Negative ion generators which employ the discharging method can generate fewer negative ions than they are supposed to do or produce a lot of harmful ozone when the ionizing needles get worn out. Ionizing needles determine the life span of the ion generators.

The life spans of negative ion generators which employ the discharging method are usually determined by the ionizing needles.
Ionizing needles gradually get worn out as a result of repetitive charging/discharging or by chemical reactions.
Worn out needles can lower negative ion counts or produce a lot of harmful ozone.
The life span of ionizing needles is an important factor because it determines the life span of the negative ion generator.
