Since air pollution comes from both indoor and outdoor sources;
Step 1 is to seal up the home to prevent outdoor pollutants such as dust, pollen, and odors from entering.
Step 2 is to bring in the correct amount of fresh, clean air of the proper humidity.
Step 3 is to regulate humidity.
The Centers for Disease Control and Prevention (CDC) recommends keeping interior humidity below 50% to eliminate the possibility of mold growth. Most mold species require 70% or higher relative humidity levels to grow.
Conversely, when the humidity levels are too low; viruses flourish. Commenting on recent research, WebMD reports: “By raising indoor relative humidity levels to 43 percent or above, investigators reported that they were able to quickly render 86 percent of airborne virus particles powerless.” As most homes experience dry air in the winter months, is it any wonder that the winter is also when cold and flu symptoms are at their peak?
Humidity control strategies will differ for every home, climate, and family. This site goes in depth describing problems and solutions with high and low humidity.
The bottom line is this: Humidity can be controlled much more readily when uncontrolled air is not freely moving in and out of the home. In fact, you will find that the air in your new home remains comfortable all year around: not so dry in the winter that you have itchy skin, and not so moist in the summer that you feel clammy.
Step 4 is to filter the air.
All of our homes are filtered to at least MERV 13, which can filter out most mold spores, bacteria, and smoke. Optional filtration up to MERV 16 is available. That is as pure as a hospital surgical room!
The health benefits of an airtight, well ventilated home are significant, and undisputed. Whether certified as a Healthy House by the American Lung Association or simply well planned, building with R-Value will offer the highest levels of indoor air quality. It could change your life!
