[RH77]

After 9 years of faithful, continuous service, my HEPA filter fan finally died. It filtered it's last particle of allergens. Services will be held Tuesday.

I never used it, but it came with an "Air Ionizer" feature -- basically a series of prongs that negatively charge the outgoing air (with the idea of making particles stick to the filter media easier). The downside is heavy-duty dust sticking to the room's surfaces -- so it was never used (plus the idea of air pollution).

In an effort to repair the motor that gave out, I dismantled the unit...

Caution: Do not attempt: high voltage equipment inside.

Disassembling the unit showed the failing motor, and an interesting inverter Input: 120VAC, Output: 7000VDC-Negative. Precautions were made to ensure full discharge before removal.

Is there a practical use for this kind of high-voltage device? I got the motor working again, but the brushes are toast, so the whole thing is doomed for recycling.
