What is The Best Small Room Dehumidifier
Hysure 2000 ml: the best cheap
[amazon box=”B07F29TM68″]
This Hysure dehumidifier is a compact product, easy to place in a room and then move according to your needs. It measures 37 cm high, 23 cm wide and 15 cm deep. It weighs 2.5 kg, and it has a large carrying handle. The power cable measures 1.5 m. It is designed to be effective in rooms up to 20 m².
Getting started is very easy since there is only one button on the top of the dehumidifier. All you have to do is plug it in and then press it (be careful in the event of a power cut, it does not turn on again). For some people, this is a defect because it means that there is only one air handling power. Impossible to go more or less loud, and also impossible to limit the noise at night. Because if it is relatively discreet, it still has a sound level of 42 dB, which can disturb sleep. It is best to turn it on when you go to bed and then turn it off until you wake up the next morning.
The device has the capacity to treat 750 ml of water per day. It has a 2-litre tank which is removable for quick emptying. A safety system stops automatically as soon as the tank is full. This allows you not to worry if you forget to do it. However, it is better to remember to empty it to keep the room as dry as possible.
Pros
- Easily portable
- Large 2 l tank
- One button only
- Up to 750 ml per day
- Quite quiet noise
Cons
- For small areas only
- No power controller
Pro Breeze Electric Mini Dehumidifier
[amazon box=”B01HXVUT7C”]
Pro Breeze has declined the same type of dehumidifier in several formats, mainly named according to the size of the tank. Here it is a model that can contain up to 1.5 l of water at one time. When the tank is full, a float system directly interrupts the device and a light signal lights up red.
The drain is very easy because the tank works like a drawer. It is just as easy to put it back in its place correctly. In the same idea, the dehumidifier is relatively light, and it has a large handle (on the back and therefore invisible at first glance). It is, therefore, possible to have only one device and to move it as needed.
The power of the device (72 watts) allows it to evacuate 500 ml per day. However, for optimal operation, it must be positioned in a room in a house with a maximum surface area of 15 m². It is also preferable to position it in a relatively heated place, that is to say, between 18 and 30 °, according to the opinions posted online.
It is, therefore, not necessarily a suitable device against humidity in a cellar, but it can be placed in a bathroom, as well as in a kitchen or a bedroom. It is even possible to plug it into a programmable outlet (so that it only works when you leave the shower every day, for example).
Moisture is absorbed through a thermoelectric cooling system. This makes it a relatively discreet product. However, it still emits an audible purring which could annoy those most sensitive to noise, especially at night.
Pros
- Large tank
- Carrying handle
- Discreet
- Power of 500 ml/day
- Easy emptying
Cons
- For rooms up to 15 m²
- Need a temperature> 18 °

[amazon box=”B07WV24SNS”]
With dimensions equal to 16 x 11 x 27 cm, this device is small. It does not occupy much space either during use or when storing. However, its performance is not judged by its size. In fact, it can eliminate 300 ml of water every 24 hours in a room with a humidity of 80% and a temperature equivalent to 30 ° C. It ensures that you can protect yourself from the negative effects of excess humidity in the place where you live.
Its reservoir has a capacity of 670 ml, which is large enough to limit the frequency of its emptying. The use of this material is secure. Indeed, it is able to switch off automatically by exceeding by 100 ml its maximum allowable capacity, which is equal to 500 ml. So you don’t have to constantly monitor its operation.
To avoid any trial and error during use, a yellow light comes on when said maximum capacity is reached before automatic shutdown. The noise level emitted by this dehumidifier is limited to only 33 dB. It is not likely to disturb you in your sleep if you use it at night.
Using a material that dehumidifies the air allows you to live in comfort if you choose a model that suits your needs. Let us see the case of this product.

How to choose your Best Small Room Dehumidifier?
Choosing a particular dehumidifier depends on the room where you are going to use it, including volume, room temperature and humidity. We do not buy the same device to reduce the humidity in a bathroom and regulate the humidity in a cellar. Here are the selection criteria to remember.
Criterion 1: The type of dehumidifier
The condensing dehumidifier, also known as a compressor dehumidifier, is the most common choice. It passes moist air through a filter and then condenses it. The water resulting from this condensation passes into the tank, and the dry air is diffused in the house. This system is suitable 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 drip tray. 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 sucked-in humid air passes near the hot plate, then the cold plate. Thus, the collected vapour becomes water. Ecological and inexpensive, it is suitable for small surfaces.
Criterion 2: The extraction capacity and the size of the reservoir
Expressed in litres per day, the extraction capacity is defined as the quantity of water absorbed by the dehumidifier in 24 hours. This indicator is often combined with the airflow, expressed in m³ / h, to assess the volume of the room in which the dehumidifier can be used.
The size of an air dehumidifier tank will depend on its extraction capacity. Some devices may have a large extraction capacity but a small tank. In this specific case, an evacuation pipe allows continuous drainage. Or a lift pump for high evacuation.
Criterion 3: Control of the humidity level
Most dehumidifiers are equipped with an automatic hygrostat. It is a group of sensors that monitor the humidity level in the ambient air and adjust it between 45 and 60%, the ideal level in a home. This hygrostat works autonomously without risking reaching a too-low humidity rate.
Criterion 4: The sound level
A dehumidifier is a rather noisy device. Check the maximum sound level and determine if it is suitable for the room where you plan to install it. For example, too loud a noise in a bedroom could prevent sleep. If possible, choose devices that offer multiple fan speeds and a silent mode.
Criterion 5: Features
The timer allows you to program the hours of operation of the dehumidifier. Overfill protection is also practical. This function automatically stops the appliance in the event of a full tank. And if you plan to install it in the cellar, check for the presence of an antifreeze function.
A dehumidifier or air conditioner?
The dehumidifier
The air dehumidifier helps to reduce and control the humidity level. It gets rid of mould, which not only destroys the house but also damages 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 in summer.
The air conditioner
A versatile device, the air conditioner can purify the ambient air and dehumidify. In addition, it cools in summer and serves as additional heating in winter if it is a reversible air conditioner. On the other hand, it is very energy intensive and can cause illness in case of prolonged exposure. And it doesn’t dehumidify as much as a real dehumidifier.
Conclusion
If you have mould and bad odour problems, you need a dehumidifier, which can be used all year round and uses much less energy than an air conditioner. People sensitive to air quality should also opt for a dehumidifier.
A reversible air conditioner is useful to supplement an ageing heater while waiting to be replaced. Conversely, you need a dehumidifier if your heating is efficient and you have no cooling needs.
How to remove humidity from the house?
The sneaky phenomenon, humidity is the number one problem with housing. According to an INSEE survey, 1 in 5 households faces persistent mist on the windows, oozing walls, curling wallpaper, a proliferation of cockroaches and mites, not to mention the musty smell. Identifying the cause helps to get rid of it.
Identify sources of moisture
Leaks and water infiltration
It’s easy to spot a broken pipe or a leak on a washing machine hose. But it can take months before you notice a shift in tile on the roof, a crack in the exterior plaster or the porous seal of a shower pan. Check the condition of the frame, walls and floors in damp rooms.
Upwelling from the ground
Water rising from the ground is the most serious cause of dampness in a home. It permeates the foundations, forcing you to finance heavy work. The humidity is materialized by a clear demarcation of colours on the walls, the wet parts 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.
Mechanical ventilation is not compliant
Living in a new house does not protect you from humidity. Moreover, 1 out of 2 new housing has a non-compliant CMV (controlled mechanical ventilation). Poor installation and insufficient flow rates are particularly singled 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.
What you should avoid
Install a panelling on a wall
If you have a pierced roof or water infiltration in the walls, do not install panelling. Despite its affordable cost, this solution hides mould but does not get rid of it in any way. The air circulating behind the plating will take on water vapour and cause mould to grow throughout the house.
Redo the wallpaper
Another facelift, another solution doomed to failure. In particular, avoid waterproof coverings, a cure that is worse than the ailment. By preventing evaporation, these coatings trap moisture in the wall. Likewise, a waterproof coating on an exterior wall subject to capillary rise will only worsen the situation.
What you should do Best is a Small Room Dehumidifier
Using a dehumidifier
The dehumidifier will dry out walls, woodwork and frames. It is ideal for a poorly ventilated cellar or for drying out after a flood. By capturing humidity in the ambient air, this device provides immediate comfort. However, prefer electric dehumidifiers 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, it will remove the origin of the leak, plug the infiltrations… It is also necessary to call a professional in the event of capillary rise. No dehumidifier can get rid of it.
Insulate cold surfaces and reduce steam
The steam condenses on cold surfaces. You can prevent the risk of mould by insulating these walls and replacing single-glazed windows with double-glazed windows. You can also adopt these daily gestures: take cooler and faster showers, cover pots, run the hood while cooking or dry clothes on ropes outside.
Air out the house
Airing the house for at least 10 min/day allows water vapour to escape. Indeed, the outside air is often less humid than the inside air. Also, check the condition and efficiency of your VMC. If possible, install a humidistable VMC, which adapts the airflow to the indoor humidity.
Heat loss, but steadily
In winter, a temperature of 19 ° C is enough to make the living rooms pleasant. Overheating the house is unnecessary, even if cold air saturates faster than hot air. Prefer to eat less, but constantly. But do not use ventless gas or petroleum heaters, as they produce large amounts of steam.

Tips
Empty the tank regularly
Empty the water collected by the dehumidifier after each use or before moving it to another room. This will help the device to work more efficiently and for longer.
Humidify the air appropriately
As a general rule of thumb, you should aim for relative humidity between 30% and 50%. But be careful if you use your machine to protect valuables, like guitars or vintage cars – you will 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 in use. The more the appliance is placed in the centre of the room to be dehumidified, the better it will fulfil its role.
Use at the right time
Dehumidifiers are most effective when you have excess humidity in your home. So, turn on your device right after taking a shower. And if possible, don’t dry your clothes indoors.
Take control of the frost
If you are using a dehumidifier in a cool room – for example, in a basement – check that the dehumidifier has frost control. This will prevent the dehumidifier from freezing if it is too cold during use.
