Buying Guide to Choose a Small Dehumidifier for Bathroom
Buying the dehumidifier that best suits your needs is a task that requires some time. Unfortunately, the wide catalog of models offered by multiple brands on the market means that the purchase process wouldn’t be as fast as we’d like. So, here are a few factors to consider:
Type of Dehumidifier
Before picking a dehumidifier for your bathroom, you should consider the type you need. Let’s have a look at the two types of dehumidifiers.
These dehumidifiers absorb the air in your room with the help of a fan and then channel it through a cooling system. Thanks to this cooling process, the water in the absorbed air condenses, precipitating drop by drop inside the filling tank. The processed air is preheated back to room temperature and expelled back into your room.
These dehumidifiers are the most common and are most effective when the temperature and humidity are high (above 40% relative humidity).
These dehumidifiers base their operation on desiccant materials, the most common being silica gel. The sucked air passes through the desiccant material, which condenses the humidity inside the filling tank through a chemical reaction. Then, an additional airflow regenerates the material to be reused as many times as needed.
Moreover, desiccants perform better than refrigerant dehumidifiers in low temperatures. The reason is that refrigerants tend to get frozen or remain in defrost mode for longer periods and tend not to remove moisture from the air in that state. On the other hand, desiccant dehumidifiers continue removing moisture from the air even at 0°F.
So, whether you should buy a desiccant or refrigerant dehumidifier depends on the prevalent temperature in your geographical region.
Refrigerant-type dehumidifiers consume an average of 250 W, while the desiccant type consumes an average of 500 W of power. We could say the average consumption of a refrigerant dehumidifier is comparable to a refrigerator and a desiccant to that of a washing machine.
However, we have to clarify that dehumidifiers never work at their maximum power and don’t run continuously. This is because most dehumidifiers on the market have humidistats and timers that control their automatic switching on and off, depending on the selected settings.
Noise is a subjective parameter. Therefore, different people have different levels of noise tolerance. However, most dehumidifiers on the market operate between 30 and 50 dB.
For use in a bathroom at night, a device with a noise level of up to 45 dB is recommended. You can use air purifiers with up to 50 dB noise levels in other bigger environments.
Water Removal Capacity
This refers to the maximum amount of water that can be removed in 24 hours in an environment with 80% humidity and a temperature of 30 degrees.
The most common capacities are 12, 16, 20, or 35 liters. But that doesn’t mean your dehumidifier is going to remove this volume of water from your house every day. The total volume of water removed will depend on the relative humidity, the insulation of the environment (doors and windows must be well-closed), and the movement of people, among other factors.
So before choosing your dehumidifier, you need to know the size of the area you want to dehumidify. In this way, you can choose a device with compatible extraction capacity. Otherwise, you may get a device with an inadequate capacity.
Water Tank Capacity
You need to consider the size of the dehumidifier’s water tank. For example, for a bathroom of 430 square feet, we recommend dehumidifiers with a capacity of 600 to 1000 milliliters since they’ll have a good storage capacity.
In this way, you’ll need to empty the water tank fewer times. Also, we recommend dehumidifiers with 1000 milliliters and above for larger rooms and environments.
It’s essential to note that the greater the extraction capacity, the larger your tank will be. This means you’ll need to remove the water compartment fewer times.
Functions and Resources
In general, dehumidifiers have a function in which you can use the humidistat to select the desired humidity. With this function, the appliance turns on and off automatically to keep the humidity at the desired level.
Also, humidifiers have a continuous mode of operation, which keeps the device on until the tank is filled. You can use this mode to dry clothes indoors.
Furthermore, most humidifiers have a silent mode and promise a lower noise operation. However, there isn’t always such a difference. From our own experience, we can say that, even with this function activated, the noise of the compressor is the same. The only difference is a reduction in air circulation speed, which may reduce the total noise a little, but without great differences.
In addition, some mini dehumidifiers may also have a timer, which will allow you to leave them on for a defined number of hours, which is also a way to save energy.
Frequently Asked Questions
Why Is a Bathroom Dehumidifier Necessary?
A bathroom dehumidifier is necessary because of the mold, mites, and evident condensation that may occur after some pleasant showers (especially if there’s no ventilation). Sometimes, these may cause the relative humidity to go as high as 100%.
In addition, you need a humidifier in your bathroom because of the visible fogging of the mirrors, windows, and the environment in general. Also, the mold on the walls, in the joints of the tiles, and the persistent bad smell of the towels and other clothes that you store in the bathroom are some of the main reasons why it’s necessary to buy dehumidifiers for the bathroom.
How Does the Bathroom Dehumidifier Remove Excess Moisture?
Dehumidifiers have a mechanism of action that requires an extractor, a cold coil, and a tank. The extractor absorbs the air, the cold coil condenses the moisture in the air, and the tank is where water is conserved. In addition, the extractor returns semi-dry air to the space. Also, most dehumidifiers have a second coil that slightly heats the air so that it’s not too cold for you.
Do Bathroom Dehumidifiers Have to Run All the Time?
If the place is a very hot area with high humidity in the air, it’s common and recommended that the equipment is always on. However, dehumidifiers have a humidistat, a small device that measures the percentage of humidity in the air. So, when the required level of humidity is reached, the device turns off, and if it exceeds it, the device turns on automatically.
Does the Dehumidifier Have to Be Installed in a Specific Place?
For the best results, it’d be best if the dehumidifier is located in the part or area of the room where the most moisture accumulates. However, we recommend installing your dehumidifier at the top center of the bathroom.
Are Mini Dehumidifiers Any Good?
Mini dehumidifiers are a great and affordable solution for those corners of the home, such as a bathroom, closet, cabinets, basement, laundry room, or small rooms. This is because they’re compact and can fit anywhere.
All these small dehumidifiers for bathrooms have a lot of interesting features that make them worth the buy. Whichever one you pick will be a good purchase because they all keep the air in your bathroom fresh and healthy. However, let’s recap our top three picks.
