When looking for the best whole house dehumidifier, you will notice that the options available are endless. 

Choosing the best one can be pretty tricky, but our guide will help you through the process, so keep reading. 

What Features to Look for When Buying a Whole House Dehumidifier 

Energy efficiency

Consider a humidifier that comes with DOE or EPA issued certification (Energy-Star). This is to make sure that a third party has tested the unit for its energy efficiency.   

Overall capacity

Go for a device rated for dehumidifying the entire house and not just the room. Due to their high capacity, these units are bigger and cost more than smaller dehumidifiers. 

Modes

Consider different features and modes available in different brands. Smart features are always handy, and automatic shut-off will also help in reducing costs. Automatic timers are a pretty continent too. Different energy saving and power modes are available too. 

Types of Whole House Dehumidifiers

Compressor-based units

These units have compressors in them, and they work like an air conditioner. They come with a refrigerant and cool down the warm air they suck in. The moisture within the air turns into liquid and drips into a tank. The cool air is free from any moisture and passes through a heating element, which warms the air back to its original temperature. 

Chemical absorbent-based units

These humidifiers remove moisture by absorbing the damp air into a drying material. These desiccant dehumidifiers are fixed units, and you can connect them to your HVAC system. However, these units consume a lot of energy and are not very economical. 

Dehumidifying ventilators

These are mostly present in basements, but they are not very popular. They come with an exhaust fan and a sensor. The sensor works just like a thermostat and triggers the system when the set humidity level is reached. These are a bit less effective as compared to the other two types. 

Are whole house dehumidifiers noisy? 

Whole house units are bigger, so they might be slightly noisy. But they are not going to be anything that irritates your ears. It is best to check the reviews to buy a unit.

Do these units come with washable filters?

You can choose between washable filters and replaceable filters. It is always a good idea to go for a washable filter because you can repeatedly use them instead of buying new filters every time. 

Where does the water go in a dehumidifier? 

Whole-house dehumidifiers can drain plenty of water throughout the day during wet weather. Therefore, a continuous drain is mandatory. But the good thing is that these units can automatically drain themselves. Some humidifiers have an inbuilt pump, while others need gravity for regular drainage.
