Before the onslaught of COVID-19, the building industry was already developing procedures and products for improving indoor air quality. Building envelopes have become much tighter as triple-pane windows, insulated garage doors, and energy recovery ventilators became more common in new homes and remodeling projects.

As concerns about interior air quality become more intense, builders and developers may be called upon to provide answers about how healthy their new homes and apartments actually are. Filter companies and HVAC manufacturers have already started to make products that will help them make their mark on the healthy homes of the future.

According to the U.S. Environmental Protection Agency, Americans spend 90% of their time indoors, and indoor air is typically two to five times more polluted than outdoor air.
