How to Choose the Right Bathroom Dehumidifier

There are several factors you need to put into consideration when buying a bathroom dehumidifier;

• Coverage area

Different dehumidifiers have different coverage areas- this is the area a dehumidifier can effectively extract moisture from the bathroom. In most cases, this is expressed in volume form in terms of square feet, cubic feet, or Square meters.

Before you purchase a dehumidifier, it is important that you check the features of your unit and also get the estimated volume of your bathroom. You can easily calculate the volume of your bathroom by taking measurements for its height, length, and width. Multiply these measurements to get the volume in cubic meters.

When buying a humidifier, make sure that it exceeds the volume of your bathroom as erring on the lower side will make it inefficient in its job.

• Energy efficiency

Dehumidifiers with Energy Star certifications are better than those lacking this certification as they use less energy. This not only helps you save on energy bills but also in environment conservation.

Therefore, choose an Energy-Star rated unit if you want to reduce your energy cost at home. The savings will go a long way in making your unit economical and cheaper.

• Tank capacity

If you are to go for a dehumidifier that requires you to manually empty the tank, then you need to put tank capacity into consideration. The best bathroom dehumidifier should have larger water tanks so that you don’t have to empty them often.

To figure out how often you will be needed to empty the content of your dehumidifier tank, divide the tank capacity by the tank size. For instance, a unit with a 20 oz. tank and a moisture removal rate of 9oz per day mean that you will need to empty the tank every two days.

• Dehumidifying rate

This shows the rate at which the dehumidifier can pull moisture from the bathroom in a day. The rate is normally expressed in pints, Oz, or gallons in a day. A good way of knowing how much humidity needs to be removed from your bathroom, use a hygrometer.

A hygrometer will give you accurate humidity levels in your bathroom, and this will help you know the right type of dehumidifier that you need.

• Self-draining capabilities

If you don’t want to be concerned about emptying your dehumidifier tank, then you need to invest in a unit with self-draining capabilities. Usually, these units come with a hose that connects to the tank, thereby allowing you to drain this water to your drainage pipe or sink.

If you plan on leaving the dehumidifier running continuously throughout, then this is an important feature to consider. It saves you from the need to regularly checking the tank and discarding its content.

Other features to keep in mind;

• Noise levels. Since most bathrooms are close to the bedrooms, you don’t want to have a noisy unit. therefore, check a unit with minimal noise levels
• Size and weight. This is a consideration for people with small bathrooms. Make sure to go for a compact unit that doesn’t take a lot of space

By keeping the above factors in mind, you will have an easier time choosing the best dehumidifier for bathroom.

Final Verdict

A perfect bathroom environment is one that’s free from odor and allergens. Since these are caused by excessive moisture, it is, therefore, logical to invest in a quality bathroom dehumidifier.

The above three dehumidifiers have been proven to be effective at eliminating excessive moisture from moist indoor surfaces. You can never go wrong by choosing any of these three dehumidifiers.
