Glad to see these things are spreading. I’ve been using a high frequency (nikola tesla invention) for years. Produces ozone as well as the HF. Either the ozone or the high frequency current or both just decimate viruses and bacteria immediately. Instantly. (Petri dish- microscope research proves it). The FDA banned them for medical use back in the 50s but they are still sold just not as health products.

There’s a lot of them on the market you just have to try to get one well-made/ strong enough. And an American company.
