This miniature negative ion generator produces 4KV ±0.5KV and over 3 million negative ions per cubic meter (measured 12" from source). Negative ions provide many benefits of cleaning the air of dust, smoke particles, certain pollutants, pollen, mold and even particles such as bacteria and viruses according to research. They have a relaxing effect and are even found in deluxe hair blow dryers. A negative ion is an oxygen atom charged with an extra electron. This 120VAC negative ion generator was custom made for us and is easy to use. Just connect red & black lead to 120VAC (no polarity needed). White wire has a carbon brush attached that emits the ions. Size only 0.71" length X 0.47" diameter. Lead length about 12". Brand new.
Note: Line cord sold separately - not included.
