Review on 💨 IonPacific ionMi: Powerful Wearable Negative Ionizer - 20 Million Negative Ions/Sec, USB Rechargeable. Say Goodbye to Pollutants, Allergens, Mold, and Germs! by Laura Baker

This is a small device but larger than most portable devices. It comes with a bracelet but no choker. I thought it would use a carbon fiber brush emitter but the manual says it produces a small amount of ozone which I thought would not come from a carbon fiber brush. Unlike other units, a strong ionic wind is imperceptible, but I agree with the calculated 20 million ions expressed in units per cm3. Also, the manual states that both negative and positive ions are generated, so strictly speaking it is not a negative ion generator. An advantage of emitting both charges is that no collector is required. The box indicates that the device is version 2. Power options are easy to understand and cyclical.
