10 Best Small Bathroom Dehumidifier For High Humidity And Mold 2026 in the United States

The TABYIK 35 OZ Small Dehumidifier is designed for use in small rooms, bathrooms, RVs, and closets, making it suitable for spaces up to 280 sq. ft. With a capacity to collect up to 16 oz of water per day, it performs reasonably well in high humidity conditions. Its compact size (5.9 x 5.9 x 10.1 inches) and lightweight build (2.19 pounds) make it easy to move and place anywhere.

Additionally, it features auto shut-off protection, which ensures safety by stopping operation when the water tank reaches 700-800ml full. The transparent 35 oz tank allows you to monitor water levels easily, and the groove design facilitates straightforward water disposal and cleaning. The dehumidifier operates quietly at 28dB, contributing to a peaceful environment, suitable for bedrooms and offices.

The colorful light feature adds a pleasant ambiance but might be seen as a gimmick by some users. Energy efficiency is commendable, with low consumption of less than 1-kilowatt hour per day. However, it lacks continuous drainage and advanced filtration, which might require regular manual emptying and cleaning. It's a practical choice for small spaces suffering from humidity and mold, but users looking for more advanced features might need to explore other options.

The KeepGlad Dehumidifier is a compact and efficient choice for spaces up to 1000 sq.ft., making it suitable for small bathrooms dealing with high humidity and mold issues. It can remove around 40 ounces of moisture per day, which helps reduce humidity from very high levels (around 80%) down to a comfortable 40%. This capacity fits well for small to medium areas but might be less effective in very large or extremely damp bathrooms. Its size is fairly portable and lightweight (under 6 pounds), so you can easily move it around as needed. Noise levels are impressively low, especially in sleep mode, operating quietly at about 28 decibels, which is great if you want to run it overnight without disturbances. Energy use is reasonable with a 90W power rating, and the inclusion of a timer helps save electricity by allowing you to set operating hours.

The dehumidifier also features an automatic shut-off when the 98-ounce water tank fills up, preventing spills, and it supports continuous drainage through a hose connection to avoid manual emptying—very convenient for regular use in damp spaces like bathrooms. Maintenance is straightforward with a washable air filter that traps dust and hair, keeping the airflow efficient and ensuring long-term use without high upkeep costs. The unit offers three fan speeds, letting you balance dehumidification power and noise. The added ambient 7-color lighting is a nice touch for creating a relaxing atmosphere but may not be essential for everyone.

While it covers many smart features, the maximum daily moisture removal may be on the lower side for very humid or larger bathrooms, and the plastic construction might affect durability over time. Its smart sensors, digital controls, and quiet operation make it a user-friendly option that meets many needs of a small bathroom dehumidifier focused on battling humidity and mold.

This compact dehumidifier is a solid choice for controlling moisture in small spaces like bathrooms, bedrooms, and closets, especially where high humidity and mold are concerns. It uses a dual-core semiconductor system to efficiently remove moisture from the air, which helps reduce dampness and creates a healthier environment. The 2.5-liter (85 oz) water tank and ability to cover up to 800 sq.ft make it suitable for small to medium rooms, though larger, very damp areas might require a bigger unit. Its size and light weight (around 5.5 pounds) make it easy to move around and place in tight spots, while the built-in handle adds portability.

Noise is kept low, especially in Sleep Mode where it operates under 30 dB, so it won't disturb sleep or quiet activities—ideal for bathrooms or bedrooms. Energy use is moderate at 80 watts, helping keep electricity costs reasonable. A handy 3-step timer allows you to set operation times between 8 and 24 hours, and the auto shut-off feature prevents overflow when the tank is full. For continuous use, the included drain hose is a convenient option to avoid manual emptying. Maintenance is straightforward with a reusable filter that can be cleaned, but users should regularly check it to keep performance optimal. The added 7-color LED night light is a nice touch for those who want gentle illumination in the room.

The water removal rate (about 1 liter per day) is modest, so it may struggle in very humid or larger bathrooms. Also, while quiet, the fan might still be noticeable to extremely sensitive sleepers in the strongest mode. This dehumidifier is well suited for people looking for a lightweight, quiet, and easy-to-use unit to manage moisture in small bathroom spaces or similar areas prone to mold and humidity.
