Best Mini Compact & Small Dehumidifier for Home
A small dehumidifier will help keep allergens and the risk of mildew and mold growth at bay in bedrooms, bathrooms, and even RVs. They are ultra quiet and won’t prevent you from sleeping at night. We also include compact mini dehumidifiers that are perfect for closets, gun safes, jewelry armoirs, and watch drawers.
How We Chose the Best Small Dehumidifiers
We looked at many factors to decide which dehumidifiers were the best. A dehumidifier must be able to remove a lot of water from the air efficiently. The small dehumidifier needs to reduce the humidity levels in 250 square feet rooms from 80% to 45% relative humidity.
Our choices all have an automatic shut-off feature that turns the dehumidifier off when the water tank is full, preventing overflows because the basins are limited in size. We also considered the size of the dehumidifier. We chose whole-house dehumidifiers for larger primary bedrooms, basements, and living rooms, while you picked compact dehumidifiers for small spaces like an RV, closet, or bathroom.

What to Look for When Buying the Best Small Dehumidifiers
To choose the right dehumidifier for your needs, consider how much area it can cover and the size of its basin. Keep reading to learn more about these features and others important in a dehumidifier.
Look at the Dehumidifier Capacity
Dehumidifiers remove moisture from the air by turning it into a liquid. The liquid collects in a basin, and the dehumidifier’s capacity is how much water it can hold before needing to be emptied. A dehumidifier’s capacity for tiny rooms is about 10 to 27 ounces, while full-size versions may contain several gallons of water.
Dehumidifiers with a basin that lasts for 24 hours are ideal. Some come with an add-on bib that sends collected water directly into a floor drain, convenient for people using their basement dehumidifier near a floor drain.
Consider the Coverage Area
Dehumidifiers come in many different sizes to fit any area. A mini dehumidifier can work in an area of 100 square feet or less. The larger dehumidifiers can work in a room up to 300 square feet. The amount of space the dehumidifier can work depends on the size of the unit and how humid it is inside your house.
Manufacturers list the coverage area of their dehumidifiers in cubic feet. This helps you understand how much the dehumidifier can cover. If you have a standard 9-foot ceiling, you should use square footage to measure your space. But if you have vaulted ceiling height, use cubic feet instead.
Look at the Noise Level Settings
Dehumidifiers use a fan to circulate air through cooling coils that convert water vapor into liquid. It makes a noise similar to the noise made by window air conditioners. The bigger the dehumidifier, the louder it will be.
The noise produced by a dehumidifier is like a faint hum or the sound of people talking. Dehumidifier manufacturers are not required to disclose noise levels on their devices, but they may do so if they want to.
To figure out how loud a dehumidifier will be, read consumer reviews. It will give you a good idea of how loud the machine is. You can also try to place the device on a level surface to reduce noise.
Other Features You Should Look For
A few more features may distinguish one model from the next and make it the finest small dehumidifier for your needs.
Filtration: Allergies exist when there is a suitable environment for them to grow. For example, dust mites need at least 65 percent humidity to grow. Removing the moisture from your house may help avoid common allergy triggers such as animal dander, mold, pollen, and dust mites. These allergens can cause itchy or irritated eyes, wheezing, sneezing, and even chest discomfort. Many units include filters that help collect dust and other particles while keeping the unit functioning longer and keeping the space under your home cleaner.
Auto shut-off: Dehumidifiers with an automatic shut-off function prevent overflow of the water tank by turning off automatically when the basin is full.
