What educators are saying about the PuraShield 500

Having a Purafil unit in each classroom provides our teachers with more peace of mind by enhancing the safety of our classrooms. They are also providing peace of mind to our students and their families. We are grateful to add cleaner air to the list of precautions we are taking to ensure that Chicago Jesuit Academy is a safe learning environment for all of our students.

Ms. Anne Durkin, Dean of the Lower School

What experts are saying about the threat of aerosols

We now know with greater clarity that this virus can be transmitted, not just by droplets that can be blocked by plexiglass barriers, but my aerosols that can hang in the air and travel on air conditioning currents.

Dr. Jonathan Reiner, Professor of medicine at George Washington University - recently quoted in CNN

Testing Update: 99.999% reduction in 30 minutes

When tested against the MS2 bacteriophage, a surrogate traditionally used for influenza … the device showed a high net log reduction in a relatively short amount of time [that] equates to over a 99.999% reduction in viable MS2.1
