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.

This dehumidifier is a solid choice for managing high humidity and preventing mold in small spaces like bathrooms, basements, or bedrooms up to 1000 sq.ft. Its 98 oz (about 6.1 pounds) water tank is large enough to reduce frequent emptying, which is convenient. The unit uses dual-core semiconductor technology, effectively removing up to 40 oz of moisture daily, suitable for small to medium rooms. It’s compact and lightweight at just under 6 pounds, with built-in handles making it easy to move around.

Noise-wise, it runs very quietly at less than 28 decibels, quieter than a library, so it won’t disturb your sleep or relaxation. Energy efficiency is addressed well with an automatic defrost system and smart power management that adjusts based on humidity, helping save about 20% on energy use. The auto shut-off feature activates when the tank is full or if the device isn’t placed correctly, preventing spills and making it safer to leave unattended. It also offers a 7-color ambient night light, which can be locked to your preferred color—nice for bathroom or bedroom use at night.

Maintenance looks straightforward with a removable tank and an air filter, though regular cleaning will still be needed to ensure optimal performance. This unit blends quiet operation, decent moisture removal, and convenient features in a compact design, making it well suited for small bathrooms prone to humidity and mold issues.

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.
