JUST IN TIME for the High Holy Day crowds, a pair of air purifiers was installed yesterday in our historic sanctuary’s HVAC system—one for each blower. These devices use needlepoint bipolar ionization (NBPI) technology, as described HERE—from when we were preparing to install one in our school building.

As long as the HVAC blowers are on, these purifiers will be generating ions that the fans are casting out into our large hall, where the ions can neutralize airborne viruses and bacteria right where people are sitting—without needing to wait for the air to recirculate to the HVAC filter. Hence I believe that these devices will be significantly reducing the airborne transmission of disease inside our sanctuary.
These ion generators are designed for a system that is up to 2.4 times as large as ours. That’s good, because our retrofitted system is only about half the size needed when the sanctuary is full of people. In other words, our air purifiers are properly sized for the space.
For links to evidence that the ions produced by this device are indeed effective at neutralizing airborne pathogens directly, see HERE.
