The condensing dehumidifier, also called a compressor dehumidifier, is the most common choice. It passes humid air through a filter and then condenses it. The water from this condensation passes into the tank and the dry air is released into the house. This system is recommended if you are dehumidifying large rooms. The air dryer or absorption dehumidifier uses silica gel, known for its absorbent properties. This substance will retain the water and evacuate it to the recovery tank. This type of dehumidifier is very effective in low temperature conditions.Finally, there is the thermoelectric dehumidifier or Peltier dehumidifier. This device uses 2 conductive plates to generate a temperature difference. The humid air drawn in passes near the hot plate, then the cold plate. Thus, the collected steam becomes water. Ecological and cheap, it is suitable for small areas.
Expressed in liters per day, the extraction capacity is defined as the amount of water absorbed by the dehumidifier in 24 hours. This indicator is often combined with the airflow rate, expressed in m³/h, to estimate the volume of the room in which the dehumidifier can serve. The size of an air dehumidifier's tank will depend on its extraction capacity. Some units may have a large extraction capacity, but a small tank. In this case, a drain hose allows for continuous drainage. Or a lifting pump for a high evacuation.
Most dehumidifiers are equipped with an automatic hygrostat. This is a group of sensors that control the humidity level in the ambient air and adjusts it to between 45 and 60%, the ideal level in a house. This hygrostat works autonomously, without the risk of reaching a hygrometry rate that is too low.
A
dehumidifier is a rather noisy device. Check the maximum noise level and determine if it is appropriate for the room you plan to install it in. For example, too much noise in a bedroom could prevent sleep. If possible, look for units with multiple fan speeds and a quiet mode.
The timer allows you to program the dehumidifier's operating hours. The overflow safety feature is also handy. This feature automatically shuts off the unit if the tank is full. And if you're planning a basement installation, check for an anti-freeze function.
Humidity is the number one problem in homes. According to an INSEE survey, 1 out of 5 households has to deal with persistent fog on the windows, walls that ooze, wallpaper that curls, a proliferation of cockroaches and mites, not to mention the smell of mold. Identifying the cause is the key to getting rid of it.
Leaks and water infiltration
It's easy to spot a burst pipe or a leaky washing machine hose. But it can take months to notice a shifting roof tile, a crack in the exterior plaster or a porous shower pan seal. Check the condition of the framing, walls and floors of wet rooms.
Water rising from the ground
Rising water from the ground is the most serious cause of moisture in a home. It permeates the foundations, forcing you to finance heavy work. Moisture is indicated by a clear demarcation of colors on the walls, the wet areas being darker. According to a study published in 2010, houses built before 1948 are 3 times more likely to be damp than those built after 1999.
Non-compliant mechanical ventilation
Living in a new house does not protect you from humidity. In fact, 1 out of 2 new homes has a non-compliant mechanical ventilation system. Poorly installed and insufficient flow rates are particularly pointed out. In addition, excessive caulking promotes condensation on plaster and interior plaster, knowing that a family of 4 people produces 6 kg of steam per day.
Putting a wainscot on a wall
If you have a leaky roof or water infiltration in the walls, don't install wainscot. Although affordable, this solution hides mold, but does not get rid of it. The air circulating behind the siding will pick up water vapour and cause mould to grow throughout your home.
Redoing the wallpaper
Another facade renovation, another solution doomed to failure. In particular, avoid waterproof coatings, a remedy that is worse than the disease. By preventing evaporation, these coatings trap moisture in the wall. Similarly, waterproofing an exterior wall that is subject to rising water vapour will only make the situation worse.
Use a dehumidifier
The dehumidifier will dry out walls, woodwork and frames. It is ideal in a poorly ventilated cellar or to dry out after a flood. By capturing the humidity in the ambient air, this device brings immediate comfort. However, electric dehumidifiers are preferable to chemical absorbers.
Call on a building professional
If you have a chronic moisture problem and the cause has been located, hire a building professional. By treating the problem at the source, he will remove the origin of the leak, seal the infiltrations... It is also necessary to call a professional in case of capillary rise. No dehumidifier can get rid of it.
Insulate cold surfaces and reduce steam
Steam condenses on cold surfaces. You can prevent the risk of mold by insulating these surfaces and replacing single-glazed windows with double glazing. You can also take these steps on a daily basis: take shorter, cooler showers, cover pots and pans, run the hood while cooking, or dry clothes on lines outside.
Airing the house
Airing the house for at least 10 minutes a day allows water vapour to be evacuated. Indeed, the air outside is often less humid than the air inside. Also check the condition and efficiency of your ventilation system. If possible, install a hygrogeable VMC, which adapts the air flow to the indoor humidity.
Heat less, but consistently
In winter, a temperature of 19°C is enough to make the living rooms pleasant. There is no need to overheat the house, even though cold air saturates more quickly than warm air. It is better to heat less, but in a constant way. But do not use unvented gas or oil heaters, as they produce large amounts of steam.
In addition to fighting the proliferation of mold, cockroaches and mites, this device keeps food (flour, cereals ...) longer in a humid environment. It also eliminates bad odors. Small dehumidifiers make it easier to dry towels in the bathroom. And in case of flooding, this device dries the house more quickly.
The humidity level in a given room is a measure of the quality of life. When it is too high, residents can expect to experience respiratory discomfort. In addition to this, there is also the appearance of mold on the walls, not to mention bad odors. The solution is to use a dehumidifier. It allows to decrease the humidity content in the air in order to make the place in question much more pleasant to live in. There are two main types of dehumidifiers on the market.
Also known as a desiccant dehumidifier, this type of unit is ideal for rooms with varying temperatures. Certainly, the more you comply with this condition, the more effective it is. The advantage of this type of dehumidifier is that it continuously maintains its power regardless of the excess humidity detected and the temperature of the room.
To extract the humidity, this device uses a slice gel that retains the water
. But before that, it attracts and absorbs the humid air via its fan. On the other hand, accompanying it with a drainage system would be useful. Finally, compared to other types, it turns out that its sound level is largely low.
We
recommend this type of dehumidifier for rooms where the temperature can exceed 18 ° C. In other words, it would be wise to invest in the purchase of this machine if you live in a hot place you if you absolutely must keep an even room temperature at all times. The best places for its use are therefore a warehouse, a laboratory or even a construction site. That said, to the detriment of its efficiency, the noise emanating from it is a disadvantage to be taken into account when using it.
This type of device works as follows: a fan sucks the humid air into the room and then cools it down by means of compression. Then the unit dries the air before blowing it back into the room. The collected water is discharged into a special tank.
The air dehumidifier allows to reduce and control the humidity level. It gets rid of moulds that not only destroy the house, but also harm the health of the occupants. Capable of purifying the air, this device has a reasonable consumption. On the other hand, it does not heat the air in winter and does not cool it in summer.
A multi-purpose device, the air conditioner can clean the air in the room and dehumidify. In addition, it cools in summer and serves as a backup heater in winter if it is a reversible air conditioner. On the other hand, it consumes a lot of energy and can cause illnesses if exposed for a long time. And it does not dehumidify as much as a real dehumidifier.
If you have problems with mold and odors, you need a dehumidifier, which can be used year-round and uses much less energy than an air conditioner. People who are sensitive to air quality should also opt for a dehumidifier.
A reversible air conditioner is useful to supplement an aging heater until it is replaced. Conversely, you need a dehumidifier if your heating system is efficient and you don't have cooling needs.
To live in a healthy place
Designed to eliminate humidity, the air dehumidifier helps you prevent the development of mold and mildew inside your home that can make breathing difficult. At the same time, you will get rid of unpleasant odors. In addition to moisture-free air throughout your home, you will enjoy a clean environment and perfectly breathable air. Doctors recommend it for elderly people and those who suffer from respiratory diseases.
To stay healthy
By removing mold, the air dehumidifier protects your skin and respiratory system. If you are sensitive to allergies and other irritations, this device will be very useful to you. With it, you will enjoy a better comfort.
To protect electronic devices
It is well known that humidity and electronic devices do not mix well. By using an air dehumidifier, you will extend the life of your electronic equipment. This is achieved by eliminating the humidity that is responsible for the rusting and corrosion of certain metals. Moreover, the dehumidifier is a compact and well-designed device that requires no special maintenance. You only need to clean and empty the water tray to optimize its performance.
To reduce the feeling of cold
Even if it is not its primary purpose, an air dehumidifier helps to warm the air in a home during the winter. In fact, the feeling of cold that you experience will be slightly reduced, because the device will make the air drier. This will make you more comfortable.
To allow clothes to dry
In winter, drying your clothes can become a problem, especially if you live in a colder area. The air dehumidifier will be a precious help if you have to dry your clothes inside the house. Indeed, by drying, your clothes will only increase the humidity level in the air. The unit will be able to extract this excess moisture.
In our opinion, the best brands of electric air dehumidifiers in 2022 are :
The Italian manufacturer is known for its coffee machines, air conditioners and heaters. De'Longhi is also one of the leading brands in dehumidification. Its name is synonymous with quality.
This brand is a reference for portable dehumidifiers and mini dehumidifiers. You'll be hard pressed to find a better one for less. For small areas, Pro Breeze is a must.
The German manufacturer offers everything. Its air treatment appliances are very popular, especially the dehumidifiers. Klarstein remains a safe bet, suitable for all budgets and all needs.
The brand specialises in air treatment and produces air conditioners, fans, air coolers, heaters and dehumidifiers. Suntec Wellness is known for the robustness of its appliances.
Everyone knows Rowenta for its vacuum cleaners, irons and hair dryers. But the German brand also excels in air treatment. The quality of its dehumidifiers proves it.
The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Empty the tank regularly.
Drain the water collected by the dehumidifier after each use or before moving it to another room. This will help the unit work more efficiently and longer.
Humidify the air appropriately.
As a
general rule, you should aim for a relative humidity between 30% and 50%. But be careful if you're using your machine to protect valuable items, such as guitars or vintage cars - you'll need to have the humidity level checked by a specialist.
Think about the appropriate location.
Keep
your dehumidifier away from walls, curtains and furniture, and keep all doors and windows closed when you use it. The more centrally the unit is placed in the room to be dehumidified, the better it will do its job.
Use at the right time.
Dehumidifiers are most effective when you have excess moisture in your home. So turn on your unit right after you take a shower. And if possible, don't dry your clothes inside.
Take control of the frost.
If
you're using a dehumidifier in a cool room-for example, in a basement-check that the dehumidifier has a frost control. This will prevent the dehumidifier from freezing if it gets too cold during use.
The best air dehumidifier depends on your needs and budget. Read our buying guide to find out which products are the best at the moment.
First, the dehumidifier prevents the proliferation of mold, cockroaches and dust mites. It also increases the shelf life of food in a humid environment. In addition, the appliance eliminates bad odours and can dry clothes. And in case of flooding, it dries the house more quickly.
First of all, consider the area to be dehumidified. The absorption capacity, automatic humidity adjustment, noise level and features such as programming are also important. Not forgetting the design.
The cheapest ones sell for about 40 euros. Construction site dehumidifiers can exceed 1,000 euros.
We highly recommend De'Longhi, Rowenta, Pro Breeze, Klarstein and Suntec Wellness.
