The problem with electrostatic is they loose efficency fast when they
get dirty, they should be cleaned 3 to 12 times a year. Paper
increases in efficency for particle removal as they get dirtier and
usualy last longer 1 yr.
The so called elctronic ones are high tension element which attracts
dust/pollen and holds it. In my house once a year cleaning is enough.
I was not refering to the paper element ones.

I dont know how dirty you call dirty ,the point is they loose
effectiveness quickly When they are really dirty , they have lost
cleaning ability long ago, where paper gets better. Its just better to
clean them often. Check your blower and furnace to see if you have
buildup , that will help determine if you wash it enough. Also I
beleive they pull around 100 watts For me that would add 85.00 a year
running 12 hrs a day. My large paper filter costs 20.00 and lasts a
year. But true It doesnt run 12 hr , unless its real hot or cold out.
Either way , there is a trade off.
I'm also considering something like this - specifically a standalone
unit for our laundry room. We have a number of cats and the dust of
the litter settles quite heavily in the rooms nearest the laundry
room. I'm thinking this is going to be a pretty demanding environment
for the air cleaner. *Lots* of fine grained dust will probably mean
frequent filter changes. Does anyone have suggestions for a unit that
will stand up to the dust load and for which the cost of filter
replacement wont kill me?
Does it make more sense to put a vent fan in the room to suck the dust
outside? I live in Houston, so it's very hot and humid alot of the
time and I thought the vent might cost me big on the electric bill by
blowing all my cool air out.
