Dehumidifying Your Crawl Space: Regular Dehumidifier or Special Equipment?

No, a regular dehumidifier cannot be used in a crawl space. Crawl spaces require a specialized dehumidifier designed for low-clearance areas.

A crawl space is a confined area beneath a building or home that is often susceptible to natural moisture accumulation. This moist environment not only affects the structural integrity of the home but also causes mold growth and attracts pests.

Installing a dehumidifier in the crawl space aids in maintaining the relative humidity level and prevents mold growth and pest infestations. However, using a regular dehumidifier in a crawl space is not ideal as it may not fit into the limited space and may not function effectively due to the specific conditions of the crawl space. Specialized crawl space dehumidifiers consider the limited space, electrical requirements and long-term moisture buildup, making them the best choice for any crawl space.

Understanding Dehumidifiers

A dehumidifier is an appliance that removes moisture from the air and controls the humidity level in a room. It’s an essential tool to keep your crawl space dry and free from excess moisture. In this blog post, we will discuss different types of dehumidifiers, features of a regular dehumidifier, and the effectiveness and pros and cons of using a regular dehumidifier in a crawl space.

Different Types Of Dehumidifiers

There are two main types of dehumidifiers: refrigerant-based dehumidifiers and desiccant-based dehumidifiers. Both types function differently and have their unique characteristics.

Refrigerant-Based Dehumidifiers

Refrigerant-based dehumidifiers reduce the humidity level by drawing in moist air through a refrigerated coil. This coil cools the air below its dew point temperature, causing the moisture to condense and collect in a water tank. Refrigerant-based dehumidifiers are more suitable for larger crawl spaces as they have a higher capacity.

Desiccant-Based Dehumidifiers

Desiccant-based dehumidifiers absorb moisture from the air using a desiccant material like silica gel. Unlike refrigerant-based dehumidifiers, desiccant-based dehumidifiers do not cool the air. They are more energy-efficient and ideal for smaller crawl spaces.

Features Of A Regular Dehumidifier

Regular dehumidifiers are designed for residential use and are suitable for controlling the humidity level in an average-sized room. They come with several features that make them easy to use and maintain.

• Automatic shut-off: When the water tank is full, the dehumidifier automatically shuts off, avoiding overflow and unnecessary energy consumption.
• Adjustable humidistat: A humidistat allows you to set the desired humidity level and maintain it automatically.
• Air filter: Most dehumidifiers come with washable air filters that trap impurities and allergens, improving the air quality in your crawl space.

Effectiveness Of Regular Dehumidifiers For Crawl Spaces

Regular dehumidifiers can be effective in controlling humidity levels in crawl spaces. However, the effectiveness largely depends on the size of the crawl space and the humidity level. For smaller crawl spaces, a regular dehumidifier with a low capacity can do the job, whereas, for larger crawl spaces, a higher capacity dehumidifier will be necessary.

Pros And Cons Of Using Regular Dehumidifiers

Like any other appliance, regular dehumidifiers have their advantages and disadvantages. Here are some pros and cons of using a regular dehumidifier in your crawl space:
