Too much moisture can damage your house, personal items, and health. Enter dehumidifiers. They come in all shapes and capacities with several features to consider. The thousands of dehumidifier reviews, questions, and comments can be overwhelming too, so the House Method Reviews team did the work for you.

Excess moisture can be a major problem in some regions or sometimes even just certain homes. Moisture in your home creates that “sticky” feeling—like you’re walking into a tropical forest—that’s simply unpleasant to come home to. That feeling not only affects the air, but your home’s interior as well as your clothing, food, and health. The moisture can result in potentially dangerous traces of mold, mildew, and bacteria.
In any scenario, a dehumidifier is a step in the direction of immediate change in moisture levels and comfort of your home. They can be used temporarily to halt a major issue, like mold infestation, or you can use one regularly to keep water levels low and prevent mold and mildew from forming.
We’ve chosen five of the best dehumidifiers that can help keep the air in your home crisp and clean. These products can sometimes be costly though, so it’s important to know your machine will be reliable and effective. The products we reviewed above have proven themselves to us and many verified customers, like you. If you’re unsure how it works or what to look for, refer to our guide below before you buy.
Dehumidifiers use fans to draw air into the unit. When the air passes through the unit, cooling coils pull moisture from the air by lowering its temperature. The removed moisture is collected in a reservoir. Then, it heats the air and distributes it back into the room moisture-free.
You have two options for water collection in your unit. You can either collect water in a bucket, which you will need to empty once it has reached capacity, or you can set up a hose to continuously empty water into a sink or floor drain. The right option for you depends on the moisture levels in your home, the maintenance level you want (or want to avoid), and how much you’re willing to spend on your electric bill to power the machine. Review the product details to find out whether the hose is included with your purchase. Sometimes they include outlets but not the hose itself, so you may need to purchase one separately.
You can find dehumidifiers with different features and controls, but all work in the same fundamental way. They pull moisture from the air in the surrounding area, separate moisture from the air, and return the air back into the room to make your space more pleasant and safer.”
These machines come in a range of sizes to fit your different needs. Small dehumidifiers—about 16-ounce capacity—are great for low-grade moisture issues in small rooms, like closets or bathrooms. If you need to cover more space, like a living room or open floor plan home, go for a larger machine that has a 50- to 70-pint capacity.
Many dehumidifiers allow you to set the humidity level you’d like it to maintain. After you set the humidity level, the unit should automatically shut off once the level is reached. This is important for heavy-duty machines that can sometimes overcorrect the issue and create dry, uncomfortable air. If you’ll want this feature, be sure to check for humidistats and humidity control settings on your unit.
If you’re dealing with serious moisture issues, continuous mode might be the choice for you rather than an automatic shut-off, which could only scratch the surface of your moisture problem. For continuous mode, use the drain hose rather than the bucket to avoid overflowing from the reservoir. Look for energy efficient dehumidifiers to reduce electricity usage as much as possible.
High humidity (more than 50% humidity) at home can increase allergens and mold problems, but air that is too dry (less than 30% humidity) can make asthma worse.”
Look for the following signs to know if you need to address the moisture in your room or home: traces of mold on ceilings or walls, condensation on windows, musty odors, worsened allergies or congestion.”
Don’t forget to clean your dehumidifier filter, especially if it runs frequently in a moist, less-than-sparkling-clean area, like the basement.”
For legitimate dehumidifying needs—think large spaces or a home with a lot of moisture—the best choice is . It has a 70-pint capacity and customizable settings to get the humidity levels and runtime just right. It works well, fast, and it’s not too bad to look at either.
The size of the area you’re working with will determine how large of a dehumidifier you need. Mini dehumidifiers (like the ) are great for small rooms and typically run with a few gallons of capacity if you hook up a hose for continuous use. If you’re using yours in an open floor plan or basement, consider 50- to 70-pint dehumidifiers, such as the or .
Price is based on size and capacity. Small dehumidifiers range from $40 to $80. Mid-sized to large dehumidifiers cost between $130 to $200.
Dehumidifiers can run up your electricity bill if you overlook usage amounts or the energy efficiency of your machine. Reduce costs by putting your unit on auto shut-off and look for units that are Energy Star compliant.
Many dehumidifiers are energy efficient. Look for the energy factor detail in the product description. The energy factor is measured in liters of water removed per kilowatt-hour (L/kWh). Units labeled as Energy Star compliant is a more obvious indicator that they’re energy efficient.
Note: Continuous mode means the fan will not shut off until it’s manually turned off. This mode is better for bigger problems (a flooded basement) that require constant air circulation and continuous drainage. However, it’s more maintenance if you don’t fasten a hose to the unit instead of relying on the bucket, which can easily overflow if forgotten.
