According to The Environmental Protection Agency, indoor air pollution is one of the key contributors to overall health problems that should be addressed by the home building industry. Over the past several decades, new building codes and energy conservation needs have created increasingly tighter construction standards. This has put greater demands on functional ventilation and relative humidity (RH) control. High humidity is the primary catalyst for the growth of mold, mildew, fungus and other airborne pathogens.

The nation has experienced an increase of asthma cases by nearly 60% in the last thirty years. In a study by the state of Massachusetts, researchers found half of all illnesses can be traced to poor indoor air quality. Homes in the southeastern states—Florida in particular—have a much higher degree of humidity to deal with on a year-round basis. The problem is real.

Solution: Sustain RH at 45-55%

While the math and biology supporting lower humidity is easy to quantify, the technology to master the problem has been relatively elusive—until now.
