Humidity control is critical for maintaining a healthy home—especially in areas like crawl spaces and attics where excess moisture can go unnoticed. High humidity can lead to mold growth, musty odors, insulation damage, and wood rot. It can also increase the risk of condensation, especially in colder months when warm indoor air meets cooler surfaces. ATMOX system’s controller address humidity by using sensors to monitor moisture levels and activate ventilation or dehumidification based on real-time conditions. This responsive approach ensures your home stays dry without wasting energy. By managing humidity, you protect your home’s structural integrity and improve indoor air quality. Even small increases in humidity can lead to big problems over time, so proactive control is essential. Whether you’re dealing with an encapsulated crawl space or a vented attic, humidity management should be part of your long-term home maintenance strategy.
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...
How effective is your dehumidifier in winter? The answer probably depends on when and where you are using it. Dehumidifiers used in a crawl space are an effective tool in combatting moisture. They are often an integral part of your crawl space moisture control system....
Improving Attic Ventilation Improving attic ventilation begins with balanced and distributed airflow in your attic space. This is crucial for combatting moisture and heat buildup. Attics often have variations in temperature and humidity throughout the space. This may...
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 air...
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 moist...
What should my crawl space humidity be? Sounds like an easy question, but humidity is actually a little tricky and sometimes misleading. Why is that? Most people in the crawl space industry often forget that humidity is rH and that “r” is important to remember. It is...
ATMOX focuses on a dew point comparison – not relative humidity. How do you explain dew point vs humidity?
Most research agrees that ideal crawl space wood moisture content should be between 10% and 16%. Wood moisture levels will vary some, but they should not remain too low or too high. It is rare to see crawl space wood moisture levels too low, but it can happen in cases...
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 is...
