[Shop-talk] Electrostatic filters?

[Peter Schauss]

Two years ago we replaced our 1958 vintage furnace.  The old system had an
electrostatic filter which I had purchased from Sears and installed myself.
The new system, which includes integrated central air conditioning, has an
AprilAire filter system which uses a pleated paper element about 8 inches
thick.  The manufacturer's instructions recommend replacing the filter NO
MORE than once a year and claim that its filtration efficiency actually
improves with use.  From a subjective point of view, we have not noticed a
significant difference in the amount of dust in the house since we installed
the new system.

As another data point, when we would turn on the old system for the first
time in the fall we would get a sort of burning smell which I assumed was
from the dust which had settled on the heat exchanger during the summer.
The new system does not do this which leads me to conclude that the new
filter is doing what it is supposed to do.

I should qualify all of this by saying that my wife's allergies are such
that we never have doors or windows open at any time of the year.

HTH,
Peter Schauss
