The Dehumidifier Buyer's Guide

If you are in the market for a dehumidifier to make your home, office or workspace a bit more comfortable you might not be sure where to begin. The information below helps you understand the two main types of dehumidifiers you have to choose from, and which features and functions will best serve your needs. Remember, heat-related humidity isn’t the only concern. If your bathroom has drip-like water stains on the walls, there is often condensation on your windows, your basement smells musty—many things could be the culprit, including humidity. You may also need a dehumidifier if you run a business where the plants, products, or inventory needs to be in a humidity-controlled environment.

The Two Main Types Of Dehumidifiers

The first thing you will need to decide when choosing your dehumidifier is whether you will need a refrigeration model or a desiccant model. Both can achieve your goals of eliminating humidity, and slowing the growth of allergy triggers which thrive in humid environments. That being said, desiccant models are only suitable for small rooms such as your bedroom, bathroom, or closet. Instead of extracting excess moisture from the air, they absorb moisture from the air—kind of like a sponge. There is no compressor and since moisture is not extracted, no tank to empty. If your room is small enough this can be a convenient option.

Refrigeration/compressor models are the most commonly purchased dehumidifiers, as they can effectively remove the humidity from medium and large rooms. They differ from desiccant models because they extract the warm air from the room. They have fans that draw in warm air. When the warm air comes in contact with the internal cooling coils, it turns the humidity in the air into condensation. These models are the fastest and most effective way of removing the excess water from large spaces, or humidity-specific spaces.

The Correct Option For Your Square Footage

Before you invest in any make or model, make sure it can accommodate the square footage of your room. If you are unsure of the square footage of your room, measure and multiply the length and width of the room. Dehumidifiers are measured by the pints of moisture it can collect over a 24-hour period, so you must determine how many pints matches your square footage. As a general rule of thumb, 30-pint models are effective for most small to medium sized rooms—such as your bathroom or bedroom.

50-pint models are ideal for living rooms and semi-open floor plans. 70-pint models are ideal for large open floor plans, attics, and average-sized basements. 100-pint models are will work for your larger homes, offices, and basements—or in under the home crawl spaces. The more pints your model collects, the larger it will be. For large spaces, the layout of your home or workspace will impact how far-reaching your dehumidifier will be. For multiple story homes you may need to have at least one on each floor.

If your dehumidifier is too small, it won’t get the job done—and if it is too large, it can have the negative effect, and remove too much moisture from your air. Signs your dehumidifier is too large, even though the humidity is removed, are that you are experiencing dry skin, bloody noses, cracked lips, or asthma or allergy flare-ups.

Your Refrigerator Models Must Have Proper Drainage

If a refrigerant/compressor model is the best fit for you, you must also consider which type of drainage is most convenient for you. After your humid air passes through the compressor coils, the condensation must have somewhere to go. Depending on the size and the model of your unit, this will either be a tray, reservoir, or a drainage hose. The larger the model the more likely you will have a drainage hose. For your convenience, most newer models have some sort of built-in auto shut off, but be sure to doublecheck.

If your dehumidifier has a continuous drain hose, you can drain the condensation in to a large bucket that won’t have to be emptied as often—or in to any nearby drain, shower, sink or sump hole. Some continuous drain hoses come with their own hose, but many can be fitted to a standard garden hose. If a garden hose is too long, simply cut it down to a more convenient size.

Advanced Features And Functions

Last but certainly not least, you must consider which advanced features and functions you would like built-in to your model. The more advanced your electronic and automated features, or the more features you have—the higher the price tag. However, to ensure you have the features and functions you require it may well be worth it. Just a few of these options include:

  • Automatic Restart – This will restart your dehumidifier at the same settings in the event of a power outage.
  • Wheels – If you plan on moving your dehumidifier from one room to the next, sturdy castor wheels can make relocation easy.
  • Washable Air Filter – Eliminate the need for an air purifier with a built-in filter that collects dusts mites, mold spores, allergens, and dust.
  • Timer – Conserve energy by setting a timer, or simply to automatically turn your dehumidifier on during the peak times of the day.
  • Fan Settings – Fan settings allow you to cool a room faster, or slow things down a bit.
  • Automatic Defrost – If you live in cold temps that go below 41 degrees the automatic defrost will keep your coils from freezing.
  • Humidistat – A humidistat allows you to not just dehumidify a room, but to control the precise level of humidity – such as in a greenhouse or climate controlled warehouse.


As you can see, there is a lot to consider before you select your first or next dehumidifier. On top of that, you must familiarize yourself with each make and models cleaning and maintenance needs. However, taking the time to consider both the feature and functions you require will ensure your humidifier meets all of your needs.
