The new tool shows how much certain actions can lower residents' risk of exposure.

There are several measures that, combined with vaccination, could curtail a new wave of infections. One often-overlooked approach for homes is managing air flow and air cleaning. Leveraging ventilation and filtration has been an underutilized strategy for many residents throughout the pandemic because of the technical know-how required to implement these strategies. To help more people use this approach effectively, researchers at the National Institute of Standards and Technology (NIST) have developed a simple interactive webpage featuring the new Virus Particle Exposure in Residences (ViPER) tool. With ViPER — and some basic knowledge about their homes — homeowners and renters can learn how much certain actions, such as upgrading air filters or opening a window, may lower their risk of exposure to particles in the air that could potentially transmit COVID-19.
