers for larger buildings can cost over £500, and for commercial businesses, you might expect to spend several thousand pounds.

As for maintenance, different units will have different requirements. Some require that you empty the receptacle that collects water, for example, while others are self-draining. These differences will affect the cost of the unit as well.

Most household units are fairly simple to maintain, requiring only occasional filter changes and removal of excess dust and debris. A well-maintained unit can be expected to last several years.

Do dehumidifiers use much electricity?

As with any appliance, dehumidifiers come in a range of sizes and capacities, which will affect the cost of operation. Before purchasing a dehumidifier, think carefully about the size of the space that the unit will be expected to handle, the humidity level within that space, and the cost of electricity in your area. Choose a humidifier that can appropriately handle the size of the space and the moisture level, preferably without running constantly.

Will running a dehumidifier increase my electric bill?

The cost to run a dehumidifier will depend on many factors. You can calculate the approximate amount of money you’ll spend by estimating the amount of time the dehumidifier will run each day, the kilowatts used per hour by the machine, and the rate you pay per kilowatt-hour.

For greater savings, consider an energy-efficient dehumidifier, such as one that is Energy Star rated. Also keep in mind that having a dehumidifier can save on long-term costs such as allergy treatments, cost of running air conditioning in hot, humid weather, and repairing structural damage to the home caused by high humidity levels, mold, and mildew.

Do dehumidifiers help dry clothes?

By reducing the humidity in the air, dehumidifiers can help dry clothes faster. Drying clothes by hanging them in a room with a dehumidifier is preferable to drying them using a radiator or another appliance with a heating element for several reasons.

First, heat will cause the moisture from the clothing to evaporate and become trapped inside, which can lead to even higher humidity levels. Not only will this cause the home to become uncomfortable, but it can lead to the health and household hazards of excess moisture discussed earlier.

Additionally, clothes will dry much more slowly in a humid environment, so using a dehumidifier will be more efficient compared to a heater.

Conclusion

Now that you know the benefits and limitations of dehumidifiers, you can make an informed choice about whether purchasing one will be a good investment for your specific needs.
