Best dehumidifier for bathroom- Reviews 2018


Dehumidifiers can be used in many rooms and areas around your home. They are used in a bathroom, basement or a crawl space where humidity is an issue. If your bathroom doesn’t have a fan, then a small dehumidifier for bathroom use is a perfect way to remove moisture.

A small bathroom dehumidifier is either compressor-based or uses Peltier technology. Peltier technology is better because it’s more energy efficient, there is less noise and the dehumidifier is lightweight.

It’s important to know that dehumidifiers remove the moisture in the air, but they cannot cool down the air like an air conditioner can.

The Pictek mini air dehumidifier extracts about 8 ounces of water per day and its water tank has a capacity of around 17 ounces of water. Once the tank has reached its capacity, it shuts off automatically. An LED indicator light lets you know when it is time to empty the water tank. The tray at the bottom slides out so that you can empty the water tank.

It has whisper quiet operation, at under 35 DB.

As there is no compressor, the unit uses a semiconductor, making it eco-friendly and low on energy consumption.

There is a 12-month warranty and a 30-day money back guarantee.

The Ivation ERSDM18 dehumidifier is an excellent choice for bathrooms and other small rooms, and especially recommended for use in areas with high levels of humidity.

The unit uses both Peltier and ERS technologies. ERS technologies help to balance the temperature of the Peltier element, which is typically hot on one end and cold on the other. By balancing the temperature, the unit is able to extract more moisture using the same power consumption as a unit without the ERS technologies.

It can extract up to 12 ounces of moisture per day, and the water tank has a capacity of 22 ounces. This is greater than most other dehumidifiers currently on the market.

Once the water tank is full, the LED indicator light changes from blue to yellow which indicates it needs to be emptied. When the water tank is full, the unit shuts off automatically.

How to choose the best dehumidifier for bathrooms

Not all dehumidifiers are the same. When choosing the best dehumidifier for bathroom use, there are some differences you will need to be aware of between each of the units.

Differences to look out for are the technologies used, the moisture extraction ability and the water tank capacity. The larger the tank capacity, the less often you will need to empty the water. This is particularly important for those who live in very humid climates.

Size of the area

The first thing to consider is the room or space that you want to dehumidify. A common error many people make is buying the wrong type of dehumidifier, one that is too small or not powerful enough for the room they need to dehumidify. The best dehumidifier for bathrooms won’t be suitable for a large basement. And a large dehumidifier better suited to a basement may be too noisy and large to be placed in a bathroom.

Type of bathroom dehumidifier

Small dehumidifiers for bathrooms typically use a compressor or Peltier technology. Peltier technology is used to control the temperature- the Peltier heat pump cools the surface and condenses the water vapor from the humid air. Peltier technology means no moving parts are required, and operation is much quieter when compared with a dehumidifier that uses a compressor. It also makes the unit lightweight.

Efficiency levels

When deciding on a dehumidifier for your bathroom, it’s a good idea to know how much moisture the unit can extract before the water tank needs to be emptied. It’s also important to know how much power the unit consumes. By knowing these two pieces of information, you can determine whether the dehumidifier is efficient. If you can find a unit that extracts a larger amount of moisture but at the same power consumption level of a dehumidifier with a lower extraction, then you know you have found an efficient dehumidifier. This is important for the environment, and for your wallet!

Water tank capacity

If your bathroom dehumidifier has a large water tank, then it means you will not have to empty the tank as often as a bathroom dehumidifier with a smaller tank. This is because the water tank can hold more moisture. If you live in a humid climate, then it’s recommended you find a bathroom dehumidifier that has a larger tank capacity.

Common complaints about dehumidifiers

The most common complaint that people make about dehumidifiers is that they are not working properly, simply because there isn’t much water in the water tank. Sometimes there may be a fault with the unit itself, but usually the problem is that the room is not very humid to begin with. Another problem could be that the wrong type of dehumidifier has been purchased for that particular room or space. As mentioned earlier, a small dehumidifier for bathroom use won’t be suitable for a large basement.

Another typical complaint about dehumidifiers is the noise level. Just like any other appliance, a dehumidifier will make noise. Whether the noise is loud or not is subjective, but it is often described as sounding similar to an air conditioner. Keep this in mind when purchasing a dehumidifier- expect some level of noise.


These are our top 5 picks of the best dehumidifier for bathrooms, and our reviews of each dehumidifier. Your choice will largely depend on your budget, your bathroom’s humidity level and your personal preference.

Once you start using your new dehumidifier, you will notice a difference to the level of humidity in the bathroom. It will improve the air quality and reduce mold, bacteria and germs that breed in humid rooms.

Consider the tips and suggestions about what to look for when buying the best dehumidifier for bathrooms, and the buying process will be much easier for you.
