Two ISO-Aire RSF1000 units engineered with medical-grade HEPA filtration and ozone-free bipolar ionization flank the sanctuary entrance at Calvary Evangelical Free Church. An ionization meter (right) measures the output of positive and negative ions, which work in two strategic ways to capture and destroy microscopic pathogens and contaminants.

Toward the back of the sanctuary at Calvary Evangelical Free Church (CEFC) in Rochester, Minn., two powerful ISO-Aire units are in place protecting this longstanding community of faith and service. The supplemental in-space air purification floor models complement the church's existing HVAC and air handling system, adding a proven layer of protection for members during worship services.

"Our congregation is pleased to see that we are doing as much as we can to mitigate the spread of the virus and having the two units in our space really sends that message," explained Joel Minchinton, CEFC facilities manager.

ISO-Aire delivers proven mitigation strategies that exceed the minimum requirements for indoor air quality established by ASHRAE and the Centers for Disease Control. Easy-toinstall and maintain, ISO-Aire in-space purification solutions are helping to clean the air and protect occupants in schools, restaurants, fitness studios, senior living centers, day care facilities, and more.
