Beat Dampness With The Best Dehumidifiers
Ever heard the joke, "does breakfast cereal come pre-soggy in your area?" Yeah. These folks are usually referring to high humidity. Fortunately, it is not something that you have to live with. Unless you enjoy it - in that case, you can go for a humidifier instead.
If you've walked into a room only to be hit by a musty smell of mildew, you may have to invest in a high-quality dehumidifier. These appliances draw excess moisture from a room and make it comfortable. Eliminating excess humidity helps you alleviate allergies, odours, and dampness that can ruin a home.
But which unit should you pick? Well, we've done the work, so you don't have to. With our buying guide, you’ll be able to learn more about these essential air quality improvement accessories. Take some time to look through the features to consider, where to install the device and more below!
What are Dehumidifiers?
A dehumidifier is an electric household appliance that pulls excess moisture from the environment. This process is known as dehumidification. It should not be confused with a humidifier which does the opposite.
There are four types of dehumidifiers. These include compressor, desiccant, absorbent salt-based, and Peltier models.
Most households use compressor dehumidifiers. They have a fan, which pulls air from its surroundings and into the unit. The air is condensed in the dehumidifier coils. Then, it's reheated and released back into the room. However, the moisture collected remains on the coils and drips back into the water tank.
Why Do You Need a Dehumidifier?
Hot and humid air is uncomfortable, if not annoying. Your home can always benefit from such a device. If you’re interested in learning more about the benefits of a dehumidifier, we have a dedicated article going more in-depth about it. But, we’ve also added some of the most advantageous reasons that we recommend you invest in one right down below.
1. They Make Rooms Less Sticky.
Have you noticed your skin gets sticky more often, and you get frizzy hair? Excess air moisture is the culprit. But with a dehumidifier, you can enjoy a more relaxed atmosphere in the whole house. Plus, you never have to break into a sweat without exercising. This is more so in the hot months or if you live on the coast. Who doesn’t love a high-quality moisture removal assistant?
2. They Prevent Mould and Mildew.
Some telltale signs that your home needs a dehumidifier include mould buildup, black spots, and crumbling paint. Dehumidifiers maintain optimal humidity and temperatures, making it impossible for mould and mildew to grow. As a result, you won't deal with mould on furniture, curtains, walls, bed sheets, and clothing. Also, if you invest in a portable dehumidifier, you can bring it from one area to the other and tackle each room efficiently.
3. They Remove Allergy Triggers.
Common allergens like dust mites and other particles live in a humid environment. So, if allergies are making you miserable, it could be that your living space is damp. Employ the help of a dehumidifier to alleviate allergies and respiratory problems.
Besides, some units include a powerful air purifier that removes dust and kills bacteria on contact. Also, they may come with a HEPA filtration system that can give you peace of mind that all airborne allergens are captured with more efficiency.
4. They Can Lower Energy Costs.
First, some units are energy star dehumidifiers. At the same time, energy-efficient dehumidifiers help HVAC systems run more efficiently. It means they use high-quality components that allow the appliance to use as little energy as possible. So, in the hot, humid months, your air conditioner won't have to work as hard as when the dehumidifier is absent.
To gain a better understanding, a heavy-duty 30-70 pint energy star dehumidifier can work fantastically in large or small rooms, eliminating the need for air conditioning when it’s sticky and uncomfortable around the house.
What to Look for When Buying a Dehumidifier
Whether you're looking to improve the air quality of your home or want to restore the structural integrity of your office, you'll find a dehumidifier for your needs. The following things to look for will help you pick the ideal model.
The unit you pick should fit the space that you intend to use it. Most are rated at a specific pint capacity based on relative humidity. However, they are affected by the size of the area used. In that case, you will need to know the size of the room and your area's humidity.
Households and residentials can use models as big as 70-pint dehumidifiers. Such appliances can maintain humidity levels in areas as large as 111 sq. meters (1200 sq. ft).
On the other hand, 30-pint dehumidifiers are small models ideal for rooms sized 50 sq. meters (500 sq. ft.). This can be a large living room or a small space.
2. Tank Capacity
Dehumidifiers collect water in a reservoir within the unit. A high capacity dehumidifier means the less often you're going to need to empty it. Still, a model that can collect lots of pints of moisture and hold most of it will be pricier.
You'll want to consider a dehumidifier model with a tank that allows for continuous use. This way, it's going to prevent filling a room with water. And it's better when it has an automatic shut-off when the tank is full. The amount of water it can hold will depend on the tank’s litre capacity, with options ranging from 500ml to over 5L.
This feature is not a must. But it's very convenient. Some brands like Inventor have a gravity-fed drain hose that can feed into a bucket or outdoor drainage. You can easily use it in the bathroom for continuous drainage. Others like Homelabs have a pump that can drive water upwards into a window or sink. Such models are ideal for the cellar or basement, where you can easily forget to drain the tank.
4. Easy Set-Up
Some dehumidifiers can weigh upwards of 12kgs. Transporting them can put extra strain on your back if you lift them. To this end, you'll want to choose a model with smooth-rolling casters and a sturdy, comfortable handle. Ergonomics are not only important for your wellness; they’re also better equipped for your appliance’s longevity.
5. Noise Level
Compressors and fans in a dehumidifier produce noise continuously. It's best to have two fan speeds or a model that generally has a low noise level. These units are convenient if you use one in your bedroom. The least noisy dehumidifiers have a noise rating of 30-45dB.
6. Automatic Sensor
You'll want a user-friendly model for simple control of humidity in your home. To this end, it's nice if your dehumidifier includes a humidistat. This instrument measures humidity and relays the information back to the dehumidifier. It allows you to set the desired humidity, which the dehumidifier works to maintain.
If yours does not come with this feature, you can invest in a hygrometer. It does the same work of measuring relative humidity. As such, you can place it next to the dehumidifier, and you'll know when to turn the appliance off.
7. Laundry Mode
If you dry your clothes indoors, a turbo mode will come in handy. So will a tumble dryer, but a dehumidifier can be a multipurpose investment if your budget is tight. This mode increases the fan speed so that the air in the laundry room is drier. It reduces moisture levels immensely. So, clothes dry faster without you having to rely on other gadgets such as, say, heated towel rails.
8. Humidity Controls
Automated controls on the dehumidifier should be on a well-lit control panel. Considering that you may be using it in the basement or cellar, where it's often dark, you should easily see the controls day and night. It's also nice if a dehumidifier can connect over Wi-Fi. This means you can control it on your phone via its app. The Frigidaire, smart, 50-pint dehumidifier is the perfect example of a Wi-Fi-enabled model. Some even come with unique LED colours that indicate when the appliance requires your attention.
9. Automatic Off & Auto Restart
A good dehumidifier switches off automatically when the desired humidity is reached. It will also restart when room humidity levels exceed the selected settings. Others have an auto-restart after a power outage for ultimate energy efficiency. This type of dehumidifier goes back to pre-set settings before power loss. Such a feature is essential to conserve energy, save money and lower your electricity bills.
10. Defrost Feature
This feature allows the dehumidifier to operate at low temperatures. If used in the basement or crawl space, the heat exchange coils can frost over when temperatures dip below 18 degrees Celsius. So, there's a high risk of damaged coils.
Although models with an auto-defrost feature are pricier than those without, you will enjoy them as a long-term investment well worth the extra few pounds.
11. Air Filter
An air purifier is another feature that's not a must-have. But when present, it removes allergens and prevents coils’ damage from dust. Still, we advise you to go for one that has washable filters. It means you'll replace the filters less often.
How Long Should You Leave Your Dehumidifier Running?
A good rule of thumb is to run a dehumidifier for 12 hours a day. This is if your unit is correctly sized for your room and humidity levels. But if you often change the unit's location, the room size and dampness level will affect its efficiency. Other factors, including the unit's capacity and running cost, will affect how long you need to run it for.
So, if the room is exceptionally wet, you will need to run it for the whole day. Such a dehumidifier needs an auto shut-off feature or a 24-hour timer. It helps to turn off the unit when it achieves desired humidity levels.
Also, it's good to connect the dehumidifier to a continuous drain if it runs for 24 hours.
Where Can You Keep Your Dehumidifier?
The best location for your dehumidifier is in the room you need it most. Dehumidifiers are common in the cellar, basement, bathroom, laundry room, kitchen, crawl spaces, or indoor pools. These areas are often the dampest spaces in most homes. But, the choice is yours, and you should consider it according to your home’s needs.
How Much Should You Spend on Dehumidifiers?
Do you want to ensure that you find a model that fits your budget? Luckily, there are many options to choose from fit for any pocket, from low-cost to luxurious kinds. We’ve broken them down into three price points so that you can find the one you’re most comfortable spending-wise.
These are small dehumidifiers ideal for a bedroom, garage, kitchen, or small apartment ranging between £25-55. Pro Breeze is the most recognisable brand. But others like UGHEZZ also sport their mini models. These units feature smaller tanks, mostly 500ml and below. But, if you’re living on your own or are tight in space, these are excellent starting points.
A portable but medium-sized dehumidifier is considered to have a 5L-10L dehumidifying capacity. These are priced between £60-100. They are more versatile than mini dehumidifiers since you can use them in basements and cellars. But, they may lack features such as defrost function, humidistat, and mobility casters.
These are top-of-the-line models with all the desired features in a dehumidifier. We are talking about automatic controls, inbuilt humidistats, defrost, high dehumidifying, and large capacity tanks. These models typically cost above £100. But because of their effectiveness, they are what you will find in most homes.
