Why Dehumidifiers For Crawl Spaces are a Must-Have

As a homeowner, I never really paid much attention to the crawl space under my house. It was just a dark and damp area that I rarely ventured into. However, all of that changed when I started noticing musty odors in my home and even some mold growth in the corners of my walls.

After doing some research, I learned that crawl spaces are notorious for high humidity levels due to their proximity to the ground and lack of proper ventilation. This excess moisture can lead to a host of problems, including mold growth, wood rot, and even structural damage.

That’s when I realized the importance of having a dehumidifier in my crawl space. Not only does it help reduce the humidity levels, but it also prevents mold growth and protects the integrity of my home’s foundation. Plus, with less moisture in the air, there is less chance of musty odors lingering around.

Another reason why dehumidifiers for crawl spaces are necessary is for improved air quality. The air in our homes circulates from top to bottom, meaning any contaminants or allergens present in the crawl space can easily make their way into our living spaces. By keeping the humidity

My Buying Guide on ‘Dehumidifiers For Crawl Spaces’

As someone who has dealt with mold and musty odors in my crawl space, I understand the importance of investing in a good dehumidifier. Crawl spaces are often damp and poorly ventilated, making them the perfect breeding ground for mold and mildew. A dehumidifier can help control the humidity levels in your crawl space, preventing mold growth and improving air quality. In this buying guide, I will share my experience and provide you with important factors to consider when purchasing a dehumidifier for your crawl space.

1. Size and Coverage

The size of your crawl space is an important factor to consider when buying a dehumidifier. You want to make sure that the dehumidifier is capable of effectively removing moisture from the entire space. Measure the dimensions of your crawl space before purchasing a dehumidifier. Most manufacturers will provide information on the square footage that their product can cover. It is best to choose a dehumidifier that can cover a slightly larger area than your crawl space to ensure maximum efficiency.

2. Type of Dehumidifier

There are three main types of dehumidifiers – refrigerant, desiccant, and whole-house. Refrigerant dehumidifiers work by cooling the air to condense moisture, while desiccant dehumidifiers use a drying agent like silica gel to absorb moisture from the air. Whole-house dehumidifiers are installed in your HVAC system and can control humidity levels throughout your entire home. For crawl spaces, refrigerant or desiccant dehumidifiers are recommended as they are specifically designed for enclosed spaces.

3. Drainage Options

Dehumidifiers collect water from the air which needs to be drained regularly. Most models come with either a built-in pump or gravity drainage options. Built-in pumps are convenient as they can pump water out through a hose without requiring any manual effort on your part. Gravity drainage requires you to place the unit near a drain or window where you can direct the collected water out using a hose.

4. Energy Efficiency

Since your dehumidifier will be running constantly in your crawl space, it is important to consider its energy efficiency rating before making a purchase. Look for models with Energy Star certification as they consume less energy compared to non-certified units.

5. Noise Levels

If you have ever heard a loud appliance running constantly, you know how bothersome it can be especially if it’s located near living areas in your home. Consider models with lower decibel levels (dB) if noise is an issue for you.

6. Additional Features

Some other features that may be worth considering include auto-shutoff when the water tank is full, easy-to-use controls, adjustable humidity settings, and timers which allow you to schedule when you want the unit to run.

In Conclusion

Investing in a good quality dehumidifier for your crawl space can save you from potential health hazards caused by mold and mildew growth as well as improve air quality in your home overall. Be sure to consider factors such as size coverage, type of dehumidifier, drainage options, energy efficiency rating, noise levels, and additional features before making a purchase decision.
