With more people staying indoors due to Governor Tony Evers’ Safer at Home order, the air you are breathing could be getting worse. According to the Environmental Protection Agency, Americans spend more than 90 percent of their time indoors where the concentration of air pollutants can be two to five times higher than if you were outside. That means you could be breathing in more allergens and other airborne particles over a longer period of time. Ultimate Air owner Jeff Blemke says although you cannot control what is floating around outside, having a high-quality filter for your home’s heating and cooling system could limit the harm you are breathing inside.

Blemke says people living in older homes tend to not have the same issues because they are built more energy-efficient, which limits the amount of air exchanged through walls and windows with the outside.
