A good bathroom dehumidifier can be the difference between a musty smelling bathroom and one that smells like a spa. Okay, you may need to do a little bit more work to get it smelling fresh but one of the main problems that a lot of readers face is keeping their bathroom dry. While excess moisture can cause serious problems such as caulk with mold and mildew or a sweaty toilet tank that does water damage to the bathroom floor, even just some extra dampness can cause towels to get stinky and leave your bathroom smelling anything but fresh.
Growing up in Minnesota with very humid summers and dry winters we had to alternate between dehumidifiers in the summer and humidifiers in the winter to battle dry central heat during a very cold winter. I was always amazed as a kid to see my dad pouring out gallons of water from the dehumidifiers. Keeping the basement dry was a constant battle and even more important since we had a bathroom in the basement and the nasty 70’s craze of carpeted bathroom floors!
Luckily now, there are really compact units that are also much more efficient than their predecessors. You can now get a quality bathroom dehumidifier for a decent price that can make a very noticeable difference.
At the end of the article, you’ll find a more in-depth look into the different factors that you need to consider before buying one, what size you need, what capacity you must get, and more.

Complete Guide: Dehumidifiers
A dehumidifier reduces and controls the amount of humidity in the air in a given space. This electrical appliance is beneficial for health and comfort. It is often used to prevent mold and mildew growth, as well as to get rid of any musty odors in the air by extracting excess moisture in the area.
It is commonly used in residential spaces, particularly in bathrooms, bedrooms, basements, laundry rooms, and even kitchens.
It can also be used in other places, even those in industrial and commercial settings. Larger models are used in commercial establishments, such as swimming pools and indoor ice rinks. It’s also common to see these in storage warehouses and manufacturing plants.
Benefits of Using a Dehumidifier
We know what it does and that it’s essential for any home. But how exactly does it benefit us?
Prevents Allergens, Mold, and Mildew
By reducing the amount of humidity present, dehumidifiers make your home less prone to allergens such as pollen and dust mites. It also fights the growth of mold and mildew, which thrive in moist environments.
Another annoying thing that goes with mold and mildew are unpleasant odors. By reducing the humidity, you also solve this problem. Say goodbye to pesky, musty, and rotting odors at home.
The great thing about them is how they keep working – quietly – in the background, as you go about your daily life. Most of the time, you won’t even notice it’s there. As a result, you prevent the possibility of mold and mildew growing on furniture, linen, clothing, and other fixtures.
Promotes Healthier Respiratory Function
Perhaps the most crucial function of the dehumidifier is this one. They minimize irritation to your respiratory system and skin. This lets you breathe easier, getting rid of sneezing fits. You’ll also feel a general improvement in the comfort level in the room.
Improves Day to Day Life
By reducing the humidity, you can dry your clothes much more efficiently. If you use the machine in the pantry or kitchen, you can keep staples like cereal and bread fresh for longer. When used in living areas, offices, and bedrooms, you can prevent corrosion and rust from taking over your electronics and tools.
You’ll also experience less rust at home, which reduces the need to clean as well.
Lowers Energy Costs
Finally, dehumidifiers can also let you enjoy significant savings on your energy spending. This is because it allows your air conditioners to run more efficiently. A room that has less humid air lets the AC unit to cool easier. The lack of moisture means that your AC doesn’t have to work as hard. This not just saves on utility bills but also protects the life and longevity of your AC unit.
Factors to Consider When Choosing a Dehumidifier
All of the dehumidifiers we laid out above are worthy investments. So how do you know which one is right for you? Keep reading to learn more.
Is Humidity the Problem?
The first step is to identify the scope of your problem. Is the entire house humid, or just one room or area? The scope will help determine which humidifier you need.
There are dehumidifiers designed for the entire house and are tied into your home’s HVAC system. These include a drainpipe that directly empties into a sump pump, slop sink, or outside the house. These are heavy-duty and are thus more expensive. You’ll also likely need professionals to install it for you.
Meanwhile, portable dehumidifiers are cheaper and more user-friendly in terms of control and installation. You just plug them into the wall and run using their built-in interfaces.
Some of these also come with hoses that drain collected water outside or through a drain automatically, like many of our featured products earlier. Some only come with a tank or bucket, which you need to empty regularly manually.
Choose Energy-Efficient Dehumidifiers
Next, decide what kind of investment you want to make. Dehumidifiers that are certified with an Energy Star means that they utilize as much as 15% less energy than those which don’t have the certification. In addition to savings on your bills, these are also supremely better for the planet – they prevent around 2800 lbs of greenhouse gas emissions!
You can choose Energy-Star rated units, which we highly recommend, although they might cost a bit more at first. The savings, in the long run, will make up for this, though!
Which Size of Dehumidifiers is Right for You?
You’ll need to know the size of the bathroom or home. Before choosing a dehumidifier, you have to consider how big of a space you need to dehumidify – otherwise, you might end up buying the wrong machine for the job. If you don’t know your room or home’s measurements, take a measuring tape and get the width and length of the floor. Multiply the two values, and this is your room’s measurement (in either square feet or square meters).
Most buildings have an ideal RHL (relative humidity level) of 30-50% to keep the room comfortable and free from mold and bacterial growth. The majority of dehumidifiers in the market have a humidistat to control the settings for the best level of humidity for your home.
Dehumidifiers for the Whole House
For spaces over 2500 square feet, you are better off with a whole-house dehumidifier. In such cases, the unit will be connected to a pre-existing central air or heating system. You can also opt to get it installed on its own. These can work for areas up to 3000 square feet. It’s no secret that these are fairly expensive – at least initially – but you’ll enjoy savings in energy and money eventually since they’ll make your air conditioner/s work efficiently.
Desiccant dehumidifiers create a cooler space. You can pick from either desiccant or refrigerant dehumidifiers. Desiccant models often have lower capacity ratings than the refrigerant counterparts, but they work better in places that have low temperatures. So if your room typically falls below 65°F, you can do better with desiccant dehumidifiers. These are also more silent than refrigerant units.
Refrigerant units are the opposite of desiccant models. These are best suited for humid and hot rooms. They have higher capacity ratings and are more effective when placed in areas of high temperatures. You need to take note of this because if you operate a refrigerant unit in temperatures below 65°F, it can experience problems and damage from the ice that can form on its evaporator coils.
Determining the Capacity You Need
The capacity that you need depends on how damp your bathroom is. Like the size of the room, you’ll need to measure this one, too. You can check this using a humidity meter, which can be very accurate. But for this particular purpose, you don’t need to be ultra-precise. You only need to obtain a general idea of how damp the room is. You’ll only need to check for the obvious signs of humidity, such as damp spots on walls and the presence of condensation in the windows.
Here are the four levels of dampness/wetness:
- Moderately Damp – when the air feels damp and clammy. There is often a musty smell during humid weather.
- Very Damp – when you smell musty odors, and the air feels damp. There might be damp spots on walls and on the floor.
- Wet – there are water beads formed on walls and floors. There is moisture that seeps around the room’s edges. You feel and smell dampness consistently.
- Very Wet – there is visible standing water on the floor.
Let’s find out which dehumidifiers are ideal for each level of dampness.
Moderately Damp Spaces
For moderately damp rooms, you need a dehumidifier with a capacity of 10 to 26 pints. This capacity (or size) refers to how much water can be extracted from the air in a span of 24 hours. If your room is only somewhat damp, there is no need for an ultra high capacity unit. The capacity depends on the size of the space.
Here are the standard recommendations for moderately damp areas:
- Space: 500 square feet = 10-Pint dehumidifier
- Space: 1000 square feet = 14-Pint dehumidifier
- Space: 1500 square feet = 18-Pint dehumidifier
- Space: 2000 square feet = 22-Pint dehumidifier
- Space: 2500 square feet = 26-Pint dehumidifier
Very Damp Spaces
Go for 12 to 32 pints of capacity if you have a very damp room. These areas need slightly higher capacity and you’ll also need to consider how big the space is.
Here are the standard recommendations for very damp areas:
- Space: 500 square feet = 12-Pint dehumidifier
- Space: 1000 square feet = 17-Pint dehumidifier
- Space: 1500 square feet = 22-Pint dehumidifier
- Space: 2000 square feet = 27-Pint dehumidifier
- Space: 2500 square feet = 32-Pint dehumidifier
Go for dehumidifiers with 14 to 38-pint capacities for wet spaces.
Here are the standard recommendations for wet areas:
- Space: 500 square feet = 14-Pint dehumidifier
- Space: 1000 square feet = 20-Pint dehumidifier
- Space: 1500 square feet = 26-Pint dehumidifier
- Space: 2000 square feet = 32-Pint dehumidifier
- Space: 2500 square feet = 38-Pint dehumidifier
Very Wet Spaces
For very wet spaces (where there is obvious, visible standing water on the floor), go for 16 to 44-pint capacities. These are the highest capacities available in the market.
Here are the standard recommendations for very wet areas:
- Space: 500 square feet = 16-Pint dehumidifier
- Space: 1000 square feet = 23-Pint dehumidifier
- Space: 1500 square feet = 30-Pint dehumidifier
- Space: 2000 square feet = 37-Pint dehumidifier
- Space: 2500 square feet = 44-Pint dehumidifier
Dehumidifiers are great accessories to have at home because they eliminate the excess moisture, particularly from indoor spaces. We hope this buying guide has been helpful in choosing the right bathroom dehumidifier for you. Let us know which one you picked in the comments section!
