10 Best Small Bathroom Dehumidifier For High Humidity And Mold 2025 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 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 BREEZOME 60 OZ Dehumidifier is a strong candidate for managing humidity in small bathrooms and similar spaces. It offers a decent moisture removal capacity of about 700ml per day, which suits areas up to 350 square feet, making it effective for typical small bathroom sizes. The 1.8-liter water tank is relatively large for this type of unit, so you won’t need to empty it very often. Plus, the auto shut-off feature stops the machine when the tank is full and alerts you with a red light, which helps prevent overflow and hassle.

This model is compact and lightweight, with a built-in handle making it easy to move around, which is handy if you want to use it in different rooms or in an RV. Its quiet sleep mode runs at a noise level of around 35 decibels, so it won’t disturb you at night—a bonus if you want to run it in the bathroom close to your bedroom. Energy efficiency is quite good, consuming only about 1.15 kWh over a 24-hour period, and the built-in timer offers flexible operation from 12 to 48 hours, helping avoid unnecessary power use. Maintenance is straightforward, with a washable filter and an automatic defrost feature that ensures the machine continues running well even in cooler environments. The colorful adjustable night light is a nice touch for ambiance but might be unnecessary in a bathroom setting.

Some minor drawbacks include its maximum operating temperature capped at 30°C (86°F), which limits use in hotter climates, and the modest dehumidification capacity compared to larger units if you have very high humidity. This dehumidifier is a quiet, portable, and energy-friendly choice suitable for small bathrooms facing moderate humidity and mold concerns.
