What are the features of garage dehumidifiers?

Before you purchase the first dehumidifier you find, it would help to familiarize yourself with the different features of this home appliance.

1.    Pint Capacity

This feature refers to the number of moisture measured in pints that can be removed from the air within 24 hours. Usually, for an average sized garage or home, a 70-pint dehumidifier would be enough.

2.    Collection Container

4.    Humidistat

This feature measures the relative humidity of the area. It is an essential feature that provides the dehumidifier with information it needs so it can adapt to the settings. Some dehumidifiers are equipped with this measuring device while others don’t have. A built-in humidistat adds convenience but it’s not a necessity.

5.    Low-Temperature Feature

The auto-defrost feature is necessary for the dehumidifier to operate in low temperatures. Most models are designed to operate in normal room temperature but cannot handle very cold temperatures. If you live in a region where climate can get extremely cold, you may need one that has an auto-defrost function.

6.    Auto-restart and auto-shutoff feature

Majority of dehumidifiers now have an auto-start function that automatically turns the unit on after a power interruption. With this feature, you do not need to re-set the machine every time the power shuts. Meanwhile, the auto-shutoff function works by stopping the dehumidifier once tank is full.

7.    Continuous Drainage System

The best garage dehumidifier is equipped with a built-in hose for continuous drainage. With this feature, you do not need to frequently empty the collection tank every time it fills up. If you plan to run the machine 24/7, then be sure to pick a model with continuous drainage system.

8.    Permanent or portable

Dehumidifiers can either be portable or permanent. You can decide whether it will be anchored permanently at the garage or you plan to move it around your home. Usually, portable dehumidifiers are smaller, weigh less, and have caster wheels. Meanwhile, permanent dehumidifiers often require installation by a professional.
