Hi all,

I've been hearing recommendations for bipolar ionization, as a way to filter airborne virus particles in HVAC systems while avoiding the energy penalty of increased ventilation. However, I've also heard that ionizing equipment is dangerous because it produces ozone.

Does anyone have any insight into the effectiveness and/or cautions... Read more
