5 Best Small Dehumidifier for Bathroom (Portable & Quiet)
A Bathroom with humidity levels above 60% can become the hotspot for dust mites, mold, and mildew. According to Environment Protection Agency, relative humidity levels between 30% and 50% are appropriate for a room. However, this is difficult to achieve in a bathroom.
In your entire home, a bathroom is a place where you’ll find high levels of humidity. It is due to the amount of steam that a hot shower or bath produces.
What’s the solution?
A dehumidifier can help significantly improve the air quality by removing moisture from the air, preventing the growth of mold and mildew. Also, if your bathroom has a poor ventilation system or no window to release the air, placing a dehumidifier will help.
Smaller Dehumidifiers are best for small spaces such as a bathroom, laundry room, or closet.
As said, bathrooms are generally small in comparison to living rooms so a low capacity model can easily manage the humidity levels. Besides, due to its portable nature, you can move it to another part of the house with ease. Sounds like a win-win device, Right?
When shopping for a small dehumidifier for your bathroom, you must consider some of the important factors before finalizing such as capacity, portability, noise level, purification, etc.
Below is a buying guide for picking the right dehumidifier for your bathroom.

Best Small Dehumidifier for Bathroom Buying Guide
Water Tank vs Absorbing Capacity
The water tank inside a dehumidifier holds water by extracting it from the air. Every dehumidifier comes with a water tank that can hold a certain volume of water. For example, A dehumidifier of 16 Oz water tank can hold 500 ml of water.
On the other hand, absorbing capacity is the rate at which a dehumidifier can remove water particles from the air within 24 hours.
A rule of thumb is that a larger room space to dehumidify will require a larger absorbing capacity. Also remember, the more the water tank capacity, the more it will cost.
Bathrooms are generally small spaces in our home. A small dehumidifier with an absorbing capacity of 300 to 600 milliliters of water from the air (in 24 hours) is a suitable choice.
However, if you are dealing with larger space, go for high-capacity dehumidifiers. A High moisture absorbing capacity dehumidifier manages to handle an excessive amount of humidity in large spaces quickly.
Portability
You might not want your dehumidifier to be ideal in the bathroom only. Portable dehumidifiers come in handy when moving it to another part of the house.
Most cord-based dehumidifiers can be shifted from one place to another as it requires an outlet to be plugged in. Also, some models come with wheels and a handle to move around.
Another type of dehumidifier you might find is mini-dehumidifier. This cordless model is way smaller (size of a hand) and uses silica gel to trap water particles from the air. It is portable but not recommended as it won’t be effective in dehumidifying.
Noise Level
Dehumidifiers can be noisy sometimes. The main source of noise is its compressor, fan, and airflow (swirling sound). When picking a dehumidifier for your bathroom check whether it falls under recommended noise levels.
In general, a noise level between 53 dB and 57 dB is considered quiet (sounds like moderate rainfall). And below 53 dB is considered super quiet (sound of a refrigerator).
Here is a list of different noise levels of dehumidifiers to determine how noisy it can be:
- Loud dehumidifiers: Over 65 dB.
- Noisy dehumidifiers: Between 60 dB and 65 dB.
- Neutral dehumidifiers: Between 57 dB and 60 dB.
- Quiet dehumidifiers: Between 53 dB and 57 dB.
- Super quiet dehumidifiers: Below 53 dB.
Auto Shut Off & Defrost
You cannot always sit in the bathroom to check when the water tank gets full and needs to be emptied. Auto Shut off feature allows the dehumidifier to automatically turn itself off when the tank is about to overflow.
Besides, there is another feature called Auto-defrost. It ensures that your dehumidifier will work in low temperatures such as in winter or rainfall.
Drainage System
Mainly dehumidifiers have two types of drainage systems; sliding tray and sink/floor draining.
Sliding trays or tanks are common in most dehumidifiers; you have to slide the tray and empty the water collected in it. On the other hand, some use a drainage hose attached to the sink or drain that carries water out of the machine.
Built-in Humidistat Tool
Some dehumidifier models come equipped with a humidity measurement tool called a humidistat. It shows the moisture levels in the room and ensures whether an appropriate RH level is maintained inside.

FAQs: Small Dehumidifier for Bathroom
Do Dehumidifiers Work in Bathrooms?
Since bathrooms are the hotspot for moisture, it is likely to cause humidity-related issues such as the growth of dust mites, mold, and mildew. Placing a dehumidifier will work effectively to improve air quality by removing moisture.
How Does A Dehumidifier Work?
A fan inside the dehumidifier pulls the moist air over two sets of coils; cool and warm. The cool coil causes the moisture in the humid air to condense into the water which drips into a bin, then the air passes over the warm coil and flows back into the room. When the bin is full, the fan and compressor turn off. Once the bin is empty, the process repeats.
Where Should A Dehumidifier be Placed In a Bathroom?
Cord-based dehumidifiers require an outlet to be plugged in. Therefore, you’ll be placing your dehumidifier near the electric outlet of the bathroom. If the device has a good wire length, then you can move a few distances away from the outlet.
