QUESTION:I am conducting a survey on your opinions as to what to install for an
inline slide-in filter to replace the throw-away pleated type currently in our
oil-fired furnace. The furnace system has a 2-speed fan (on 'low' at all
times).
ANSWER: That's what I'm planing to do. This is what the Honeywell literature says
about them:
They are "two-stage electrostatic precipitators." In the first stage, dust
particles enter the charging section of the electronic air cleaner and pass
between high-voltage ionizing wires. Charged to 8000 volts, these ionizing
wires rip electrons from any particles in the vicinity. Particles leave
this section carrying an intense positive or negative charge. In the second
stage, these charged particles enter the collection section and encounter a
series of collector plates. Positively and negatively charged collector
plates shove particles toward oppositely-charged collector plates, while
those same plates exert a nearly irresistible tug on the particles. The
dirty air particles strike the charged plates, where they stick like glue
due to electrostatic attraction until they are washed away.
The back of the booklet lists a typical consumer installed cost of
$550-700. I don't yet own the house I plan to put them in, so I haven't
pursued it further.
Honeywell is at 800-328-5111, though that number may be for portable and
not central.
