Works well in HVAC - Air Ionizers

My brother is a licensed HVAC guy. He recommended this when COVID started. I had a similar one once, but it didn't work. I'm not sure if it kills germs, what are you saying? However, it reduces the amount of dust. Grandkids and dogs run around, quickly gathering dust on my black piano and everything else. First look at the piano. I haven't cleaned it for a week, everything is fine.
