Choosing the right dehumidifier and air filtration system for your basement and or crawl space can improve the health of your home and family.

Would you believe that half of buildings in the United States are water damaged, leading to the growth of mold and the potential for mold illness? Given that most of us spend significant time in a home and indoor workspace, there’s a good chance you’ve been exposed to water damage and mold.

Indoor air pollution is something every home in America struggles with. Since 1970 homes have been built “tighter” to conserve energy. But that same tight construction reduces ventilation, traps indoor air pollutants inside your home and could be making you sick. Here are some facts and statistics regarding your health and your home’s indoor air quality, according to the EPA.

  • You spend about 90% of your time indoors. Weather it is at work, at school and at home, if you are like most people, you spend almost all of your time inside.
  • The quality of indoor air can be two to five times (and even up to 100 times) more polluted than the worst outside air. Most people recognize the health concerns of outside air pollution, but few consider that exposure to poor indoor air quality has the same ill health effects.
  • The EPA has ranked indoor air pollution among the top five environmental dangers.
  • Over the years, there has been an alarming increase in the number of children with severe allergies and asthma. Allergies, asthma, lung cancer and heart problems have all been linked to poor air quality by the The American Heart Association.
  • Indoor High Humidity promotes the mold growth - Many studies have shown a link between building dampness and adverse health effects. The larger the extent of the damage is caused by humidity in the building, that increase health risks. These risks and effects range from respiratory symptoms and infections, to chronic diseases, such as asthma and allergy. General symptoms, such as fever, fatigue, headache and difficulty to concentrate have also been reported and associated with indoor dampness.
