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 Frigidaire 22 Pint Dehumidifier is a solid choice for managing humidity in small bathrooms or rooms up to 1,500 square feet. Its 22-pint capacity allows it to efficiently remove a good amount of moisture daily, helping reduce mold growth and improve air quality. The size is fairly compact at about 19.5 inches tall and 15.5 inches wide, making it portable enough to move around but still substantial enough to handle a small room’s humidity needs.

It weighs 35.5 pounds, so while it’s not ultra-light, the front-loading water bucket with a convenient handle makes emptying easier. The unit includes a washable filter, which simplifies maintenance and keeps the air cleaner without extra costs for replacements. Another user-friendly feature is the automatic shut-off when the bucket fills, plus a continuous drain option that lets you bypass emptying entirely if you have a drain nearby. This is especially handy for bathroom setups.

With three speed settings and a 'sleep' operation mode, it can run quietly enough not to disturb you, though it’s not the absolute quietest model out there. Energy-wise, it uses 152 watts, which is reasonable for its capacity but something to keep in mind for longer use. Some users might find it a bit bulky for very tight spaces, and it doesn’t have advanced smart features, but its straightforward controls and reliable performance make it a practical pick for anyone needing to tackle high humidity and mold in small to medium bathrooms.
