Should I feel good about the change? Will the new filter catch the
ultra-fine particulate matter that an electronic cleaner claims to?
Thanks!
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.

Hi,
One thing air, flow rate will be less with filter.

They do a good job. Can't tell if if they are as good because the stuff
they pass is too small to see.
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
filters.
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!

The cells use DC high voltage at 7,000 to 10,000 volts to capture dust
and other fine particles. The higher the voltage and the closer the
plates are, the better the filtration gets. The trouble is when the
voltage gets too high for the plate spacing, the voltage arcs from the
ionizing wires to the plates and you get snap, crackle and pop in your
filter, which can be quite annoying.

IOW.... is it best to not even use such portable
electronic air cleaners?
I have never seen one with an alarm or meter.

Hi Greg, hope you are having a nice day

I have Greg but it is an add on.

I tried inserting a 4" pleated filter in place of the electronic cells,
but this restricted air flow too much. They are also relatively
expensive, especially if you are replacing them often.
My unit has two slide out mess filters and I have removed each of them
and replaced them with disposable filters. The first filter is one of those
extremely inexpensive filters which has a very loose weave fiberglass
material. The second filter is a medium quality pleated filter. So, I
now have return air flowing through a very inexpensive disposable filter,
then through the electronic cells which are no longer turned on, then
through a pleated filter, and then finally on to the furnace blow fan
compartment. This works extremely well for me.
I leave the electronic cells in place just because they are necessary
for holding the disposable filters in place.
About every 2 weeks I remove the disposable filters to examine them
and to quickly clean them. The shop vac will remove a lot of dirt from
the filters. A blow gun hooked up to my compressor removes much
of the remaining dust when I reverse flush the filters. I use a high volume,
low pressure blow gun - the sort which draws in ambient air through 4
venturi openings.
My cleaning procedure takes very little time once every two weeks.
Obviously, I pitch the filters when the are no longer servicable. The
pleated filters in particular tend to get loaded with deeply embedded
dirt. I clean or replace the filters every 2 weeks because we run the
furnace fan 24/7, mostly for allergy relief.
Good luck,
Gideon

The reports on electronic air filters isn't encouraging, not worth the
price and maintenance hassle. The expensive pleated filters have
several disadvantages - restricted airflow, the expense and not much
more efficiency in removing dust than the el cheapo. Once the dust
layer forms on the coating it becomnes just an ordinary filter.
My current solution is to spray the el cheapo with a light coat of
cooking oil. Its been two months now but with the warm weather the
furnace had been on less than half a dozen times (night temps. did
drop to single digits a few times.) The filter element is still clean
and the oil coat sticky. No rancidity. I'll know how well this
works when the cold season comes around.
