The only good way to clean them is in the dishwasher, and I can only fit one
cell in at a time, and I have to move everything around to do that. (The
PITA I referred to.)
You can do an okay job by soaking in a bowl with hot water and detergent
(also a PITA; consider the size of the bowl and then the mess from rinsing
and drying) or a so-so job outside with spray cleaner and a garden hose.
I now use thick pleated disposable filters. I expect the electrostatic ones
are better, but I can't tell the difference.
My new electrostatic filter consists of a metal screen, a
fiber batt, metal screen, fiber batt, metal screen with
power supplied to the metal screens. It cleans the air far
better than my old Honeywell type (aluminum fins, and power
wires), which was indeed a pita to clean. You are supposed
to use new batts and change the filter at least once a year,
twice a year implied, but I change the the batts every 1-2
months, wash the batts in detergent in a sink, and reuse the
batts at least 4 times before throwing them away. Overall,
the new filter is the way to go.
I clean my old Honeywell cells in one of three ways:
* A quick rinse in the dishwasher using the rinse & hold cycle
* Spraying the cells with a degreaser liquid (the on I use is called Siege)
then using a garden hose to rinse them off
* Going to the carwash and cleaning the cells (being sure to not get close
enough with the wand to bend the fins).
With any method - I ensure the cells are dry before turning the power back
on - this usually takes 5-6 hours with the cells back in the furnace & the
fan turned on.
Yeah. By that I mean the Honeywell unit is a just the
filter other than the metal box that fits in the air
plenum. So yes it is a whole different unit. My old
Honeywell unit was about 22 inches square and 6 inches
thick. My new unit is 20 x 20 inches and about 1 inch
thick. It fits in the same space as a regular 20 inch
square paper filter. The power supply is just one of those
small plug in units that produces 24 volts. This obviously
converted to direct current high voltage by a small
electronic board on the side of the filter unit.
