Ionizers drift. Maintenance is the anchor.
What actually drifts
Emitter points accumulate contamination, which shifts ion balance and cuts output. Fans in overhead units also collect dust that changes airflow patterns across the workstation.
Balance drift is gradual, so a fixed schedule with recorded readings turns a hidden problem into a visible trend.
FAQ
How often should emitters be cleaned?
Interval depends on the environment's dust load; many programs settle on a monthly check with cleaning as needed. Recorded balance readings tell you when the interval is too loose.
What reading should I expect after maintenance?
Follow the standard your program follows for ionizer balance limits; the trend matters as much as the pass. A unit that sits near the limit every month is a cleaning candidate.
Do overhead and benchtop ionizers need different care?
The physics is the same, but benchtop units collect more handling debris and often need shorter intervals. Keep separate log lines rather than one blended record.
