How to Choose the Best Bathroom Dehumidifier?
When shopping for the best bathroom dehumidifier for your home, it’s critical to consider the bathroom’s size, the specific reasons you’re interested in lowering the moisture level, and how energy efficient each product is.
For smaller bathrooms, it’s easier to reduce your electrical costs by choosing a petite dehumidifier that will get the job done with low power output. You may need to spend more to get a dehumidifier that will be powerful and energy-conscious for larger spaces.
The Size of Your Bathroom
If you have a mid-large sized bathroom, you’ll want to look into standard-sized dehumidifiers that offer more power. In contrast, you can choose a mini dehumidifier that you put on the counter or toilet tank in a smaller bathroom.
Mini dehumidifiers are much more affordable and use less energy. However, they also have a smaller tank capacity and must be emptied more frequently.
To ensure you’re selecting an energy-efficient dehumidifier, look at products that are marked as Energy Star certified. Energy Star certified dehumidifiers use roughly 15% less energy than the standard model. They achieve this energy efficiency by implementing more energy-efficient refrigeration coils, compressors, and fans in the dehumidifier’s design.
Decrease energy consumption by selecting models with advanced functions to give you more control over how your dehumidifier is operating. Programmable timers give you the flexibility to have the dehumidifier turn on and off even when you’re not there to push the button manually, so it’s never operating unnecessarily and wasting power.
Multiple fan speed options also help give you a lower energy option while still leaving the device running. Digital displays that depict the current humidity level are useful, and some mechanisms allow you to input a target humidity level and increase efficiency.
The capacity or tank size of a dehumidifier is measured in pints per 24 hours. It will determine how long your dehumidifier can be left running before you need to empty the water. The capacity you need depends on the bathroom’s size and the humidity levels in it.
It’s ideal for a slightly damp space to have a dehumidifier with a capacity of 20-30 pints per 24-hours, whereas for a room that is consistently damp and smells musty, you should choose a unit with a 25-40 pint capacity. If your area is wet, for example, there is leaking or wet laundry drying, an even higher capacity of 30-50 pints per 24-hours will serve you better.
If you’re unsure as to what size water capacity is best suited to your bathroom needs and you haven’t used a dehumidifier in there before, it’s better to choose a size up rather than be left with a tank that’s too small and needs to be emptied frequently.
Final Verdict: Our Top Choice
Our top choice for a bathroom dehumidifier is the TOSOT Energy Star Dehumidifier, which offers easy to use digital controls that provide low energy consumption options. The TOSOT is an Energy Star certified product, so you can count on keeping your utility costs down.

You can also opt for a convenient hose connection to continuously drain the water. This is a reasonably priced dehumidifier that is powerful enough to keep your bathroom dry and fresh.
