A study completed by the International Energy Agency (IEA), Capturing the Multiple Benefits of Energy Efficiency, examined health outcomes resulting from energy-efficient measures completed by residential homeowners. A number of efficiency measures were studied, including insulation, air sealing, heating systems, and ventilation. Results from every type of measure indicated “reduced symptoms of respiratory disease,” and “ventilation” improvements also indicated a reduced risk of cancer, cardiovascular disease, arthritis, and depression.
There are a number of upgrades that can be made to a home’s heating, cooling and ventilation system that will remove stale air and provide a continuous supply of fresh, filtered outdoor air. Whole-house air-filtering systems are very powerful and can serve as a year-round defense from a broad range of biological pollutants such as dust, dander, pollen, bacteria, mold, mildew, and viruses. Whole-house systems are duct-based and integrated within the heating, ventilation, and air conditioning (HVAC) furnace.
Scientific advancements in ventilation systems are now able to capture far greater levels of bacteria, allergens, and airborne pollutants. Your family can benefit from a continuous supply of fresh, filtered air just by making a few changes to your heating, cooling, and ventilation system.
