What To Look for in a Good Dehumidifier for a Small Bathroom

Don’t forget to consider the following factor when you’re deciding what dehumidifier to get for your space.

First things first, capacity. Dehumidifiers are available in various sizes with different moisture removal capabilities. For a small bathroom, a compact unit with a capacity of 20-30 pints per day would typically be sufficient.

Second, look at the energy efficiency. It’s important to find a dehumidifier that won’t significantly increase your electricity bills. Look for models with an Energy Star rating, as these are designed to consume less energy while still providing effective moisture removal.

Pay attention to the noise level. Considering that dehumidifiers could be running for hours, you’ll probably want to find one that operates quietly, especially if your bathroom is near your bedroom. Ideally, you’ll want a dehumidifier with a noise level below 50 decibels.

Don’t overlook ease of use when searching for the perfect dehumidifier. Look for features such as user-friendly controls, a clear display, and straightforward setup and maintenance instructions.

Finally, consider the drainage system. Some dehumidifiers have built-in pumps that allow for continuous draining, while others rely on manual emptying of a water tank. Choose a model that fits your personal preferences for convenience and ease of use.

Frequently Asked Questions

Do small dehumidifiers work well in bathrooms?

Yes, small dehumidifiers work effectively in bathrooms, especially when space is limited. They can help maintain proper humidity levels, preventing mold and mildew growth. While they may not be as powerful as larger models, they are generally sufficient for managing moisture in a small bathroom.

What type of dehumidifier works best for small bathrooms?

For small bathrooms, we recommend either a compact compressor-based dehumidifier or a desiccant dehumidifier. Compressor units are energy-efficient and can remove large volumes of moisture, while desiccant models are quieter and work well at lower temperatures.

Absolutely! Compact dehumidifiers are versatile and can be used in various spaces, including apartments and bathrooms. Just ensure that you select a unit with the right capacity to handle the room size and moisture levels. When not in use in the bathroom, you can easily move it to another part of your apartment to tackle humidity elsewhere.
