Electrodepot Negative Ion Generator 12VDC – Plasma Ionizer Module with MicroPin Stainless Steel Needles for Static Applications, HVAC & Air Circulation Systems

Working with negative aerial ions is a challenge. Novices need to understand several things. 1) Negative aerial ions are very ephemeral. Creating them is not like releasing a puff of perfume that will remain in the air for several minutes. Once created, negative aerial ions disappear within seconds. 2) Negative aerial ions are strongly attracted to material objects. Hence, ion generators need to be separated from other objects, including support materials such as tables, as much as possible. 3) Most commercial detectors of aerial ions are difficult to work with. Typically, they start by reporting a high value that drifts downwards. The Japanese company Ion-Trading makes a simple detector with a green light that turns on when ions are detected; this yes-no answer makes it the best practical detector that I have found. 4) Most generators of negative ions also produce abundant positive ions. The green-light detector I referred to above will not report this, but Ion-Trading also makes an expensive ($950) detector that reports both positive and negative ions. The 5-pin negative ion generators that this review concerns supply a cloud of negative ions that can be detected 3 feet away when powered by a battery harness containing 8 1.5-volt AA batteries (users will have to wire the connection themselves). These 5-pin generators have an unfortunate tendency to stop functioning suddenly (presumably they burn out); however, given their price, they are overall a good bargain. I…
