10 Best Small Bathroom Dehumidifier For High Humidity And Mold 2025 in the United States

The hOmeLabs 1,500 Sq. Ft. WiFi-Enabled Dehumidifier is a solid choice for those dealing with high humidity and mold in small to medium-sized bathrooms. It can remove up to 22 pints of moisture per day, making it effective for improving air quality in spaces up to 1,500 square feet. The WiFi-enabled smart functionality is a great convenience, allowing you to control the dehumidifier remotely, which is perfect for maintaining the desired humidity levels without constant manual adjustments.

This model also features a modern, portable design with built-in wheels and handles, enhancing its portability and ease of relocation within your home. Additionally, its quiet operation ensures minimal disturbance to your daily activities or sleep. On the downside, weighing 36.3 pounds, it might be slightly heavy for some users to move around. Energy efficiency is a plus, as it runs continuously with an automatic shut-off when the tank is full, or it can be set up for continuous drainage.

The washable filter adds to its ease of maintenance, though regular cleaning is necessary to ensure optimal performance. For a bathroom with high humidity and mold issues, this dehumidifier offers effective moisture removal with added conveniences such as remote control and portability.

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.

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.
