Crawl space fans are essential tools for managing air circulation and controlling moisture under your home. Without proper airflow, crawl spaces can trap humidity, leading to mold, mildew, wood rot, and unpleasant odors that may rise into your living space. Crawl space fans help move air through the area, reducing moisture and discouraging the growth of harmful contaminants. The most effective systems, like ATMOX, use intelligent technology with sensors to power fans only when conditions are right—based on dew point, not just time of day or season. This targeted approach maximizes moisture control without wasting energy. Crawl space fans can also control the dehumidifiers, improving overall efficiency and keeping air evenly distributed. Whether you’re looking to prevent moisture issues or improve indoor air quality, fans are a key component of a healthy crawl space system.
Understanding the relationship between changes in season, geography, and dew point is crucial for maintaining a healthy crawl space environment. Managing moisture levels in your crawl space is important for maintaining the structural integrity and indoor air...
Crawl spaces have evolved into two main categories: Vented and Unvented (also referred to as Closed). The International Residential Code (IRC) has specific regulations for moisture control for both vented and unvented crawl spaces. For the purposes of this blog, we...
What is Indoor Air Quality? Indoor air quality (IAQ) has received a lot of attention over the last several years. The increased interest in this topic is likely due to the link between indoor air quality and your health. Additionally, the number of hours that we...
A dehumidifier is a great moisture reduction tool for the crawl space. However, the cost to run a dehumidifier can greatly impact your energy cost. How does a dehumidifier work? The dehumidifier’s internal fan pulls warm moist air in and then cools the air. Cold...
Why Does My Crawl Space Smell? It is no surprise that crawl spaces are often the culprit for bad smells in your home. These dark cool areas of your home are often dirty and can be a host for mold, bugs, animals and other issues. It is not a place we spend much...
Should crawl space vents be open or closed? Like we have frequently said before, the ATMOX answer is that “it depends.” What is the situation? What are you trying to accomplish? And, what type of crawl space setup do you have? Vents in a Traditional Vented Crawl...
Crawl Space Dehumidifiers and Humidity Levels Let’s explore a commonly used tool in the crawl space – a dehumidifier. And, let's look at how we can improve the use of crawl space dehumidifiers. A dehumidifier works to remove humidity from the air by drawing the...
Over the past several decades, construction preferences and styles have evolved and changed. In some styles, such as bungalows, minimal traditional and cape cod style homes from the 1920s to 1950s, the layouts stayed mostly within a rectangular frame. Once the...
Crawl space ventilation fans work as an excellent tool to dry a crawl space, BUT it is critically important to use them at the right time. If you’ve been researching crawl spaces before landing on this blog, your head is probably spinning. There are so many, many...
Let's bust this myth: ATMOX fans are just fans on a humidistat. ATMOX fans are generally connected to a controller. That controller is much more sophisticated than a simple humidistat. Let's explore what makes a crawl space setup or "ATMOXsphere" different. ATMOX...
