Tighter energy-efficient homes: These homes actually trap moisture, odors, and VOC’s, creating an unhealthy, uncomfortable environment.
Homeowners today are more aware of indoor air quality: People are aware of the issues and the dangers of mold, allergens, etc.
People spend more time in their homes: Hence they breathe more, cook more, add more plants, pets, etc., all of which contribute to creating more moisture in a tighter home.
The Need for Dehumidification
Maintaining a proper humidity level is one of the most important steps in providing a comfortable and healthy home. Excess moisture in the home promotes harmful indoor air particles, including mold, bacteria, viruses, dust mites, allergic rhinitis and asthma. In addition, a home with excess moisture can be uncomfortable – regardless of the temperature.
Over the years, several major changes have occurred in home construction and HVAC system design. Unfortunately with many of these improvements, major issues have developed that now need to be resolved in order to achieve the truly comfortable, efficient and healthy homes that the homeowners envisioned.
