Choosing the right crawl space dehumidifier for your home

Your home’s crawl space provides easy access for plumbing, electrical and structural repairs.

But if proper precautions are not taken to prevent high humidity levels, your crawl space can easily become a breeding ground for mold, musty odors pests and microscopic organisms which thrive in damp, dark, cold conditions.

A crawl space dehumidifier can help. It will remove excess moisture from your crawl space air and pump it outside to drain. Crawl space dehumidifiers improve not only the air quality of crawl space, but of your entire home.

Dehumidifiers can prevent mold and water damage.

It’s a simple fix that protects the health of your home and family.

As the warm air from your living space rises and escapes through attic vents, the cold air from your crawl space travels upward to replace it. This is called the ”stack effect,” and it is why mold in your crawl space can spread upward to your home. And, because mold and microorganisms can aggravate your children’s asthma, allergies and other respiratory conditions, it’s important to your family’s health to install a crawl space dehumidifier with a pump.

Before you commence with a crawl space dehumidifier installation, though, you need todo your research. Here’s what to look for:

  1. The capacity of your dehumidifier to remove water from the air
    It seems that this should go without saying, but often people rush into buying the cheapest model without much research. High-quality de-humidifiers have high ‘gallons removed per day,’ meaning that they are able to remove quite a bit of moisture from your crawl space’s air.This is, after all, the chief purpose of your crawl space dehumidifier. In addition to reading product descriptions be sure to parse through Hydrabreeze crawl space dehumidifier reviews—as well as other brands—to see the real-life capacity of the dehumidifier as well.
  2. Your dehumidifier’s airflow
    In order to effectively reduce the relative humidity (RH) of your crawl space, all of your crawl space’s air must flow through the dehumidifier every couple hours. To accomplish this, your dehumidifier must have a powerful fan and a high air flow as measured in CFM (cubic feet of movement per minute). Usually, you can look through crawl space dehumidifier reviews to see what past users have thought of the airflow. We use the Hydrabreeze dehumidifier, which can remove an astonishing 110 pints per day. Most compact models provide only 70 pints per day of water removal.
  3. Look for a dehumidifier with a pump
    Unless you want togo into your crawl space every so often to empty your dehumidifier’s reservoir, it’s important to look for dehumidifiers that come with pump. These pumps will direct the water removed from the air outside to drain away from your house.
  4. Installation company
    The crawl space dehumidifier installation company you choose is just as important as the actual equipment. In order for itto work, it needs tobe installed correctly. Usually, your dehumidifier needs tobe paired with a ventilation system, vapor barrier and a drainage system. Helitech can point you toward the right crawl space air system for your home.
