What Should You Look For In A Whole House Dehumidifier?

There are many factors to consider when purchasing a dehumidifier for your home.  We’ll help you understand the various types of dehumidifier, as well as common features to look our for, like size, hose, capacity, and noise level.

Different types of dehumidifiers

There are several kinds of dehumidifiers to consider when you start your search, and not everyone will need a whole house dehumidifier.  Below are the main types of dehumidifier currently available on the market.

Thermo-Electric Dehumidifier

A Thermo-Electric Dehumidifier is an affordable option for a single room unit. It cools the air while it dehumidifies like an air conditioning unit. The air is condensed and cooled while the machine works to removes the excess humidity.  This type of dehumidifier is good for higher temperatures, for example during the summer months.  This type of unit is perfect for single rooms or bathrooms.

Desiccant Dehumidifier

A desiccant dehumidifier uses a chemical, or a desiccant, to remove excess humidity from the air.  Compared to typical compressor dehumidifiers, the desiccant dehumidifier is a compact and quiet unit made for a bedroom or small space.

Portable Dehumidifier

The portable dehumidifier is a larger unit that can be moved around between rooms. The unit comes with wheels which makes this easier to move from room to room. It is typically large enough to dehumidify larger rooms, but not large enough to work effectively on an entire house.

Small Dehumidifier

A small dehumidifier is perfect for bedrooms or other smaller rooms. They are not strong units, but they are a cost-effective option for a humid space like a bathroom or kitchen.

Whole House Dehumidifier

A whole-house dehumidifier (the models we are reviewing in this post) are great option, which save you the hassle of moving a dehumidifier between rooms and floors of your house. They are larger and often require professional installation directly into your home’s HVAC system.  But once installed, they typically require minimal cleaning and maintenance.  They are very easy to control through a humidistat (similar to a thermostat), and they often have convenient features such as auto-shut on / off.

They are a great option for large areas, and are effective at removing excess humidity from the air.

Commercial-Grade Dehumidifier

Commercial-grade dehumidifiers are large units found in buildings or warehouses. Most people do not need a unit this large, but they are great for small businesses and offices.

Industrial Grade Dehumidifier

Industrial grade dehumidifiers are extremely large units that fit in most large warehouses or other types of commercial buildings.  This would not typically be a humidifier for your average home owner or small business owner.


The size of your home dictates the capacity of the dehumidifier you need; i.e., the larger the home, the larger the capacity you’ll need. Typically, residential dehumidifiers come in the following sizes:

  • 30 – Pint: powerful enough to remove the humidity from smaller homes. 30-pints of moisture are extracted from the air in twenty-five hours. They are also good for single bedrooms or smaller areas.
  • 50 – pint: strong enough to be a commercial-grade or a whole-house dehumidifier. It is a good unit for larger spaces and can absorb the moisture in the air without being moved. It is a good unit for very wet areas or places prone to flooding.
  • 70-Pint: works to extract at least 70 pints of water every 24-hours from the air. Their size and capacity make them perfect for working in a warehouse or other type of large space.

Other Considerations

Dehumidifier With A Pump

A pump is not required for a dehumidifier to work, but it is a very convenient option to have. It makes it so you will not need to empty the water reservoir by hand on a regular basis. If the dehumidifier has a pump, it will come with a tube that can connect directly to your drainage system, or a sink or window to the outdoors.  This is a feature you should consider when purchasing a whole house dehumidifier.

A pump-based dehumidifying system is a good option to have in more humid areas. You will save yourself time from having to consistently drain the unit or having it automatically shut off when it is full. The automatic shut-off is a safety feature to prevent the unit from overflowing and flooding all over your house.

Noise Level

Most people would love the idea of a silent unit, but those are not always the best functioning units. If you are placing this unit in a place like a bedroom or a family room, you do not want it to make too much noise while it works. The larger capacity the unit, the more likely it will be to be noisier.

A noisy dehumidifier is not a problem in a place like a warehouse, but if it is going in your home, you might choose a smaller and subsequently, quieter unit.

Benefits of A Whole House Dehumidifier

There are many benefits to having a whole house dehumidifier installed.  First, as we’ve said before on this blog, it is recommended to keep your home at a humidity level between 30% – 50%.  Installing a whole house dehumidifier is an effective and efficient way to maintain this ideal humidity level throughout your home.  This helps to prevent mold and other allergen growth, to keep you and your loved ones comfortable and healthy, and to keep you home furnishings in great condition.
