Why do some factories not use Electrostatic precipitator?

Answer 1

Because it's just another technical gizmo that costs money, uses energy, and has to
be cleaned and maintained. They'll do without it as long as possible, until public opinion
or government regulation force them to add it. Then they'll make sure that all of their
advertising tells you how green and socially conscious they are, while they calculate
what it cost them to add it, and hike the price of their product double that.

Answer 2

Some factories may not use electrostatic precipitators due to high equipment and maintenance costs, limited space requirements, or the presence of alternative pollution control technologies that may be more effective or economical for their operations. Each factory's decision to use electrostatic precipitators depends on various factors such as type of pollutants emitted, regulatory requirements, and economic considerations.

Answer 3

they are highly expensive, they have to be cleaned and maintained, they might seem appealing but the filteration plates need to be replaced often and they are not cheap.
