Dehumidifier for Basement Buying Guide and Reviews- 2022
Basements located below ground level tend to absorb moisture from the surrounding soil, making them damp and moldy, leading to the growth of mold and mildew. You probably know that inhaling mold spores can lead to respiratory disorders and allergy sufferers. Still, you may not know that high humidity can damage furniture and other items stored in the basement.
Humidity levels also affect your comfort. Ideally, they should be between 30 percent and 50 percent; if it is higher, you are likely to feel cold or sweaty (depending on the temperature) because humidity inhibits the evaporation of sweat.
Read on if you’re looking for a device to remove excess moisture from the air. You’ll learn to choose the best dehumidifier for your basement (as well as other areas of your home) and get the lowdown on our top picks.
The three types of Dehumidifier for Basement
Dehumidifiers work in different ways, with some methods being more suitable than others for the high humidity levels found in basements.
• Compressor dehumidifiers: Most dehumidifiers use a compressor to operate a fan that draws air over cold coils, causing moisture to condense (as droplets on the outside of a cold drink). The droplets then run into a tank, emptied regularly, or into a floor drain via a drain hose. Compressor dehumidifiers are the best dehumidifiers for basement moisture.
• Desiccant dehumidifiers: In this dehumidifier, moist air is drawn through a filter made of a desiccant material. It traps the moisture, which then drips into a collection tank. Desiccant dehumidifiers can control humidity levels in small rooms above ground but may not be powerful enough for basements.
• thermo-electric dehumidifiers: It is known as “Peltier dehumidifiers” after the physicist Jean Charles Peltier, who discovered the thermo-electric method of extracting moisture from the air; these units work by drawing moist air along the surface of small heated surfaces (called “sinks”) where it collects and then drips into a collection tank., Thermoelectric dehumidifiers work best in warm rooms and are often on the small side, so they may not be the best choice for a large basement or fresh.
Dehumidifier for Basement- Capacity and Cost considerations
Dehumidifiers are rated by capacity (how much water they can remove from the air per day.) Although labeled “small, medium, and large,” this refers to their power, not the size of their collection tank., Collection tanks have a capacity of between one and three gallons, and as a general rule, the more influential the dehumidifier, the greater its power. A large capacity dehumidifier is necessary to eliminate the high humidity level present in many basements.
• Small Capacity: These lightweight, portable, affordable units ($45 to 990) collect an average of 15 to 30 pints of moisture per day. They are very suitable for small rooms or closets.
*medium capacity: Capable of collecting 30 to 45 pints of moisture per day, medium-capacity dehumidifiers work well in medium to large-sized rooms but may not be powerful enough for a basement. They cost between 1,115 and 2,200.
• Large Capacity – With the ability to remove up to 75 pints of moisture per day, a large capacity dehumidifier is the best choice for a basement. Expect to pay between $180 and $300.,
Dehumidifier for Basement- The noise factor
Dehumidifiers generate a noise similar to the hum of a window air conditioner, and the higher the capacity, the louder the device. Most dehumidifiers produce between 53 decibels (comparable to the usual conversation) and 65 decibels (comparable to the sound of traffic on the street). Still, manufacturers are not required to list noise levels on their units. Reading customer reviews is the best way to determine how loud a dehumidifier will be. (Tip: To reduce noise, make sure your dehumidifier sits on a level surface.)
Dehumidifier for Basement- Drainage decisions
All dehumidifiers come with collection tanks, but some models also connect a drain hose (usually a standard garden hose) to direct collected moisture into a floor drain. The unit will automatically shut off when the collection tank is full, so if you can’t empty it daily, you should probably buy a team with a drain hose. Keep in mind that a pint weighs about a pound, so while a large capacity dehumidifier can collect up to 75 pints a day, tanks typically hold up to three gallons to allow for easy and frequent emptying, only the most potent bodybuilder would want to haul a 75-pound collection tank around!
Concerns about energy consumption
Operating a large capacity dehumidifier costs an average of $115 to $550 per month, depending on your utility rates, the size of your basement, and humidity levels. Although today’s dehumidifiers are more energy-efficient than a decade ago, it’s wise to look for the Energy Star label when shopping. These models are the most efficient and could save up to 30 percent on energy consumption compared to a standard machine.
Dehumidifier for Basement- Several useful options
All dehumidifiers allow you to choose a bare, normal, dry, or very dry humidity level, but some have additional features you may find helpful.
div• * digital controls allow you to select the desired humidity level by percentages, such as 35 percent or 45 percent humidity. The unit will automatically turn off when the moisture in the room meets the preset station and then turn back on as needed.
div• * a timer that you can set to automatically turn the dehumidifier on/off at a predetermined time, so you don’t have to do it manually.
• an automatic restart function to turn the unit back on after a power interruption, such as a power outage.,
* an easy-to-carry collection tank with comfortable handles and a well-designed spout that allows you to discharge water without spillage.
div• * a frost sensor to detect frost buildup and turn off the machine to save energy. When a compressor unit runs for long periods, frost can develop on the coils, reducing the effectiveness of the dehumidifier. So while a team with frost buildup will continue to run, it will no longer effectively remove moisture from the air. Some models also have a reset feature that turns the unit back on after the coils have thawed.
Buying guide for the best Dehumidifier for Basement
Moisture is not just a basement thing. Many people have to share several places in the house with her or even the bedroom for various reasons. It is impossible not to get fed up with that familiar sticky feeling and stinky smell when this happens.
Above 65% relative humidity, the human body can negatively affect, and the risk of mold growth increases.
Of course, they are not healthy conditions for you or your family.
The solution to getting rid of this danger is to acquire a dehumidifier. But we know that the number of brands, models, and versions on the market can generate some doubts when choosing the most appropriate model.
In this guide, we give you the keys to answer for yourself many of the questions that may arise.
Who should use a Dehumidifier for Basement?
→ Anyone wants to correct or prevent respiratory tract conditions, such as asthma or chronic rhinitis. The microbial load of the air inhaled in humid environments can worsen the symptoms of these ailments or even cause them to appear for the first time.
It especially recommends for pregnant women and people with a weakened immune system, whether or not they suffer from previous respiratory problems.
→ Those who by medical prescription need to prevent the appearance of molds and fungi since these represent a real danger and are capable of causing severe problems. A contaminated space can cause, in addition to respiratory diseases, allergies, heart rhythm disturbances.
Mold contains harmful micro-components, such as spores, that travel through living space and spread uncontrollably through the air.
In addition, the smell is more than unpleasant, and the stains adhere to the wall suggest a lack of hygiene or poor or non-existent cleaning habits.
Moms and dads are concerned about the health of their little ones
Children are susceptible to changes in the atmosphere that occur and can get sick in the blink of an eye if the conditions of the space in which they sleep and play are not optimal.
Even when adults do not perceive humidity, it affects them. Mites, bacteria, and fungi grow thanks to it, float in the air, and breathe in babies and children. Some of the symptoms can be watery eyes, stuffy or runny nose, sneezing, coughing, itching, wheezing, trouble breathing, headache, and, in some critical cases, even asthma attacks.
→ Older adults who are at risk of lung infections: As with children’s health, the health of the elderly is also incredibly delicate.
It is convenient to provide a suitable temperature and a sufficiently dry environment to protect them from bronchitis, pneumonia, pain, and sensitivity in the bones.
→ Anyone who wants to take care of, in addition to the health conditions, the house itself, and the furniture: In places with high humidity, the table can quickly affect.
Various materials such as upholstery, cork, foam, metals, or wood (it raises the plywood and deforms the parquet) suffer significant deterioration when exposed to excessively humid environments.
→ The owners of buildings in which construction or renovation has been carried out; Materials such as cement, plaster, or paint are fresh and need to reach the right dryness level to set well.
The three most essential benefits of Dehumidifier for Basement
- They reduce high humidity levels, which, as we have seen, can link to many respiratory problems. This fact is medically prove.
- Excessive humidity creates a perfect breeding ground for dust mites that live in furniture, carpets, and bedding. These dead mites and their droppings are a symptom trigger for respiratory conditions. Reducing humidity with a dehumidifier helps kill dust mites and prevent them from becoming airborne triggers, improving the air quality you breathe.
- They prevent mold from developing. Poor ventilation, leaks, and high humidity cause this common problem in many homes.
- Black mold, which is the most toxic, can find the conditions to grow from 50% humidity. At higher magnification, fungi proliferate uncontrollably and pose an increased health risk to humans and pets.
- Get rid of condensation. It usually appears inside the windows in the morning when you wake up. It is an unmistakable sign that the room has humidity problems.
- The water vapor that the air contains turns into a liquid state in contact with a cold surface, the glass (but it can also be the tiles). It is how a film of water creat that negatively affects all adjacent areas. Stains on the walls, discoloration, chips, swollen wood, peeling aluminum, rust.
What to look for when buying a dehumidifier?
The relationship between extraction capacity, relative humidity, and ambient temperature
A common mistake is to think that the absorption capacity is equal to the power of the tank. However, it has nothing to do with this but with the relative humidity and temperature of the room.
Simply put, relative humidity is the amount of water vapor in the air. The higher the relative humidity, the greater the effort of the device to lower the levels, the more power and ventilation it needs to achieve it.
On the other hand, the temperature also influences a lot. Hot air admits more water vapor. Therefore, relative humidity is higher (and more difficult to eliminate) in cold environments than in warm ones for the same amount of water vapor.
High humidity is also very annoying in summer. It happens because the evaporation of sweat is the primary means of dissipating body heat, and high ambient humidity makes this function difficult. Hence, you experience a more elevated temperature thermal sensation.
Dehumidifier manufacturers typically measure dehumidification capacity using 80% relative humidity and 30° temperature parameters. But, for example, if a specific model can absorb 10 liters of air under these conditions, it must consider that its effectiveness will decrease if the relative humidity is higher or the temperature is lower than those indicated.
Dehumidifier for Basement- The place where you need it
We have already seen that humidity can appear in countless places where it is not welcome. But, is a baby’s room the same as a laundry room, a wine cellar, or a shoe cabinet?
Each room has its peculiarities: a children’s room is usually tiny but more significant than the laundry room. However, we will require a very quiet device in the first, while in the second, that aspect can give us completely the same.
When the problem spreads throughout the house, there is nothing to do with a small device. It would help if a powerful team quickly moved between different rooms.
If, for example, it is a greenhouse or a food store, using a hygrometer will be essential.
Geological and climatological conditions
In the same way, we have to observe the geological and climatological conditions. Is it freezing in winter? Then it becomes essential that the dehumidifier has an antifreeze system. Does it rain often, or are you close to the coast? You will need more power.
Dehumidifier for Basement- Design and size
It may seem trivial, but it is not. Our house is our refuge, our favorite place in the world. We take care of its furniture and decoration with care and detail to make us feel comfortable. Sincerely, we also value the design of the appliances we buy.
It is even more so when its scope of action is not limited only to the kitchen. We are talking about a machine that is usually of considerable size.
The dehumidifier goes out to the living room, the entrance hall, and even the bedrooms. Therefore, a current and pleasant aesthetic will combine with the rest of the environment (or, at least, go unnoticed).
Dehumidifier for Basement- Clothes drying
Clothes sometimes seem to take ages to dry, and when they do, they’re left with a musty smell. It usually happens in winter, when the air is cold and does not admit more water vapor.
If this situation is too familiar to you, you should choose a multifunction dehumidifier model with clothes drying.
The instructions are simple:
- Hang the garments in a ventilated, small and well-closed place.
- Place the appliance just below and select the mode for laundry drying. If you don’t have a small space, you can use plastic on top of the clothesline to increase its effectiveness.
- Make sure the air inlet and outlet are clear.
This function uses the fan in fast mode and keeps the humidity around 20%. The clothes will dry much quicker and without odors.
Air purification– Dehumidifier for Basement
Many models include this property, but what is it? In addition to dehumidifying, cleaning the air of particles, thus avoiding the conditions that we have previously mentioned.
They are also instrumental in places with the presence of pets since they release hair and dander that we end up breathing.
HEPA is a high-efficiency air filter, although it is not the only one that can ensure high quality. Many innovative materials, such as activated carbon, manufacture air filters today.
When your appliance is equipped with removable filters, it is essential to sanitize them regularly. Some can wash under the tap; others can brush, vacuumed, or even immersed in some disinfectant product.
Dehumidifier for Basement- Maintenance cost
A dehumidifier does not involve any installation. However, there is a maintenance cost.
For starters, power consumption. We recommend that you choose a refrigerant dehumidifier (with a condenser) because they use less and are also cheaper than the desiccant type.
Concerned about consumption; it is best to invest a little more in a model that allows automatic on and off. You will save much more energy than with manual-only models.
If the filters are not washable, it is advisable to determine the price of the spare parts and how many hours of operation they must replace with new ones.
The investment involve in acquiring a good dehumidifier will quickly amortize by multiple factors:
- Savings in heating: since it is considerably more expensive to heat humid air than dry air. It can lower two or three degrees when the relative humidity is reduced to normal parameters (45-65%).
- Savings in-home repairs: due to material damage caused by humidity. Windows, walls, ceilings, floors, finishes, and joints.
- Savings in furniture, fixtures, and new clothes: when you have to get rid of those that humidity has damaged.
To give you an idea, we have made an estimated calculation on two of the models analyzed in this guide:
The 16 liter model of De’Longhi AreaDry DNS65 consumes 520 w/hour; this means that at the price of the KW/hour. If we use it for 4 hours a day, we will obtain a cost of approximately $51 /anus.
In other words, depending on its power, a dehumidifier can increase the electricity bill between €0.90 and €7.5 per month. Considering the benefits it brings us, we believe that this may be an expense well worth it.
How to use a dehumidifier and get the most out of it
- Has the mold already appeared? Please clean it before you start using the dehumidifier. Use a mixture of water (3/5 parts), detergent (1/5 interest), baking soda (1/5 part), and a splash of bleach. Also, wash clothing that gives off a bad smell.
- With continued use, you will see that the mold does not come back. The walls, furniture, and clothes remain clean and deodorized.
- Never place the appliance next to a heat source (radiator, stove, oven, fireplace.).
- Make sure it doesn’t get wet. Temperature and water affect the humidistat that some dehumidifiers have incorporated. This meter will not function properly if actual ambient conditions are involving.
- If you use the drainage system: Always remember to place the device on a higher surface to allow the water to drain through the hose smoothly.
- These devices are designed to use continuously for many hours. But if you think you can forget to turn it off when you no longer need it. It is better to choose a programmable model with a timer. In this way, you will take care of the compressor motor and extend its useful life.
Dehumidifier for Basement- Instructions for use
- Always consult the instructions for use and keep the filters clean to ensure optimal performance of your dehumidifier.
- To help the dehumidifier, carry out small daily actions such as: keep the house sufficiently ventilated, putting the heating at a maximum of 23°, closing doors and windows before using it, do not drying wet clothes on the radiators, and covering pots and pans when cooking.
- A dehumidifier will dry the environment and, depending on the model, improve the air quality, but you must bear in mind that it will not attack the root problem.
Strengthen moisture prevention
Make the necessary reforms to eliminate leaks, filtrations, or soaking. It is a worthwhile investment. After the work, continue to use the dehumidifier to strengthen moisture prevention.
We trust that this information has cleared many doubts, and now you are one step closer to feel truly comfortable at home.
It is clear: it is a versatile and functional appliance that surprises its good results.
