A review and comparison of the best bathroom dehumidifiers on the market

Energy star rated for efficiency

1. Honeywell TP30KWN

Honeywell is one of the biggest brands so it was natural to choose the Honeywell TP30WKN as one of the best dehumidifier models on the market!

If energy efficiency is important to you, you’ll be pleased to know that the Honeywell is energy star qualified which is great for you because you will reduce energy costs.

It has a washable air filter which prevents white dust from being dispersed, something that many other brands have issues with. It’s reusable too- simply hand wash it and then put it back inside the compact unit.

You will know when to clean it because there’s a clean alert on the LCD display on the control panel.

The water tank is detachable making it simple for you to empty it when it is full. It holds up to 30 pints per day, perfect for a 200 sq ft room.

It’s also a portable dehumidifier and can be easily moved from one room to the next.

There’s a sleep function so you can keep the dehumidifier in your bedroom and your sleep won’t be disturbed.

The Honeywell has a 24 hour on/off timer that cuts energy and cost and there’s an auto shutoff function in case of an electrical surge. This stops you worrying about switching it back on if there is an electrical surge- it will automatically happen.

Honeywell is a name you can trust and when choosing the best bathroom dehumidifiers, you won’t regret it!

Our runner-up dehumidifier pick

2. Inofia 30 pint

The Inofia is an energy efficient dehumidifier suitable for your bathroom.

It’s built-in humidistat lets you select your desired humidity percentage and keeps track of the humidity in the room and switches on an off depending on the desired humidity levels. Forget getting a separate digital hygrometer and you’ll cut down your bills because it only works when it’s necessary.

The auto shutoff functions switch the dehumidifier on and off according to the humidity levels you want in your bathroom. No more worrying about measuring the high humidity yourself and switching the unit on and off!

The 24 hour on/off timer is also handy and you won’t be running it unnecessarily. Cut electricity usage by adjusting the fan speed too.

Empty the 0.5 gallon tank when it is full either manually yourself or attaching the 6.56 foot hose for continuous drainage using gravity.

If you live somewhere cold, your bathroom can get cold while still being damp and luckily the Inofa has an auto defrost function which prevents it freezing up like other appliances would.

The Inofia’s recessed handle and compact size makes it simple to move in and out of your bathroom, especially if you plan to have it in other rooms in your home. It also makes it easier to empty manually.


Energy efficient saving you money on energy bills

Auto stop and auto restart: forget about stopping and starting it yourself

Auto defrost so it can be safely used in winter

Outage restart that gets the dehumidifier working again after a power outage.

3. Airplus dehumidifier

The Airplus 30 pint model is great for bathroom use.

Its water tank holds 1.5 liters of water. Once it’s full, you can either manually empty the water or you can set up the continuous drainage option istead.

We love the Airplus because of the 4 different modes available: standard, drying, sleep (reduces noise if using at night) and raining mode (more heavy duty for wet, damp conditions). It’s a great dehumidifier to use in your bathroom or when air drying your garments.

The Airplus’ washable reusable filter prevents white dust in the room while the unit is operating. You can just wash and reuse without worrying about replacements.

It’s easy to move the Airplus around because it has universal wheels making it a portable dehumidifier.

It comes with a 2 year warranty for peace of mind!


Can be used in your laundry to help speed up your clothes drying

It has four functions depending on your requirements

Best budget option

The Pro Breeze Mini Dehumidifier is a popular option for those wanting small bathroom dehumidifiers that are an efficient and compact unit for a small room or space.

The Pro Breeze uses ultra quiet Peltier technology, meaning that it can extract more moisture from the air than many dehumidifiers can while still using the same amount of electricity. The technology improves its efficiency.

The water tank can store up to 16 ounces of water. The unit extracts up to 8 ounces per day.

Operation is 23 watts.


Very efficient and compact unit

The Ivation IVADM35 is a small dehumidifier. It’s an excellent choice for bathrooms and other small rooms, and especially recommended for areas with excess humidity.

It’s a great mini dehumidifier especially if you’re shopping for small bathroom dehumidifiers.

The unit uses both ultra quiet 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 from the air using the same consumption as a unit without the ERS technologies.

So, how is the moisture removal? It has an extraction capacity of up to 12 ounces of moisture per day, and the water tank has a capacity of 22 ounces. This is greater than most others currently on the market.

Once the water tank is full, the LED indicator light changes from blue to yellow that tells you its time to empty the tank. When the water tank is full, the dehumidifier shuts off thanks to the auto shutoff feature.

A quick summary of what to look for when choosing the right model

  • Will the dehumidifier be in the bathroom only or other room too? Make sure the size you choose suits the room. Castor wheels help with portability.
  • How often do you want to empty the water tank? Look at the amount of water that can be emptied in one day and the water tank capacity to work out how often to empty it. Of course, also consider how many hours per day it will be operating.
  • Choose the right size for your bathroom. A small bathroom or ensuite may only require a mini dehumidifer.

Electric dehumidifiers can be used in many rooms and areas around your home including your bathroom, basement or a crawl space where excess humidity level is an issue.

If your bathroom doesn’t have a bathroom extractor fan, then a small dehumidifier for bathrooms is a perfect solution for moisture removal. There are some that can be wall mounted and ceiling mounted.

Which dehumidifier technology is best?

Many dehumidifiers are either compressor-based or Peltier technology. Peltier technology is better because it’s more energy efficient, there is less noise and the unit is lightweight.

It’s important to know that dehumidifiers work by helping with moisture removal, but they cannot cool down warm air like an air conditioner can.

When choosing the best dehumidifier, there are some differences you will need to be aware of between each of the units.

Differences to look out for are the type of technology, the moisture extraction ability and the water tank capacity. The more the tank capacity, the less often you will need to dump the water. This is important for those who live in very humid climates.

How to compare each model?

Each dehumidifier has a water tank capacity, which is how much excess moisture the unit can carry. Each model also has a maximum capacity that can be withdrawn from the air per day. The key is to find out how often you would empty the water tank.

Looking at the mini bathroom dehumidifiers, or even just a small dehumidifier, if they were running all day every day, you would empty the tank every 1.5 days. However the reality is that you wouldn’t run it all day in a bathroom. But if this is something you find important, then choose the Ivation as it withdraws more excess moisture per day than the other models reviewed and has a larger water tank capacity.

We recommend the Honeywell or the Inofia 30 pint. As they are both on castor wheels, you can move it from a bathroom to another room.

Can I use it in the bathroom?

Yes, by using it in your bathroom you are helping to prevent excess moisture and prevent mold growing. This is because bathroom dehumidifiers remove the moisture in the bathroom. Moisture is what is needed for mold to grow.

Now that you know that they do work in bathrooms, it’s time to choose one to buy. Read our reviews to find the best brand and model dehumidifier for your bathroom.

What size do I need?

Your best option is a 30 pint model which is perfect for a bathroom but can also be in other rooms in your home. You can read more about dehumidifier standards as set out by the U.S. Department of Energy.

Small bathroom dehumidifiers that extract up to 8 ounces of moisture per day are suitable for your bathroom. These dehumidifiers have water tanks that typically contain up to 16 ounces of water.

A common error many people make is buying the wrong type of dehumidifier, such as a small dehumidifier or one not strong enough for the room they need to dehumidify.

The best dehumidifier may not be suitable for other rooms. And a large dehumidifier better suited to a big room may be too noisy and big to be placed in a bathroom. It’s important to consider the room size when choosing a dehumidifier.

Our favorite bathroom dehumidifiers we have reviewed in this post are all suitable sizes for a bathroom. They are smaller than your average dehumidifier unit.

Different types of technology

Small bathroom dehumidifiers 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 energy 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 lots 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 tropical climate, then it’s recommended you find a bathroom dehumidifier that has a bigger tank capacity.

Common complaints

The most common complaint that people make about bathroom 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 room is not very wet to begin with. Humidity levels in a room and the relative humidity level are important to measure before deciding if you need a humidifier or a dehumidifier.

Another problem could be that the wrong type of dehumidifier has been purchased for the room or space. As mentioned earlier, a small dehumidifier won’t be suitable for a big room.

Are dehumidifiers noisy?

Another typical complaint about bathroom 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.

One final word…

These are our top picks of the best dehumidifiers for bathrooms, and our reviews of each dehumidifier. Your choice will largely depend on your budget, your desired 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 (much like air purifiers can) and reduce mold and mildew, bacteria and germs that breed in humid rooms.

U.S. Department of Energy (DOE) defines performance ratings for dehumidifiers and test methods for determining performance.
