Read the report! Electrostatic electronic air filters are only efficient
for a VERY short period of time! After a small amount of dust covers the
filter cell the dust will then pass right through the cell and put
back into your indoor air environment to BREATHE AGAIN AND REACT TO! You
can hear the dust passing through the filter cell as it snaps and pops
which is the arching of the dust as it hits and passes through the cell.
They have to be washed way to often to continue to operate properly.
Thats way a MUCH cheaper self charging electrostatic filter is a better
idea.

I would disagree. True, the efficiency decreases with too much crud.
Some crud and dust actually improves efficiency since the particles
stick better to the allready present particles. The particles are
capable of charging to close to the actual plate voltage. I started to
build my own electrostatic filters after getting some ideas looking at
commercial units. I have spent much time playing with them, including
ion generators and Ozone generators. I have real time experience. I
don't need reports.
