It is no surprise that this HEPA filter maker has a chart
showing HEPA filters outperform electrostatic filters:

My guess is that a cleanable electrostatic filter IN FRONT
OF a HEPA filter helps the HEPA filter last longer,
reducing revenue for HEPA filter manufacturers.
I also assume that an electrostatic filter is easier to
pump air through, prolonging fan motor life and reducing
electric power costs. I also assume that an electrostatic
filter makes ozone, and that its high voltage supply can
fail and perhaps catch fire.
That's life; nobody gets off the mudball alive.
