When it comes to ensuring the health of your family, mold is one guest you do not want in your home. Numerous studies have shown a connection between mold and the increased risk for adverse health effects. Mold can lead to mild to severe health problems, including asthma and allergies. Symptoms include runny nose, coughing and wheezing, and red or itchy eyes, or skin irritations. For people with severe mold allergies, the symptoms can be worse. And for those with weak immune systems, who are already at risk, it can lead to infections in their lungs. What causes mold in your home? In one word – moisture. Moisture can come from many sources, such as water from storms, condensation, leaky pipes or high humidity. So how do you prevent or reduce moisture? One way is through use of ventilation, which is the circulation of air via natural means, such as open windows, or mechanical means, such as fans. While there are many types of fans available, many professionals recommend a whole house fan. This is an exhaust system that is specifically designed to circulate air in your home easily and effectively. Whole house fans are located in the attic so that they suck air into the home. The fans cool and ventilate your home by pulling cool, fresh air through open windows and doors and then disperse the hot, stale air through the attic or roof. The fans work similar to vent fans that many of us have in our kitchens and bathrooms – just on a larger scale to remove stale air and moisture and replace it with fresh air. Whole house fans typically provide 30 to 60 air changes per hour. These air changes are critical to ensuring good indoor air quality in homes. Today’s houses are built with tighter envelope than those in the past to ensure energy efficiency. However, that tightness means less opportunity for natural ventilation or stale air to escape and for good air to enter. Picture a whole house fan as a giant broom that is sweeping away the dirt while leaving behind a clean, scrubbed floor. Which would you rather walk on? Exactly. And which air would you rather breathe? Use of whole house fans helps ensure good indoor air quality and reduces the risk of moisture. And while you cannot get rid of all mold and mold spores in your home, reducing and controlling moisture is a critical first step to reducing mold. Whole house fans also have other advantages. They can help lower your energy bill, cooling your home for about $0.07 an hour. Unlike the fans of yesterday, today’s fans are ultra-quiet. If you are looking to ensure a healthy home with better air quality and fewer odors, consider a whole house fan. Call Enver Energy Improvements today to learn more.
