My 30-year-old Honeywell electronic air cleaner stopped working. The
repair man highly suggested that I remove the cells and replace them
with pleated air filters (4"). I did this, but am wondering if it was
a good move or not. The repairman insisted that the pleated media
filter would do a much better job than the electronic unit did,
especially good for keeping dust out of the central A/C.
Should I feel good about the change? Will the new filter catch the
ultra-fine particulate matter that an electronic cleaner claims to?
Define better. Assuming the pleated filter does not produce too much
air resistance and reduce the air flow too much, it should do a very good
job of normal air cleaning, maybe better than your old one in some ways.
Depends. However I have to ask. Does it matter to you? Really. There
are many products on the market that arguably better than others but often
cost more or are less reliable or have some other disadvantage. You need to
weigh the advantages against the disadvantages. Do you really have a
problem caused by those ultra fine particles? It brings to mind the
commercials about the "lurking" germs in the bathroom air. According to all
the independent information I have found, yes there are germs in the air in
the bath, but no more than in the kitchen. They are not a problem, except
in the extreme case.
I replace mine with pleated filters 6 years ago because I got sick of
cleaning the electronic ones.
They do a good job. Can't tell if if they are as good because the stuff
they pass is too small to see.

That would seem to depend on the design of the electronic air cleaner
and we have no specifics. In general, I'd suspect they are not designed
to accept standard filter media, but it's possible it might work in
some. There are measurements for the filters, you can measure the
filter unit. I'd think even if they are close in size, it may not seal
properly around the filter as compared to the electrostatic slide out
part and air would get by, etc.

It will have some more airflow resistance than an electronic, but I've neve
seen a furnace blower that wasn't capable of handling one of the media
type air filters. The reason they are so thick is that they have deep
pleats that greatly increase the surface area.
Try WW Grainger for pleated filter information. They put a good amount of
information about the filters they sell. I use their extended service for
the lower static pressure. Best check with your manufactures of the filter
and the a/c see what levels of static your system can handle. My a/c pretty
much craps out when 0.70 of static pressure is reached. Some filter
companies tell you to change the filter at 1.0.
Depending on the media pleated filters are far superior to electronics. Have
you ever seen a clean room with a electronic filter? They use Hepa pleated
I do HVAC service for a living. I have yet to see someone service an
electronic air filter often as they needed to. Once the electronic elements
get dirty the filter does nothing. When in use, cooling or heating season,
electronic filters need cleaning at least once a month to do the job. A
pleated filter in place of the electronic elements is a very good idea.
When I notice that a customer has an electronic filter I ask them how often
they clean it. Most are surprised that once or twice a year is not enough!
I agree; coincidentally, the other day, I picked, up for scrap, a used
electronic filter unit.
It appeared to have 'never' been cleaned!
The slide out electronic filtering units were literally jammed with
felt-like lint, comprised of human hair, even a few feathers and some scraps
of tissue paper! Maybe the building it came out of had included a hair
Anyway the air flow through it must have been virtually nil. With the
electronic filtering action completely negated by the mass of debris.
Curious about how these things work, I removed the mess from one part of the
unit to view the electrostatics and had to use a knife to cut through the
mats of lint, section by section.
By the way it has as a 120 volt 60 hertz AC input 'transformer'. The output
of that, is connected to the electrostatic section, at presumably, a high
voltage. But is that electrostatic section operating at AC or DC? In other
words does the unit 'labelled transformer' also incorporate a rectifier to
convert AC to DC?
Electronic loose efficiency as they get dirty and at my electric rates
125kwh can cost 12$ a month to run 24x7. They need to be kept clean.
Media gain efficency as they get dirty but are more air restrictive
clean and more so dirty. A pooly designed system may freeze the coil
with the media reducing airflow if you dont have a pro check present
coil temp and calculate air flow reduction. My system is oversized so I
welcome reduced summer airflow as it removes more humidity. I like
Media, April Air 2200 Medias case does not seal positively, look into
Air Bear. Or for a fancier super cleaner April Air or Lennox has a new
unit out that is electronic and media. Just my non professional opinion,
